ifup / ifdown
The simplest commands for network configuration simply activate and deactivate and network adapter
ifup eth0
ifup ifcfg-eth0
ifdown eth0
ifdown ifcfg-eth0ifconfig
The ifconfig command allows much more control over the network settings. In its simplest use it lists all currently active network adapters. Adding the '-a' flag will list all available adapters.
If you want to see the details of the specific adapter this can be passed to ifconfig. To see only the configuartion of eth0 run 'ifconfig eth0'
[root@head ~]# ifconfig

ifconfig eth1 172.28.0.5There are too many options to show examples of here, but the options available are shown in the table:
