Hi all,

I have used VNC for quite a long time to support other people having any
kind of PC troubles.

Most annoying thing about VNC: if VNC server is behind a DSL router, you
have to setup forwarding port 5900 to an internal IP. If external IP
address is dynamic, you also have to setup DynDNS. For non-techie people
this is quite complicated stuff...

Are there any alternative desktop sharing programs that work through
routers and do not need sophisticated router configuration?

Regards
Gerhard

You may want to look at Hamachi (http://www.hamachi.cc/).

you can use VNC in the other direction too.

on your PC you start the VNC viewer in listen mode, and the other user
initiates the connection via "add new client".

Please keep in mind that VNC connections are not encrypted and can be
sniffed easily. The better solution would be to tunnel VNC through a
SSH connection.


Viele Grüße,

That's what firewalls do for us, make us secure. :-)

UltraVNC (freeware) can encrypt using a plugin (freeware) from their
web page. Far easier than configuring an SSH tunnel using Putty
(freeware).
