If you are looking to change the Ftp port on your server from 21 to a non-standard port say 2121, you need tweak the ‘bind’ option in the Ftp configuration file.  On a cPanel server with pure-ftp as a Ftp server, you need to edit the pure-ftpd.conf file

# pico /etc/pure-ftpd.conf

Search for the line:

# Bind 127.0.0.1,21

and add the following line below it

Bind *,2121

where, 2121 is the new port you want the Ftp server to listen to.

Save the Ftp configuration and restart the ftp service.

# service pure-ftpd restart

Using the netstat command you can check if the new port is in ‘LISTEN’ state

# netstat -al | grep 2121

If your server is behind a firewall, you will have to open the new Ftp port in the allowed list. For example, if you have CSF firewall installed on your server, edit the configuration at

# pico /etc/csf/csf.conf

and replace port 21 with 2121 in the TCP_IN. Save the file and restart the csf firewall

# csf -r
