One common suggestion for securing a secure shell connection on Linux is to change the port that ssh runs on.  But how exactly do you connect to a server on one of these non-standard ports?

Naturally, the syntax is different for each so here goes:

ssh

ssh -p 33432 [email protected]

Yes, ssh uses a lower case p command line argument. Just wait until we get to scp.

sftp

sftp -o "Port 33432" [email protected]

Of course sftp uses a plain English option parameter of “Port XXXX”

scp

scp -P 33432 /home/user/file.txt [email protected]:/home/user

And naturally scp uses a capital P

Gotta love consistency!
