== Part 4: How do I test my dhcpd service on my virtual network?==

# On a centos3 terminal window make sure that the command <code>tail -f /var/log/messages</code> is running.

# On your centos2 VM, change the configuration of '''eth0''' (or your interface name) to receive dynamic address configuration.

# Save your changes and restart the <code>NetworkManager</code> service.

# Observe the messages that get logged. You should see output similar to the following:

Mar 24 13:28:24 centos3 dhcpd: DHCPDISCOVER from 52:54:00:61:00:e7 via eth2

Mar 24 13:28:25 centos3 dhcpd: DHCPOFFER on 192.168.235.51 to 52:54:00:61:00:e7 via eth2

Mar 24 13:28:25 centos3 dhcpd: DHCPREQUEST for 192.168.235.51 (192.168.235.13) from 52:54:00:61:00:e7 via eth2

Mar 24 13:28:25 centos3 dhcpd: DHCPACK on 192.168.235.51 to 52:54:00:61:00:e7 via eth2
