I want to log in on a remote pc, example 10.10.10.5, from my local machine, called umar. the user on the remote machine is 'coolapp', so i want to pretty much do: ssh firstname.lastname@example.org and not enter a password but log in with public key. the problem is that on my local machine, i dont have a user 'coolapp'. how can i log in on the remote machine without having to first create a user 'coolapp' on my local machine and generating the ssh keys for it?
try on your local machine
if you didnt create your key then before
You are mixing a few things up here. You do not need to have the same user name across systems to be able to log in on remote systems.
Make sure to put your key on the remote server (public part), and on your local machine (private part) (and check the rights). Then you should be able to login with:
without being asked for a password (unless you have a key that needs to be unlocked).
Your private key should be in
Your public should be at
Finally, go and check in
