How To Gain Access To The Network in SCS

Gaining access to the network in SCS for Windows and Mac.


To get access to the SCS Network: 

Every computer must be registered in order to be allowed access to the wired internet in buildings managed by the School of Chemical Sciences IT. 

As of December, 2022, the wired network is reserved for University-owned devices. If your personal device needs a wired connection, we will judge on a case by case basis whether to grant access.

To initiate the process of registration, visit

You will need the following information: 

  • Building and Room Number:  
  • Label of Network Jack (e.g. HAP01-01):  
  • PI/Supervisor:  
  • Type of Device (Laptop, Desktop, etc.):
  • Make / Model of computer (e.g. Dell Latitude 5500)
  • Is this computer owned by the University? If not, explain why your personal device needs a wired connection
  • Operating System (edition and version) of Computer:

    • Windows:  Example:  Windows 10 Enterprise v22H1
      • To get this:  Press the Windows key, type About, and select "About your PC".  

    • Mac:   Example:  MacOS Big Sur v11.6.1
      • To get this:  Click on the Apple menu in the corner of your screen, and choose "About This Mac".

    • Linux:    Example: "CentOS 7.7". 
      • To get this, type lsb_release -a.  This should work on most distributions.  

  • MAC Address of Network Adapter:  

How to Find your MAC (medium access control) Address if you don't know it: 

Note about MAC addresses:  Every network adapter (whether that be USB, on-board, expansion card, etc) has a globally unique number that identifies it. This means that a computer that has both a wired and wireless adapter, then each adapter will have its own MAC Address. Make sure you provide the correct address or the registration will not work.
SCS Computing generally only registers USB network adapters for faculty and staff.  


  1. Open a command line by pressing the windows key and typing cmd and hitting 'Enter' (this should bring up a Command Prompt)
  2. Type the command: getmac /v
  3. Find the line titled "Ethernet" (in red)
  4. Get the physical address listed for your wired connection (in yellow)

On most Linux distributions, you should be able to type ifconfig -a.

The wired ethernet adapter will generally be called "eth0".  

On the first line, you'll see the "HWaddr", which will be followed by 12-digit hex code (0-9, A-F) that will look like: A1:B2:C3:D4:E5:F6.  It may be all numbers, or a combination of letters and numbers.
