DGE-530T Network Card: Works for a little while

[ThomasJ02]

I've got two brand-new DGE-530T gigabit ethernet cards on two different machines connected via a crossover cable. I'm using the sk98lin driver (although I've also tried the skge driver). The network card is found by both machines, and I have link lights on both cards. Here's the output of /sbin/ifconfig:

Machine 1:

On both machines, I can ping the other immediately after doing a '/etc/init.d/net.eth1 restart'. But then I try to ssh from one machine to the other (which fails), and when I try to ping again, I get 'destination host unreachable.' Any idea what's up with this totally weird problem? Here's the sequence of events:

Code: Select all

 *     Shutting down eth1 ...                                             [ ok ] 
* Starting eth1
 *   Bringing up eth1

What kernel are you using.

Skge has never worked for me or a lot of others. We keep being told to use/try it, but to no avail has it ever worked for me. Sk98lin worked fine (patched from syskonnect) with my 2.6.11-gentoo-r5 kernel. But neither is working with the 2.6.13-gentoo-r3 kernel.

EDIT: ** Finally got Skge working with the vanilla 2.6.14_rc5 kernel.

Yes, that's the problem right there I believe. These cards are gigabit ethernet cards. Gigabit ethernet requires a straight through cable (CAT5E). NOT a crossover.

Sounds weird I know... but anyway. Try a straight-through and let us know what happens.
