[plug] Fedora network issues

[Ben Jensz]

I've been having issues with a box running Fedora.  Basically what has 
happened is that the network traffic on the machine has pretty much 
stopped working properly.  It was working fine up until Friday morning 
and absolutely nothing was changed.  It all of a sudden started dropping 
connections that were active (Samba shares, ssh connection etc).  Now 
the machine can only be pinged by other machines on the local net, but 
when trying to access it any other way the network connection appears to 
initially start, but just dies.  For instance logging in via ssh, gets 
as far as asking for a username and then the connection just dies 
unexpectedly.

Now the other thing is that the machine can't ping anything else on the 
local network, apart from the very rare single ping reply from maybe 100 
ping requests being sent (and even then it might not reply)... keeps 
dieing with "Destination Host Unreachable".  Now this problem has me 
stumped for the moment.  The machine is an IBM x235.. so it has onboard 
broadcom gigabit ethernet...  I've looked at everything I could think of 
on the machine itself to see if I could locate the problem, but 
everything seems to be fine (and I hadn't changed anything that morning 
anyway).  I've checked network cables, I've put in another NIC to see if 
that made a difference as apparently a few people have had issues with 
an early broadcom driver (new NIC was an Intel Pro 100+ - so uses a 
different driver), but to no avail.  I've done the usual "Windows" 
troubleshooting technique (i.e. rebooted it multiple times)... and I 
can't seem to figure it out.

Anyone got any suggestions as I'm lost a bit at the moment :o(
