Using Skype at GM/CA @ APS

Users doing experiments at GM/CA beamlines can use Skype for convenient communication with their partners and users working remotely.

Skype options when you are at GM/CA facilities

You may use Skype either on your personal laptop or launch the pre-configured Skype account on Workstation-3.

  1. If you are using your personal laptop:

    • First, connect wirelessly to the "Argonne-guest" network.
    • After establishing the TCP/IP connection, open a web browser on the laptop. If this is the first time you are connecting or if the laptop was not connected to "Argonne-guest" for more then a year, the web browser should display a registration form that you need to fill out following the form instructions. Otherwise, verify that you are connected to the internet and can browse outside web pages. If the browser does not show the form and you do not have a connection, try another browser if you have it installed and try entering "" as the URL.
    • Once the connection is verified, you can start using Skype. Normally, no special Skype configuration should be required.
  2. If you wish to use Skype installed on Workstation-2:

    • Turn on the speakers bar and the microphone attached to WS2.
    • Skype on WS2 is pre-configured to auto-login as gmca23i, gmca23o, or gmca23b (depending on the beamline) for all users accounts. If you find that Skype is not logged in, ask your host to login for you. Do not logout from Skype (!) because to login back you would need the password that only your host knows. Since Skype accounts are shared between all users of particular beamline, hosts cannot disclose Skype passwords to users due to security reasons.
    • Be aware that Skype has a non-standard way of closing. Just clicking on the right top corner of the main Skype window does not actually close Skype. Instead, find the Skype icon in the system tray (the right corner of the bottom panel on the computer screen), right-click on it and choose "Quit". Do not logout from Skype before closing it!
    • You can make Skype video calls on WS2 as there is a webcam attached to the top of the WS2 display.

Skype calls to GM/CA @ APS

When skyping to GM/CA beamlines, please call names gmca23i, gmca23o, or gmca23b, -- depending on the beamline. It will be a good idea to notify your host in advance that you are planning to communicate via Skype because by default the application is not started on WS3.


Frequently Asked Questions:

Q: I start Skype, but it cannot connect to the Skype server.
