Connect from Off Campus using VPN
Questions & Known Issues

Getting started

What login and password do I use?

Your UC Davis login and password. (You may request an account if you are a UC Davis student, faculty, or staff member.)

I logged in twice and got a warning page.

Only log in once using your UC Davis Kerberos username and password.

How do I get to library resources once I have logged in using VPN?

Once the VPN client is connected you may use the browser of your choice to browse directly to your desired electronic resource, or you may search the library listings.

Using the VPN

If I find links to articles using Google Scholar or while conducting a Web search, will I need to authenticate to get to the actual articles?

You must be recognized as current UC Davis faculty, staff, or student to access the full-text of articles. Logging into the VPN client before beginning to search for resources may be the most efficient method.

I like to use multiple windows when I am searching and viewing resources. Can I use multiple tabs in Firefox or multiple browser windows once I login to the VPN service?

Yes, you may open multiple windows or multiple tabs. Either method works using the VPN client.

What if I'm browsing normally without the VPN, and come across a site I need to use the VPN for? Can I use my bookmarks in the VPN?

Yes, once the VPN client is connected, you may use your bookmarks normally.

What is Pulse Secure?

Pulse Secure is an app for Windows, Mac OS X, iPhones and Android devices that provides a VPN client for these operating systems and mobile devices. Use Pulse Secure to log into the UC Davis network using either wifi or your telecommunication provider's services. You will have network access to resources such as UpToDate, online journals and books, and other licensed resources.

Pulse Secure is a free app. Of course you may have network charges from your telecommunication provider, depending on your service plan.

Is there a client for Linux users?

Yes, there is a Pulse client for Linux users. It comes in two package types for the two most used methods, rpm and deb. The packages can be obtained from the following links:

An icon for Pulse Secure will be added to your applications menu. Launch the application and add a connection. Use "" as the URL setting. Once a connection is created, click connect and log in with your campus ID and passphrase.

For command line use, use the following to launch the VPN client:

/usr/local/pulse/ -h -u <your kerberos id> -r Library

You will be prompted for your kerberos passphrase.

More information about the client can be found at Pulse Secure's Knowledge Base.

Linux is not an officially supported operating system. Users may try this client at their own risk.

Known Issues

Are there Web sites that don't work with VPN? How do I access these sites?

We are not currently aware of any sites that do not work with the VPN client.

When trying to connect with the Pulse Secure VPN client, it gets stuck at "Securing connection" even if I close the client and try again.

Please restart your computer and try the Pulse Secure client again.

Mac OS X 10.7 and lower.

The Pulse Secure client requires Mac OS X 10.8 or higher. We would highly recommend upgrading your Mac to at least 10.8 in order to utilize Pulse Secure. Please contact Apple support if you are unsure whether your Mac can be upgraded.

If your Mac canont be upgraded to 10.8 or higher, you may still use the Library VPN using the previous, Network Connect client. The Library does not officially support this method as the vendor, Pulse Secure, may cease to support this version of the VPN client at a future date. However, until such time, users may use Network Connect.

The current version of Network Connect can be downloaded here. Please use the following URL in the "Sign in" field of the application:

My campus ID and passphrase are not working with the new Pulse Secure client, but I can log into other campus services.

The Library VPN uses your campus ID and passphrase for authentication. If they are not working, then the campus service that the Library VPN uses for authentication is not synced properly with your campus computing account and you will need to reset your passphrase.

Please visit for instructions on how to change your passphrase.

Once reset, you should then be able to log into the Library VPN.

The Pulse Secure client connects but either does not stay connected or my browser does not work while it is connected.

Other patrons with this issue have found that they are running Kapersky Internet Security and it was conflicting with the Pulse Secure client. Temporarily disabling the software allowed the client to install/connect/work without issue.

Pulse Secure is installed but is not configured or is asking for a Server/URL.

The Server or URL setting to use with Pulse Secure for the Library VPN is

IPv6 campus networks.

Some campus units have switched to using IPv6 for their network access. Please be aware that licensed resource vendors do no currently recognize UC Davis IPv6 networks for allowing access to electronic resources. If you are on an IPv6 network and cannot access an electronic resource, please try using the Library VPN until such time that the vendors can be notified and updated to allow UC Davis IPv6 networks. You can also choose to disable your IPv6 interface when needing to access licensed resources so that you are then using an IPv4 campus address.

Pulse Secure install stops, backs out, and then reports the installation failed.

This is a known issue for users that are running Kaspersky Internet Security. You must temporarily disable Kaspersky in order to successfully install Pulse Secure. Simply "pausing protection" or stopping the software does not work. Please search Google or your preferred search engine for "how to disable Kaspersky Internet Security X" where X is the version you are runnig, such as Kaspersky Internet Security 2016. Once disabled you should be able to install the Pulse Secure client successfully.

Please remember to re-enable Kaspersky after installing Pulse Secure.

Pulse Secure installation fails with Microsoft.VC80.CRT error.

Installation fails with a message similar to the following:

An error occurred during the installation of assembly
Please refer to Help and Support for more information.

Please try the following:

  1. Open command prompt window as admin and run the following command:
    fsutil resource setautoreset true C:\
  2. Reboot system
  3. Open Services and ensure the following services are in a running state:
    Windows Installer
    Windows Management Instrumentation

Try Pulse Secure install again
