Networking problems after power failure

Postby port13 » Wed Sep 07, 2011 12:19 am

So everything was working fine until I lost power at my house. When I powered on my amahi server, I had a boot message that said dhcpd failed. When I started investigating I found eth0 was down. Every time I reboot I get the same results. I ran through the Amahi interactive network troubleshooter and this is what I got:

Using the Network Troubleshooter, I failed step 4 - DNS resolving for internal hostnames. Here's a paste to help troubleshoot: http://pastebin.com/GREDM43H

Any help would be greatly appreciated!

Is your router working?

Can you reach an outside IP address?

Try:
ping -c 1 8.8.8.8

It should succeed with 0% packet loss.

Yes, router appears to be working. However, no internet connection for the amahi server. I have internet access from my win7 machine and can ping 8.8.8.8 as well as my router's external ip. But no luck from the amahi server. When I try to ping 8.8.8.8 or my router's external ip I get the message "connect: Network is unreachable." The amahi server can ping my internal gateway ip and it can ping my win7 machine.

Any other ideas? Thanks :)

Have you checked your error logs for anything obvious? (/var/log/messages)

If you haven't looked at it before, I suggest starting at the bottom of the file and work upwards looking for errors related to networking.

Well, things have gotten worse. I rebooted the machine and now it won't even restart completely. It just freezes at the fedora splash screen.

What would be the best thing to do now?

Sounds like a disk or hardware problem.

Can you boot in single user mode? If so, I would explore the error logs to see what might be causing the problem.

You might try booting the system with a live cd. Mount the root drive and look at the error logs (in /var/log)

If you can, check the disk SMART data to see if your drive is dying.
