how to log in to a remote pc with public key without having that user on the machine used to log in from?

  • 772

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 [email protected] 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?

ubuntu ssh remote-access

  1. 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:

    ssh [email protected]

    without being asked for a password (unless you have a key that needs to be unlocked).

    Your private key should be in ~/.ssh/id_rsa. Make sure the right are set properly:

    chmod 700 ~/.ssh
chmod 600 ~/.ssh/id_rsa

    Your public should be at ~/.ssh/authorized_keys and have the following rights applied:

    chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

    Finally, go and check in /etc/ssh/sshd_config if keys are allowed to be used.

    try on your local machine

    ssh-copy-id [email protected]

    if you didnt create your key then before ssh-copy-id you must execute

    ssh-keygen

    then

    ssh [email protected]
