Wired Residential Network
How can I get an Internet connection from Columbia University Medical Center student housing?
Please follow the instructions found on our Student Residential Network page.
What is Bradford Campus Manager?
Bradford Campus Manager is a tool that is used to provide fast registration for wired connectivity on campus. It is currently active at Bard Hall housing, Georgian 5th floor, 154 Haven and Towers I, II and III for student computers that plug into the wired network at any of these locations. All three Towers also use Bradford for wireless access, though computers must still first be properly configured to connect to wireless.
Registration involves submitting an online form and running a small, non-permanent program to quickly scan the computer for basic security requirements: current operating system updates and current, working antivirus and antispyware programs. Please see the Bradford Use and Bradford Steps page as well as the FAQs below for more information.
Who should register via Bradford Campus Manager?
Any student may register via Bradford.
Faculty and staff who work in a Bradford-managed location can use it as well; the Bradford registration form will automatically appear when a new computer plugs into the wired network at these locations and opens a web browser.
What can I do before I arrive on campus?
You can remotely register your computer through the Bradford Campus Manager (using the computer that you will be bringing to campus), and run through the scan to verify that you meet the network security requirements for access to the CUMC network. If you do not meet the requirements you will be provided with options on how to update and patch your computer. By registering your computer remotely before arriving on campus you will not be required to re-register your computer when you arrive.
What should I do if I get an error message from Bradford?
Read the message carefully. You will see a results page that will tell you specifically why the registration failed or if there are other types of errors. If registration failed for your computer due to it not having required security programs installed or updated, you will be able to go to web sites such as Windows Update and the Columbia licensed version of Symantec to be able to download and install them; other sites will not be available until you have successfully registered. After bringing your computer up to security requirements, you will be able to complete registration and connect.
If you still cannot register or don't understand the error, please call 5-Help (212-305-4357) while at your computer if possible and give us the specific error message you see in your web browser.
Why is a scan required?
Computer viruses and other types of malware (bots, worms, keyloggers, etc.) have increased to the point that if your computer is NOT up to date and protected, it can be infected within a VERY short period of time. New vulnerabilities in operating systems and third party software are found and exploited on a daily basis. A computer can be infected by simply visiting a website, one which may even be a legitimate site. When this happens, all student, faculty and staff computers on the network are affected. An infected computer will severely hinder all network traffic in addition to trying to infect all neighboring computers.
Much of the malware out there today attempts to steal personal information (banking details, credit card numbers, passwords, etc.). The updates we require will help your computer stay reasonably protected during your stay here and thus will allow all students the use of a much more secured shared resource - the campus network.
What happens if my computer fails the scan?
If you are on campus and it fails a Bradford Campus Manager scan, your computer will be quarantined (not allowed to access the network). If your computer is placed in quarantine, you will be provided with a web page that will allow you to download the needed software updates to meet campus security requirements and pass the scan. Once you have passed, your computer can then connect to the campus network and the Internet.
If you are not yet on campus, you will see a results page advising you which programs should be updated and/or installed. These must be done before you will be able to connect your computer to the campus network. Your computer will not be quarantined unless you are directly plugged into the network at CUMC.
What happens when my computer is connected at a Bradford-managed location?
Bradford Campus Manager runs periodic tests (every 7 days) on computers to determine compliance with security standards for CUMC's Safe Computing environment. Campus Manager may isolate your computer in a quarantine area of the network if it is not satisfied with the software configuration of your computer. The tests used may change over time, so passing security screening once does not guarantee your computer will always pass the tests, even if you make no changes to your operating system. When your computer fails testing, it will be quarantined and you will be provided an explanation for the quarantine and given instructions on how to take corrective action. For example, your computer will be quarantined if it has a virus, or if patches to your Windows or
Mac operating system are out of date.
What kinds of additional devices can I use on the CUMC network?
CUMC cannot allow routers or wireless access points on the network in part due to security issues. VoIP (voice over IP) is also not allowed on the network. Gaming devices can be registered by reading the instructions and submitting complete information on the
Register Your Console form from any computer.
Students are allowed to purchase dsl or high speed cable connections in their rooms for personal use, please contact the Student Housing Office and an Internet service provider if you would like to arrange for this.
Free high speed network access is a privilege given to CUMC students for academic use. The network is shared by CUMC offices and New York Presbyterian Hospital. Due to it being shared with NYPH, the network must also adhere to stringent HIPAA regulations. Our highest priority is that the network be kept secure and available for all to use.
How can I get my IP (network) address?
Please follow the steps on the Student Residential Network page to register your computer for an IP address. Student computers are set for dynamic (changing) IP addresses, which allow for connection at all CUMC campus network locations and continued connectivity if the network's configuration changes. Anyone requiring a static IP address must have specific academic reasons for this, please contact 5-Help with specific information or questions if needed.
Who assigns the IP addresses?
The group that manages the network for the entire CUMC and NYPH campus, CORE Resources,
assigns the IP addresses. Please remember that if you have any issues
or questions regarding the campus network you must first contact us at extension 5-Help, option 5 or come to the CUMC IT Service Desk.
How long does it take to get my IP address?
Wired access and a dynamic IP address are available within 2 hours of successfully registering via the Bradford form. You must pass the registration - including receiving a message that the registration was successful - in order to receive a (dynamic) IP address.
Can I choose an IP Address?
No, you may not choose your own IP address; see the Network Addresses and Naming policies page for details. Picking an IP Address has the potential to cause more harm than good. CORE
considers this to be stealing network resources and will block your computer on the network. A Security Incident Report will be created and
your computer will be blocked. A decision will then be made as to whether your connection can be reactivated or if further action will
be taken against you, in concert with your academic dean.
You must be sure to follow the instructions to register
your computer for use on the CUMC network. Because CUMC shares the network with New York Presbyterian Hospital and must comply with HIPAA
regulations, we must have current contact information for all systems that are on the campus network.
Should I configure a manual IP address?
Students must not configure a manual IP address on their computers. A dynamic (not manual) address is generally easier to use and allows for roaming if you have a laptop. Configuring a manual address on your computer without prior approval from the CUMC IT Service Desk and CORE Resources can cause a loss of connectivity on properly registered computers, and result in disciplinary action including the blocking of your system(s).
What is my network card's hardware address (aka Physical, Ethernet or MAC address) and how is it used to register my computer?
An ethernet card hardware or adapter address (also called a MAC address) is a unique, 12-digit, hexadecimal (0-9, A-F) number assigned by the ethernet card's manufacturer. The address or string of characters may be formatted as shown in these examples: 0260.8C3B.7A21 or 02:60:8C:3B:7A:21 or 02-60-8C-3B-7A-21. Because it is unique world wide, it this address is used to identify your computer
on the campus network.
All computers, regardless of their operating system, must be registered in order to be given access to the CUMC network. The Bradford registration form will automatically find your computer's hardware address and register it when scanning.
If you need to find the address for your network interface card it can be looked up via the computer's operating system. Select the link for your computer's operating system below for step by step instructions:
What if I replace my computer or its network card?
Please use the online form to re-register. Your computer is recognized on the campus network by a Hardware Address that is unique to every network card, so replacing this requires that it be registered again.
Do I need to buy anything to connect to the network?
Almost all computers have a built in network interface card. If your computer has network card, you are all set. You will also need
an Ethernet patch cable (also known as Cat-5 or Category-5 cable) if one did not come with the computer; these can be purchased at any store
that sells computer equipment. A network cable is thicker than a phone cord and has connectors on the end that look similar to phone connectors but are slightly
Who can I talk to if the network connection in my room isn't working?
If you have already registered your computer but can not get a network connection via the data port in your dorm or apartment, please call the CUMC IT Service Desk at extension 5-Help (212-305-4357). It is best if you are at your computer in your room when you call so the technicians can accurately troubleshoot the problem.
Where can I find the jack number in my room?
You can typically find the jack number written below the jack or data port.
Who can help me set up my computer connection from CUMC student housing?
If you need initial set up and registration for a network connection, please see our Student Residential Network page for easy, detailed instructions.
Technicians can answer any other questions you may have about the connection, please call us at (212) 305-Help, or come by the CUMC IT Service Desk on the 2nd floor of the library.
Who can I speak to if the connection in the dorms is down?
Call the Service Desk at extension 5-Help (212-305-4357).
How can I transfer files over the network?
- You can email a file as an attachment from your Columbia email account - an email including its attachment can be up to
3MB if using CubMail, or up to 20MB if using an email program such as Outlook or Apple Mail.
- You can use WinSCP (for PC) or
Fugu (for Mac) to upload and download files from your space on
the Columbia Cunix servers.
- If you are comfortable using a command line interface, you can also use an
SSH program (
Putty for PC or
Terminal for Mac) to transfer to and from your Cunix account.
Keep in mind that there is a 40MB limit on your Cunix space.
