I had to set up an Ubuntu machine a couple weeks back and set up a fresh git server at work. To get rid of the authentication every single push and pull I set up ssh keys to authenticate that way.
With the following ssh-config the ssh client will open a ssh connection with only typing
ssh example. The user that is used then is
niklas. Otherwise you would have to write
ssh -i ~/.ssh/example.key firstname.lastname@example.org. If this is a connection you have to connect to more often this is can be a waste of effort. Just simply open your ssh-config with
nano ~/.ssh/config and use the following config:
Host example HostName example.com User niklas IdentityFile ~/.ssh/example.key
$ ssh-copy-id -i path/to/key user@host
This command will easily transfer your public key to the
authorized_keys on your server.
Thanks for your time,
