I keep running into this problem where people want static DHCP assignments, and their own hostname, but don't want to wait on OPS to give it to them. So, one would think that ddns is perfect for this, and in a way I agree, but it seems to cause some issues with caching, the jnl files, and hand editing the zone files.
So, here are a few commands I found that help alleviate some of the issues:
Hand editing the zone file:
$ rndc freeze zonefile
Edit the zone file making sure to update the serial number
$ rndc thaw zonefile
$ rndc reload
I'm looking at moving to a powerdns setup with a mysql backend, but I'm still looking for a nice web interface to handle both DNS and DHCP entries that will allow regular users to request a hostname/IP given their MAC.
