It is one I found on the internet and altered to fit my needs, as I said
it works on RC2 but now will not work on pre1.
basically the script is run by dhcp from dhcpd.conf, it checks a
kerberos keytab then runs nsupdate to first delete the pc's nameserver
record (if there is one) then adds it into to the required zone. The
script then checks to see if the record now exists.

So, it now listens on all interfaces?

Do you mean as in:
host -t A linpad.home.lan
Host linpad.home.lan not found: 3(NXDOMAIN)
host -t PTR 192.168.0.171
18.104.22.168.in-addr.arpa has no PTR record

Ah, what would be the correct Kerberos keys?, I am using one that I
created for a user I also created, as I said it works on RC2

This would be no problem if I only knew how to do this (hint hint) ;-)
Thanks for any help you can give
