[2004-02-24] Python in Systems Administration: Part I -- Better Scripting
One well-honed item in every sys admin's toolbox is a preferred scripting language -- maybe sh, or ksh, or Perl, or something more unusual, like Rexx or Ruby. I find Python so capable and easy to learn that in my consulting role at Phaseit, I tell newcomers it's the best single language they can learn. Python spans a wider range of applications than any other language I know -- even more than C or Java -- and beginners pick it up quickly.
[2004-02-23] Neglect and Misunderstanding of Backups
I had a call this week from a client who needed a file restored from backup. I had set them up with DVD-RAM and a Supertar a year ago, and had labeled five cartridges with Mon, Tues, etc. I know that (or thought I knew) they followed this rotation for a while, because I had used the previous day's backup to restore files for them earlier this year.
[2004-02-19] Performance Optimizing Syslog Server
We are quite often asked how many syslog message per second MonitorWare Agent can receive. The answer is not as simple as it may look. It largely depends. So I finally thought I write this brief article on the factors that influence syslog server performance. Obviously, you can also use it as a rough guide to optimizing your setup.
[2004-02-17] Kerio Mail Server
The Kerio Mail Server is a cross platform ( Windows, Linux, and Mac OSX) mail server. I tested it on RedHat Linux 8.
[2004-02-10] Penetration Test : My Meanest Hack
I was requested to perform a proof of concept hack into a large organization a few weeks ago. The aim was to get an interactive session, preferably GUI, on one of the internal machines which was guarded by 2 (External and DMZ) firewalls, and an Intrusion detection system. I was allowed to use any means necessary to achieve this goal. This is extremely unusual for a penetrations test, where the rules, guidelines and penetration methods are very strict and defined. I was supposed to impersonate a hacker that would stop at nothing to gain interactive access to the internal network.
