Tuesday Tips Summer Publication Schedule



Our publication schedule over this summer will be on an as-needed basis, returning to bi-weekly in fall.

After a challenging year, we hope that everyone is able to get some rest!

(Oh . . . and please don't leave your laptop unattended on a beach!)

LS VPN Service and Duo



Over this summer, we will be transitioning to the next generation of the Letters and Science VPN service which includes Duo multi-factor authentication.

The old service will be discontinued on August 31, 2021, and VPN users have from now until then to make the switch.

For CURRENT users of the previous VPN service, switching is easy:
  1. Visit https://vpn.ls.ucdavis.edu/ (note that this is a slightly different address than that used for the previous service).
  2. Log in with your UC Davis login ID and Kerberos passphrase.
  3. You will be prompted to use Duo.
    1. Type "push" to receive a Duo push to your mobile device.
    2. Type "phone" to receive a call at your phone number registered with Duo.
    3. Open the Duo app on your mobile device, and enter in the 6 digit code under your UC Davis Duo token.
  4. Click the "Yourself (user-locked profile)" link to download your new VPN configuration.
  5. Click on the downloaded client.ovpn file to import the new configuration.
Going forward, you will be required to use Duo when connecting to the VPN.

For NEW users of the VPN service, you can find detailed directions for installing the VPN client and configuring it in the knowledge base:

(Note that you must be logged into the knowledge base to access that article.)

If you run into any issues with the new VPN service, just contact the LS IT service desk at 530-752-8800 or lshelp@ucdavis.edu.

Why are we requiring Duo for the LS VPN service?
We do realize that requiring Duo adds an extra step for using the VPN service. We consider this step as necessary: we have had several cases over the past year where the LS VPN was abused by attackers to try to compromise UC Davis services. Every one of these attacks would have been prevented by Duo. 

Do I need to use a VPN at all?
You typically only need to use a VPN if you are using resources that must be accessed from department or campus networks. Some typical reasons people use our VPN service include:
  • "Remoting" to a computer that is on one of our departmental networks, via Microsoft Remote Desktop, Apple Screen Sharing, or another remote access protocol.
  • Accessing LS File Services or other file servers remotely.
  • Connecting to a lab or department server via SSH, VNC, or NoMachine.
  • Accessing some web-based resources, such as many of the UC Davis Library databases.
