# This script is intended to help other users.
# It launches an SSH-Tunnel to necoro.eu and makes it forward connections to port 5500
# (yes! this does not need any firewall hackering)
#
# Ideally used with an VNC-Exe generated by http://www.heise.de/netze/tools/fernwartung
#
# Needs locally: net-misc/ssvnc
# (I couldn't get it to work with any other vncviewer)
