Can anyone tell me some free system-network administration tools?
Actually I am using nagios www.nagios.org and snort.

        A well-run server largely relies upon the administrator rather
than third party tools, but that is my opinion.  Nevertheless, a variety
of tools can harden a server and make life easier.

        I setup log processing and mailing, regularly run system scripts
for maintainence and notification via mail of notable changes over a
timeperiod, and a variety of other automation upon my own design.  It's
quite simplr really, I believe there are some script out there provided
for the public that do similar tasks.

        nmap serves handy, simply to verify the ports open.  It is not
necessarily a bad idea to run "John" [http://john.openwall.com/]
regularly to test for bad passwords.

        A lot of internal tools exist within operating systems that
people do not realize.  Linux provides fstab entries to limit filesystem
abilities; chattr to specify attributes to a file to prevent changes,
etc; you can have internal password expiry; quotas.. the tools are

        I like ViperDB vs. Tripwire, but some people may prefer
Tripwire.  They are filesystem integrity intrusion detection systems.

        All these things are well-documented.  Manpages and Google
should suffice for comprehensive reference.

        I could go on forever, I am always learning something new or
some way to make my servers better in some way.
