Remove FTP Login Delay With Proftpd
August 16th, 2007 by vickyI have been noticing a very annoying delay when trying to log in via FTP on servers where I use proftpd. Everything works, but when I try to connect, 5 - 10 seconds pass by before I’m prompted for my login credentials. After long hour of searching on the internet I found a solution.
All you need to do is edit the config file which should be /etc/proftpd/proftpd.conf and place this line within <global> section:
IdentLookups Off
That should remove the delay and your ftp connection will be initialized very quickly.

I was having the same problems with huge delays when logging in, found this through Google and it sorted out the problem very nicely. Not many servers even have identd running these days, anyway.

The problem is not on the IdentLookup but in the mod_delay that is on by default.
This module gives a 10 seconds delay before prompting for login, as written in the Doc “Delay engine reduces impact of the so-called Timing Attack described in http://security.lss.hr/index.php?page=details&ID=LSS-2004-10-02“
