Running Spex as a Second Remote User

1.1 Requirements

These instructions assume that the single user instructions have been read.

As a prerequisite, you should create a guest user account for your run.

1.2. How to run spex as a second remote user

1. Allow IRTF computer to make Xwindow connection to your Xserver. Use the xhost command, for example "xhost +" allows access to everyone.

2. Starting DV and the XUI for Bigdog
   1. Starting DV on boltzmann
      • ssh to boltzmann:
        % ssh boltzmann.ifa.hawaii.edu -l guestXX

      • Give the command to start DV:
        % dv

      • If you are using 32-bit true color, you must start DV like this:
        % dv -T

   2. Starting the XUI on bigdog
      • ssh to bigdog:
        % ssh bigdog.ifa.hawaii.edu -l guestXX

      • Give the command to start the xui:
        % bigdogxui

   3. Verify the dv and xui setups
      • The first instance of dv executed on boltzmann will use the default port 30123. Any xui sending data to this dv needs to have port 30123 specified on the setup page.

      • Verify that dv is actually using port 30123 by checking the dv setup tab. It should state "Dv socket port is 30123" at the top of the tab.

      • Verify that the xui is sending the data to the dv above. On the setup tab, make sure that dv2 is set up properly:
        • dv2.enable is checked
        • dv2.hostname is set to boltzmann (the workstation running dv)
        • dv2.port is 30123

      • As a reference, here is the correct dv1 set up:
        • dv1.enable is checked
        • dv1.hostname is set to localhost
        • dv1.port is 30124

3. Starting DV and the XUI for Guidedog
   1. Starting DV on boltzmann
      • ssh to boltzmann:
        % ssh boltzmann.ifa.hawaii.edu -l guestXX

      • Give the command to start DV:
        % dv -p 30124

      • If you are using 32-bit true color, you must start DV like this:
        % dv -T -p 30124

   2. Starting the XUI on Guidedog
      • ssh to guidedog:
        % ssh guidedog.ifa.hawaii.edu -l guestXX

      • Give the command to start the xui:
        % guidedogxui

   3. Verify the dv and xui setups
      • The second instance of dv executed on boltzmann will use the specified port 30123. Any xui sending data to this dv needs to have port 30124 specified on the setup page.

      • Verify that dv is actually using port 30124 by checking the dv setup tab. It should state "Dv socket port is 30124" at the top of the tab.

      • Verify that the xui is sending the data to the dv above. On the setup tab, make sure that dv2 is set up properly:
        • dv2.enable is checked
        • dv2.hostname is set to boltzmann (the workstation running dv)
        • dv2.port is 30124

      • As a reference, here is the correct dv1 set up:
        • dv1.enable is checked
        • dv1.hostname is set to localhost
        • dv1.port is 30124

1.3. Running additional software

Log into boltzmann to run any software other than the instrument control software. This may include, but is not limited to, tcs1_status, idl, or spex_tool.

% ssh boltzmann.ifa.hawaii.edu -l guestXX
> tcs1_status &
