Pablock-sslDet er enkelt! Bare du kan det. Det kan han som har laget denne siden: http://www.csua.berkeley.edu/~ranga/notes/ssh_nopass.html

Her følger oppskriften (på engelsk). Spør en voksen hvis du ikke kan engelsk:

  1. On the client run the following commands: 
    $ mkdir -p $HOME/.ssh
$ chmod 0700 $HOME/.ssh
$ ssh-keygen -t dsa -f $HOME/.ssh/id_dsa -P ''

    This should result in two files, $HOME/.ssh/id_dsa (private key) and $HOME/.ssh/id_dsa.pub (public key).

  2. Copy $HOME/.ssh/id_dsa.pub to the server.
  3. On the server run the following commands: 
    $ cat id_dsa.pub >> $HOME/.ssh/authorized_keys2
$ chmod 0600 $HOME/.ssh/authorized_keys2

    Depending on the version of OpenSSH the following commands may also be required:

    $ cat id_dsa.pub >> $HOME/.ssh/authorized_keys
$ chmod 0600 $HOME/.ssh/authorized_keys

    An alternative is to create a link from authorized_keys2 to authorized_keys:

    $ cd $HOME/.ssh && ln -s authorized_keys2 authorized_keys
  4. On the client test the results by ssh’ing to the server: 
    $ ssh -i $HOME/.ssh/id_dsa server
  5. (Optional) Add the following $HOME/.ssh/config on the client: 
    Host server
         IdentityFile ~/.ssh/id_dsa

    This allows ssh access to the server without having to specify the path to the id_dsa file as an argument to ssh each time.
