No network connectivity after Install

[GSG]

Hi - I'm quite a linux newbie and was very impressed with Kubuntu running from the CD so I did a complete fresh install with HD format.

The installation worked like a dream but I can't get the network & internet access working, it worked (and still does work) perfectly straight away with the version running off the CD so I tried messing about with the network settings but nothing so far works.

The Nameservers are appearing in /etc/resolv.conf, DHCP is setting the ip address correctly, all settings seem to be exactly the same as with the version running off the CD but I can't look at any pages and I can't ping any other machines on the network. Any help would be appreciated...thanks

Re: No network connectivity after Install

look at the /etc/network/interfaces file...comment out all the interfaces you DONT need...but leave lo anyway...default first network card is eth0 so..

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

put a # infront of all the other lines...

Re: No network connectivity after Install

Done, but it doesn't make any difference... I had a couple of extra lines underneath 'iface lo inet loopback' for address and netmask, I guess from my fiddling about with the network settings - so I commented these out too and rebooted, still nothing.

Re: No network connectivity after Install

Hi,

there's two things which look strange to me :
you have quite a lot of errors :
RX packets:21 errors:16 dropped:0 overruns:0 frame:0
TX packets:12 errors:6 dropped:0 overruns:0 carrier:6

By pinging host on the net, it seems that you have nothing in /etc/resolv.conf, no ?
Can you add your dns server lines in it ?

Cheers

Re: No network connectivity after Install

no, as I said at the top - my resolv.conf has the DNS lines:

nameserver 213.1.119.103
nameserver 213.1.119.104

Thanks for the help so far...I just tried Fedora (Core 5) and that has the same problem...

Re: No network connectivity after Install

I just attempted to install Mepis and the network/internet access is good from the cd (as with kubuntu) but for some reason it isn't letting me do a full install (keeps saying 'Failed to create required partitions. Returning to Step 1.')

I might try plain Ubuntu...

Re: No network connectivity after Install

Got it fixed

I installed MEPIS over Kubuntu and it works perfectly. I slightly prefered Kubuntu, but they're virtually the same now that I've trimmed some of the extra stuff from the panel. Thanks for the help anyway...
