From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) Description of problem: The dhcp client in redhat 7.2 running on an intel machine is not sending it's hostname to the dhcp server. Therefore, the client receives an IP address but receives as a hostname the default hostname configured for the scope. I inspected my dhcp server's log which contains all the traffic between client and server among other things and did not see the hostname passed for my redhat machine. I did a release/renew on my windows XP box and did see the hostname being passed. So for whatever reason the client is not properly sending its hostname to the server. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Release and/or delete the lease assigned to the client 2. Reboot the client 3. Inspect lease file after client receives address and see that it's hostname is not properly registered with the IP it received. Actual Results: Client received an IP address but the hostname registered for it in DNS was the default hostname assigned by the server Expected Results: I expected the client to properly send its hostname to the dhcp server. Additional info:
You need to add a line of the format: DHCPCDARGS="-h hostname" to /etc/sysconfig/network In most situations the server has the correct knowledge of the hostname, and not the client, thus a default setting that doesn't work in your situation.
