Here is the script I use for viewing what's going on my secondary machine,
it's based on the script by x11vnc's author Karl Runge and requieres x11vnc
to be installed on the remote machine:
#!/bin/sh
#--------------------------------------------------------------------------------
# usage: rx <host>:<xdisplay>
# e.g.: rx snoopy.peanuts.com:0
#SCALE='-scale 9/10'
OPTIONS="$SCALE -localhost -norc -notruecolor"
host=`echo $1 | awk -F: '{print $1}'`
disp=`echo $1 | awk -F: '{print $2}'`
if [ "x$disp" = "x" ]; then disp=0; fi
$HOME/.vnc/vnclog -mouse"
cmd="x11vnc -display :$disp -nap -o $HOME/.vnc/vnclog $OPTIONS"
ssh -f -c blowfish -L 5900:localhost:5900 $host "$cmd"
sleep 4
vncviewer localhost:0
#--------------------------------------------------------------------------------
Note your session is encrypted via ssh and can't be hijacked easily. Next you
can add extra security with pub keys.
What you want however is SCALE - simply uncomment and provide a fraction.
Works nice here. It's done serverside, too, so you can use any vnc client.
I haven't tried connecting from 2 machines simultaneosly tho. Would require
some more hacking, I guess.
