FreeBSD/DHCP 3.0.3

Have an old dhcp server under FBSD 4.8R using dhcpd 3.0.1rc11 built from
ports, using the Netreg system. Its been working just fine since about
Feb of 2004.

Need to move everything to a new machine soon so moving to FBSD 6.0
and having some problems with dhcp.

With FBSD 6, I portsnap'd the ports tree then built dhcp from
there, no jail, no chroot.

Getting this error:

unable to create icmp socket: Operation not permitted
Jun 29 19:55:00 netreg dhcpd: Can't open /var/db/dhcpd.leases for append.

Ok so hunt around dhcp-users, freebsd lists and while I find a few things
nothing directly that seems to help.

So deinstall the port and get then build from sources.

Builds installs no prob.

But still getting the above error. More searching, reading docs, it still
appears that dhcp is running in a jail or chrooted.

So dhcpd 3.0.3 under Freebsd 6.

It starts ok.

# ps axu | grep dhcpd

Its running.

Snip /var/log/messages 2 mins later:

My lease file.

dhcpd did something to the lease file when it started as the time stamp on
it is the same as the time for the process.

/var/db perms:

# ls -ld db
drwxr-xr-x  8 root  wheel  512 Jun 29 20:09 db

I dont know where else to look on this and am a bit stumped and I'm
getting annoyed at all the messages from: Cron <operator at netreg>

Anyone give a guy a hand on this?
