Access from Off Campus (VPN)

Yale's clusters can only be accessed on the Yale network. Therefore, in order to access a cluster from off campus, you will need to first connect to Yale's VPN. More information about Yale's VPN can be found on the ITS website.

VPN Software

Windows and macOS

We recommend the Cisco AnyConnect VPN Client, which can be downloaded from the ITS Software Library.


On Linux, you can use openconnect to connect to one of Yale's VPNs. If you are using the standard Gnome-based distros, use the commands below to install.


sudo apt install network-manager-openconnect-gnome


sudo yum install NetworkManager-openconnect

Multi-factor Authentication (MFA)

Authentication for the VPN requires multi-factor authentication via Duo in addition to your normal Yale credentials (email address and netid password). After you select "Connect" in the above dialog box, it will launch a web page with a prompt to login with your email address, netid password and MFA method.

You can click "Other options" to choose your authentication method.

  • If you choose "Duo Push", simply tap "Approve" on your mobile device.
  • If you choose "Duo Mobile passcode", enter the passcode from the Duo Mobile app.
  • If you choose "Phone call", follow the prompts when you are called.

Once you successfully authenticate with MFA, you will be connected to the VPN and should be able to log in the clusters via SSH and Open OnDemand as usual.

More information about MFA at Yale can be found on the ITS website.
