Starting a second session using the VNCserver

swamprat · 03-23-2007, 09:56 PM

Greetings all,

I'm using the following command to start a TightVnc session on my Suse 9.2 box.

vncserver -geometry 800x600 -depth 24

This works just fine and the person on the Windows-XP machine can get to the Linux desk top.

Now another user wants to gain access to the same Linux box (now 2 users).

Would the same command as above be used to start a second VNCserver session so a second user could get in?
And if so what would the second person have to do differently to get into the Linux box from his Windows-XP box after he starts TightVNC?

I'm not in my office now so I can't try this out, I just have to call this person and advise him what to do.

Thank you.

Sorry, I guess what I need to know is this, does either user have to specify some sort of a session number on their windows machine.

I use the following to start 2 VNC servers on one of my boxes. From a windows box I use 192.168.2.11:1 and 192.168.2.11:2 for the connections strings for the tightVNC client:

Code:

#!/bin/sh
#

unset VNCSERVERARGS
VNCSERVERS="1:steve 2:oracle"
VNCSERVERARGS[1]="-geometry 1280x960"
VNCSERVERARGS[2]="-geometry 1280x960"

start() {
  echo -n $"Starting VNC server: "
  ulimit -S -c 0 >/dev/null 2>&1

  if [ ! -d /tmp/.X11-unix ]
  then
    mkdir -m 1777 /tmp/.X11-unix || :
  fi
  for display in ${VNCSERVERS}
  do
    echo -n "${display} "
    unset BASH_ENV ENV
    DISP="${display%%:*}"
    export USER="${display##*:}"
    export VNCUSERARGS="${VNCSERVERARGS[${DISP}]}"
    su - ${USER} -c "cd ~${USER} && [ -f .vnc/passwd ] && vncserver :${DISP} ${VNCUSERARGS}"
  done
}

stop() {
  echo -n $"Shutting down VNC server: "
  for display in ${VNCSERVERS}
  do
    echo -n "${display} "
    unset BASH_ENV ENV
    export USER="${display##*:}"
    su ${USER} -c "vncserver -kill :${display%%:*}" >/dev/null 2>&1
  done
  echo "Done."
}

# See how we were called.
case "$1" in
  start)
    start
    ;;
  stop)
    stop
    ;;
  *)
    echo $"Usage: $0 {start|stop}"
    exit 1
esac

Hope that helps...

Thanks for your reply and I'm sorry I haven't replied earlier.

I guess this is some sort of script, "C" language?

Anyway I'm a newbie and this doens't make to much scense to me at this time. I'm going to have a friend look at this and explain it to me.

But, isn't there a straight command to use which I could enter one at a time?

Thanks again

It's a shell script (bash syntax, in this case) that gets run when the server boots so that I don't have to manually start the vncserver.

You can manually login as the other user and run the same command as you did to get it running for yourself - but that's going to get annoying pretty quickly.
