ITaP Research Computing provides ThinLinc as an alternative to running an X11 server directly on your computer. It allows you to run graphical applications or graphical interactive jobs directly on Halstead through a persistent remote graphical desktop session.
ThinLinc is a service that allows you to connect to a persistent remote graphical desktop session. This service works very well over a high latency, low bandwidth, or off-campus connection compared to running an X11 server locally. It is also very helpful for Windows users who do not have an easy to use local X11 server, as little to no set up is required on your computer.
There are two ways in which to use ThinLinc: preferably through the native client or through a web browser.
As of 3 December, 2018, if you use Thinlinc from off-campus, you will need to connect to the Purdue VPN first.
Installing the ThinLinc native client
The native ThinLinc client will offer the best experience especially over off-campus connections and is the recommended method for using ThinLinc. It is compatible with Windows, Mac OS X, and Linux.
- Download the ThinLinc client from the ThinLinc website.
- Start the ThinLinc client on your computer.
- In the client's login window, use desktop.halstead.rcac.purdue.edu as the Server. Use your Purdue Career Account username and password.
- Click the Connect button.
- Continue to following section on connecting to Halstead from ThinLinc.
Using ThinLinc through your web browser
The ThinLinc service can be accessed from your web browser as a convenience to installing the native client. This option works with no set up and is a good option for those on computers where you do not have privileges to install software. All that is required is an up-to-date web browser. Older versions of Internet Explorer may not work.
- Open a web browser and navigate to desktop.halstead.rcac.purdue.edu.
- Log in with your Purdue Career Account username and password.
- You may safely proceed past any warning messages from your browser.
