eth0 has me stumped

[pretentious]

So for a while i've wanted to set up my own server. I started off playing with an old computer that came preloaded with win 97 that the family didn't bother throwing out coz it still worked. Thing is the moment i installed ubuntu server on the machine, it seemed unable to see the network. I have spend hours trying to figure it out until finally giving up and deciding that i could just buy newer hardware and it would likely work better. Now i've bought a raspberry pi, enabled ssh and thought i'd just get networking set up and i can remote into it from then on. I see that there is no ip address on eth0 so i use ifup eth0 and it failes to find a dhcp responce. i had tried to edit the /etc/network/interfaces file but it didn't seem to help. So i have once again given up. I know i havn't really provided much detail on what specifically i've tried but It all looks pretty straight forward to me, i've plugged in the cable, have a router with a dhcp pool, shouldn't this stuff just work? I've realised now that i can't get my trusty laptop to configure eth0 either so it might be my lack of education. Do you guys have any ideas?

Hrm. Never actually had to set up eth0. What exactly did you do with the interfaces file?

Since ive recently installed ubuntu server on one of my machines, I ran into the same exact problem as you, I remember that a little bit of toying with the /etc/network/interfaces file and either resetting the interface or the whole system fixes it. Since I love my server so much, I completely forgot the password on it and am currently reinstalling it. In the mean time, please post the contents of /etc/network/interfaces

as I remember, I think you have to add the following to /etc/network/interfaces to have it configure it automatically;

Code: Select all

auto eth0
iface eth0 inet dhcp

thanks for the replies. I added that autho eth0 so it ran on boot and allow-hotplug

Code: Select all

auto eth0
allow-hotplug eth0
iface eth0 inet dhcp


turns out however that my flawlessly tech savy landlords didn't label the ports correctly.. i think. I could plug the cat5 cable in but it wouldn't connect. I found a working port and now have a network connection
