Unable to connect to internet via ethernet after tweaking interfaces and hosts file
 
Hi I have been trying to set up a file server following the guide found here: http://www.howtoforge.com/ubuntu-home-fileserver-p3

I was having issues with ubuntu not finding the host name when I used the query host name -f (see step 5 of howtoforge guide)

I eventually realised I had not edited the /etc/hosts file and /etc/network/interfaces file properly

I edited them to match as suggested on the howto guide.

eventually I successfully found I that I was able to find the
host name and I moved onto the next step which was to update the system.

However I no longer have internet connection via Ethernet I look on the web for a solution and a suggestion for diagnostics was

Code:
sudo ifconfig
sudo route
ping -c 4 www.google.com
I did this and the output is below:
Code:
root@trimdonserv:/home/j# ifconfig

I'm not sure what I have done to be honest and I am pretty annoyed with myself for messing it up.

I am running on a new install of ubuntu 8.10

Many thanks for any assistance

Have you set up a DNS server in your /etc/network/interfaces file?
If might be helpful if you posted the contents of that file.
cheers,

looks weird if your address is 192.168.1.x but broadcast is 192.168.0.255

assigning ip via dhcp or static?
