Here’s a quick (albiet slightly clunky) way to use the openconnect-sso package to connect to the VPN. I’d be interested to hear if there’s a more secure, vetted, or easier process to do this. If you know about one, please write to me, and I’ll share it here. Additionally, I am sure that Yale will or may already have distributed instructions for the best way of connecting to the VPN on Linux, I’ll make sure to link to them when I find them. In the meantime, this fix should allow you to quickly connect to library resoruces or compute clusters.

Step 1: Install openconnect-sso

First, you have to install the package. If you’re on Arch Linux as I am, you can install using yay or another AUR helper.

yay -S openconnect-sso

If you aren’t on arch linux, you can also install this using the package and it’s dependencies very easily using a virtual environment:

python -m venv vpnvenv
source vpnvenv/bin/activate
pip install openconnect-sso
pip install PyQtWebEngine
pip install pyqt5

Please beware that you will have to source the virtual environment by typing souce /pathtovenv/bin/activate in the future when you want to use the openconnect command.

Step 2: Run The Command

This part’s easy! Use the –server flag to pass the VPN endpoint, access.yale.edu

openconnect-sso --server access.yale.edu
