Why does the proxy server reject my username and password?

If you are getting prompted over and over again to enter your username and password, make sure you're using the right username and password!

If you are logging in with a CalNet ID:

  • Make sure that the "Caps Lock" key on your keyboard is not in effect.
  • Test whether your CalNet ID is still valid and log in.
  • Note: To protect your privacy on a shared computer, quit the web browser when your session is finished.

If you are logging in with a library PIN:

  • Make sure that you are using the number printed on your current UCB Library Card or Cal 1 Card.
  • If needed, reset your PIN by clicking on the "Forgot your PIN or don't have a PIN?" link on the Login to My OskiCat screen.
  • Make sure that the email address is the one associated with your Library account. If you're not sure which email address you use for this purpose, log into My OskiCat and use the address displayed there.

If your username and password were accepted but you see a message such as "Proxy authorization failed", your Library privileges may have expired or your affiliation with UC Berkeley may not warrant access to the proxy server.

Only UC Berkeley students, faculty and staff, and some other individuals affiliated with the University, are eligible to use the proxy server. If you have questions concerning your eligibility for Library services, please contact the Privileges Desk in Doe Library (510-642-3403).

I use VPN but can't access licensed resources, or get incorrect results.

Products such as Google Web Accelerator and the Firefox plugin DownThemAll can make web pages load more quickly. However, they can also cause problems when using electronic information resources that the library subscribes to, such as journal article databases.

When you try to use these resources through a web accelerator, it comes between your computer and the website you are using, masking your UC Berkeley IP address and caching pages from the site for later use. Consequently, you may not get correct results or may not be able to log in at all. This can happen whether you are on or off campus, and even when you are using our proxy service or VPN.

For this reason, we recommend turning off your web accelerator before using our website, or setting it to ignore specific databases, etc. that you plan to use. Please see the Wikipedia article about Google Web Accelerator.

Can I continue to print while connected to the VPN?

If the printer is physically attached to your computer, it should continue to work while your VPN connection is active.

If the printer is connected via a wireless or other Local Area Network, you will have to change a setting in the VPN client to "enable local LAN access".

You can also defer printing by choosing the "print to file" option to save the print stream on your computer, then print the resulting file after you disconnect from the VPN.

Can I set up the VPN client to automatically connect at startup?

No, the Cisco VPN client cannot automate the login process.

How do I start up VPN?

Please see the VPN nstructions for Windows, Macintosh, and Linux computers.

Who installs the VPN software?

You, the user. At home, on your personal computer, you are responsible for selecting an Internet Service Provider (ISP), coordinating installation, and installing any required software. This includes the VPN client. You should not need to use the VPN from an on-campus computer.

How do I get the VPN software?

The instructions for MacintoshWindows, and Linux computers will guide you through the process of downloading and installing the VPN client software.

Does VPN offer virus protection?

No. VPN provides security by encrypting and decrypting data that passes through a VPN connection; it does not offer protection from viruses or other malware.

Can I use VPN through a firewall?

If you are having trouble connecting and have a firewall, you can test it by disabling the firewall and trying again.

If your computer is behind a firewall that restricts access by IP address, its settings may need to be modified to allow access via the VPN. For more information see this UC Berkeley IST Knowledge Base article.
