Using VMware on the Network
VMware is a popular PC emulation program that is known to cause issues on the WPI network due to its default dynamic MAC address generation.
VMware supports two Ethernet addressing modes. In dynamic mode, VMware picks a random Ethernet address not currently being used on the LAN from the range 00:50:56:80:00:00 to 00:50:56:ff:ff:ff. In the static Ethernet address mode, you assign an Ethernet address to each VM from the range 00:50:56:00:00:00 to 00:50:56:3f:ff:ff. The WPI network, however, will only assign an address to a pre-regstered MAC address.
The fix for this is to use static mode. Static mode can be configured by adding a configuration block like this into the VMware configuration file:
# networking bridged to real ethernet ethernet0.present = TRUE ethernet0.connectionType = bridged ethernet0.address = 00:50:56:xx:xx:xx
You can find the documentation on this at VMWare's Bridged Networking docs.
If you expect to be using VMware networking on the WPI network, you will need to pick an unused static VMware Ethernet address and change your current VMware Ethernet address to that. You can find all the currently used VMware MAC addresses by using the Search function of NetReg to search for all VMware addresses currently registered.
You should change the address for your VM using the Network Registraion page to one that meets all of the above criteria. Don't forget to update your VMware configuration file as well.
Note: Any changes you make do not take effect until approximately 30 minutes after the form is submitted.Maintained by email@example.com
