Just a quick note about sftp.
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.
