[Nagios-users] Packet Monitoring

[Wilcox, C. <wi...@tr...>]

I have a problem.  

Using MRTG and Nagios I have determined that some very large data transfers
are happening after hours. How do I pin down exactly who and what is being
transfered??

I could use a sniffer but don't know which one could run all night and
capture all packets on the network.  Anyone know of a tool to help with
this??

Thanks in Advance.
