I recently installed ubuntu 8.10. I need to setup my ethernet connection manually. Everytime the computer starts the ethernet settings are changed to Automatic DHCP and to get my ethernet working I need to manually enter the IP,netmask,gateway etc. each time I log in. Please give me a fix to this problem.
Thanks.

If you don't want to use dhcp then you need to disable the dhcp client and then manually edit the /etc/network/interfaces file. Once disabled the dhcp client won't keep rewriting that file for you.

Depends on your dhcp client but it may be,

/etc/init.d/dhclient stop

and if I recall correctly,

update-rc.d dhclient stop

so that it doesn't do it on boot. Now I guess you know how to set the interfaces since you have been doing that each time. Enter that info into the file above. See,

man interfaces

I suggest you amend /etc/network/interfaces file like this:
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.1.108
netmask 255.255.255.0
gateway 192.168.1.254Substitute your details as necessary. If Network Manager is installed, I would remove it in Synaptic. Reboot and enjoy.
