RE: TCP Wrapper Question
I didn't mention that the client machines run on a windows [Active Directory] DNS/DHCP servers. The windows nameserver is 172.16.164.100, which is referenced in /etc/resolv.conf

Thing is when the machines names change, the servers can still look them up with proper details. [My laptop is on DHCP and generally gets a new IP every 48hrs, and I can still look this machine up both ways].
Thing is im not sure *where* my problem is. The machine can obviously connect to the DNS server and get the details, so why isn't tcpd doing it?
Thanks

DNS and DHCP on the same box, so that (possibly?) DHCP can update
DNS with device names? Otherwise, how do you map name to IP?
Another way would be to have the DHCP server to log MAC-IP-timestamp
tuples, load it into some tool (whether it be a DBMS, spreadsheet or
Python/Perl/etc list) and use that to derive what you need to know.
