Well I finally got a chance to look at the SANS Institute handbook "Securing Linux Step-by-Step" and from what I have seen, so far, is very good information. In a nutshell it covers the installation, securing a workstation, securing a server, tuning and packet firewalls and a bunch of tools. It goes into depth with Sendmail, IP Masq and a host of other services. It is written too Red Hat 6.0 and the 2.2.12 kernel. I am not affiliated with SANS, other than an attendee, but would recommend this to anyone getting started with Linux. A place to start if interested would be: http://www/sansstore.org If it suites your interest, then enjoy! 73, John
