ifconfig — stdin stdout - file -- opt --help --version
Synopsis
ifconfig [options]interface
The ifconfig command is an
ancestor of ip. It is still found
on many Linux systems but is less powerful (some would call it
obsolete). We’ll cover a few simple commands here, but you should be
using ip instead.
To display information about the default network interface (usually called eth0):
$ ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:50:BA:48:4F:BA
inet addr:192.168.0.10 Bcast:192.168.0.255 ...
UP BROADCAST RUNNING MULTICAST MTU:1500 ...
RX packets:1955231 errors:0 dropped:0 overruns:0 ...
TX packets:1314765 errors:0 dropped:0 overruns:0 ...
collisions:0 txqueuelen:100
...This includes your MAC address (00:50:BA:48:4F:BA), your IP address (192.168.0.21), your netmask (255.255.255.0), and various other information. To view all loaded network interfaces, run:
$ ifconfig -a
