In initial configuration duration for the new appliance, my colleague just set the ip address, not did other operation.
Now, I hand over the work, I met a problem, when I log in the operation system, I found many of command can't be used in the unusual linux system.
So I used the 'ifconfig' command to change the IP address. It is ok, but this is temporary way, when the server reboot, the configuration will lost.
How can I change the IP address permanently?
Thanks the answer in advance!
