| Starting and stopping a SAMP hub server |
| *************************************** |
|
|
| There are several ways you can start up a SAMP hub: |
|
|
| Using an existing hub |
| ===================== |
|
|
| You can start up another application that includes a hub, such as |
| `TOPCAT <http://www.star.bris.ac.uk/~mbt/topcat/>`_, |
| `SAO Ds9 <http://ds9.si.edu/>`_, or |
| `Aladin Desktop <http://aladin.u-strasbg.fr>`_. |
|
|
| Using the command-line hub utility |
| ================================== |
|
|
| You can make use of the ``samp_hub`` command-line utility, which is included in |
| Astropy:: |
|
|
| $ samp_hub |
|
|
| To get more help on available options for ``samp_hub``:: |
|
|
| $ samp_hub -h |
|
|
| To stop the server, you can simply press control-C. |
|
|
| Starting a hub programmatically (advanced) |
| ========================================== |
|
|
| You can start up a hub by creating a |SAMPHubServer| instance and starting it, |
| either from the interactive Python prompt, or from a Python script:: |
|
|
| >>> from astropy.samp import SAMPHubServer |
| >>> hub = SAMPHubServer() |
| >>> hub.start() |
|
|
| You can then stop the hub by calling:: |
|
|
| >>> hub.stop() |
|
|
| However, this method is generally not recommended for average users because it |
| does not work correctly when web SAMP clients try and connect. Instead, this |
| should be reserved for developers who want to embed a SAMP hub in a GUI for |
| example. For more information, see :doc:`advanced_embed_samp_hub`. |
