First run ssh-keygen to create a key on $tower
You must replace $tower with the actual name of your tower pc.
You must replace $laptop with the actual name of your laptop OR it's IP
address

First you need to generate a key!  See my previous comments...

"man ssh-keygen" if you don't understand how to generate a key or can't
find a suitable tutorial on the internet (why reinvent the wheel?).


Notes: if you use the ssh or scp command without specifying a user, the
command assumes you mean run as the current user. i.e. if you are logged
in as "brian" @tower and "scp text.txt laptop:/$somewhere", the command
run is the equivalent of "scp text.txt brian at laptop:/$somewhere" (so you
better have a user with the same name on $laptop).


When you've run ssh-keygen on $tower you will have a directory created
in ~ called ~/.ssh

typical contents on $tower:/home/brian/.ssh is:-
authorized_keys   config       id_rsa.pub   id_rsa            known_hosts

typical contents on $laptop:/home/brian/.ssh when you've installed ssh
and run ssh-copy-id on $tower:-
known_hosts





Kind regards
