BIND8, BIND9 and INETD services on AIX: OK OK OK OK

[alberto.colosi at sistinf.it]

Ya, exact!. I know so well this kind of problems but I don't know why I
haven't thinked that the reverse lookup was for the client who is
connecting and not the HOST (the AIX machine).

Thanks to have waked me up.

Ya, have reverse lookup and with a     nslookup - <ip-of-nameserver>
work FORWARD and REVERSE lookups.

Sounds to me like a reverse DNS issue.  When you connect to a unix
system via telnet, ftp, etc..., the server makes a log entry about that
fact.  By default, most servers will perform a reverse lookup on the
source IP address of the connection, to be able to make log entries in
terms of hostnames (instead of just IP addresses).


Make sure that both of your servers are authoritative for the
in-addr.arap zones (the "reverse" zones) that are associated with the IP
address space on your network.  The most likely problem is that you do
not have these zones loaded on your NT system.


Thanks,


Dave...
