[expert] hosts.deny and ftp

[Perry Ler]

anyone knows which application is controlling the hosts.deny? if i have an ip been throw into this file, which application shld i restart so that box from that ip can come into the server again? The only method i know is rebooting the machine but that is kind of stupid.     how do i get the proftpd to access connection? i have edited the xinetd and hosts.allow file but all failed to allow connection through. can someone help me on this?
