It makes good security sense to change the ssh port on servers that are Internet accessable. To take advantage of this using ssh is quite straight forward as their is a parameter -p to support this eg:
ssh -p 3432 firstname.lastname@example.org
Unfortunately the same is not true for sftp (secure file transfer). To achieve the same result with sftp we need to use specify an option of “Port 3432” eg:
sftp -o “Port 3432” email@example.com
Once done log it as you would normally.
