[TriLUG] question 1: RH 7.1 FTP access SLOW

> I am running RH 7.1 connected to a cable modem and I just enabled ftp through the firewall.  I have plenty of bandwidth but the FTP server running on the box seems very sssslllllooooooowwwwwwww... It takes forever to respond to the initial FTP request (but transfers files quickly once connected).

This sounds like tcpwrappers attempting (and eventually failing) to do
a reverse DNS lookup for logging.

IIRC, 7.1 had already switched over to xinetd, so IIRC you should
be able to edit /etc/xinetd.d/wu-ftpd and edit the 2 log_on_* lines
to drop the USERID

This is all from a distant haze of a memory, though, but I'm sure others
will correct me :)
