Granting SVN access to external users

Description: http://svnbook.red-bean.com/en/1.1/ch06s03.html

  1. Get the public ssh key of the user.
  2. Append the public ssh key to /home/svn/.ssh/authorized_keys.
  3. Insert
    command="svnserve -r /home/svn/repos -t --tunnel-user=<user>",no-port-forwarding,no-agent-forwarding,no-X11-forwarding,no-pty
    before the key. Now the user can only execute the SVN command, and any other command will be ignored.
