View Full Version : Disable Promiscuous Mode?

Nov 12, 2012, 12:47 AM
Hi All,

I haven't been able to get on my campus' network since the start of the semester, their IT team (low-level) couldn't figure it out after an hour of toying around. I can log onto the network from any other device, but it appears my MAC address might be blocked. I am in a networking class, so I was trying out WireShark on my home network awhile ago (I live alone but have plenty of devices running on the network) to see how it works. I tried running a command in the terminal to disable promiscuous mode, it said "bad value" for sudo ifconfig en1 -promisc, so clearly I am missing something.

Partial output for sudo ifconfig en1 is:

It appears PROMISC mode is turned on for my MacBook Pro's (10.8) built in WiFi (Airport). How do I disable PROMISC? I didn't see an option in WireShark.

Also, no I am not trying to snoop on people. My professor mentioned WireShark in a lecture at the beginning of the semester in my computer networks class.

Thanks in advance,
