VMWare Fusion locks up when entering promisc mode

Question

Using the following command will result in the VM guest locking up;

ifconfig eth0 promisc

Answer 1

After reading more docs, it seems that VMWare Fusion requires user authentication when a guest machine enters promisc mode. This should result in a user dialog popup, but doesn't seem to happen.

As a temporary work around you can untick the "Require authentication to enter promiscuous mode" box in "Preferences > Network", but should only be used if you trust every guest VM.
