This sounds like a dns reverse-lookup issue. AIX ftp and telnet, as far
as I can tell, default to doing a reverse lookup on your IP address to
get the host name and then a normal lookup to see if the original IP
address is returned.

I've run into this when the reverse lookup data isn't maintained
properly.

Subject: offtopic: AIX FTP/TELNET question

Sorry for asking this on the ADSM list but I know a lot of folks using
AIX
can help me with this. I'm having an FTP and Telnet issue and as far as
I
can tell it is not AIX related.



I am trying to access 2 of my TSM servers in a fire walled off area. FTP
and
telnet login screens were typically sub second screens but now are
taking
right around 75 seconds when using reflections. Command line ftp fails
so my
jobs are not working. Command line FTP eventually comes up and says
connected but then it also says the connection is closed by the remote
host.
This happens right at 60 seconds. Reflections FTP takes 75 seconds but
allows me to log in and transfer files. Dos command line telnet also
takes
75 seconds but works. Reflections Telnet work the same way.



This phenomenon started last week and, as typically happens, I'm told
it's
my problem and nothing network related. Just so I don't go down and rip
someone's head off when I shouldn't, would some please tell me I'm wrong
and
where to fix this if it actually is on my end? Is it possible it is
having a
hard time trying to find a route or is this a setting on my side that
can be
changed I'm not aware of?



Thanks,
