<sigh> That was it. Linking the 2 boxes with a crosslink and putting
both at autoselect makes them switch to 100baseTX.
On the client:
input (Total) output
packets errs bytes packets errs bytes colls
2027 0 133782 2382 0 3605108 0
I haven't bothered to check on the server, the results being obvious.
So this means the patch on the rl works, since this (media autoselect)
wasn't working before.
But now I feel kind of bad, since there's got to be something I clearly
misunderstand about the protocol.
Both interfaces are capable of doing 10baseT/UTP. Why are they doing
100baseTX? Can't I run those in a 10baseT network??? Does this mean I
must buy a 100baseTX hub?
I still believe there is something wrong with the vr since it is
something external to the server that made it freeze, so it's a kind of
DOS. It shouldn't happen, IMHO.
Thank you for your help. I'm still available to test my situation some
more.
A.
