(OT) Very Slow SCO Openserver FTP Openserver logins

[Bob Rasmussen]

One reason for slow logins (generically speaking) is the the server is 
making a lengthy attempt, and failing, to do reverse DNS; that is, trying 
to verify the client's IP address. You could test whether this is the case 
by adding the client's IP address to /etc/hosts.

FWIW.
