Tried to implement DDNS using SUSE 7.3 without success. Who can help?

[Kevin Darcy]

Look at the logs. If a Dynamic Update is being attempted and failing,
then there should be a "denied update" log message from named and
possibly something from the DHCP server as well. If a Dynamic Update is
not even being attempted, then this is presumably a DHCP server problem.
You should probably ask a DHCP list about that.

P.S. Why did you create a TSIG key and then not use it?
