I am developing a project and want to change the FTP port in order to integrate some module from my server and for security I want to use a different port for FTP. How can I change the FTP port.
If you are using pure-ftpd, then you can change the FTP port from pure-ftpd.conf. You find a parameter called bind address.
You need to simply change the port of you choice in bind address by replacing the default port 21.
