Using Virtual Ethernet Adapters in Promiscuous Mode on a Linux Host (287)
VMware software does not allow the virtual Ethernet adapter to go into promiscuous mode unless the user running the VMware software has permission to make that setting. This follows the standard Linux practice that only root can put a network interface into promiscuous mode.
When you install and configure your VMware software, you run the installation as root, and we create the vmnet0-vmnet3 devices with root ownership and root group ownership. We also give those devices read/write access for the owner root only. For a user to be able to set the virtual machine's network adapter to promiscuous mode, the user who launches the VMware product needs to have read/write access to the vmnetx device (/dev/vmnet0 if using basic bridged mode).
chgrp newgroup /dev/vmnet0
chmod g+rw /dev/vmnet0
where newgroup is the group that should have the ability to set vmnet0 to promiscuous mode.
chmod a+rw /dev/vmnet0
The virtual machines operating system has attempted to enable promiscuous mode on adapter Ethernet0. This is not allowed for security reasons.
/dev/, as above. .
