Introductory notes on computers and software

The main control interface during an observation is e-Remote Control, which communicates with the PC Field System (PCFS) machines at the observatories. All the computers at the observatories have names ending with their two-letter telescope ID:

  • Hb = Hobart 12m
  • Ke = Katherine
  • Yg = Yarragadee

There are four computers at each site that run the most important items of hardware or software. They are:

Type Function Computer Name Access with…
Hobart Katherine Yarragadee
PC Field System Linux PC that runs Field System software to control the antenna, DBBC and Mark5 pcfshb pcfske pcfsyg ssh, VNC (display 1)
Mark5 recorder A Linux PC inside the Mark5 recorder which runs dimino, a program the PCFS communicates with to control data recording mk5hb mk5ke mk5yg ssh
Timing PC Windows PC that monitors the H maser, the CNS-II GPS clock, shows the wind speed and direction, and runs HMI: a GUI for controlling and monitoring the antenna timehb timeke timeyg VNC display 0
DBBC A Windows PC in the DBBC which runs a server (and optionally a client) program to allow control and monitoring of the DBBC dbbchb dbbcke dbbcyg VNC display 0

Each of the above can be accessed either through a terminal via ssh or by starting up a VNC session. It is necessary to bring up the VNC sessions when setting up for an observation or when doing one of the regular ~2 hourly system checks. Given the slow network connection to Yarragadee it is not recommended to keep the VNC sessions up at other times.

VNC or terminal sessions can be started via the Application menu on ops2 in the top left of the desktop. e.g. for Yarragadee:

Applications -> AuScope Yarragadee -> VNC -> [choose the server]

VNC sessions can also be started up on the command line. e.g:

vncviewer -shared pcfshb:1
vncviewer -shared dbbcke:0

Screen night vision

In case somebody had turned on the night vision (orange screens), to unlock open a terminal on ops2 and type

redshift -x

To turn it on

redshift -O 3500

And turning screen brightness down helps the eyes too.
