Configuring a network interface
To configure an interface permanently you'll need to edit the interfaces file, /etc/sysconfig/network-scripts/ifcfg-eth0
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/sysconfig/network
NETWORKING=yes
HOSTNAME=machinename.ece.utexas.edu
GATEWAY=128.83.xxx.xxx
sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0
Note: if there are more than one network adapter, you will see multiple interfaces, (e.g. ifcfg-eth1, ifcfg-eth2, etc). Select the one that requires a static configuration.
DEVICE=eth0 BOOTPROTO=STATICDHCPCLASS=HWADDR=00:30:48:56:A6:77IPADDR=192.168.0.5 NETMASK=255.255.255.0 ONBOOT=yes
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/network stop sudo /etc/init.d/network start
