Hello everyone,


I posted this awhile back, but it didn't come up. So, here it is again.

I have a nice machine with one of the first G-NIC - 1 cards. The card's module, 
yellowfin, comes right up and so does the eth0 interface. The networking 
configuration is the same as a box (exact dup in WinNTSvr) and it works great! 
The RedHat box, though, cannot ping anything but itself. 

The card runs via fiber to a Cisco Catalyst 5500. Both sides show activity on 
their respective fiber channels, but no link light at the Switch. The same fiber 
works with another machine, and this machine works with any other 100Mbps ether 
card I stick in it.


I called Packet Engines and they say they are not sure, but disable 
'auto-negotiation' at the Cisco level. This being done, I still am unable to get 
a link light or network activity.

My own opinion is that the hub, if also, packet eng..., might work. But I do not 
have one to try.

Ideas? Suggestions?

TIA

Sincerely,

--Chris
