FTP Connect - 30 secs delay

["Leif Svalgaard" <leif@xxxxxxxx>]

I think, that FTP server code resolves it's own IP address via DNS, so even
if you do not use DNS on a client, it is still being used on a server side.

You may not be doing a DNS lookup on your AS/400's IP address... but as
soon as you connect the AS/400 is taking YOUR IP address and using DNS to
find out the name of your client.

I actually asked IBM if the FTP was doing a lookup on the client IP address
or name and the answer was a definitive "no". We had several customers
experience this same problem. However, the FTP server does do a lookup on
the AS/400 name.

The IBM AS/400 FTP server does a reverse lookup on its own domain name. If
DNS is configured to be searched first it will take 30 seconds to fail over
on the search and give you the user prompt

I'm still confused.
I have two PCs. They are both configured identically
(disable DNS).

One can FTP to several AS/400s with no 30 sec delay.
None of these AS/400 know anything about my PC.
I'm connecting over the internet and my IP address
changes every time.

The other is only connected (through a local 3COM router) 
to one AS/400 and has the 30 sec delay.
