Setup Password-less SSH Login

I hate having to login to remote machines. Since SSH can be configured with public/private keys, I think it makes sense to use them. Here is a very simple way to get my public key onto the remote server

  1. Create remote user.
    • If you are going to log in with a different user, then you’ll need to create a local account.
    • This command will prompt you for details about the new user. Just follow the prompts.
    • Replace remote-user with the name of the user you will use to connect to the remote machine.
       user@local:~$ sudo adduser remote-user
  2. Generate an SSH key for the new remote user.
    • This setups a passwordless key.
       user@local:~$ su - remoteuser remoteuser@local:~$ ssh-keygen -t rsa -P ""
  3. Copy public key to remote machine.
     remoteuser@local:~$ ssh-copy-id -i $HOME/.ssh/ remoteuser@remotemachine
