Missing IPv4

[lljsullins]

So today I booted up my R710 with Ubuntu Server on it and I needed to change my ports for my Gmod server, I then typed in ifconfig to get it and it didn't pop up at all! I have no idea why, very very stressed out.

 

Thanks,

Liam

What does it say when you try:

sudo ip addr show

The problem is not that you are missing IPv4, but that you are missing other network interface(s). You only have loopback there, which is also important, but you should have other interface(s) too. Check BIOS if the adapters are enabled and cables are properly connected (usually lights should be visible near the port, if link is up).

 

@koen__2000 It won't help, if he doesn't have network interface available.

They are all connected, but the thing is I messed up my interfaces file, is there a way to restore it back to what it was before?

You need to know the interfaces names, then yes. I do not have any Ubuntu machines at hand right now, but "ifconfig -a" and/or "cat /proc/net/dev" may help you finding them.

# The loopback network interface
auto lo eth0
iface lo inet loopback

# The primary network interface
iface eth0 inet dhcp

This is default /etc/network/interfaces file. Replace eth0 with the network interface you have. Add more rows, if you have more than 1 interface.

So I have eno1, eno2, eno3, eno4. So I would do this? 

 

iface eno1 dhcp

iface  eno2 dhcp

iface  eno3 dhcp

iface  eno4 dhcp

Fixed it.

You forgot the inet from between, but glad you got it fixed.
