Library VPN Questions & Known Issues

What login and password do I use?

Your UC Davis Computing Account 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 Computing Account username and password.

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

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

Alternative methods of accessing library resources (UCDH)

UC Davis Health offers alternative methods for accessing library resources.

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 Pulse Secure Client connected to the Library VPN. Additionally, to access the full-text of articles you must customize the “Library Links” settings within Google Scholar. See Google Scholar tutorial video.

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 Library VPN service?

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

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

Yes, once the Pulse Secure client is connected to the Library VPN, 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.

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.

My other Internet applications (FTP, BitTorrent, Streaming, SSH, etc) do not work while connected to the Library VPN.

The Library VPN is intended for access to electronic resources only. Per UC Davis Cyber Safety policies, service ports on the Library VPN have been restricted to web browsing and email only. Other Internet applications, such as FTP or SSH, to external services will not function until the Library VPN is disconnected. It is our recommendation to connect to the Library VPN when needing to access electronic resources and then disconnected once your search is completed in order to limit disruption of your other Internet applications.

This does not affect campus services or use of Office 365. Access to campus networks remains unrestricted via the Library VPN.

If you encounter any issues accessing a licensed electronic resource, please submit a Technical Support Request to the Library indicating the resource you are having trouble with along with any details you can provide on the issue and Library ITIS staff will address it as quickly as possible.

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.

What happened to the Windows 10 Native App?

The Windows 10 Native App via the Microsoft Store is no longer supported by Pulse Secure and is no longer recommended by Library ITIS for use with the Library VPN. We can no longer ensure reliable connectivity and access via this method and all patrons should, instead, use the Pulse Secure Desktop Client.

Mac OS X 10.15 (Catalina).

The latest Pulse Secure client 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 Pulse Secure client 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 client 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-bits 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.

The Pulse Secure client 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.

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 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.

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 client 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 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.

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 running, 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 client installation fails with Microsoft.VC80.CRT error.
