I just set up one of my old computers up in the corner of the living room so that there’s nothing but the bare necessities there. I SSH into it and do my stuff and then get out. It’s a lot of fun, really. While setting up SSH, I discovered that you could login to that SSH server without using a password if you used a pair of keys to handle the login. I’ve already been using Seahorse for a while now to handle my GPG keys and I noticed it could create a pair of SSH keys too. So I went through the process and it was super simple. All I had to do was:
- Go to Key » Create New Key…
- Choose SSH key
- Enter a description and go to the next step
- Enter a passphrase twice
- Allow it to set up the other computer by supplying my login details
That was all, and now I have paired-key authentication and don’t have to enter the password every time I log in to that computer. Hurray!
