I am a Debian user.

A couple days ago, I did a dist-upgrade to move from squeeze to wheezy.

When I rebooted, I found that I had no networking capabilities.

I get a number of network-related error messages, but this one comes up first so I assume that the other problems derive from this one:

Configuring network interfaces...:
"failed to open statefile /run/network/ifstate: No such file or directory"

I'm not sure what to make of this message.

Nor do I know why there would be a difference between squeeze and wheezy in this regard.

If anyone has any ideas on how I can diagnose and fix this problem, I would be very appreciative.

Thanks.

What do you get when you run "ifconfig -a" from the command line?

output from ifconfig -a:

eth2 Link encap:Ethernet HWaddr 00:19:d1:6c:a4:dc

RX packets:0 errors:0 dropped:0 overruns:0 frame:0

I was able to resolve the problem with statefile by using this workaround that was recommended by someone who had encountered the same problem:

by modifying /etc/init.d/networking and adding a line [ -d /run/network ] || mkdir /run/network immediately on line 53 immediately after start)

But now I still have no network on startup: the "configuring interfaces" step says that eth2 is not recognized. Same result if I run ifup manually.

However, it seems from the output below that ifconfig does recognize eth2.

Don't ifup and ifconfig get the hardware information from the same source ?

Fixed the problem.

In the /etc/network/interfaces file, I had inadvertently commented out this line:

iface eth2 inet dhcp

smallpond, thanks for your help.
