Good linux network/server monitoring software

[Steve_Oaks]

I need a good server moniter application for linux. I need to monitor any and everything network related. Im good at watching my logs but I need to make sure and keep some script kiddies in check.

Could you perhaps be a little more specific? "any/everything network related" sounds to me like you want a very, very large, fast disk, a constantly-running tcpdump session on each interface, and an encrypted handoff of the logged traffic to a remote, centralized logging host (NOTE: This is how some security systems approach centralized logging of network traffic, for later analysis).

If you can narrrow down what it is you need to monitor, we can probably suggest more appropriate tools (e.g., a simple password-protected SNMP query via an encrypted tunnel to obtain up-to-the-mircosecond network interface statistics).

Note also that neither of the suggestions I describe above are pre-packaged "tools" in the sense that you'd tar xzf a gzip'd tarball, ./configure && make && make install and be done with it. It'd require a bit of shell scripting or Perl scripting or $LANGUAGE_OF_CHOICE scripting to glue together existing tools (e.g., ssh, tcpdump, scp, the snmp toolkit (under whichever University's banner is distributing it now; I remember it as the UCSD toolkit).

Take a look at MRTG and BigBrother. Big Brother can monitor MRTG as well as other stuff.
