I've got a problem on our network where a router log shows it's ethernet connection is being reset often due to 'late collisions'. Searching google seemed to indicate a computer connected to it may have a faulty network card so I need to try to find the offending machine.
also keep in mind that often "late collisions" are usually due to a full-duplex-only adapter being attached to a passive HUB. They generally aren't the result of hardware failures, but it is possble.
Check the machines involved and see if they are all properly set for the right duplex.
Overly-long cables can also cause this problem.
Is there anyway I could use snort (or winpcap) to detect/report on these late collisions? (even to only show if they are happening or not). Or is it not possible as packets get discarded by the hardware?
hmm, not sure.. however I'd suspect if your router is complaining, they *are* happening.
