There was a warning that some network cards would disassociate during monitor mode, which does make sense. Then I switched to monitor mode for that interface (see screenshot #3), and all I could see was radio traffic, not the IP within that radio traffic. I was also monitoring in 'ethernet' mode. (This makes sense, even though I was in promiscuous mode, the traffic was between the AP (access point), and the target wireless client.) This made sense, since I was monitoring the local interface, and the traffic from the target device wasn't flowing through my interface on the macbook. I was able to detect network traffic from my local computer to the URL in question, but when viewing the same URL from a different device, I was not able to see that device's traffic. Update for context and more information for I started this process, I used promiscuous mode on the en0 interface (wireless) on a macbook air. If this is the case, is there software to decrypt the data after it has been recorded?
If I need the passphrase, I have it (given that this is my lab network). What settings am I missing, or do I need to decode the WPA2 passphrase to view the data? I am also able to see and capture 802.11 packets using monitor mode, but I cannot see their content.
I have wireshark configured properly to capture on the wireless interface. I've seen this in action (ala firesheep) on a wired network. I'd like to demonstrate that unencrypted (non-HTTPS) network traffic on a wifi network can be viewed by other wireless devices. To set an interface to promiscuous mode you can use either of these commands, using the ‘ip’ command is the most current way.I'm attempting to replicate a 'wifi cafe' setup in a home lab environment. How to Manually set a NIC in Promiscuous Mode? In bridge network, the NIC is mostly required to operate in promiscuous mode.If a Network monitor tool is used, like tcpdump etc.If it was manually configured in that mode using ifconfig command.A network card usually is in promiscuous mode when: Suppose for eth1, promiscuous mode is basically used to pass all traffic that ‘eth1’ receives rather than just frames addressed to it. When a network card is in promiscuous mode, it can read all traffic it received rather than just packages addressed to it. Otherwise, deep investigation on that system will be required due to a security issue. If there was such program intentionally running or bridged networking for hardware virtualization, the “promiscuous mode” message might be simply ignored. It is usually used by a packet sniffing program like Wireshark, and tcpdump. Promiscuous mode or promisc mode is a feature that makes the ethernet card pass all traffic it received to the kernel.
