A. USER STARTUP (Remote and IRTF Observers)
The procedures for running spex for remote observing or at the IRTF are the same. Bigdog
and guidedog each run in a VNC session. Observers just need to connect to these sessions.
The step are:
1. Create your Guest Account.
Instruction for creating the guest account are located here:
2. Contact the IRTF staff for your VNC session number.
The IRTF staff will create and start the VNC session running the XUI (User Interface)
and DV (Data Viewer) for each instruments. They will give you the session numbers N, and
password so you can connect to the session. For example, if N=1, the connect to "stefan.ifa.hawaii.edu:1".
The password for the VNC session is obtained via the IRTF Staff (DayCrew or TO).
3. Start your vnc viewer
On the IRTF workstation, type of following command.
This example assumes you display number is 1 )
> vncviewer stefan.ifa.hawaii.edu:1
Remote user can connect to the VNC session using their own VNC client software.
Details on VNC operations for observers at the IRTF is found here: Using VNC with the IRTF
4. Login into the XUI
The XUI should present you with a login screen where you can idenity your guest account
via a pull down menu. Select your guest account and press the "Use Bigdog/Guiddog using
the above account" button. This will set you default data directory. We advise
not changing the part before "/scrs1/guidedog/guestXX/", but feel free to modify
the path after "guestXX/". After using spex, you would logout. Logging out runs a job
that will set data files to be owned by and read-only by 'guestXX'.
The pull down menu also has a 'guidedog' or 'bigdog' account selection. Choosing this will not change the saved data upon logout. The data will be own by the instrument account and be readable to all users.
See if the bigdog and guidedog VNC session are active using vnc -show
