Next, run SSHKeychain, and go into it’s preferences. This nifty little tool will act as a gateway to Mac OS X’s keychain. The next step is to get this keychain to keep our SSH keys as well.įirst, download and install SSHKeychain.

While this certainly is a nice improvement, it still isn’t that easy to use.įortunately, Mac OS X already has a great feature for managing your keys: the keychain. Having verified that the previous steps worked, we’ve created a situation where instead of all kinds of different passwords, you have to type in a generic passphrase for every new connection. You should be prompted for your passphrase and it should work :) Integrating into Mac OS X Test it by typing in (on the client):Ĭlient:~ user$ ssh -o PreferredAuthentications=publickey Now we have basic public key authentication working. Next, we SSH to the server, and add our key to the list of authorized mkdir ~/.ssh #if it doesn't chmod 700 cat ~/id_rsa.pub > chmod 600 rm ~/id_rsa.pub
Any other UNIX running OpenSSH will do fine.įirst, we copy the key from your Mac to the server using SCP:Ĭlient:~ user$ scp ~/.ssh/id_rsa.pub will put the key in your homedir. In my example, the server is a Linux system. Needless to say, the private key (~/.ssh/id_rsa) should be kept private at all times, and the public key (~/.ssh/id_rsa.pub) is meant for distribution. This will generate a public/private key pair. Generating keys for the client (your Mac)Ĭlient:~ user$ mkdir ~/.ssh # if it doesn't existĬlient:~ user$ ssh-keygen -q -f ~/.ssh/id_rsa -t rsaĮnter passphrase (empty for no passphrase): … Since Mac OS X is just like any other UNIX, this should be basic knowledge.

If you already know how to do this, and are just interested in the Mac OS X specific part, skip to the end :) Key generation and exchange
What I am going to explain, is how to get it to work seamlessly on Mac OS X.įirst, I’m going to explain how to get the authentication to work in a client/server configuration. If you want to know (and you should), just read Dave Aaldering’s SSH with Keys HOWTO. I’m not going to explain here what public key authentication is and why you would want to use it for increased security.
For those of you who are as lazy as I am, and don’t want to type in and remember all kinds of different passwords for different hosts, it is the solution. One of OpenSSH’s great features is ssh public key authentication. 28 May, 2006 SSH public key authentication on Mac OS X
