Looking for a one step solution to appending my SSH public key to a server's authorized_keys?
To get my public key onto a server I normal copy the contents of my public key, then SSH into the server, then I run vi .ssh/authorized_keys, then paste my key into the file and save.
There has got to be an easier, one step way using SCP or something like that. Of course I want to append my key to authorized_keys, not overwrite it and the permissions of authorized_keys needs to remain at 600
You can also try this one liner:
cat ~/.ssh/id_rsa.pub | ssh user@remote-system 'umask 077; cat >>.ssh/authorized_keys'
I would suggest looking into the ssh-copy-id tool, for example:
ssh-copy-id -i .ssh/id_rsa [email protected]
