    The machine wide settings are in /etc/ssh/ssh_config
    if you want to change the behaviour of ssh for yourself
    copy this file to $HOME/.ssh/ssh_config and change

        ForwardX11 no

    to

        ForwardX11 yes

    If you want to change it permanently only for a specific domain insert

        Host *.yourdomain.org
          ForwardX11 yes

    Your privat ssh_config in $HOME/.ssh/ will overwrite the settings
    in /etc/ssh/ssh_config as long as the SSH server on the remote machine
    allows it.
