Pure-FTP
1) Edit /etc/pure-ftpd.conf and look for the following line:
Bind <addr> <port>
Where <addr> is a publically routable IP. The default example, 127.0.0.1, will cause the socket to bind locally but then this connection won’t serve externally. <port> is the new port you wish to put the service on.
2) If necessary, add the new FTP port to your server’s firewall
3) Edit /etc/chkserv.d/ftpd and change the port, which is the first comma-separated entry to the right of ‘=’ on the line in the file, to match the port you put the service on.
Finally:
/etc/init.d/pure-ftpd restart
/etc/init.d/cpanel restart (restarts tailwatchd/chkservd)
