Penfield Library's website has several features that improve service and access. Some of these features require the user to verify that they are part of the SUNY Oswego community. Other features may conflict with the set up of certain ISP (Internet Service Providers) and network firewalls. This page answers basic questions relating to these aspects of our site.

Ports and Firewalls:

Some web services use a specific port to connect to a computer network. Different ports allow different types of data transfer to take place. These include Penfield's:

Library Catalog

Our library catalog uses ports 4470 and 4479 to transfer data from our server to your computer. If you have difficulty accessing our library catalog, you may need to have your ISP or network administrator open ports 4470 and 4479. This is not done by the Library, nor is it a change you can make in your computer.

Databases & Indexes

Our databases and indexes use ports 2048 and 443 to transfer data from our server to your computer. If you have difficulty accessing our library databases, you may need to have your ISP provider or network administrator open ports 2048 and 443. This is not done by the Library, nor is it a change you can make in your computer.

Computer Account Required to Access Restricted Services

To access services that have licensing agreements restricting their use to SUNY Oswego users, you must verify that you are a SUNY Oswego student, faculty or staff member.

If you are off campus, you will be prompted for a Laker NetID and password the first time you access (click on) a restricted service. These are the same as you use for Blackboard or to log into a campus computer.

New Students

New students are assigned a computer account upon registering for classes and paying their bill. The account must be activated before you can use it. To activate your account:

Note: Online activations will become active within 24 hours. You will be required to submit your date of birth and your University ID number to activate your account online. This same account allows you access to the computers in the library and in CTS labs throughout campus.
