Subject: [Snort-devel] Packet Capturing

I am a newbie of Snort IDS. I installed Snort on ubuntu. I want to sniff packets from all the devices connected to wifi router and get alerts based on some rules I defined. I manually setup NIC to promiscuous mode. My problem is that I cannot sniff packets of other devices. Am getting packet information of only laptop on which Snort is running.

I used following command:

$ sudo snort -c  snort.conf -A console -i wlan0
