Manually Setting Up a Static IP in Ubuntu

For some reason, Webmin doesnt work well with Ubuntu 10.04. Everytime I configure a static IP using Webmin, it throws an error at boot. Ive reinstalled several times hoping that it was just a glitch. Maybe for some reason, there was a misconfiguration in the network modules in the source code perhaps.

Anyway, getting around this, I decided to be a command line ninja once more. Logging in as root, edit the /etc/network/interfaces file an tweak as needed (I removed the last octet for security reasons, replaced with x and y).
# The primary network interface
auto eth0
iface eth0 inet static

address 192.168.1.x
gateway 192.168.1.y



You could actually just copy some of the values when you're on DHCP by entering ifconfig -a as a sample, heres the data I got (I removed some values and replaced the last octet of the IP with x).
eth0      Link encap:Ethernet  HWaddr -- removed -- 
          inet addr:192.168.1.x  Bcast:  Mask:
          inet6 addr: -- removed -- Scope:Link
          RX packets:5140320 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1978783 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:946219572 (946.2 MB)  TX bytes:2233516408 (2.2 GB)
