Wow was getting ssh logins using RSA key pairs a real pain in the butt. I suppose if everything had been standard Ubuntu things might have worked out of the box... maybe.
In order for me to use the Bazaar Eclipse plugin I needed to setup ssh to my server to not require a password. This is because for some reason, the plugin can't handle any user interface type stuff with ssh. Sigh.
So I did the basics first.
I ran the following to setup my key pair (I typed in a passphrase when it asked, to make it as secure as possible)
ssh-keygen -t rsa -b 2048
Then to copy it to my home directory on my server.
ssh-copy-id suttonca@myservernamehere
But I still was having issues. It was asking me for a password even after I'd unlocked my RSA key. So I checked /var/log/auth.log on the remote server and found some errors like the following:
Authentication refused: bad ownership or modes for directory /home/suttonca/.ssh
I had to run the following commands to setup the permissions properly before the solution worked.
chmod go-w ~/
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
All that remained was to ensure that everytime I logged in that I was asked to unlock my key. In KDE all I had to do was run the following:
