Packet Sniffer

[daverji]

Can anyone recommend a packet sniffer for me to play around with?
Preferably a cheap or free one, that's easy to use. Something for Windows would be nice, easy, and make my life easier, but I'll take a shot at a Linux one also.
I'm looking to get into my LANs guts a bit.
Thanks for your time.

Try and find CaptureNet and SpyNet. Or ethereal. CaptureNet and SpyNet got bought by eeye.

You can play with this for 14 days ($39 after).

Sniffer is designed for interception and analysis of the packets going through the network.

Enjoy.

ethereal is probably one of the best, it is free, and works on a variety of platforms.

Tcpdump and snort are essential tools of the trade. They work on just about every type of *NIX you can name. Be sure to use tcpdump 3.6 and not the outdated version that comes with Redhat.

windump for Windows machines. But ethereal will do everything tcpdump does, and more. I use tcpdump atleast weekly, its a great tool, but ethereal makes it easier

WindowsXP includes the command line utility netcap to do a capture,
you'll still need ethereal to view the trace
