Reset your serverX and desktopX systems.

1. As the root user, edit the /etc/sysconfig/network-scripts/ifcfg-eth0 on serverX to add an additional address of 10.0.X.1/24.

   1. Append an entry to the file to specify the IPv4 address.

      [root@serverX ~]# echo "IPADDR1=10.0.X.1" >> /etc/sysconfig/network-scripts/ifcfg-eth0
      

   2. Append an entry to the file to specify the network prefix.

      [root@serverX ~]# echo "PREFIX1=24" >> /etc/sysconfig/network-scripts/ifcfg-eth0
      

2. Activate the new address.

   1. Reload the configuration changes.

      [root@serverX ~]# nmcli con reload
      

   2. Restart the connection with the new settings.

      [root@serverX ~]# nmcli con up "System eth0"
      

3. As the root user, edit the /etc/sysconfig/network-scripts/ifcfg-eth0 on desktopX to add an additional address of 10.0.X.2/24 and load the new configuration.

   1. Modify the file to add the IPv4 and network prefix.

      [root@desktopX ~]# echo "IPADDR1=10.0.X.2" >> /etc/sysconfig/network-scripts/ifcfg-eth0
      [root@desktopX ~]# echo "PREFIX1=24" >> /etc/sysconfig/network-scripts/ifcfg-eth0
      

   2. Reload the configuration changes.

      [root@desktopX ~]# nmcli con reload
      

   3. Bring up the connection with the new settings.

      [root@desktopX ~]# nmcli con up "System eth0"
      

4. Test the connectivity using the new network addresses.

   1. On serverX, verify the IP address.

      [root@serverX ~]# ip addr
      

   2. On serverX, ping the new address of desktopX.

      [root@serverX ~]# ping 10.0.X.2
      

   3. On desktopX, verify the IP address.

      [root@desktopX ~]# ip addr
      

   4. On desktopX, ping the new address of serverX.

      [root@desktopX ~]# ping 10.0.X.1
