Are the lights on, on the switch's ports that you are using?
Have you rebooted the switch? Are you able to connect with other
machines or ports (say a laptop)? Is the light working on the
nic? Cabling good? If you have multiple nics you should stop/start
them and see if you can get one to work, sometimes one works when another
won't. service network stop, ifup eth0, ifup eth1, etc. Look
at your dmesg and see whether it finds your eth0 or eth1, that'd be nice to
know....
If you are able to narrow it down to the one FC2 box (and
within the os), then I would say that lastly you should run a chkrootkit
utility on the box to see if you have been own3d.
I
ran chrootkit and I found this:
Checking `bindshell'... INFECTED (PORTS: 1524 31337)
Checking
`lkm'... You have 12 process hidden for readdir
command
You have 12 process hidden for ps
command
Warning: Possible LKM Trojan installed
This
looks like a problem!! What is bindshell? I did a locate but could
not find it installed. What do I need to do?
TIA

Hello,
This
is strange! I don't even know where to
start. Everything was working
fine until yesterday about
1:00PM.
I am running a FC2 system. I have a dynamic ip
using ddclient to update. I
run ifconfig and I have an ip
address. I can ping it with no problem. I
can ping
other internal hosts. My ip is current with my dynamic
dns
provider.
I have changed out network cards and even bought a
new switch. Still no
internet connectivity. DSL
modem works fine as it is currently connected to
this PC. So its not an
ISP or modem problem.
I have not updated any packages since
04-01-05. I have been out of town ten
days and was able to
access my server remotely, even yesterday morning. I
have made no changes
to any files. Internet connectivity just stopped.
Any
ideas where to begin? I have been looking over logs and don't
see
anything wrong.
TIA
