		<title><![CDATA[System Administration Toolkit: Distributed administration using SSH]]></title> 
		<description><![CDATA[Use Secure Shell (SSH) to run commands on remote UNIX(R) systems and, with
      some simple scripts, put together a system that enables you to manage many systems
      simultaneously from one machine without having to log in directly to the machines
      themselves. Also examine the basics of a distributed management system and some
      scripts and solutions using the technique.]]></description>

		<description><![CDATA[Examine methods for standardizing your interface to simplify movements between different UNIX(R) systems. If you manage multiple UNIX systems, particularly in a heterogeneous environment, then the hardest task can be switching between the different environments and performing the different tasks while having to consider all of the differences between the systems. This article does not cover specific differences, but you&apos;ll look at ways that can provide compatible layers, or wrappers, to support a consistent environment.]]></description>

		<title><![CDATA[System Administration Toolkit: Migrating and moving UNIX directory trees]]></title> 
		<description><![CDATA[Occasionally, you need to copy around an entire UNIX(R) directory tree, either between areas on the same system or between different systems. There are many different methods of achieving this, but not all preserve the right amount of information or are compatible across different systems. This article discusses the various options available for UNIX and how best to make them work.]]></description>

		<title><![CDATA[System Administration Toolkit: Migrating and moving UNIX filesystems]]></title> 
		<description><![CDATA[Learn how to transfer an entire file system on a live system, including how to create, copy, and re-enable the new file system. If you have a UNIX(R) disk or system failure or simply fill up your file system, then you need to create a new partition and file system and copy over the contents. You might even need to mount the new partition in place to preserve the location of vital files and components. To add further complications, you need to do this on a live system, where you&apos;d need to preserve file permissions, ownership, and possibly named pipes and other components. Effectively transferring these components and retaining all of this information is a vital part of the migration process.]]></description>

		<title><![CDATA[System Administration Toolkit: Process administration tricks]]></title> 
		<description><![CDATA[Discover how to get the information you want on UNIX(R) processes. Knowing what is running on your UNIX system is one of the most basic requirements of any system administrator. The standard process list is useful, but often the information that it provides is not in the right format or doesn&apos;t contain exactly the processes or information you need. In this article, you&apos;ll examine how to extend that process further to improve the readability of the information, or provide summaries and information that are not easily obtainable elsewhere. You&apos;ll also look at methods for standardizing how to obtain process information across different UNIX platforms.]]></description>

		<title><![CDATA[Systems Administration Toolkit: Using SNMP data]]></title> 
		<description><![CDATA[The Simple Network Management Protocol (SNMP) is built in to many devices, but
   often the tools and software that can read and parse this information are too large and
   complicated when you only want to check a quick statistic or track a particular device
   or issue. This article looks at some simplified methods for getting SNMP information
   from your devices and how to integrate this information into the rest of your network&apos;s data map.]]></description>

		<description><![CDATA[Discover how to scan your network for services and how to regularly monitor
      your services to keep uptimes to a maximum. A key way of ensuring the security of
      your network is to know what is on your network and what services individual
      machines are at risk of exposure. Unauthorized services, such as Web servers or file
      sharing solutions, not only degrade performance, but others can use these services
      as routes into your network. In this article, learn how to use these same techniques
      to ensure that genuine services remain available.]]></description>

		<description><![CDATA[Look at how to create scripts that are able to record their output, trap and
      identify errors, and recover from errors and problems so that they either run
      correctly or fail with a suitable error message and report. Building scripts and
      running them automatically is a task that every good administrator has to handle,
      but how do you handle the error output and make intelligent decisions about how the
      script should handle these errors? This article addresses these issues.]]></description>
