Objective
The ifconfig
command has been deprecated and thus missing by default on CentOS Linux.
# ifconfig bash: /usr/sbin/ifconfig: No such file or directory
The new and recommended alternative for examining a network configuration on CentOS Linux is ip
command. For example to use ip
command to display a network configuration run the following:
# ip address
The above ip
command can be abbreviated to:
# ip a
If you still prefer to use ifconfig
command you can easily install it as part of the net-tools
package.
