What is Pulse Secure?

Pulse Secure is a free client application used to connect to the library’s Virtual Private Network (VPN). The library VPN establishes a secure connection between your computer or mobile device and the campus network. 

You will need to install and use Pulse Secure to access some UC Davis Library resources, including licensed materials, when you are off campus or on-campus but connected to a wi-fi connection other than UC Davis Eduroam (e.g., UCD Guest) or UCDH Prod on the health campus (e.g., UCDH Guest).

Once connected, you will have access to licensed library resources—those electronic materials, journal articles, library databases, streaming media services and other online tools that the library pays for on behalf of the university, but are not freely available to the public.

When do I need to connect to the Library VPN?

You need to connect to the library VPN if you are:

  • Located off-campus
  • On the Davis campus but connected to a wi-fi connection other than UC Davis Eduroam (e.g., UCD Guest)
  • At UC Davis Health but connected to a wi-fi connection other than UCDH Prod (e.g., UCDH Guest)

If you are at UC Davis Health, the best option is to connect to UCDH Prod. 

Do I need to connect to the Library VPN to access the UC Davis Library catalog?

No. Not all library resources require VPN. The UC Davis Library catalog and other free resources are open to all and do not require use of the VPN.

What kinds of licensed materials can I access when connected to the VPN?

Once connected, you will have access to licensed library resources—those electronic materials, journal articles, library databases, streaming media services and other online tools that the library pays for on behalf of the university, but are not freely available to the public.

Some vendors allow single sign-on; to access these materials, you can choose to use the Library VPN or sign into the vendor’s website using your UC Davis Kerberos (CAS) login and password instead.

How do I connect to the library VPN? What login and password do I use?

To connect to the library VPN, you must first download and install the Pulse Secure client on your computer or device. You only need to install Pulse Secure once on each device you want to use to access library resources. Once installed and configured to connect to the library VPN, you will sign into Pulse Secure using your UC Davis Kerberos (CAS) username and password. 

How do I use Duo with the library VPN?

The library VPN now requires Duo when connecting with Pulse Secure. After entering your UC Davis Kerberos (CAS) username and password, a secondary prompt will appear asking for your Duo code or command. Please use one of the following options:

  • Push – Enter the word “push” and click Connect. You will receive a push notification to your Duo app that you must then approve. *This is the recommended method
  • Phone – Enter the word “phone” and click Connect. Duo will call your registered phone number for authorization.

Note: For either the “push” or “phone” commands, if you wish to have Pulse Secure use that method every time you connect, click the “save settings” box before clicking connect.

  • Code – Enter your passcode from your Duo hard token or the Duo app and click Connect.

IMPORTANT: Do NOT click “save settings” when entering a passcode or your next time using Pulse Secure will fail because the saved passcode will no longer be valid. You will have to right click (control click on Mac) on the connection for the library VPN in Pulse Secure and choose “Forget Saved Settings” from the menu that appears. You will then have to re-enter both your login credentials and the Duo code/command when you connect.

How do I connect to the library VPN from UC Davis Health?

Due to differences in computer networks at UCDH, the library offers these options for accessing library-licensed resources from the UC Davis Medical Center campus or other UCDH clinical sites:

If you are onsite at UC Davis Medical Center:

  • Connect to UCDH Prod WiFi OR UCDH VPN (Cisco AnyConnect) using your UCDH Citrix credentials. If this does not work, you can use the UCDH Citrix Application or a health system terminal by logging in with your UCDH Citrix credentials (note: using IE11 may provide better website functionality).

If you are at a remote clinic or offsite, either:

  • Connect to the library VPN using Pulse Secure on your computer or mobile device using your UC Davis CAS/Kerberos credentials, 

OR

Once you are connected to the UC Davis network using one of the above options, you should be able to navigate to library-licensed resources via the library website or directly. If you have trouble, submit a Technical Support Request.

Will Pulse Secure work with my computer’s operating system or my mobile device?

Pulse Secure should work for the majority of faculty, staff, and students. Please refer to the installation instructions for your operating system and/or mobile device. Keep in mind that once you install Pulse Secure, you will need to update it periodically, as you would with any software. 

Can I connect using Linux?

Yes, there is a Pulse Secure client for Linux users. Please note, Linux is not an officially supported operating system. Users may try this client at their own risk.

Two package types are available for the two most used methods, rpm and deb:

An icon for Pulse Secure will be added to your applications menu. Launch the application and add a connection. Use “vpn.library.ucdavis.edu” 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/PulseClient.sh -h vpn.library.ucdavis.edu -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.

How do I get to library materials once I am connected to the Library VPN?

Once Pulse Secure is connected to the library VPN, you may use the browser of your choice to browse directly to your desired electronic resource, or you may browse databases.

Do I need to connect to the Library VPN every time?

Yes. You must sign into the library VPN using your UC Davis Kerberos (CAS) credentials every time you want to access licensed library resources from off campus.

Once I’ve installed Pulse Secure, where can I find it on my computer the next time I want to connect to the Library VPN?   

On a Mac, you can find the Pulse Secure icon at the top right of your display. On Windows, you can find the client by searching for Pulse Secure in the Start menu. For easy access on Windows, we recommend pinning the Pulse Secure client to your taskbar.

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 on campus or use the library VPN to access many journal articles. Additionally, to access the full-text of articles you must customize the “Library Links” settings within Google Scholar. See Google Scholar tutorial video.

Can I use multiple multiple browser windows once I login to the Library VPN?

Yes, you may open multiple windows or multiple tabs. Either method works using Pulse Secure.

Can I use my browser’s bookmarks in the Library VPN?

Yes, once Pulse Secure is connected to the library VPN, you may use your bookmarks normally.

Known errors with Mac OS

Mac OS X 10.15 (Catalina): “PulseSecure.pkg can’t be opened.”

The latest version of Pulse Secure will work with Catalina. You may encounter a warning when trying to install that “PulseSecure.pkg can’t be opened because Apple cannot check if for malicious software” with no option to continue the installation. This is from double-clicking on the pkg file. If you right-click or control-click on the file and choose open, the same warning dialog will appear, but it will then present an open button in that dialog box to let you proceed with installation. Click open to continue the installation.

Mac OS X 10.14 (Mojave).

The latest version of Pulse Secure will work with Mojave. You may encounter a periodic warning that Pulse Secure “is not optimized for your Mac and needs to be updated.” This is because the current version is still 32-bit, but it will run on your 64-bit Mac. Please click “ok” to dismiss the warning notice. More information about 32-bit apps on the latest macOS can be found here.

Mac OS X 10.13+ “Failed to setup virtual adapter. (Error:1205).”

Go to your System Preferences and select Security & Privacy. On the “General” tab, look towards the bottom of the window for a message indicating that Pulse Secure is being blocked. Click the “allow” button. You should now be able to log in with Pulse Secure.

Mac OS X 10.12 and lower.

Pulse Secure requires Mac OS X 10.13 or higher. We would highly recommend upgrading your Mac to at least 10.13 in order to utilize Pulse Secure. Please contact Apple support if you are unsure whether your Mac can be upgraded.

Known errors with Microsoft Windows

Windows 10 “Failed to setup virtual adapter. (Error:1205).”

Go to your Control Panel and open “Programs and Features”. Uninstall any listings with either “Juniper Networks” or “Pulse Secure” in the name. Reboot your computer and then download and install a new copy of the Pulse Secure client from our site.

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

Installation fails with message below or similar:

An error occurred during the installation of assembly
‘Microsoft.VC80.CRT,type=”win32″,version=”8.0.50727.762″,publicKeyToken=”1fc8b3b9a1e18e3b”,processorArchitecture=”amd64″‘.

    • Windows Management Instrumentation
  4. Try Pulse Secure installation again.

I’ve installed Pulse Secure but I can’t connect. The application 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 vpn.library.ucdavis.edu.

My campus ID and passphrase aren’t working with Pulse Secure, but I can log into other campus services.

The library VPN uses your UC Davis Kerberos (CAS) username and password 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 UC Davis Knowledge Base for instructions on how to change your passphrase. Once reset, you should then be able to log into the library VPN.

I logged in twice and got a warning page.

The Library VPN only allows one session at a time per user. You will get this error if you are using Pulse Secure on a mobile device and then try to connect with your laptop or desktop computer. You must disconnect the previous session first before starting the next session on your other device.

Closing Pulse Secure without disconnecting first can also cause this error. Please ensure that you are disconnecting Pulse Secure when you are done searching for articles/journals. To ensure Pulse Secure has no lingering sessions or connections, please try completely exiting Pulse Secure and then relaunching it from your Start menu (Windows) or Applications folder (Mac), or by rebooting your computer.

Please note, any sessions will timeout after 15 minutes of idle use, or at a maximum session of four hours, so you should be able to log in at that time if this issue occurs.

I’m at UC Davis Health and using Citrix. How do I connect?

Please refer to the options for connecting to the library VPN from UC Davis Health in the “Getting Started” section above.

When trying to connect, Pulse Secure gets stuck at “Securing connection” even if I close it and try again.

Please restart your computer and try to connect Pulse Secure to the library VPN again.

I’m connected, but having issues accessing a licensed resource.

Try clearing your cache/cookies before starting the VPN client.

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

This is a known issue for users who are running antivirus or Internet security software. You must temporarily disable the software to successfully install the Pulse Secure client. Simply “pausing protection” or stopping the software does not work. Please search Google or your preferred search engine for “how to disable antivirus or Internet security software X” where X is the type and version you are running, such as “Kaspersky Internet Security 2020.” Please remember to re-enable your antivirus or Internet security software after installing Pulse Secure.

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

If you are running antivirus or Internet security software on your device, it may  conflict with Pulse Secure. Temporarily disabling the software should allow Pulse Secure to install/connect/work without issue. 

My other applications (e.g., FTP, BitTorrent, Streaming, SSH, etc.) won’t work while connected to the Library VPN.

The library VPN is intended for access to electronic library resources only. Per UC Davis Cyber Safety policies, service ports on the library VPN have been restricted to web browsing and email only (access to campus services and networks remains unrestricted). Other Internet applications to external services, such as FTP or SSH, will not function until the library VPN is disconnected.

We recommend connecting to the library VPN when needing to access electronic library resources and then disconnect once your search is completed to limit disruption of your other Internet applications.

Accessing licensed resources using an IPv6 campus network

Some campus units have switched to using IPv6 for their network access. Please be aware that licensed resource vendors do not 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.

Vendors using IPv6 networks

Some vendors, such as IEEE, are using IPv6 for their networks. If you are also using IPv6, this can create a problem when attempting to access resources on that vendor’s site while using the library VPN. This is due to IPv6 taking precedence over IPv4, which is what the library VPN uses. So while the library VPN may be connected, your browser is opting to send traffic to the particular vendor site via IPv6 instead of IPv4, causing the vendor to think you are not on a valid UC Davis IP address and requesting that you sign in or pay for access. 

To correct this, please temporarily disable your IPv6 network while using the library VPN and searching such vendor sites so that the traffic gets routed via the library VPN and is recognized by the vendor site, allowing access. You may re-enable your IPv6 network once you are finished searching and have disconnected the library VPN.
