ssh login via shared key
Since I only need to set this up the first time I get a new PC/server online, I figured I might as well document it here to make it easier to remember.
Very briefly, we're creating a new key with ssh-keygen. (Don't run this if you have an existing key you want to use). We're then copying the public portion of the key to [server]'s authorized_keys, which will allow us to login without a password from now on. Many assumptions are made here, so if you run into problems, google "ssh key login" for more info.
Use wisely.
ssh-keygen
cat ~/.ssh/id_rsa.pub | ssh [server] 'mkdir -p .ssh ; cat >> .ssh/authorized_keys'
