Configuring a network interface

To configure an interface permanently you'll need to edit the interfaces file, /etc/network/interfaces 

Note:  The addresses below are provided as an example only.  ECE-IT will provide the appropriate addresses when a formal request has been received.

Open a terminal window and proceed with the following:

 sudo vi /etc/network/interfaces

## To configure a dynamic IP address
auto eth0
iface eth0 inet dhcp

## Or configure a static IP
 auto eth0
 iface eth0 inet static
   address 192.168.1.14
   gateway 192.168.1.1
   netmask 255.255.255.0
   network 192.168.1.0
   broadcast 192.168.1.255

For these settings to take effect you need to restart your networking services.   

 sudo /etc/init.d/networking restart

Setting up DNS

To cause your machine to consult with a particular server for name lookups you simply add their addresses to /etc/resolv.conf.  

 sudo vi /etc/resolv.conf

enter the following details  

 search ece.utexas.edu
 domain ece.utexas.edu
 nameserver 128.83.185.41 
 nameserver 128.83.185.40

Restart the networking service

sudo /etc/init.d/networking restart
