[SOLVED] Internet connection config problem

[ElWray]

Hey y'all,
I just finished installing the OS (first time ever w/ linux...yay) and I got some serious problems trying to configure my internet connection. I've tried creating a new connection with the same settings i had on my previous OS (static ip address, and all that stuff). The connection icon in the taskbar goes green but for some reason I can't connect to the internet.
Some advice would be much appreciated.

Thanks,
ElWray

Re: Internet connection config problem

Did you have your ethernet cable connected when you installed Kubuntu? Did you try networking with the Live CD, prior to installing? It's a bit unusual to have problems with ethernet. Here's good guidance:

If you meant to say "wireless" or something like that, take a look at the "Top 20" in my signature -- lots of help there.

Re: Internet connection config problem

Nope, not wireless. Normally I'd just have to plug in the cable and write down the IP address, etc. I didn't try networking w/ the Live CD just cause i've seen kubuntu in action on another pc

Btw...can't find eth0

Re: Internet connection config problem

Run

ifconfig -a

in a terminal and post the results.

Re: Internet connection config problem

Eth0 is there.

So if you follow the instructions in the link provided in dibl's post, you should be up and running in a short time.

Re: Internet connection config problem

if i just type "ifconfig" instead it won't show up anymore

and i cant save the interfaces file after modifying it. also i can't seem to find /etc/resolv.conf
just a folder called resolvconf

EDIT: Problem fixed.

However, when I try "sudo /etc/init.d/networking restart", it fails

/etc/network/interfaces:7:misplaced option
ifdown: couldn't read interfaces file "/etc/network/interfaces"
/etc/network/interfaces:7:misplaced option
ifup: couldn't read interfaces file "/etc/network/interfaces"

Re: Internet connection config problem

Yes, the difference in ifconfig and ifconfig -a is that ifconfig only shows active interfaces, as ifconfig -a shows all interfaces. Your eth0 interface is present, but is not yet active. If you opened the interfaces file as sudo, using kdesuo to open your text editor, you should be able to save it. You may not have a resolv.conf file yet, as it is automatically generated when you connect if using DHCP. If using DHCP there is no need to edit this file. If you wish to use a static IP, then you need this file. If you open your text editor with the kdesudo command you can create and save the file.

Very carefully edit your interfaces file again, it appears you have an error, probably a simple typo.

Re: Internet connection config problem

hm...still not working.

Here's the file's content:

auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0

auto eth0 inet static
address 82.76.180.253
netmask 255.255.255.128
gateway 82.76.180.129



i got the first half exactly like in the example. is there something else i should actually type there instead?

Re: Internet connection config problem

So what did you put in your resolv.conf file? You might try it with dhcp just to see if you can get connected.

auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0

auto eth0 inet dhcp

Re: Internet connection config problem

Tried now and it worked.
Another problem. I restarted and the interfaces file was empty.

I still can't connect to the internet tho'

Re: Internet connection config problem

Sorry for double posting. Seems like it worked now with the static IP address.
[problems solved]

Thanks a lot
