Overview

A virtual private network (VPN) is a mechanism for creating a secure connection between a computer and a computing network using an insecure communication medium like the Internet. You can access the resources available within the network from your computer using a VPN.

You will find the following VPN services useful for accessing some of the resources offered by the Research and Discovery Technologies:

  • UA SSL VPN (vpn.arizona.edu): If you are not connected to the UA campus network, you will need to connect to this VPN to access R-DAS.  Connections are limited to 24 consecutive hours.
  • UA HPC VPN (vpn.hpc.arizona.edu): You will need to connect to this VPN to use graphical applications, that need X11 forwarding, or to use VSCode remote connections, with the HPC clusters.  Connections are limited to 24 consecutive hours.
