Re: FTP connect

Scott,

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. I can't remember why, but if it can't find it, there will
be this 30 second delay.
