Reset your desktopX system.

1. Create a new connection with a static network connection using the settings in the table. Be sure to replace the X with the correct number for your systems.

   Parameter	Setting
   Connection name	lab
   IP address	172.25.X.10/24
   Gateway address	172.25.X.254
   DNS address	172.25.254.254

   [root@desktopX ~]# nmcli con add con-name lab ifname eth0 type ethernet ip4 172.25.X.10/24 gw4 172.25.X.254
   [root@desktopX ~]# nmcli con mod "lab" ipv4.dns 172.25.254.254

2. Configure the new connection to be autostarted. Other connections should not start automatically.

   [root@desktopX ~]# nmcli con mod "lab" connection.autoconnect yes
   [root@desktopX ~]# nmcli con mod "System eth0" connection.autoconnect no

3. Modify the new connection so that it also uses the address 10.0.X.1/24.

   [root@desktopX ~]# nmcli con mod "lab" +ipv4.addresses 10.0.X.1/24
   

   [root@desktopX ~]# echo "IPADDR1=10.0.X.1" >> /etc/sysconfig/network-scripts/ifcfg-lab
   [root@desktopX ~]# echo "PREFIX1=24" >> /etc/sysconfig/network-scripts/ifcfg-lab
   

   Or alternately:

4. Configure the hosts file so that 10.0.X.1 can be referenced as "private".

   [root@desktopX ~]# echo "10.0.X.1  private" >> /etc/hosts
