VMWare Networking

Due to the security implemented on the hubs in the Residential Network, your port will be disabled if VMWare is used with a changing Ethernet address (this is the factory default).

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, and enter this into the VMware config file as follows:

# networking bridged to real ethernet
# ethernet0.present = TRUE
# ethernet0.connectionType = bridged
# ethernet0.address = 00:50:56:xx:xx:xx

If you expect to be using VMware networking on the WPI ResNet, 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 used VMware MAC addresses on the CCC UNIX systems with the following command:

grep 00:50:56 /shared/stations/etc/ethers

You should change the address for your VM, using the NetReg page, to one that meets the above criteria.

Once you update the web page, it will take up to one business day until the security on the hub is updated to reflect your changes. You will receive a confirmation e-mail when this is done. Don't forget to update your VMware configuration file as well.

Failure to do this will result in your port being locked out the next time you run VMware with a dynamic Ethernet address.

You can find more documentation on this topic on the VMWare Support page.
