Remote User Access
Using the IP Extension Service

Quick Links Getting Started with the IP Address Extension Service Adding the Service is a two-step process: Registering your computer Configuring your computer The IP Extension Service does not need to be used to access certain resources remotes. Instead, WebISO is used for accessing, which happens automatically when a user accesses one of these sources: course reserve readings listed in Cameo, audio reserves listed in Cameo, SciFinder Scholar, and CTMS/MatLab. Why Use the IP Address Extension Service? Most of the databases and other digital resources available at the University Libraries are licensed for users who are physically located at Carnegie Mellon computers or who dial-up locally via Andrew. However, many Carnegie Mellon affiliates are remote users, and many use their own Internet Service Provider, leaving them unrecognized by the licensed resources. No matter where you are, or what ISP you are using, you can "authenticate" (login with Andrew userID and password) using WebISO or connect through the IP Address Extension Service, and have complete no-cost access to digital resources, if you are a current student, faculty or staff member of Carnegie Mellon. Getting Started IP Address Extension Service explains what the Service does, and what system requirements there are. Getting Started with the IP Address Extension Service walks through the steps needed for set-up, determined by the type of computer and operating system version you are using. The two-step process involves: Registering your computer Configuring your computer Be aware that Computing Services is NOT implementing encryption with the Carnegie Mellon IP Address Extension Service, as is common to most VPN services. Therefore, network communications with remote sites should NOT be considered secure. Also, using the IP Address Extension Service appears almost seamless, but you should remember to disconnect. Once you are done using resources that require authentication (library databases, for example), you should disconnect from the Service, or else all your web traffic will run through the VPN, potentially slowing down your machine's response time. May I Still Use the Proxy Server? Yes, the old proxy server links will remain active for a short time, but not indefinitely. Here are the links, for your convenience: Library home page via the proxy server Carnegie Mellon Proxy Server FAQ about the Proxy Server (Your web browser must have Java, JavaScript, and Cookies enabled to use the proxy server.)

	What's New

IMPORTANT: The proxy server will remain active for a short time, but is being phased out. It is no longer supported by Campus Computing or the University Libraries. When you experience problems using the proxy server, you are advised to implement the VPN on your computer.

Shibboleth Pilot Project
The University Libraries are working with Computing Services, Internet2, database vendors, and other institutions to implement a pilot project using new client/server technology. Shibboleth is a potential alternative to IP-address restriction that will improve access to e-resources in the future.

The software will enable authenticated users to access "shibbolized" library resources (particularly, databases purchased and licensed for campus users) with one log-in. Part of the beta program will be to determine the viability of Shibboleth as a tool for libraries and also whether Internet2 and vendors can support the software.
