Mopra VLBI observing is run from a VNC session on bigrock:1. Note that the VNC session is only accessible from within the ATNF network or via VPN or ssh port forwarding. If you cannot connect your VNC client to this host, check the VNC session is running on screen :1. To do this log onto bigrock using the normal observer username and pasword and run
> ps aux | grep -i vnc
The output should be something like the following. You are need to check a VNC server (such as Xtightvnc) is running on screen :1. The output should be something like:
Xtightvnc :1 -desktop X -auth /home/atcaobs/.Xauthority -geometry 1600×1000 -depth 24 -rfbwait 120000 -rfbauth /home/atcaobs/.vnc/passwd -rfbport 5901 -fp /usr/X11R6/lib/X11/fonts/Type1/,/usr/X11R6/lib/X11/fonts/Speedo/,/usr/X11R6/lib/X11/fonts/misc/,/usr/X11R6/lib/X11/fonts/75dpi/,/usr/X11R6/lib/X11/fonts/100dpi/,/usr/share/fonts/X11/misc/,/usr/share/fonts/X11/Type1/,/usr/share/fonts/X11/75dpi/,/usr/share/fonts/X11/100dpi/ -co /etc/X11/rgb -alwaysshared
