When I try to do a "yum update" against ftp.ydl.net, I get

	421 There are too many connections from your Internet Address.

Regular ftp (via wget) works just fine for the same file...

Clues?

I've gotten no reply from <support@ydl.net> so far (April 5th).

Are there any other YDL.net/enhanced members on the list that can
try this and report their results?

Thanks!
