How to obtain a new IP address from DHCP server in Linux ?

Question

My CentOS-7 home server has a static IP address.

Is there a simple way of organizing the hpptd server so that it is accessible through this address at a remote host, but is accessed at its 192.168 address by a laptop on the WiFi LAN?

Answer 1

Below are two different methods of how this can be done at the command line:

ifconfig eth0 down

Running the above command would take the eth0 interface (the first network card) down. Which is the same as releasing the IP address from that network card.

ifconfig eth0 up

After the interface is taken down, typing in the above command would bring that interface back up.

or

dhclient eth0
