HOWTO: FIX: proftpd delay when connecting

Hi all,

Ran across this and hope it helps someone as I couldn't find anything
when I looked..

If you are running proftpd and you get a timeout prior to it asking
for the username, you are running into one of two problems:

1. proftpd is attempting reverse DNS lookups, and timing out
2. proftpd is attempting IdentLookups, and timing out.

Most people will say #1 is the cause, but for me, it was #2. Here's
how to fix one or both... in your /usr/local/etc/proftpd.conf, add the
following line(s):

UseReverseDNS off
IdentLookups off

These options can exist in the Global area, or under a virtual host.

Here's more info on each (from proftpd's website):

Cheers.
