Adding a Second SSH Key to a Remote Host

I always find that I run into some kind of problem whenever I try to add a new client computer to have automatic passwordless key access. So I decided to clearly document each step to adding a new client computer.
1. New Local Client
ssh-keygen # eval `ssh-agent -s` ssh-add # run the eval command above first if ssh-add fails
Copy the .pub file it saved on the new client over to the old local client.
2. Old Local Client (that has ssh access already)
scp ~/.ssh/id_rsa.pub korey@koreyhinton.com:~/.ssh/uploaded.pub
3. Remote Server
ssh korey@koreyhinton.com # create a backup cp ~/.ssh/authorized_keys ~/.ssh/backup # append key cat ~/.ssh/uploaded.pub >> ~/.ssh/authorized_keys
Now you should be able to ssh from the new local client to the remote server.
