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. This post is also a reminder for me to find a quick config to use.
Example
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 niklas@example.com. 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
Copy specific key with ssh-copy-id
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,
Niklas
