: error fetching interface information: Device not found


I am getting the following two errors and for the life of me can't find out why. Searches just bring up more questions.

If I run ifconfig from the command line I get this:

: error fetching interface information: Device not found

If I run nmap I get this:

Failed to find interface eth0 mentioned in /proc/net/route

The funny part is, everything seems to be working fine. I am connected to the Internet, I can connect to my LAN, my web server is working - so not sure what the problem is.

Any ideas?

This is /proc/net/route

Iface Destination Gateway Flags RefCnt Use Metric Mask MTU Window IRTT

eth0 003AA8C0 00000000 0001 0 0 0 00FFFFFF 0 0 0

lo 0000007F 00000000 0001 0 0 0 000000FF 0 0 0

eth0 00000000 013AA8C0 0003 0 0 1 00000000 0 0 0

Thanks

I'm assuming it is. It is in the fstab file and should get mounted at boot. I don't see any error messages that it hasn't been mounted.

This was working fine last week, and as it is mainly used for a web server I rarely look at it, other than to upload files to the website.

Hmm. Is eth0 definitely the interface in question? Like, is it the ONLY interface on that machine, and named eth0 for sure? For instance, I have eth0, dummy0 and lo. eth0 according to lshw shows as enabled, dummy0 shows as disabled, and lo doesn't show up at all.
Try lshw at the command line (if you have it installed) and see what it lists for interfaces.

No lshw, but strange enough ifconfig eth0 is working now. However, nmap still has issues.

nmap -vvsT my.domain.com produces this error.

Failed to find interface eth0 mentioned in /proc/net/route

But this works.

nmap -vvsT -P0 my.domain.com.

Go figure.

I also have a lo, which is the loopback device.

Did you ever figure this out? I have seen the same thing on a couple servers running slackware, the one I'm working with today has Slackware 10.2. Well, at least the error about not being able to fetch interface information, but I'm logged into the machine remotely and everything seems to be working fine. The servers I work on also have a tun0 device.
