The roll of the System Administrator on a linux or unix like system involves a number of varied and complicated tasks. A defined and well thought out approach to these tasks is the key to running efficient and reliable systems. The following is a small list of some of the important duties of the System Administrator. Filesystem Integrity and Free Space: A breakdown in filesystem integrity means the potential loss of critical data. As such, the System Administrator must check filesystem integrity on a regular basis and repair any inconsistencies as soon as they are found. The availability of free space is also the concern of the System Administrator. Periodic checking, daily, hourly, or as required is essential in preventing a file system from filling completely and causing downtime. Configuration Files: Many configuration files will require modification over the lifetime of an installed system. The System Administrator must document all changes and maintain backup copies of previous...

Active FTP vs. Passive FTP Introduction One of the most commonly seen questions when dealing with firewalls and other Internet connectivity issues is the difference between active and passive FTP and how best to support either or both of them. Hopefully the following text will help to clear up some of the confusion over how to support FTP in a firewalled environment. This may not be the definitive explanation, as the title claims, however, I've heard enough good feedback and seen this document linked in enough places to know that quite a few people have found it to be useful. I am always looking for ways to improve things though, and if you find something that is not quite clear or needs more explanation, please let me know! Recent additions to this document include the examples of both active and passive command line FTP sessions. These session examples should help make things a bit clearer. They also provide a nice picture into what goes on behind the sc...
