Could somebody recommend me some good
 network "sniffer" software that could be used
 to intercept data on the LAN where I am sysadm.

 I would like to test security of our corporate
 LAN (some 300 workstations, 25 servers)
 which is entirely based on HP Procurve
 switches (so, therefore there is no single
 broadcast Ethernet domain). In short, I would
 like to see if it is still possible that someone
 installs some network equipment (PC+software)
 and "sniff" data on the network.

 Any pointer to software that could be used
 for testing or any other related URL is
 more than welcome.
