[lug] Server slows down Internet

[Gordon Golding]

 I have network with PCs and a server on it.

Every once in awhile, the network slows down.

We've had trouble with old hubs before, but this looks like a connection to the server.

If I unplug and re-plug the cable into the server, the network seems to recover.

Any thoughts?

I look at the logs for that time, Only thing I see at all different is:

In ????? /var/log/secure

"subsystem request for sftp" after the ssh2 login, so I take it the person is opening a data transfer window

...
Accepted password for billybob from...<snip>... ssh2
... subsystem request for sftp
....


 
In ????? /var/log/messages

Not sure if this is anything at all...but..
