Installation FTP program on dedicated linux

[dxflw]

Hello guys.
I use dedicated software and i want to create a private ftp.
I ask my company about and they say:
Your server is now using proftpd so make sure that install an other
program and don't use port 21 since this will give conflicts

I have no idea about linux.
How do i install another program and use other port?

:confused:

You have a dedicated server with SSH access, so use SFTP now. No need to install any program. Use WinSCP and connect using SFTP protocol.

About changing port, then you need to edit your sshd_config file and change the port number.

How i do that all?I have no idea:(
Any tutorial?

For SFTP: Install WinSCP, and login using SFTP protocol with your same SSH user details.

For Port number: Open ssh config file with this command

vi /etc/ssh/sshd_config

Locate the "Port" directive. Change the default SSH port. Restart SSH and connect via Putty using the new port address. Don't forget the port number. To restart ssh server, use this command:-

/etc/rc.d/init.d/sshd restart

The WinSCP is a program for my PC on home?(other way how do i install this on the server?I'm Using parallels Plesk Panel)
And if you say "SSH user details" you mean the admin details?
