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:
/usr/bin/Xtigervnc :1 -desktop mpvnc1 -auth /home/atcaobs/.Xauthority …
If VNC is not active then run (this is an alias)
Check it returns something like the following and has started on screen :1.
New 'X' desktop is bigrock:1
You should now be able to connect your VNC client to the server.
You should run the following applications. Note to get an xterm on mpvsi1 or mpvsi2, Use the
Telescope menu on the bottom right (
VLBI Utilities→mpvsi1). To get an xterm on bigrock, click the “Terminal” icon to the right of the Telescope menu.
The first desktop is for main observing. Run the following windows:
DAS control and monitoring
If the DAS GUI was not closed cleanly, a lock file will have been left in place. The terminal will report
Lockfile /var/lock/das_serial2.lock DOES exist
If this does happens, quit the DAS GUI. , delete the file above and restart
If a 2x 64 MHz recording will be run, 2 recorders are needed. Run a terminal on mpvsi2 in Workspage 5 and run another cdisko instance there. Do not run this by default, as it can confuse observers.
Start MoniCA from the Telescope menu (Observing→Monica) (then select Mopra!). Startup the following monitoring windows via the menu
Move the last 2 windows to workspace 1 (Top left button on the window with a downwards arrow and select
Send to…→Workspace 1
