Configuring IPv4

Now that we've established a link between the machines, let's put some IP addresses on the systems so that we can communicate between them. For now, let's look at manually configuring IP addresses rather than auto-configuring them via DHCP.

How to do it…

We need to manually configure the IP addresses using the ip command. Let's start with server 1:

# ip addr add dev eth0 10.0.0.1/24
# ip addr list eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:6e:8f:ab brd ff:ff:ff:ff:ff:ff
    inet 10.0.0.1/24 brd 192.168.251.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::20c:29ff:fe6e:8fab/64 scope link
 valid_lft forever preferred_lft forever ...
