[ILUG] FTP and other services ceasing to function...

[Richard Eibrand]

Distro: Redhat 7.2
Kernel: 	2.4.7-10
	2.4.10
	2.4.14

Firewall: Non existent (Disabled)
Networlk Card: 3CCCom575CT-D (PCMCIA NIC)
Lan: 10mb Novell network.

This is the first time this problem occured. 
The box is connected in a 10Mb 10 port Genius lan hub with a crossover cable making the connection
between the patch in the wall to the hub. Hub connection set to normal as opposed to crossover.

The two other boxes connected to hub, who do not loose network connection when said machine goes down.

I ran mii-tool before and after it stopped shipping traffic, same result for both scenarios
-> eth0: autonegotiation failed, link ok

Once, the traffic has stopped shipping, none of the above work.

All firewall rules disabled

It seems to crap out after about a 20Mb transfer, could it be a transfer limit somewhere, but if so, 
how does that explain the link going down for other programs that use the connection.


Cheers for your help lads,
