How to change default vsftpd port (TCP port 21)?

vsftpd (Very Secute FTP Daemon) is used by Fedora, Ubuntu, RHEL and other Linux based distros.

Changing default can be a good ideia for security reasons.

Login to your server as root

Open vsftpd.conf file (by default /etc/vsftp/vsftpd.conf or /etc/vsftpd.conf)
# nano vsftpd.conf

Find line that read as follows
listen_port=21

Then, replace port 21 with new port (example 23)
listen_port=231

Save and Exite. Make sure that no other service is usign that port.

Restart vsftpd
# /etc/init.d/vsftpd restart
