[plug] NIC diagnostics

[Jon Miller]

Is there a way to check the condition of a NIC card in Debian.  I have tried several NIC (2 Intel Pro/1000 GT, 2 3COM and now I'm trying 2 Netgear).  So far the Intel and 3COM are not working.
Only 1 of the nics seems to work when 2 are present.  They both show up in lspci and they both load up as eth0 and eth1, but during a ping test only 1 will work.
These cards are plugged into a riser (which may be faulty), but there is no way to prove it.

I thought it would be best to troubleshoot the NIC separately first then work my way back to the riser.


Thanks
