Perform the following actions to isolate the problem to either the client or the server machine.
Problem
The DHCP server machine is not working.
Verification: Log in to another machine on the same subnet as the client, and use the ping command to try to reach the server.
Solution: Diagnose the problem on the server machine.
Problem
The DHCP server is not running.
Verification: Log in to the server and enter the command:
ps -ef | grep dhcp |
Solution:
Stop and restart the DHCP server.
Enter the command:
/etc/init.d/dhcp stop |
Wait about 10 seconds. Then enter the command:
/etc/init.d/dhcp start |
Problem
The boot process hangs during DHCP.
Verification: The interface is marked primary, but no valid DHCP transaction has occurred.
Solution: Interrupt DHCP by typing control-C. The boot continues.
Although booting continues, the host may be incorrectly configured for the networks to which it is attached.
