I would like to be able to use ssh key to log into my web server via ssh and disable password authentication completely (to eliminate brute force from malicious ip addresses). So I am reading the documentation:
Now it instructs to do the following:
chmod 700 ~/.ssh
ssh-keygen -t rsa
Here's the problem with running ssh-keygen. I already did that in order to generate keys to connect to my github account. So my .ssh directory already looks like this:
~/.ssh$ ls -l
-rw------- 1 viggy viggy 1766 Sep 5 20:36 id_rsa
-rw-r--r-- 1 viggy viggy 403 Sep 5 20:36 id_rsa.pub
-rw-r--r-- 1 viggy viggy 4422 Dec 22 11:45 known_hosts
Will running that command again overwrite the id_rsa files? Is there a better way to store both keys?
My ultimate goal here is to not overwrite my git keys, yet generate a ssh public and private key so that I can copy the public key to ~/.ssh/authorized_keys on my web server.
