Connecting to the "Wired" Network

Staff and research students can apply to connect their Mac laptops to the School's laptop/self-maintained wired network. Please note that these networks are behind a firewall (see the network restrictions page for details).

Registering your Laptop

To register your laptop, please send an e-mail to support with the following information:

  • The Ethernet Address of your network adaptor
  • The Hostname of the laptop (if set)
  • The Operating System (Mac OS X)
  • The Serial Number of your laptop (if known)
  • The Port Number in the floor box where you wish to connect. If possible, select the next port number down from where your desktop machine is connected. Do not use the first port in the floor box as these are usually reserved for telephones.

Note: Please contact the Technical Workshop if you require any assistance with selecting a port number or connecting to the floor box.

Discovering the Ethernet Address

There are a number of ways to find out the ethernet address of your laptop. The easiest method is to look at the System Profile for your laptop

  1. Run the System Profiler from the Utilities folder (in the Go menu of Finder or under Applications/Utilities on the Hard Drive)
  2. Click the Network tab from the menu on the left of the Window
  3. Click Built-in Ethernet (interface en0)
  4. The Ethernet Address is displayed in the bottom half of the window (string of six hex numbers)

Alternatively, you can use the UNIX command ifconfig from a terminal window e.g. ifconfig -a will display information about all the network interfaces installed.

Configuring Network Settings

Once the laptop has been registered on the network, the network settings for the built-in ethernet adaptor need to be set. Very little configuration is necessary since everything will be provided by DHCP.

To check that the ethernet adaptor is configured for DHCP:

  1. Open the Network pane of the System Preferences
  2. Select Built-in Ethernet and click Configure...
  3. Click the TCP/IP tab
  4. The Configure IPv4 menu should be set to Using DHCP. Everything else should be left blank.
  5. If you have successfully connected to the network, you should see values for the IP Address, Subnet Mask, Router, etc...
  6. To access external web pages you will also need to configure the Proxies settings (see the proxies page for more details).

Note: If you use different network settings at home e.g. a static IP address, we recommend creating a new network location for the settings used in the School. You can change your network settings by simply swapping between your "home" and "School" locations.

  • To create a new location, select New Location... from the Location menu in the Network pane. The TCP/IP settings are set as described above.
  • To swap locations, simply select the location from the location menu in the Network pane or from the "apple" menu in the toolbar.

Note: If you have used DHCP on another network, you may need to renew your lease. Click the Renew DHCP Lease button in the TCP/IP tab of the network settings.
