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, SAO DS9, or Aladin Desktop.

Starting a Hub Programmatically

You can start up a hub by creating a pyvo.samp.SAMPHubServer instance and starting it, either from the interactive Python prompt, or from a Python script:

>>> from pyvo.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 to connect. Instead, this should be reserved for developers who want to embed a SAMP hub in a GUI, for example. For more information, see Embedding a SAMP Hub in a GUI.
