Since I don’t do this often enough to remember – here’s the procedure summarized (for Linux and OS/X, on Windows use putty):
me@here is username me at ip/hostname here
user@there is username user at ip/hostname there
me@here$ cd me@here$ ssh-keygen -t rsa
press return a few times, don’t enter passphrase. This will create a public/private RSA key pair in your .ssh folder
Create the .ssh directory on the remote device (if it doesn’t already exist), and then add the local public rsa key to it’s list of authorized keys:
me@here$ ssh user@there mkdir -p .ssh user@there's password: me@here$ cat .ssh/id_rsa.pub | ssh user@there 'cat >> .ssh/authorized_keys' user@there's password:
the next time you ssh user@there you will not be prompted for a password.
Note that some systems might require the following:
- Placing the public key in .ssh/authorized_keys2
- Changing permissions of .ssh to 700
-
Changing permissions of .ssh/authorized_keys2 to 640
git ssh keys on Windows ∞
If you install git on Windows, the ssh key will be in directory
c:Program Files (x86)Git.ssh
If you have linux tools for windows installed, the .ssh folder it will use will be in your user directory
