[SOLVED] "ifconfig eth0 up" doesn't work, cause of "no such file or directory"

Sebi94 · 08-19-2012, 07:15 AM

Hello community!
I've got a problem with my network. I've rebooted the system and after it, the network couldn't come up. I entered the command "ifconfig eth0 up". The error message sayed, that no such file or directory available is. I think it's exactly this error message:

Quote:

SIOCSIFFLAGS: No such file or directory

I also stoped and started the /etc/init.d/networking. The /etc/init.d/interfaces is always the same, like before as it still worked fine. DMESG also doesn't say something interesting.

Well, I haven't got any idea left. Can you help me?

Thanks forwarding!

Which distro? The ifconfig command has been deprecated and many distros have switched to its replacement, the "ip" command. Using the new ip command, the equivalent to "ifconfig eth0 up" would be:

# ip link set eth0 up

For ip eqivalents to ifconfig typical commands see generally:

Shows "lo", "eth0" and "eth1". eth0 has the right address, but is down.

There are some informations, which are normal and one, which I think, it's the error:

Any idea?

Does your NIC show up in lspci?

And the NIC module in lsmod?

It's shown in lspci and lsmod.

I loaded the module manually again. I edited the /etc/inittab and
I reconfigured the Kernel of Linux and the broadcom NIC.

And I also restarted the inetd, network-manager and tried to get up the Interface with ip link Set eth0 up and ifup eth0 and ifconfig eth0 up.

Any other ideas?

I found the mistake... It was a missing firmware (the second one, but it needs the first one also):

Quote:

firmware-linux-nonfree

Quote:

firmware-linux

After the installation of this two packages and a reload of the config and a reboot, the network still works again.

Thank you for helping!
