I need to run SCP, SFTP and SSH in three different ports

Question

I need to run SCP, SFTP, and SSH in the same host but via three different ports; is there a way where we can configure SSHD in that manner? Thanks in advance.

Answer 1

You can do that by adding in

/etc/ssh/sshd_config

file the ports you want to use on the server: Example:

Port 22

Port 60000

Port 60001

And then on the client you can, for example:

$ scp -p 60000 ./file 192.168.1.2:/home/user/   ##adapt on your needs

in another terminal

$ ssh user@192.168.1.2   ##that's on port 22

and can run sftp

$ sftp -P 60001 user@192.168.1.2:/home/user/file  #transfer file to your pwd

That it.

Answer 2

The port that has full usual SSH on it will always also be usable for scp and SFTP. If that restriction is fine for you, you can of course start two additional SSH servers by passing other config files with other Port settings via -f. One of them will have the ForceCommand internal-sftp setting, the other one any of the solutions suggested here.

Answer 3

As a variant, you could configure SSH on any port that you want and make port-forwarding from three(for SSH, SCP and SFTP) different ports to this SSH port.
