As OSX no longer allows
ifconfig en0 promisc and sees that as a bad value and does not set the device flag, what other options are there? I'd like to be able to boot and have both my Airport/WiFi as well as any ethernet/thunderbolt/usb ethernet devices come up in promiscuous mode automatically before login...at boot.
I see that upon running
tcpdump etc within the system puts the devices in promiscuous mode as seen from an
promisc flag under whatever device I'm capturing.
How can I acheive promiscuous mode on boot? I need this for testing specific login issues at the login window for 802.1x Cisco ISE. Any further information on the matter is very much appreciated.
