Excellent instructions are provided here, a summary is provided below.
Login to the ssh server with your client.
Generate your key pair using the following command:
$ ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/home/jurn/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/jurn/.ssh/id_rsa Your public key has been saved in /home/jurn/.ssh/id_rsa.pub $ cd ~/.ssh $ cat id_rsa.pub >> authorized_keys $ chmod 600 authorized_keys
Don't use any passphrase
Log out of the server and go back to your local shell
$ cd $ mkdir .ssh
Copy the file id_rsa that was generated on the server into this directory. You can use sftp or scp for this.
$ cd .ssh $ chmod 600 id_rsa
You should now be able to login via ssh without having to prompt for a password.
In cygwin, your home is in the passwd file /etc/passwd, even if you set the $HOME environment variable
Check that the authorized_keys file on the server is not corrupted.
If you are having trouble you can use the -v option in ssh to give you some debugging info.
Lookup the man page for ssh if you are stuck.
