[techtalk] network monitor

[Tech Docs]

newbie here. What is the best network monitor and sniffer tool for Linux. I
am using Linux on my ibm thinkpad i series running on pentium 266 and 128 mb
ram. i would like to realize the power of linux in network monitoring,
bandwidth analysis and sniffers. where do i start? i am quite familiar with
solaris and good in networking as such.

also are there any interesting articles on linux security available online?

Cheers!
Sriram
