I am looking to use the update-conflict-detection false; directive in the dhcpd.conf.
It is supported in EL6 or and dhcp >=3.1.0a1.
Since I am not going to get permission to switch to EL6 or dhcp 3.1 what are my options?
Background:
I have a DNS/DHCPD system which its conf files are generated automagically. Depending on which network a device is on the ip address will change. It is always required to have an A record for every device.
I see my only 2 possible options to be:
1, trick dhcpd into thinking that the records in dns are its, hence updatable.
2, backport the update-conflict-detection false logic into dhcp-3.0.5-23.el5_5.2
Any suggestions?
TIA

Set A records, and PTR's, for the addresses in your DHCP range. The client becomes "dhcp-0-101.example.com" for IP address 10.0.0.101 in the first DHCP range, and "dhcp-1-101" for IP address 10.0.1.101 in the second range.
There's a lot you can do with this, but hat is key.
The other useful trick is to set DHCP reservations: Reserve a particular IP address for a particular MAC address when it's plugged into a specific zone, so the same client always gets the same IP addresses in that zone and SSH and SSL keys remain consistent with that client host.
Any suggestions?

Thank you, but the issue I am tackling is that dhcpd is trying to validate a dhcid against the dns zone. And the records are either missing or invalid (depending on my efforts so far tonight).
Any suggestions?
