losing my network connectivity to server

[FoBoT]

i have a red hat 7 (e-smith) based server running samba.

i am losing connectivity to the mapped drives from winders 95 client pc's

i went to the server and tried to ping the gateway box and it is no go. ifconfig still shows eth0 as up/ok

so i think it isn't a samba problem at all, more likely the nic itself (somebody told me this nic was flaky) or the tcp/ip or network stuff itself, maybe?

are there any log files in /var i can check to see if the eth0 is dying? or something like that?

i am going to switch the nic and see if that fixes it

just hoping there is something i can learn about linux logs here :D

i replaced the nic, so far so good, but i would really like to pin down if it is a nic problem or something in linux

anybody got any suggestions on a way to tell from my logs??


thanks

have a nice day!! :)

I recall something about connect timeouts in samba .. especially if you require authentication of the connection... I can't recall where I read it rightnow ..

Essentially the idea was that if the connection was established for greater than x time, force a reconnect to reauthenticate.

don't think it is authentication or samba related, cause i couldn't even ping out from the server. totally lost network connectivity.

i re-booted the server once after the first time it happened. this fixed it, but only for about 15 minutes, then poof, gone again

it has been back up on the new nic for about an hour with some heavy data transfers and looking good so far

I had a similar problem, it would write to /var/log/messages something about tx errors on eth1, in my case. Look for the example..... I'll see if I could find it later, sorry
