Off-campus Access to Library e-Resources FAQ

  1. How come I can't login to Library VPN?

    Library VPN service is available to PolyU staff. Please refer to the Network Access - Off campus page for more details. Alternatively, valid Library users may remotely access Library e-resources via the EZproxy Server instead of going through the VPN (Virtual Private Network) services. 

  2. Any setup requirement for my PC at home?

    You will need an Internet connection and browser to access EZproxy. No client software installation is required. EZproxy should work on any operating system with any browser such as IE or Firefox. EZproxy doesn’t require any browser configuration.

  3. I can’t log in with my username and password. What do I do?

    Please check your NetID & NetPassword or call ITS helpdesk at (852)2766-5900 to verify your account status. 

  4. What can I do if I got a Cookie error message?

    After the authentication, a “cookie” is sent to your browser as an ongoing indication of your authorization to access this database. If you got a cookie error message, your browser may be currently set to disallow cookies. Just change your browser back to the default setting to ACCEPT COOKIES.

  5. What can I do if I got a Javascript error message?

    Javascript needs to be enabled for the proxy service to work. Just change your browser back to the default setting to ENABLE JAVASCRIPT.

  6. What can I do if I got a Hostname error message?

    You will get a Hostname error message when you attempt to access a database that has not yet been set up for use by EZproxy. This happens when database vendors change domain names or move the content to a new host without informing the libraries. To correct this error, please send the error message to lbsys@polyu.edu.hk or call (852)2766-6896 to update the new host to EZproxy’s configuration file.

    Example:

    To allow http://www.testing.com to be used in a starting point URL, your EZproxy administrator must first authorize the hostname of this URL in the config.txt file. Within this database's section of config.txt, the following line must be added: Host www.testing.com The EZproxy server must then be restarted to make the change take effect.

     

  7. I got a security warning message “The name on the security certificate is invalid or does not match the name of the site” after logged in with my username and password. What should I do?

    Click OK to continue. EZproxy server requires a certificate to provide SSL (Secure Sockets Layer) encryption of user login information. In some situations, the browser may get confused because the web address doesn’t exactly match to the address in the certificate.

  8. I can’t access the database at my office. How come?

    Some company or institution’s Internet connection may automatically configure browsers to use their own proxy server. This automatic setting might affect the use of EZproxy. Company or instituation’s firewall or Internet security setting might also affect the use of EZproxy. You will need to talk to the network administrator in your organization.

  9. Why some of my bookmarks or saved links to library databases no longer work from off campus?

    Because EZproxy is a rewriting passthrough proxy server, all URLs for licensed resources are prefaced by http://ezproxy.lb.polyu.edu.hk/login?url= to force all requests to pass through the EZproxy server. You can update your bookmarks or saved links by editing them to include the EZproxy prefix. 

  10. How to create a link to library subscribed database?

    When linking to the databases that the Library subscribed to, you need to add the EZproxy prefix to the beginning of the URL. The EZproxy prefix is: http://ezproxy.lb.polyu.edu.hk/login?url=
     

    • Locate the direct link to the library resource (database, journal article, ebook, media services materials) that you want to save.
    • Add the direct link to your selected library resource to the end of the EZproxy prefix.
    • The final link you created will provide access to the resource both inside and outside of PolyU campus.

    Example : Create an EZproxy link for database title ABI/INFORM

    • Locate the direct link for database title ABI/INFORM : http://www.umi.com/pqdauto?ts=0
    • EZproxy prefix : http://ezproxy.lb.polyu.edu.hk/login?url=
    • Append the direct link to the end of the EZproxy prefix : http://ezproxy.lb.polyu.edu.hk/login?url=http://www.umi.com/pqdauto?ts=0
