The University Libraries subscribes to a number of resources that by contract (license) are restricted to use by faculty, staff and students currently registered or employed at UNL. As a consequence, if you are working off-campus, you will have to verify your affiliation with UNL and access these resources by proxy.
Beginning August 2, 2004 a new proxy server was implemented that no longer requires authorized users to configure their Internet
browser.
If you previously configured your browser you will need to remove this information. Directions on how to remove the proxy server configuration may be found below for most browsers.
Once you have removed proxy server configuration, when you go to a restricted database you will be prompted for your login and password. The login is your last name and the password is the NU ID Number found on your NCard.

A Note About "cookies"
Many of the indexes pass "cookies" to your browser. Cookies are strings of
text information that are used by some web sites to keep track of your searches,
format results, and for other purposes. If you set your browser to refuse all
cookies or use software that "strips" or otherwise restricts cookies, you will not be able to use the new proxy. Enabling cookies while using the indexes
is required.
The default setting for most browsers is to accept all cookies. If you are
not sure what your settings are or how to change your settings, consult your
browser's help file. Internet Exporer 6 users - check the settings under
Internet Options and the Privacy tab, this needs to be set to low for many of
the Libraries' databases.
A Note About Java & Java Script
Many of the indexes use Java and Java Script in their applications. To use
JAVA you must have a java capable operating system like Windows95 or Windows98.
Windows 3.X versions do not support Java. Java Script runs on all Windows
platforms including Windows 3.x if you have enabled Java Script through
your browser.
Tips on Configuring a Firewall with the Libraries
Databases
Individuals who use a firewall to protect their home
computer may want to configure their firewall so they can access specific
databases in the Libraries. Since firewalls differ in this configuration these
directions are general. The UNL Libraries uses a variety of computers for our
databases. Some are on campus and others are maintained by vendors all around
the country. This means that the IP numbers and port assignments vary with the
database. The following information should help you get started. For more
information mailto:iit@unlnotes.unl.edu please
include which database you want to connect to.
The Libraries use several computers for the ICA Client databases. Here are
databases that use the ICA Client:
- Routledge Encyclopedia of Philosophy
- Scifinder
- World Development Indicators
- American Film Institute Catalog
- AMS Comference and Symposium Preprints
- English Short Title Catalogue
These are the IP numbers that are
used for the databases:
- 129.93.17.161
- 129.93.16.66
- 129.93.16.145/
- The ICA WINFRAME uses dynamic port allocation which means that there
isn't any single port number assigned. The initial synchronization between the
WinFrame client and the WINFRAME server occurs over port 1494, but the actual
WINFRAME session occurs over a dynamically allocated port. For this reason, it
is might be necessary to allow connections over a range of TCP/IP ports
through the given firewall. The client contacts the server over tcp port 1494.
The server sends a message back to the client over tcp port 1494 saying
"connect using port X" where X is any port number above 1023. This is called
using TCP High Ports. All of the ports under 1023 are reserved for system use
and "Well Known" protocols such as FTP, HTTP etc. The WinFrame server will
dynamically allocate a specific port above 1023 for each TCP/IP session. This
is how we can support multiple sessions at one time. Each one has it's own
port. How do you configure this - either allow connections through all ports
or allow communications over TCP High Ports. Some firewalls allow you to do
this by setting an option in the rules.
