Implementing Security, share II: Hardening Your UNIX/Linux Servers | killexams.com real questions and Pass4sure dumps

Continuing with share 2 of this two-article series, Joseph Dries helps you continue to expand upon your list of basic security processes by looking at UNIX/Linux hardening, protecting your servers from network based TCP/IP attacks, and utilizing centralized logging servers.

This article was excerpted from The Concise usher to Enterprise Internetworking and Security.

"A commercial, and in some respects a social, doubt has been started within the eventual year or two, whether or not it is privilege to debate so openly the security or insecurity of locks. Many well-meaning persons suppose that the discussion respecting the means for baffling the supposed safety of locks offers a premium for dishonesty, by showing others how to be dishonest. This is a fallacy. Rogues are very keen in their profession, and already know much more than they can train them respecting their several kinds of roguery. Rogues knew a fine deal about lockpicking long before locksmiths discussed it among themselves, as they own lately done. If a lock—let it own been made in whatever country, or by whatever maker—is not so inviolable as it has hitherto been deemed to be, surely it is in the interest of honest persons to know this fact because the deceitful are tolerably certain to be the first to apply the lore practically; and the spread of lore is necessary to give unbiased play to those who might suffer by ignorance. It cannot be too earnestly urged, that an acquaintance with real facts will, in the end, be better for sum parties." —Charles Tomlinson's "Rudimentary Treatise on the Construction of Locks," published around 1850

It has been said that the wonderful thing about standards is there are so many to pick from. The same selection is available in the UNIX arena. There are two basic flavors, BSD-derived and AT&T System V-derived. BSD-derived UNIX systems embrace OpenBSD, FreeBSD, NetBSD, BSDi, MacOS X, and SunOS 4. System V-derived UNIX systems embrace HP-UX and Solaris (SunOS 5). Other UNIX systems, such as AIX, provide commands that will act BSD-ish or System V-ish, depending on how they were invoked. Linux is not derived from any UNIX, but depending on the distribution, borrows from both BSD and System V semantics. Actually, Linux itself is just the operating system kernel and supporting drivers. Most Linux distributions exercise the GNU system (http://www.gnu.org), thus they are called GNU/Linux distributions. There are hundreds of available GNU/Linux distributions, but even the "top 5" are different in their default commands, startup scripts, filesystem layout, included utilities, and packaging systems.

What does this insinuate to you? Unlike Windows NT, including Windows 2000, it is a far more complicated process to characterize how to acclimate a UNIX/Linux server. This next section provides some common procedures that can be applied across UNIX versions and GNU/Linux distributions. Following that are some pointers to alive documents on the Internet, which track available data and releases, and proceed into a more minute account of how to acclimate a server for a particular task.

Common Steps for Hardening UNIX/Linux Servers

The process of building a UNIX or GNU/Linux server for exercise as a firewall or DMZ server begins with installation. Eliminating points of attack, such as filling the filesystem, or removing unnecessary libraries and services, is equivalent to removing feasible entry points for intruders.

Some common guidelines for configuring UNIX servers with a more secure default stance are available from CERT's Web site at ftp://info.cert.org/pub/tech_tips/UNIX_configuration_guidelines.

Besides having divorce partitions for the obvious, such as SWAP and /tmp, you should protect against out-of-disk-space denial-of-service attacks. Intruders might try to create inordinate generation of logging data or fill your file system with large files through FTP or mail spool. The best pass to protect against this is to segment the filesystem hierarchy into divorce physical partitions.

The root partition / can be diminutive because it generally contains just the kernel—the necessary files, libraries, and configuration for booting in /bin, /sbin, /etc, and /lib. Access to the attached devices is provided through the /dev and /devices directories. Many GNU/Linux distributions store kernels and symbol data in the /boot directory, whereas kernel libraries are stored under /lib.

The /usr partition is normally where user-accessible applications are stored. Normally, /usr does not accommodate data or configuration files that change; therefore, an added security measure can be mounted as read-only.

The /var partition stores system logs and data services such as mail, Web, databases, printing, running services, package management, and so on. On a mail server, you might want to win /var/spool/mail, or /var/mail in Solaris, a divorce partition, or—even better—a divorce disk array. If you only create one divorce partition from /, /var is the one you should separate.

The /usr/local directory structure, and in Solaris the /opt directory, often contains locally installed optional software, configuration files, and data. /usr/local is normally not affected by operating system upgrades. Depending on how you exercise those directories, they too can be mounted as read-only.

These are suggestions and guidelines only, and are different from recommended settings for a system that contains user accounts, usually in /home.

Disable Extraneous inetd Services

inetd is the UNIX "Internet Super Server." It is a daemon process that is invoked at boot time and reads in a flat file configuration database normally establish at /etc/inetd.conf. inetd listens for incoming connections on the defined IP ports. When a connection is initiated on a defined port, it invokes the configured program to service the request. After the connection is finished, the process invoked to service that request terminates. This was originally designed to lighten the load and resources required for systems.

There are a number of services enabled through inetd, and almost sum of them should be disabled for building firewalls and DMZ servers. Besides normally disabling FTP, TFTP, Telnet, and the Berkeley r* commands, disable the following:

  • in.named—BIND designation services daemon. Except for your DNS servers, you should not be running DNS on your firewall or DMZ servers.

  • in.fingerd—Finger daemon that can be used to explicate user information and lists of users who are logged in. There is no reason to advertise that information to would-be intruders.

  • daytime—Connections to this service panoply the date and time on the system in a string format. Getting the date and time of a system is useful for an intruder trying to implement replay attacks.

  • time—Connections to this service recrudesce the time as a 32-bit value representing the number of seconds since midnight 1-Jan-1900. carry out not provide intruders with your exact system time.

  • echo—This is a diagnostic service that echoes incoming data back to the connecting machine.

  • discard—This is a diagnostic service that does not resound (thus discarding) the incoming data stream back to the connecting machine.

  • chargen—This is a diagnostic service that automatically generates a stream of characters sent to the connecting machine.

  • systat—Connections to this service provide a list of sum processes and their status.

  • netstat—Connections to this service provide a list of current network connections and their status.

  • Install and Configure tcp_wrappers

    Install and configure Wietse Venema's tcp_wrappers on both your firewall and DMZ servers. tcp_wrappers allows you to define access control to various services, depending on a limited set of criteria, such as username, IP address, or DNS domain.

    You might be asking why it's necessary to configure and install additional products when your firewall will be doing the same thing. And that's a telling question. The reply is to avoid separate points of failure, and to provide security in layers. If one layer is pierced and bypassed, other layers will be standing guard behind the breach.

    tcp_wrappers are lightweight and extremely useful on internal servers; not just on firewalls and DMZ servers. hold in humor that most information security breaches, intentional or accidental, betide internally. It's only the external defacements, massive distributed denial of service (DDoS) attacks, virus-du-jour, and stolen credit card databases that grab the press. That, and misplaced difficult drives with highly sensitive nuclear information.

    tcp_wrappers own two main files that allow access to the individually defined services. The following two files are checked for rules governing access to individual or wildcard services:

    /etc/hosts.allow /etc/hosts.deny

    Like most firewalls, access is granted or denied on the first matching rule. The rules are checked in order, first in hosts.allow and then in hosts.deny.

    Care should be taken when using the KNOWN or UNKNOWN wildcards. sum will always match whatever criteria you are testing. Read the hosts_access manual page included with tcp_wrappers for further details on syntax and rules setup.

    tcp_wrappers is installed and configured by default on most GNU/Linux distributions and BSD releases. For those UNIX systems that carry out not own tcp_wrappers installed by default, they can be establish at ftp://ftp.porcupine.org/pub/security/index.html. Retrieve the source, compile, and install the binaries on the servers.

    Lock Down Your DNS Server

    The Berkeley Internet designation Daemon, or BIND, is the reference implementation of the designation service providing DNS for the Internet. The Internet Software Consortium (ISC) is accountable for implementing and maintaining BIND. There are three basic versions of BIND: BIND 4, BIND 8, and (recently) BIND 9.

    BIND 4 has been around forever, and has its share of exploits. Only very traditional versions of UNIX systems and GNU/Linux distributions came with BIND 4. Still, you'll be surprised how many installations quiet own the older BIND 4 running. You should upgrade to a newer version of BIND. The unfortunate thing is that the file format defining the zones served by the server has changed. There are conversion scripts, but there is sure to be some hand editing.

    BIND 8 is the current stable release, and offers many more features and better control and granularity in access control. The settings described later are discussed with BIND 8 in mind.

    BIND 9 was released late in 2000. It offers many unusual features, such as IPv6 support, DNSSEC, plenary Dynamic DNS, incremental zone transfers, multiple views (internal, external, and so on) from a separate server, and scalability improvements. If any of those features are significant to your configuration, you should investigate using BIND 9; otherwise, it's best left to the adventurous.

    Although almost sum UNIX systems and GNU/Linux distributions approach with BIND as the designation server, it is significant you win sure you are at a recommended release. Before deploying a DNS server, internally or on the DMZ, win sure it is at least version 8.2.2-P5. Any version prior to that has serious exploits. This warning should not be ignored. The Internet Software Consortium themselves own issued a statement that if you are running any version of BIND prior to 8.2.2-P5, you should assume your server has already been compromised. Check your UNIX system or GNU/Linux distribution. If the version of BIND is not at least 8.2.2-P5, check with your vendor for upgrades. If an upgrade is not available, you can compile a version of BIND yourself on a workstation, and install the binaries on your server. The source code can be establish at http://www.isc.org/products/BIND/.

    First, restrict zone transfers to specific secondary servers in your primary zones. The acl command allows you to define an access control list composed of blocks of addresses to be used with a named identifier. Using ACLs provides a self-documenting manner of administrating the named.conf configuration file. In the following example, they define two ACLs comprising their externally visible DNS servers and the secondary servers at their ISP:

    acl your-company-dns { 172.16.30.12; 172.16.30.24; }; acl your-ISP-dns { 199.177.202.10; 204.95.224.200; };

    The following allow-transfer option directive placed in your named.conf file will default sum defined zones to only allow transfers for the defined hosts:

    options { allow-transfer { your-company-dns; your-ISP-dns; }; };

    You can override the allow-transfer statement in the options directive by placing the allow-transfer statement in the zone definition:

    zone "yourdomain.com" { sort master; file "db.yourdomain-com"; allow-transfer { 172.16.30.12; 192.168.71.200; }; }

    The default allow-transfer option will preclude zone transfers to hosts not specified in the ACLs. However, if you want to restrict sum zone transfers on your secondary servers and any secondary zones on your primary servers, exercise predefined match list none. This can be accomplished with the following allow-transfer directive in your zone definitions:

    zone "yourdomain.com" { sort slave; file "db.yourdomain-com.s"; masters { 192.168.71.1; }; allow-transfer { none; }; };

    Finally, because you will be allowing recursive queries through your servers, it's best to enable access control lists for your internal networks. Using a nested, named acl with the allow-query option in the zone definition, you can then restrict recursive queries to internal hosts only as seen in the following example:

    acl internal-net { 192.168.71.0/24; }; acl dmz-net { 172.16.30.0/24; }; acl trusted-hosts { localhost; internal-net; dmz-net; }; zone "yourdomain.com" { sort master; file "db.yourdomain-com" allow-query { trusted-hosts; }; };

    Que's Concise usher to DNS and BIND by Nicolai Langfeldt is a wonderful resource to further grok BIND configuration and maintenance.

    Tighten Sendmail Default Options

    Send mail comes with just about every UNIX/Linux installation as the default mail transfer agent (MTA). As a result of being so widely installed, it has been estimated that sendmail handles a majority of the email on the Internet. Because it runs as suid root, sendmail exploits impress millions of machines.

    sendmail version 8.11.0 is available at the time of publication, and supports unusual features such as STARTTLS and SMTP AUTH encryption. Upgrade to the newest version available, if possible, but gratify win sure that you are running a version no later than version 8.9.3 because of security exploits.

    To enable the Realtime Blackhole List feature, exercise the following in your sendmail.mc file:

    FEATURE(rbl)dnl

    Additionally, you might want to disable the SMTP VRFY and EXPN commands in sendmail. These commands are often used by intruders to amass information about your system:

    define(´confPRIVACY_FLAGS', ´novrfy,noexpn')dnl

    There are several additional flags you can set to win sendmail own a more secure stance:

  • authwarnings—Add X-Authentication-Warning header in messages on certain conditions that might argue mail system spoof attempts.

  • needmailhelo—Require that the sending site uses the SMTP HELO command first when connecting to ship email.

  • needexpnhelo—Require that the sending site uses the SMTP HELO command before allowing any EXPN usage.

  • needvrfyhelo—Require that the sending site uses the SMTP HELO command before allowing any VRFY usage.

  • noreceipts—Disable Delivery Status Notification (DSNs) of delivery and read receipts.

  • goaway—Set sum flags except restrictmailq and restrictqrun.

  • restrictmailq—Prevent users from using the mailq command to view the contents of the mail queue.

  • restrictqrun—Stop users from processing the queue.

  • Better than sendmail: Making Postfix Your MTA

    According to its Web page, Postfix's goals are "to be fast, simple to administer, and secure, while at the same time being sendmail compatible enough to not upset existing users."

    Postfix was primarily written by Wietse Venema of tcp_wrappers fame. Postfix was designed to be modular, thus Postfix is not a separate executable like sendmail; rather, Postfix comprises a collection of specialized programs that achieve specific tasks. sum the programs except for the master control process (oddly called master because it runs without root privilege) sprint as nonprivileged users, limiting the damage an attacker can inflict on your system. Because of the speed, ease of configuration (and thus less desultory of misconfiguration), and security, it is recommended that you investigate replacing sendmail with Postfix. For those of you who carry out not dream in sendmail.cf syntax, Postfix will win email administration both easier and more secure.

    Postfix is now distributed with most GNU/Linux and BSD releases, although it is not often installed by default. Usually, it is a simple matter of installing it via your package management system, or (in the BSD case) via the ports collection.

    If you are using an operating system that does not ration Postfix, desperation not. You can download and compile the sources easily on a evolution workstation and then install the binaries on your mail server. The sources, FAQs, and documentation can be establish at http://www.postfix.org/

    Linux-Specific Tasks

    There are many GNU/Linux distributions out there. Each vendor has its own installation process, which usually changes between unusual versions of the vendor's distribution. The "forerunners" of GNU/Linux distributions are Red Hat, SuSE, TurboLinux, Mandrake, Caldera, Slackware, and Debian. That does not insinuate specifically that you should exercise any one of them because the high number of distributions allows vendors to tailor their GNU/Linux distributions to specific tasks such as embedded systems, routers, and firewalls. remove the time to carefully investigate the available distributions, and determine which best fits your needs.

    With that said, two of these common distributions stand out, but for different reasons. Red Hat, because it has had the most designation recognition, and is usually the first to Get any sort of corporate advocate in the pass of commercial software or commercial technical service. Many vendors, such as Oracle, IBM, and Check Point, own released products for Red Hat-specific distributions. This does not insinuate that those software releases will not sprint on other GNU/Linux distributions, but if there is a problem, the vendor might not advocate your installation of its product on a non-Red Hat distribution.

    Debian is the second distribution that deserves mention. First, not because it is entirely free, but because it is maintained by a nonprofit organization made up entirely of volunteers. These volunteers are highly motivated by trait and pride in their efforts to win Debian the most stable and completely 100% free distribution available. Debian has proven to be extremely stable and simple to manage and upgrade remotely. The upgrade process is by far the easiest of any of the GNU/Linux distributions. Debian installations can be upgraded without the requisite for reboots, replacing every installed package and running process excepting the kernel. Additionally, the Debian packaging system and its front ends allow extremely fine-grained control over which packages, utilities, libraries, and files exist on your system. Debian also is currently available on six different architectures, with more than 3,900 included software packages to select from when installing.

    For both Debian and Red Hat installations, you should pick custom installations, and select the individual packages you want on your system. There should be no requisite to install evolution packages, any of the unusual KDE or GNOME desktops, and certainly not X Window. Unfortunately, neither distribution yet has a minimal secure server or firewall predefined install-set.

    During the installation process, you should pick to enable shadow password file support; pick to exercise MD5 hashes for the passwords rather than the everyday crypt function. If you miss these options during the install, you can change them after installation. In Red Hat, exercise the setup utility. In Debian, you can exercise the shadowconfig utility to enable or disable shadow passwords. To enable MD5 hashes, you own to edit the appropriate files under /etc/pam.d to embrace md5 on the password lines.

    You should also enable ipchains support, even if this is an application server on the DMZ. ipchains provides additional layers of security, and allows you to protect the server from traffic should the firewall fail for some reason. A sample ipchains configuration is discussed later in the article.

    You should additionally read and monitor the security and errata/updates lists from your distribution vendor. With Debian, it is extremely simple to automatically install security updates using the apt-get utility. For Red Hat installations starting with the 6.0 release, there is the up2date utility to retrieve updated packages for your release.

    For those people who pick to install Red Hat Linux, there is a security-related project called Bastille Linux, whose even is not just to acclimate your Linux installation, but to educate the administrators on how to acclimate the system. Bastille Linux supports Red Hat and Mandrake Linux distributions with project goals to become distribution, and UNIX flavor, agnostic. The Bastille Linux product is a set of scripts that asks a series of questions and then allows you to apply those modifications to your system. The questions characterize what needs to be done, why it should be done, and why you might not want to carry out it. It is very educational, especially for those administrators just getting close with Linux. Bastille Linux can be establish at http://www.bastille-linux.org/.

    Another excellent source of information for administrators is the Linux Administrator's Security Guide. It covers an extremely wide array of topics related to Linux and security. You can find the Linux Administrator's Security usher online at http://www.securityportal.com/lasg/.

    Solaris-Specific Tasks

    Solaris has four default install-sets: Core, End-User, Developer, and Entire Distribution. Installing any install-set higher than the Core installation will enable more services than are required for DMZ servers or firewalls. In reality, you can often remove a significant percentage of the default Core install-set, depending on your server's application requirements.

    For Solaris-based servers, there are several excellent documents from Sun in its Blueprints Online archive at http://www.sun.com/software/solutions/blueprints/online.html. The following three papers are excellent starting points for building secure Solaris servers:

  • "Solaris Operating Environment Minimization for Security: A Simple, Reproducible and Secure Application Installation Methodology" by Alex Noordergraaf and Keith Watson. Although this paper specifically covers the iPlanet Web server requirements, similar requirements are necessary for using Apache or other Web servers.

  • "Solaris Operating Environment Security" by Alex Noordergraaf and Keith Watson. An overview of common security options on a Solaris server. This paper includes some specifics for the SPARC architecture; however, most of the material is applicable to Intel architectures as well.

  • "Solaris Operating Environment Network Settings for Security" by Alex Noordergraaf and Keith Watson is another excellent paper on kernel tuning and application parameters that impress network security.

  • As a matter of fact, Sun's Blueprints Online is a wealth of whitepapers outlining Best Practices regarding Solaris Operating Environments, whether it is a DMZ Web server, firewall, or internal highly available database cluster.

    Lance Spitzner also has an excellent Solaris hardening document that details the hardening process for building a Check Point FireWall-1 firewall on several recent versions of Solaris (through version 8) for the Intel and SPARC platforms. The alive document resides at http://www.enteract.com/~lspitz/armoring.html.

    Finally, there is an equivalent to the Bastille-Linux hardening scripts for Solaris called TITAN. The TITAN project and documentation can be establish at http://www.fish.com/titan/.

    OpenBSD-Specific Tasks

    This section concentrates on OpenBSD 2.7, which is one of the three more illustrious BSD variants; the others being NetBSD and FreeBSD. Each variant has focused on a different problem: NetBSD is the most portable, FreeBSD has the best performance, and OpenBSD is the most secure.

    One of the powerful strengths of OpenBSD is the highly secure default stance of a default install of OpenBSD. The OpenBSD Web site claims "three years without a remote pocket in the default install, only one localhost pocket in two years in the default install." Almost sum services are disabled until the administrator has enough experience to properly configure them.

    Two additional changes necessary for an OpenBSD box to become a firewall are to disable sendmail and enable IP filter support. Both changes are made to the same file, /etc/rc.conf. To disable sendmail, change

    sendmail_flags="-q30m"

    to

    sendmail_flags=NO

    To enable IP filter support, you must change

    ipfilter=NO

    to

    ipfilter=YES

    Additionally, if you will be doing Network Address Translation (NAT), providing transparent proxying, or providing advocate for FTP, you must enable the ipnat option by setting ipnat=YES. Syntax for IP filters will be covered briefly later in the chapter.


    OpsMgr 2007 R2 hardware, software, security requirements | killexams.com real questions and Pass4sure dumps

    Solutions provider takeaway: remove a spy at information on how to exercise OpsMgr 2007 R2, Get an overview of OpsMgr component requirements and become an expert on advanced OpsMgr concepts and security. Learning about OpsMgr 2007 R2 component requirements, such as hardware and software, will abet solutions providers ensure OpsMgr is functional and reliable. They will also requisite to be alert of advocate for non-Windows devices, capacity limits and how to hold track of the size of the OpsMgr 2007 R2 database.

    Understanding How to exercise OpsMgr

    Using OpsMgr is relatively straightforward. The OpsMgr monitoring environment can be accessed through three sets of consoles: an Operations Console, a Web console, and a command shell. The Operations Console provides plenary monitoring of agent systems and administration of the OpsMgr environment, whereas the Web console provides access only to the monitoring functionality. The command shell provides command-line access to administer the OpsMgr environment.

    Managing and Monitoring with OpsMgr

    As mentioned in the preceding section, two methods are provided to configure and view OpsMgr settings. The first approach is through the Operations Console and the second is through the command shell.

    Within the Administration section of the Operations Console, you can easily configure the security roles, notifications, and configuration settings. Within the Monitoring section of the Operations Console, you can easily monitor a quick "up/down" status, active and closed alerts, and authenticate overall environment health.

    In addition, a web-based monitoring console can be sprint on any system that supports Microsoft Internet Explorer 6.0 or higher. This console can be used to view the health of systems, view and respond to alerts, view events, view performance graphs, sprint tasks, and manage Maintenance mode of monitored objects. unusual to OpsMgr 2007 R2 is the aptitude to panoply the Health Explorer in the Web console.

    Reporting from OpsMgr

    OpsMgr management packs commonly embrace a variety of preconfigured reports to explicate information about the operating system or the specific application they were designed to drudgery with. These reports are sprint in SQL Reporting Services. The reports provide an effectual view of systems and services on the network over a custom period, such as weekly, monthly, or quarterly. They can also abet you monitor your networks based on performance data, which can embrace censorious pattern analysis, trend analysis, capacity planning, and security auditing. Reports also provide availability statistics for distributed applications, servers, and specific components within a server.

    Availability reports are particularly useful for executives, managers, and application owners. These reports can explicate the availability of any object within OpsMgr, including a server (shown in figure 23.5), a database, or even a service such as Windows Server 2008 R2 that includes a multitude of servers and components. The Availability report shown in figure 23.5 indicates that the SP server was down on 9/29/2009 for about 4.17% of the time or just slightly over 1 hour. The relaxation of the time it had been up.

    FIGURE 23.5 Availability report.

    The reports can be sprint on demand or at scheduled times and delivered via email. OpsMgr can also generate HTML-based reports that can be published to a web server and viewed from any web browser. Vendors can also create additional reports as share of their management packs.

    Using Performance Monitoring

    Another key feature of OpsMgr is the capability to monitor and track server performance. OpsMgr can be configured to monitor key performance thresholds through rules that are set to collect predefined performance data, such as reminiscence and CPU usage over time.

    Rules can be configured to trigger alerts and actions when specified performance thresh-olds own been met or exceeded, allowing network administrators to act on potential performance issues. Performance data can be viewed from the OpsMgr Operations Console.

    In addition, performance monitors can establish baselines for the environment and then alert the administrator when the counter subsequently falls outside the defined baseline envelope.

    Using active Directory Integration

    Active Directory integration provides a pass to install management agents on systems without environmental-specific settings. When the agent starts, the remedy environmental settings, such as the primary and failover management servers, are stored in active Directory. The configuration of active Directory integration provides advanced search and filter capabilities to fine-tune the dynamic assignment of systems.

    Integrating OpsMgr Non-Windows Devices

    Network management is not a unusual concept. Simple management of various network nodes has been handled for quite some time through the exercise of the SNMP. Quite often, simple or even complicated systems that utilize SNMP to provide for system monitoring are in region in an organization to provide for varying degrees of system management on a network.

    OpsMgr can be configured to integrate with non-Windows systems through monitoring of syslog information, log file data, and SNMP traps. OpsMgr can also monitor TCP port communication and website transaction sequencing for information-specific data management.

    New to OpsMgr 2007 R2 is the aptitude to monitor non-Microsoft operating systems such as Linux and UNIX, as well as the applications that sprint on them such as Apache and MySQL. OpsMgr monitors the file systems, network interfaces, daemons, configurations, and performance metrics. Operations Manager 2007 R2 supports monitoring of the following operating systems:

  • HP-UX 11i v2 and v3 (PA-RISC and IA64)
  • Sun Solaris 8 and 9 (SPARC) and Solaris 10 (SPARC and x86)
  • Red Hat Enterprise Linux 4 (x86/x64) and 5 (x86/x64) Server
  • Novell SUSE Linux Enterprise Server 9 (x86) and 10 SP1 (x86/x64)
  • IBM AIX v5.3 and v6.1
  • These operating systems are "first-class citizens" in Microsoft's parlance, meaning they are treated as equals with the Windows operating systems. Agents can be pushed from the console, operations data is collected automatically, tasks can sprint against the agents, and sum major functions are supported.

    Special connectors can be created to provide bidirectional information flows to other management products. OpsMgr can monitor SNMP traps from SNMP-supported devices as well as generate SNMP traps to be delivered to third-party network management infrastructures.

    Exploring Third-Party Management Packs

    Software and hardware developers can subsequently create their own management packs to extend OpsMgr's management capabilities. These management packs extend OpsMgr's management capabilities beyond Microsoft-specific applications. Each management pack is designed to accommodate a set of rules and product lore required to advocate its respective products. Currently, management packs own been developed for APC, Cisco, Citrix, Dell, F5, HP, IBM, Linux, Oracle, Solaris, UNIX, and VMware to designation a few. A complete list of management packs can be establish at the following Microsoft site: http://technet. microsoft.com/en-us/opsmgr/cc539535.aspx.

    Understanding OpsMgr Component Requirements

    Each OpsMgr component has specific design requirements, and a fine lore of these factors is required before beginning the design of OpsMgr. Hardware and software requirements must be taken into account, as well as factors involving specific OpsMgr components, such as the Root Management Server, gateway servers, service accounts, mutual authentication, and backup requirements.

    Exploring Hardware Requirements

    Having the proper hardware for OpsMgr to operate on is a censorious component of OpsMgr functionality, reliability, and overall performance. Nothing is worse than overloading a brand-new server only a few short months after its implementation. The industry touchstone generally holds that any production servers deployed should remain germane for three to four years following deployment. Stretching beyond this time frame might be possible, but the horrible truth is that hardware investments are typically short term and requisite to be replaced often to ensure relevance. Buying a less-expensive server might reclaim money in the short term but could potentially expand costs associated with downtime, troubleshooting, and administration. That said, the following are the Microsoft-recommended minimums for any server running an OpsMgr 2007 server component:

  • 2.8GHz processor or faster
  • 20GB of free disk space
  • 2GB of random access reminiscence (RAM)
  • These recommendations apply only to the smallest OpsMgr deployments and should be seen as minimum levels for OpsMgr hardware. More realistic deployments would own the following minimums:

  • 2--4 2.8GHz cores
  • 64-bit Windows operating system
  • 64-bit SQL Server
  • 60GB free disk space on RAID 1+0 for performance
  • 4--8GB RAM
  • Operations Manager 2007 R2 is one of Microsoft's most resource-intensive applications, so generous processor, disk, and reminiscence are significant for optimal performance. Future expansion and relevance of hardware should be taken into account when sizing servers for OpsMgr deployment, to ensure that the system has margin to grow as agents are added and the databases grow.

    Determining Software Requirements

    OpsMgr components can be installed on either 32-bit or 64-bit versions of Windows Server 2003, Windows Server 2008, or Windows Server 2008 R2. The database for OpsMgr must be sprint on a Microsoft SQL Server 2005 or Microsoft SQL Server 2008 server. The database can be installed on the same server as OpsMgr or on a divorce server, a concept that is discussed in more detail in following sections.

    OpsMgr itself must be installed on a member server in a Windows active Directory domain. It is commonly recommended to hold the installation of OpsMgr on a divorce server or set of dedicated member servers that carry out not sprint any other applications that could interfere in the monitoring and alerting process.

    A few other requirements censorious to the success of OpsMgr implementations are as follows:

  • Microsoft .NET Framework 2.0 and 3.0 must be installed on the management server and the reporting server.
  • Windows PowerShell.
  • Microsoft Core XML Services (MSXML) 6.0.
  • WS-MAN v1.1 (for UNIX/Linux clients).
  • Client certificates must be installed in environments to facilitate mutual authentication between nondomain members and management servers.
  • SQL Reporting Services must be installed for an organization to be able to view and defer custom reports using OpsMgr's reporting feature.
  • OpsMgr Backup Considerations

    The most censorious piece of OpsMgr, the SQL databases, should be regularly backed up using touchstone backup software that can effectively achieve online backups of SQL databases. If integrating these specialized backup utilities into an OpsMgr deployment is not possible, it becomes necessary to leverage built-in backup functionality establish in SQL Server.

    Understanding Advanced OpsMgr Concepts

    OpsMgr's simple installation and relative ease of exercise often belie the potential complexity of its underlying components. This complexity can be managed with the privilege amount of lore of some of the advanced concepts of OpsMgr design and implementation.

    Understanding OpsMgr Deployment Scenarios

    As previously mentioned, OpsMgr components can be divided across multiple servers to ration load and ensure balanced functionality. This separation allows OpsMgr servers to approach in four potential "flavors," depending on the OpsMgr components held by those servers. The four OpsMgr server types are as follows:

  • Operations database server -- An operations database server is simply a member server with SQL Server installed for the OpsMgr operations database. No other OpsMgr components are installed on this server. The SQL Server component can be installed with default options and with the system account used for authentication. Data in this database is kept for 7 days by default.
  • Reporting database server -- A reporting database server is simply a member server with SQL Server and SQL Server Reporting Services installed. This database stores data collected through the monitoring rules for a much longer term than the operations database and is used for reporting and trend analysis. This database requires significantly more drive space than the operations database server. Data in this data-base is kept for 13 months by default.
  • Management server -- A management server is the communication point for both management consoles and agents. Effectively, a management server does not own a database and is often used in large OpsMgr implementations that own a dedicated database server. Often, in these configurations, multiple management servers are used in a separate management group to provide for scalability and to address multiple managed nodes.
  • All-in-one server -- An all-in-one server is effectively an OpsMgr server that holds sum OpsMgr roles, including that of the databases. Subsequently, single-server OpsMgr configurations exercise one server for sum OpsMgr operations.
  • Multiple Configuration Groups

    As previously defined, an OpsMgr management group is a logical grouping of monitored servers that are managed by a separate OpsMgr SQL database, one or more management servers, and a unique management group name. Each management group established operates completely separately from other management groups, although they can be configured in a hierarchical structure with a top-level management group able to observe "connected" lower-level management groups.

    The concept of connected management groups allows OpsMgr to scale beyond synthetic boundaries and also gives a powerful deal of flexibility when combining OpsMgr environments. However, certain caveats must be taken into account. Because each management group is an island in itself, each must subsequently be manually configured with individual settings. In environments with a large number of customized rules, for example, such manual configuration would create a powerful deal of redundant drudgery in the creation, administration, and troubleshooting of multiple management groups.

    Deploying Geographic-Based Configuration Groups

    Based on the factors outlined in the preceding section, it is preferable to deploy OpsMgr in a separate management group. However, in some situations, an organization needs to divide its OpsMgr environment into multiple management groups. The most common reason for division of OpsMgr management groups is division along geographic lines. In situations in which wide zone network (WAN) links are saturated or unreliable, it might be prudent to divorce large "islands" of WAN connectivity into divorce management groups.

    Simply being separated across behind WAN links is not enough reason to warrant a divorce management group, however. For example, diminutive sites with few servers would not warrant the creation of a divorce OpsMgr management group, with the associated hardware, soft-ware, and administrative costs. However, if many servers exist in a distributed, generally well-connected geographical area, that might be a case for the creation of a management group. For example, an organization could be divided into several sites across the United States but resolve to divide the OpsMgr environment into divorce management groups for East Coast and West Coast, to roughly approximate their WAN infrastructure.

    Smaller sites that are not well connected but are not large enough to warrant their own management group should own their event monitoring throttled to avoid being sent across the WAN during peak usage times. The downside to this approach, however, is that the reaction time to censorious event response is increased.

    Deploying Political or Security-Based Configuration Groups

    The less-common manner of dividing OpsMgr management groups is by political or security lines. For example, it might become necessary to divorce financial servers into a divorce management group to maintain the security of the finance environment and allow for a divorce set of administrators.

    Politically, if administration is not centralized within an organization, management groups can be established to divorce OpsMgr management into divorce spheres of control. This would hold each OpsMgr management zone under divorce security models.

    As previously mentioned, a separate management group is the most efficient OpsMgr environment and provides for the least amount of redundant setup, administration, and troubleshooting work. Consequently, synthetic OpsMgr division along political or security lines should be avoided, if possible.

    Sizing the OpsMgr Database

    Depending on several factors, such as the sort of data collected, the length of time that collected data will be kept, or the amount of database grooming that is scheduled, the size of the OpsMgr database will grow or shrink accordingly. It is significant to monitor the size of the database to ensure that it does not expand well beyond the bounds of accept-able size. OpsMgr can be configured to monitor itself, supplying forward notice of data-base problems and capacity thresholds. This sort of strategy is highly recommended because OpsMgr could easily collect event information faster than it could Get rid of it.

    The size of the operations database can be estimated through the following formula:

    Number of agents x 5MB x retention days + 1024 overhead = estimated database size

    For example, an OpsMgr environment monitoring 1,000 servers with the default 7-day retention term will own an estimated 35GB operations database:

    (1000 * 5 * 7) + 1024 = 36024 MB

    The size of the reporting database can be estimated through the following formula:

    Number of agents x 3MB x retention days + 1024 overhead = estimated database size

    The same environment monitoring 1,000 servers with the default 400-day retention term will own an estimated 1.1TB reporting database:

    (1000 * 3 * 400) + 1024 = 1201024 MB

    It is significant to understand that these estimates are jagged guidelines only and can vary widely depending on the types of servers monitored, the monitoring configuration, the degree of customization, and other factors.

    Defining Capacity Limits

    As with any system, OpsMgr includes some difficult limits that should be taken into account before deployment begins. Surpassing these limits could be reason for the creation of unusual management groups and should subsequently be included in a design plan. These limits are as follows:

  • Operations database -- OpsMgr operates through a principle of centralized, rather than distributed, collection of data. sum event logs, performance counters, and alerts are sent to a single, centralized database, and there can subsequently be only a separate operations database per management group. Considering the exercise of a backup and high-availability strategy for the OpsMgr database is, therefore, highly recommended, to protect it from outage. It is recommended to hold this database with a 50GB confine to improve efficiency and reduce alert latency.
  • Management servers -- OpsMgr does not own a hard-coded confine of management servers per management group. However, it is recommended to hold the environment between three to five management servers. Each management server can advocate approximately 2,000 managed agents.
  • Gateway servers -- OpsMgr does not own a hard-coded confine of gateway servers per management group. However, it is recommended to deploy a gateway server for every 200 nontrusted domain members.
  • Agents -- Each management server can theoretically advocate up to 2,000 monitored agents. In most configurations, however, it is prudent to confine the number of agents per management server, although the levels can be scaled upward with more robust hardware, if necessary.
  • Administrative consoles -- OpsMgr does not confine the number of instances of the Web and Operations Console; however, going beyond the suggested confine might interlard performance and scalability problems.
  • Defining System Redundancy

    In addition to the scalability built in to OpsMgr, redundancy is built in to the components of the environment. Proper lore of how to deploy OpsMgr redundancy and region OpsMgr components correctly is significant to the understanding of OpsMgr redundancy. The main components of OpsMgr can be made redundant through the following methods:

  • Management servers -- Management servers are automatically redundant and agents will failover and failback automatically between them. Simply install addi-tional management servers for redundancy. In addition, the RMS system acts as a management server and participates in the frailty tolerance.
  • SQL databases -- The SQL database servers hosting the databases can be made redundant using SQL clustering, which is based on Windows clustering. This supports failover and failback.
  • Root Management Server -- The RMS can be made redundant using Windows clus-tering. This supports failover and failback.
  • Having multiple management servers deployed across a management group allows an environment to achieve a certain even of redundancy. If a separate management server expe-riences downtime, another management server within the management group will remove over the responsibilities for the monitored servers in the environment. For this reason, it might be prudent to embrace multiple management servers in an environment to achieve a certain even of redundancy if high uptime is a priority.

    The first management server in the management group is called the Root Management Server. Only one Root Management Server can exist in a management group and it hosts the software evolution kit (SDK) and Configuration service. sum OpsMgr consoles communicate with the management server so its availability is critical. In large-scale envi-ronments, the Root Management Server should leverage Microsoft Cluster technology to provide high availability for this component.

    Because there can be only a separate OpsMgr database per management group, the database is subsequently a separate point of failure and should be protected from downtime. Utilizing Windows Server 2008 R2 clustering or third-party fault-tolerance solutions for SQL data-bases helps to mitigate the risk involved with the OpsMgr database.

    Monitoring Nondomain Member Considerations

    DMZ, Workgroup, and Nontrusted Domain Agents require special configuration; in partic-ular, they require certificates to establish mutual authentication. Operations Manager 2007 R2 requires mutual authentication, that is, the server authenticates to the client and the client authenticates to the server, to ensure that the monitoring communications are not hacked. Without mutual authentication, it is feasible for a hacker to execute a man-in-the-middle assail and impersonate either the client or the server. Thus, mutual authenti-cation is a security measure designed to protect clients, servers, and sensitive active Directory domain information, which is exposed to potential hacking attempts by the all-powerful management infrastructure. However, OpsMgr relies on active Directory Kerberos for mutual authentication, which is not available to nondomain members.

    Note:Workgroup servers, public web servers, and Microsoft Exchange Edge Transport role servers are commonly placed in the DMZ and are for security reasons not domain members, so almost every Windows Server 2008 R2 environment will requisite to deploy certificate-based authentication.

    In the absence of active Directory, trusts, and Kerberos, OpsMgr 2007 R2 can exercise X.509 certificates to establish the mutual authentication. These can be issued by any PKI, such as Microsoft Windows Server 2008 Enterprise CA. observe Chapter 14, "Transport-Level Security," for details on PKI and Windows Server 2008 R2.

    Installing agents on DMZ servers is discussed later in this chapter in the section "Monitoring DMZ Servers with Certificates."

    Securing OpsMgr

    Security has evolved into a primary concern that can no longer be taken for granted. The inherent security in Windows Server 2008 R2 is only as fine as the services that own access to it; therefore, it is prudent to achieve a security audit of sum systems that access information from servers. This concept holds genuine for management systems as well because they collect sensitive information from every server in an enterprise. This includes potentially sensitive event logs that could be used to compromise a system. Consequently, securing the OpsMgr infrastructure should not be taken lightly.

    Securing OpsMgr Agents

    Each server that contains an OpsMgr agent and forwards events to management servers has specific security requirements. Server-level security should be established and should embrace provisions for OpsMgr data collection. sum traffic between OpsMgr components, such as the agents, management servers, and database, is encrypted automatically for security, so the traffic is inherently secured.

    In addition, environments with high-security requirements should investigate the exercise of encryption technologies such as IPSec to scramble the event IDs that are sent between agents and OpsMgr servers, to protect against eavesdropping of OpsMgr packets.

    OpsMgr uses mutual authentication between agents and management servers. This means that the agent must reside in the same forest as the management server. If the agent is located in a different forest or workgroup, client certificates can be used to establish mutual authentication. If an entire nontrusted domain must be monitored, the gateway server can be installed in the nontrusted domain, agents can establish mutual authentication to the gateway server, and certificates on the gateway and management server are used to establish mutual authentication. In this scenario, you can avoid needing to region a certificate on each nontrusted domain member.

    Understanding Firewall Requirements

    OpsMgr servers that are deployed across a firewall own special considerations that must be taken into account. Port 5723, the default port for OpsMgr communications, must specifically be opened on a firewall to allow OpsMgr to communicate across it.

    Table 23.1 describes communication for this and other OpsMgr components.

    TABLE 23.1 OpsMgr Communication Ports

    From To Port Agent Root Management Server 5723 Agent Management Server 5723 Agent Gateway Server 5723 Agent (ACS forwarder) Management server ACS collector 51909 Gateway Server Root Management Server 5723 Gateway Server Root Management Server 5723 Management or Gateway server Unix or Linux computer 1270 Management or Gateway server Unix or Linux computer 22 Management server Operations Manager database 1433 Management server Root Management Server 5723, 5724 Management server Reporting data warehouse 1433 Management server ACS collector ACS database 1433 Operations console Root Management Server 5724 Operations console (reports) SQL Server reporting services 80 Reporting server Root Management Server 5723, 5724 Reporting server Reporting data warehouse 1433 Root Management Server Operations Manager database 1433 Root Management Server Reporting data warehouse 1433 Web console browser Web console server 51908 Web console server Root Management Server 5724

    The firewall port for the agents is the port that needs to be opened most often, which is only port 5723 from the agent to the management servers for monitoring. Other ports, such as 51909 for ACS, are more rarely needed. figure 23.6 shows the major communications paths and ports between OpsMgr components.

    FIGURE 23.6 Communications ports.

    Outlining Service Account Security

    In addition to the aforementioned security measures, security of an OpsMgr environment can be strengthened by the addition of multiple service accounts to wield the different OpsMgr components. For example, the Management Server Action account and the SDK/Configuration service account should be configured to exercise divorce credentials, to provide for an extra layer of protection in the event that one account is compromised.

  • Management Server Action account -- The account accountable for collecting data and running responses from management servers.
  • SDK and Configuration service account -- The account that writes data to the operations database; this service is also used for sum console communication.
  • Local Administrator account -- The account used during the agent shove installation process. To install the agent, local administrative rights are required.
  • Agent Action account -- The credentials the agent will sprint as. This account can sprint under a built-in system account, such as Local System, or a limited domain user account for high-security environments.
  • Data Warehouse Write Action account -- The account used by the management server to write data to the reporting data warehouse.
  • Data Warehouse Reader account -- The account used to read data from the data warehouse when reports are executed.
  • Run As accounts -- The specific accounts used by management packs to facilitate monitoring. These accounts must be manually created and delegated specific rights as defined in the management pack documentation. These accounts are then assigned as sprint As accounts used by the management pack to achieve a high degree of security and flexibility when monitoring the environment. unusual to OpsMgr 2007 R2 is the aptitude to selectively ration the sprint As Account to just the agents that requisite them.

    We're quiet looking for input for the final version of this page, which will be share of the January 7, 1999 issue of LWN. gratify drop us a note with your suggestions for additions to this page.

    This page was produced by Jonathan Corbet at Eklektix, Inc. Contributions own since approach in from Zachary Beane, Christopher Bohn, designate Bolzern, Malcolm Caldwell, Victor Chang, Alan Cox, David Damerell, Joe DeVita, Gael Duval, Sammy Ford, Emmanuel Galanos, Jason Haas, Hans ?

Wheeler, Micah Yoder, and James Youngman. Many thanks to sum of these folks!

    You may jump straight to the month of your choice: January, February, March, April, May, June, July, August, September, October, November, or December.

    The Linux Weekly advice begins publication. The very first issue, dated January 22, was a just a tiny hint of what LWN was to become. Since then we've gotten better at it, and the Linux world has gotten much more complicated. It has been an keen adventure.

    [Netscape]Netscape announces that they will release the source to their browser under a free software license. This almost certainly remains one of the most significant events of the year; it opened a lot of eyes to what Linux and free software could provide.

    [RHAD] Red Hat Advanced evolution Labs is founded. It has since become one of the higher-profile places where people are paid to develop free software, and an significant component of the GNOME project. RHAD is able to attract developers like "Rasterman" and Federico Mena Quintero.

    The Stampede Linux distribution is announced. Actually, this happened in December, but the advice took a while to spread... Stampede positions itself as a high-performance "real Linux hacker's" distribution.

    Word gets out that parts of the blockbuster film "Titanic" were rendered on Alpha machines running Linux. This was another significant step in the "legitimization" of Linux - everybody had heard of The Titanic, and some of its success seemed to rub off on everything associated with it.

    [Qube] The Cobalt Qube is announced and immediately becomes a favorite in the trade press due to its high performance, low price, and cute profile factor. Cobalt's Linux engineering is done by not one other than David Miller, source of much that is fine in the Linux kernel.

    [prize] The Linux user community wins InfoWorld's technical advocate award; Red Hat 5.0 also won their Operating System award. But it was the tech advocate award that truly opened some eyes; everybody had been adage that Linux had no support. This was the beginning of the terminate of the "no support" argument.

    [opensource] Red Hat announces that their installation advocate staff is running behind. They are a victim of their own success, and examine for resignation while they Get their act together.

    Linux according to Jesse Berst "I mediate it's powerful if you are willing to promote Linux to your boss. As long as you are alert of the risk you are taking. The risk of getting fired." (Feb. 16). "Is a Linux takeover likely? Give me a break. Of course not." (June 23). "I personally mediate Windows NT will be the mainstream operating system within a few years." [...] "My belief: Linux will never proceed mainstream" (Sep. 9). "I've always said that Linux could become a serious challenger to Microsoft's Windows NT." Sep. 28).

    Eric Raymond and friends approach up with the "open source" term. They apply for trademark status, and attach up the opensource.org web site. Thus begins the formal distress to shove Linux for corporate use.

    Linus Torvalds and Richard Stallman win the EFF Pioneer award. The award recognizes their contributions to electronic freedom. Strangely, sum mention of this seems to own vanished from the Electronic Frontier Foundation web site.

    Caldera 1.2 is released. Unlike Red Hat, which had been shipping libc6 based systems for some time, Caldera sticks with the tried and genuine libc5.

    The OpenBIOS project is launched, in the faith that no system is free if it depends on proprietary BIOS code. A web page is set up for the project.

    [GGI] Major battles rage over whether GGI belongs in the Linux Kernel. GGI, the "Generic Graphics Interface," seeks to defer a better defined, better supported interface to video cards on Linux and other systems. Interestingly, GGI had made no request for kernel inclusion at this time. No resolution was reached, but better communications with a number of kernel hackers did result from this episode.

    The Linux common Store opens; this is "the first walk-in Linux store." (Web page here).

    [Learning tree] Learning Tree, International adds a Linux administration course to their lineup. This course is offered frequently in the U.S. and Britain. "The trait of Linux software has improved dramatically, making it a low-cost, reliable, supported computing platform appropriate for the commerce environment."

    Consumer advocate Ralph Nader asks the large PC vendors (Dell, Gateway, Micron...) to offer non-Microsoft systems, including systems with Linux installed. (See InfoPolicy Notes).

    Sun offers 70% discounts for people interested in "upgrading" from Linux to Solaris.

    [Debian] [Sendmail logo] Bruce Perens, once leader of the Debian project, quits entirely in the wake of disagreements on how the project should proceed.

    Sendmail, Inc. is formed by Eric Allman, in an attempt to win money selling sendmail advocate services while keeping the basic sendmail code free.

    John Kirch releases his "Microsoft Windows NT Server 4.0 versus Unix" paper. This paper remains one of the best advocacy pieces out there, and should be required reading for anybody contemplating deployment of either technology.

    [Mozilla] The Mozilla source code hits the net. Netscape throws a huge party. The code is downloaded sum over the world, and people start hacking. unusual features, such as stalwart encryption and a Qt port, are added almost immediately.

    Linus makes Inter@ctive Week's "25 Unsung Heroes of the Net" list. He is in fine company, joining names like Steven Bellovin, Van Jacobson, Peter G. Neumann, and others. April was maybe about the eventual time that Linus could be said to be an "unsung" hero.

    Linus announces Linux 2.1.92 and declares a 2.1 feature freeze. The announcment goes as far as to jabber "...there are probably quiet bugs with some of the unusual code, but I'll freeze unusual features for the upcoming 2.2 kernel." This freeze turned out to be rather slushy, to jabber the least.

    The Open Group announces a unusual licensing policy for the X window system. unusual versions of X will be proprietary and only available to paying customers. They immediately withhold some security bugfixes from common distribution. XFree86 decides that it can not live with the unusual licensing, and declares its intent to proceed its own way.

    [NPR] Linux is covered by the U.S. National Public Radio news, marking one of its first appearances in the mainstream, non-technical press.

    O'Reilly holds the "first ever" Free Software Summit, featuring Larry Wall, Brian Behlendorf, Linus Torvalds, Guido van Rossum, Eric Allman, Phil Zimmermann, Eric Raymond, and Paul Vixie.

    The Linux Weekly advice daily updates page debuts. Despite LWN's intent to hold the its weekly focus, the daily page eventually exceeds the weekly newsletter in traffic. The Linux events calendar is also announced.

    Linus 3.0 is announced; the birth of Linus's second daughter causes powerful joy, and substantial disruption in kernel evolution as sum drudgery stops and many patches Get lost. Some grumbling results as it becomes clear just how relative the entire process is on Linus's constant presence.

    RH  advocate  ally logo[Avalon] Red Hat announces their commercial advocate program, based on a worldwide network of "support partners," of which Eklektix, Inc., the producer of the Linux Weekly News, is one.

    The Avalon Beowulf cluster at Los Alamos goes on line and immediately powers itself into the list of the fastest computers on the planet.

    Eric S. Raymond publishes "Homesteading the Noosphere" on the web; This paper gives his view of how economics of open source software can work.

    Kernel hacker Alan Cox goes to drudgery for Red Hat.

    Bruce Perens proposes a unusual Linux distribution (proposal here) based on his experience with Debian. This distribution never comes about, but much of what's there later gets folded into the Linux touchstone ground project.

    [Project Heresy C|Net's "Project Heresy" starts a high-profile attempt to drudgery using only Linux. The result was a long series of articles and "radio" programs, sum on the Project Heresy page.

    Sun Microsystems joins Linux International.

    [Google] The "Google" search engine pops up. Not only is it one of the best search engines around, but it's based on Linux and features a Linux-specific search page.

    Sm@rt Reseller reports that Oracle and Informix own no plans to advocate Linux. "In fact, many doubt that Linux-no matter how stable or how cheap-can ever compete in the corporate marketplace alongside the well-funded Windows NT and Solaris." (article here).

    [SuSE] The SuSE 5.2 distribution is released.

    [Corel] Corel formally embraces Linux. The Netwinder products are featured, and they pledge their advocate for the Linux system.

    The Association Francophone des Utilsateurs de Linux et des Logiciels Libres (AFUL) is formed in France. AFUL promptly becomes a compel in French computer circles.

    O2 large databases start to arrive. advocate for Linux is announced by Computer Associates for their Ingres system, and by Ardent Software for their O2 object database.

    The Linux Core/Layers project was announced and became the first in a series of attempts at creating standards for Linux systems. The Core/Layers page quiet exists, but this project is no longer active in this form.

    "But Linux is a communist operating system in a capitalist society. Its popularity is going to lead toward its fragmentation....The large problem with Linux is that it has no discrete direction. It's in the privilege region at the privilege time, but its 15 minutes are nearly up." (PC Week, May 22).

    The Linux Weekly advice moved to its own domain at lwn.net.

    A proposal goes out to create the Linux touchstone ground (LSB) project. This proposal, signed by a large number of Linux luminaries, was discussed at Linux Expo and formed into a project, with Bruce Perens at the head. Numerous editorials were written and posted on FreshMeat; the list can be establish on the LSB web page. The LSB then disappeared from view for a few months.

    And, yes, Linux Expo was held; a fine time was had by all.

    Red Hat 5.1 was released and immediately started accumulating rather more than the customary number of updates (partly as a result of the Linux Security Audit program). There was talk of "Red Hat 5.1 service pack 1" as a result. 5.1 did eventually stabilize into a solid release.

    "First, let me jabber that I am uniquely unqualified to write about this week's topic. like most of you, I've never used Linux....Linux has a snowball's desultory in hell of making perceptible inroads against Windows." (The infamous John Dodge hatchet job, PC Week, June 8).

    The Open Group offers the possibility of Unix 98 certification to Linux at the Uniforum meeting. The resulting press release says "Since the Linux OS is proving to be increasingly inelastic competition for NT in this marketspace, it's in the best interest of sum Unix vendors for Linux to Get branded so that it may compete more effectively and hold the low terminate UNIX 98-compliant." Very microscopic is heard thereafter.

    The Gartner Group says there is microscopic hope for free software. "...these operating systems will not find widespread exercise in mainstream commercial applications in the next three years, nor will there be broad third-party application support."

    [Wilbur] The Gimp 1.0 is released. This long-awaited release of one of Linux's highest profile tools did not disappoint.

    Stable kernel 2.0.34 is released after a long prepatch series.

    [Beowulf] The Beowulf web site shuts down temporarily due to concerns about U.S. export restrictions. Suddenly anybody can create a supercomputer, and people are getting worried. observe this Dr. Dobbs article for some more background. Shortly thereafter the site (www.beowulf.org) is back up as if nothing had happened.

    The Datapro study comes out showing that Linux has the highest user satisfaction of any system; it also shows Linux to be the only system other than NT that is increasing market share.

    "Like a lot of products that are free, you Get a loyal following even though it's small. I've never had a customer mention Linux to me." (Bill Gates in PC Week, June 25).

    [Netwinder] Corel launches the Netwinder DM with this press release.

    Debian 2.0 goes into beta test after numerous delays.

    [Adaptec] Adaptec reverses its longstanding nondisclosure policy and announces advocate for Linux. The initial deal was with Red Hat; other distribution vendors own since then announced agreements with Adaptec.

    The Chinese Linux Extension project begins; this project is doing a Chinese localization of Linux. (Web page (mix English/Chinese) here).

    IBM announces that it will ration and advocate the Apache web server, after working a deal with the Apache team.

    [Rocket]

    The Silicon Valley Linux Users Group holds "The powerful Linux Revolt of 1998", turning Microsoft's Windows 98 product launch celebration into a Linux publicity event at two high-profile retail outlets.

    Not content with that, The Silicon Valley Linux Users Group Launches Windows 98...on a rocket.

    The UK Linux Developers' Conference is held in Manchester (basic web page here).

    Rumors of a merger between Caldera and Red Hat circulate. It hasn't happened yet...

    The desktop wars rage as KDE and GNOME advocates hurl flames at each other. Linus gets in on the act, adage that KDE is OK with him. Those who are feeling nostalgic can head over to this Slashdot discussion just to observe how much fun it really was.

    In this context, KDE 1.0 is released. The first stable release of the K Desktop Environment proves popular, despite the complaints from those who carry out not like the licensing of the Qt library.

    NC World magazine shuts down with Nicholas Petreley's devastating criticism of Windows NT. The article, (still available on the net), concludes that Windows NT 5 (now "Windows 2000") can only be an absolute disaster.

    Stable kernel 2.0.35 is released.

    The Internet Operating System Counter goes online and finds, after querying hundreds of thousands of hosts, that Linux has the largest web server market share of any operating system out there. The results are available on the Internet Operating System Counter page.

    LinuxPPC 4.0 is released.

    "IBM, Informix, and Sybase also own no intentions of releasing versions of their databases on Linux, company representatives said." (InfoWorld, July 6)

    [Oracle] Oracle announces advocate for Linux in this press release. They swear to win a affliction version available by the terminate of 1998, a deadline they beat by months. This, seemingly, was one of the acid tests for the potential of long-term success for Linux; a powerful deal of attention resulted from this announcement.

    [Informix] Informix announces advocate for Linux on almost the same day with a press release of their own.

    The SVLUG/Taos "Future of Linux" panel is held featuring Linus and numerous other luminaries. (Writeup here). Among other things, this conference is where Intel first started making serious noises about supporting Linux.

    "When I heard that Steve Ballmer was promoted to the office of president at Microsoft, I couldn't abet but prodigy if he was being set up to remove the descend when Windows NT 5.0 proves to be a catastrophic market failure and Linux supplants Windows NT as the future server operating system of choice."(Nicholas Petreley, InfoWorld, July 27).

    [Forbes cover] Linus appears on the cover of Forbes magazine. A lengthy legend presents Linux in a highly positive manner, and brings the system to the attention of many who had never heard of it before. Linux begins to become a household word. (Yes, it was the August 10 issue, but it came out in July).

    The first release of the Mandrake distribution is announced. Mandrake is a version of the Red Hat distribution with international language advocate and KDE added.

    Stampede distribution 0.86 is released.

    Debian 2.0 is released with this announcement. It is a huge distribution, containing over 1500 packages and requiring at least two CD's to hold it.

    MkLinux distribution DR3 is released, announced thusly.

    Caldera releases Netware for Linux 1.0 (product info here).

    The EiffelBase library is released under an open source license; this library had previously been proprietary. (Info here).

    Red Hat announces (again) that their installation advocate staff is running behind (again). Their note on the topic asks for resignation while they Get their act together.
