The Carleton Remote Labs application allows members of the Carleton community to connect to a pool of refreshing public lab machines located on campus. This can be done from any macOS and Windows computer with a reasonable internet connection, running Carleton's VPN client (GlobalProtect) or on Carleton's campus network.

About the REMOTELABS

computers are a variant on Carleton's Refreshing Lab computers. These are dual-boot macOS and Windows computers.  Any changes REMOTELABmade to the machine during the remote session will be erased at the end of the session, and the machine will restore itself to its original condition.

The REMOTELAB computers are designed to provide access to applications that students cannot install on their own computers.

Applications will perform better if they can be installed directly on a student's computer.  For a list of applications that can be installed on personal computers, see

Installing and Accessing Software on Your Personal Computer

Please Log Out of REMOTELABS

When you are finished using a REMOTELAB machine, log out of it as you would a physical lab machine BEFORE closing your Screen Sharing window.

Users who stay logged in to REMOTELAB machines for multiple days will receive a daily email from the Carleton Remote Labs Service asking them to sign out.  Click the link to see a sample message.

Hello, there - this is a friendly reminder that your username, , has been logged into Windows on userREMOTELAB-016R since 2021-01-21, more than 2 days ago.

For security reasons, no one else is allowed to connect to REMOTELAB-016R as long as you remain logged in.

Please note that simply closing the REMOTELAB window on your own computer does NOT log you out of the REMOTELAB computer; you must go to the Start menu and click Restart (Windows), or to the Apple menu and choose Log Out (macOS) on the REMOTELAB computer itself in order to log yourself out and return it to the pool of available REMOTELAB computers.

If you have already closed the window to REMOTELAB-016R, please launch the Carleton Remote Labs client, choose Windows and try to Connect again. You will be reconnected to REMOTELAB-016R so that you can log out of it as described above.

The REMOTELAB is a shared and limited resource, and we ask those who use the REMOTELAB to keep that in mind, and to log out when they are no longer actively using the computer.

Thanks for your help, and we hope you have enjoyed using the REMOTELAB.

If you have questions, please contact the ITS Helpdesk:Live chat: go.carleton.edu/helpdeskemail: [email protected]: 507-222-5999

Limited Features

Performance

Things may seem slow, depending on your internet connection, network traffic, and load on the REMOTELAB system.

If you are on a Windows machine controlling a REMOTELAB computer running macOS, this can also be slow.

Sound

Sound is not passed over a remote connection.  If you need to work with sound in an application, you will need to install it on your personal computer.

Installing and Accessing Software on Your Personal Computer

Printing and Scanning

If you have a printer or scanner connected to your personal computer, you will not be able to access them within a REMOTELAB computer

Printing and scanning from a REMOTELAB computer to a campus printer/scanner is also not supported

Saving Your Data

Any files that you want to save should be uploaded to Google Drive, Dropbox, or your cloud service of choice before you log out of the computer.  Because these are shared use machines, Google Drive and Dropbox are only accessible though a web browser.

If you save files to the Scratch Disk, remember to upload them to the cloud before you log out.  There is no guarantee that you'll be able to connect back to that same computer later to retrieve data left behind.
