Presenting the “Grandma Mode”

Do you also have some relatives that always ask for “family support”: When you come to their house, you find a totally f***ed up Windows XP machine with tons of spyware and you’ll get to hear “I did not do anything”. The worst part of it: While you do the work, they keep talking at you.

Well it can be easier. Just configure your DSL router to forward inbound traffic on port 5500 to your desktop machine and get a nice DynDNS hostname. Then remaster any LessLinux Search and Rescue CD to include one boot entry that does not disable earlynet and add the cheatcode


In case of emergency tell your grandma to boot the CD with the respective entry. The earlynet script requests an IP address on all wired interfaces and instead of starting a local Xserver Xvnc is started and a reverse connection to your host is made where a listening VNC viewer must be running.

There is one drawback: the data is transmitted unencrypted, which might be an issue with sensitive data. You might however use this first VNC connection to build up a SSH tunnel between two hosts.

The background of this feature: I got some customers quite far away from here. With this cheatcode I can help them no matter where they are – no special configuration of their router required. This feature also will work over WLAN soon. I just introduced some cheatcodes to attach to a wireless network while startup. Those are not tested yet, so please be patient for a few more days.

Should work in all builds higher than 20100701-000000.

    Hi! Since Version 2.28 Empathy is able to establish a VNC-Session through NATs – without configuring any router – when both user are connected via Xmpp (maybe other protocols as well).
