The above is where the FTP process comes to a complete slow down.

I'm running an FTP server off my RedHat Linux 9 box (its the default FTP program that came with RedHat 9). When I am connecting over my home network, I get a directory listing instantaneously, however, when I am connecting over my schools T1 line, it takes nearly a full minute to get a directory listing. My DSL line is ~1290Kbps down and ~219Kbps (those are actual recorded values). Is this normal for this to be taking so long? Or is my line just too slow to run an adaquate FTP server.

Both the directory listing and when I'm using the Windows Explorer (built-in) FTP client, it takes nearly a full minute to "Calculate to time required to upload files." As well.

Thanx in Advance.
