Ethernet Not Connecting - lee101 - 2007-04-02


Hi,

I've got a server running ubuntu, for file & web, it has been working fine ever since I set it up. Although recently the ethernet adaptor in it has stopped working, meaning that in order to make it connect to the network I have to de-activate & then activate it.

 

I can't understand what's causing this, since it was working one time, then when I rebooted it just went.

 

Anyone got any ideas?

 

Thanks,

Lee :)

What do you mean by deactivate and reactivate - as in plug in a cable and unplug it, or is it a wireless card and you're switching on and off?

I need to go into System>Administration>Networking Then click the Ethernet Connection, Choose Deactivate then click Activate

 

Also all the adaptor is set to



Code:
auto eth0
iface eth0 inet dhcp




in /etc/network/interfaces

Hmmm...

 

I have no idea what is causing this, but I have a (rather hacky) potential solution.

 

This is probably a really bad way to do it, so if someone more experienced has a better idea, then please listen to them and not me. :)

 

From the terminal:

 



Code:
sudo crontab -e




 

In the editor, press i and then type the following:

 



Code:
0 * * * * ifdown eth0 && ifup eth0




 

That will automatically stop and restart the connection every hour. This might be over the top, but it should work.

 

Now press Esc and type :wq followed by Enter (this saves the file and quits the editor).

 

Let us know if you have any luck - or if you don't! :P

Thanks,

I've just done that and restarted it, hopefully ethernet should kick in itself soon :)

 

Update: That didn't seem to work, I'm just wondering wheather I should just do a fresh install, which should be quite painless
