I have a server with Debian 6, I installed the ftp service (ProFtp) but everytime I try to connect to my server first tries and get refused like 5 times (using different clients, but most of all filezilla) , I have no idea why is this, any missing configuration or delay or something.

Any idea of why is this? how can I make my conection faster and dont try many times until get connected?

the server has enough memory.

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

What do you see in the logs for the failed connection attempts? – Ladadadada Jul 4 '12 at 15:59
yea, the problem is that it only says "conection refused by the server" – jpganz18 Jul 4 '12 at 16:15

My guess is reverse DNS. See here and here.

Edit /etc/proftpd.conf and change the directives:

UseReverseDNS on
IdentLookups on


UseReverseDNS off
IdentLookups off
