Connect from Off Campus using the Proxy Server
Coping With Problems
- I am using Firefox. I have just completed the first-time set-up instructions to set my browser to use the proxy service, but I still can't connect. I typed in my UCD login id and password and got a temporary password, but received an "incorrect browser configuration" error message.
- Close all open browser windows and then reopen Firefox (Firefox only pays attention to settings on start-up). Return to Connect From Off Campus to authenticate.
- Computers on institutional networks that connect to the Internet through a firewall and local proxy service cannot use the campus proxy service. If you are a guest on such a network, your access is blocked.
Access to UC licensed resources is provided for your personal, non-commercial use in conjunction with a course of instruction at UC or research being conducted in the course of your employment by UC. If you are a guest at another institution, your personal access may not be shared and must not be used in any way that would allow your host institution to avoid the need to license and pay for those resources independently. In accepting your computing account, you have indicated acceptance of your personal responsibility for complying.
If you and your host institution fully understand and accept the limits on your access and your host institution is willing to assist you in accessing UC resources from their network, we can be contacted for suggestions on how to facilitate your access. Remember, however, that your host institution is ultimately responsible for its own network security and has final determination over what it will and will not permit.
*Personal-computer firewall software generally doesn't interfere with your browser's ability to connect with the campus proxy service.
- Some Internet Service Providers offer an "accelerator" to improve performance. An accelerator is a network cache server provided by the Internet Service Provider. The ISP's cache server doesn't have a UCD IP address and can't access licensed resources. If your computer is set to use the accelerator, it cannot simultaneously use the campus proxy service.
- Turn off the accelerator software. The ISP accelerator will not be able to access the licensed resources. You have nothing to lose by turning it off when you need to access licensed resources, and turning it off is the only way you will gain access. Acceleration is irrelevant.
ISP Blocks Use of a Proxy Service
- ISP's network is structured in such a way as to send browser traffic through the ISP's servers and deny direct access to the campus proxy service.
- If you suspect that your ISP is blocking direct access to the campus proxy service, you should call your ISP's technical support and ask "Does your service use any egress filtering which prevents me from using a proxy on port 3128 outside of your network?" If the ISP does use egress filtering, you can ask whether they can provide a remedy. Some Internet Service Providers will accomodate your needs with a static IP address and some configuration changes. They may provide a remedy only with an increase to your monthly fees. In the event that your ISP offers to provide a remedy at increased cost, you can consider whether other available service providers will become a more cost-competitive alternative.
NOTE: This information relates to the Yahoo-branded browser specifically and only, not to the use of the Yahoo search engine or Yahoo mail.
- ISP-branded browsers like the AOL browser or the Yahoo-branded browser operate by using the ISP's cache server to make them appear to perform faster. When the browser uses the ISP's cache server, it cannot simultaneously use the UCD proxy service.
Because the ISP-branded browser can't be used with the proxy, you will have to do two things. You will have to obtain and/or configure a second browser so you can use the proxy service while connected to your ISP. After configuring a second browser, you will be able to use the proxy service, but you will have to do your internet browsing in a slightly different way.
- The proxy service is successfully set up to access library resources from off campus. However, I am on campus and wish to connect to library resources with my laptop.
- The proxy service is not needed on campus. When you bring your laptop to campus, temporarily toggle the proxy service off by going to http://www.lib.ucdavis.edu/ul/services/connect/setup/step1/, choosing the appropriate illustration, and removing the check from "automatic proxy configuration." Remember to reactivate the proxy settings when you leave campus.
Internet Explorer for the Macintosh does not support automatic proxy configuration scripting.
Safari only supports automatic proxy configuration on Macs with OS X release 10.4 "Tiger" (or later) and Safari 1.2 (or later).
For a Macintosh using OS X release 10.3 or earlier, install and configure the Firefox Browser.
The last Mozilla release for Macintosh computers running OS 9 or earlier is Mozilla 1.0.2.
Parental Control Software
- Parental control software can operate by directing URLs through a cache server. If the browser is operating with parental controls in force, it cannot simultaneously use the campus proxy service.
- You may find it simplest and most convenient to install a second browser and configure that browser for access to the proxy service. You can then adjust permissions on your machine to restrict the use of the alternate browser.
Make the following one-time (set and forget) changes before attempting to use the proxy service.
- The proxy server is not accepting my temporary password.
- Temporary passwords include upper and lowercase letters as well as numbers and can be difficult to read, especially if you are using Internet Explorer. If you copy and paste the password without leading or trailing spaces from the screen which displays it, you can avoid problems.
How to remove proxy server configuration
- I no longer need or want to use the proxy.
To undo the changes, go to Step A, choose the appropriate illustration, and reverse the changes. Remember, if you have a DSL connection and use Internet Explorer, you may need to remove the proxy autoconfiguration URL information from two places.
You do not need to reverse step 2. That change can remain.
