+====== SSH tunnels ======
+For the Mac and Linux commandline ssh client, setting up a tunnel is usually a matter of using the option \\
+''%%-L local_port:remote_machine:remote_port%%'', e.g. ''%%-L 3389:windows machine:3389%%'' \\
+for forwarding a Windows remote desktop. More detail can be found in the [[vnc|vnc ssh tuning pages]].
+See [[linux:putty]] for instructions about setting up a tunnel with ''%%putty%%'' (Windows, linux ssh client).
+====== SSH client software ======
+Linux and macOS come with a commandline client for ssh.
+For Windows, the recommended client is [[linux:putty]]

+This will place your keys in your home directory on the remote server. After that we will login on the remote server using ssh or telnet the conventional way... with a password.
-====== SFTP and SCP file access ======
+When you are logged in you should create a .ssh directory, and inside the .ssh/ directory create an authorized_keys and an authorized_keys2 file and add the keys to the files. Make sure the files are not readable for other users/groups. chmod 600 authorized_keys* does the trick.
-====== SSH tunnels ======
-For the Mac and Linux commandline ssh client, setting up a tunnel is usually a matter of using the option \\
-''%%-L local_port:remote_machine:remote_port%%'', e.g. ''%%-L 3389:windows machine:3389%%'' \\

-See [[linux:putty]] for instructions about setting up a tunnel with ''%%putty%%'' (Windows, linux ssh client).
+Placing the key for version 2 works as follows:
-====== SSH client software ======
-Linux and macOS come with a commandline client for ssh.
+  $ cd .ssh
-For Windows, the recommended client is [[linux:putty]]
+  $ touch authorized_keys2
+  $ chmod 600 authorized_keys2
+  $ cat ../id_dsa.pub >> authorized_keys2
+  $ rm ../id_dsa.pub
+From now on you can login from client yyyy to server zzzz without having to specify a password.
+====== SFTP and SCP file access ======
