wireshark

System Setup:
1. MacBook running Mountain Lion.
2. Wireshark installed and capturing packets (I have "capture all in promiscuous mode" checked)
3. I filter out all packets with my source and destination IP using the following filter ("ip.dst != 192.168.1.104 && ip.src != 192.168.1.104")
4. On the same network as the MacBook, I use an Android device (connecting via WiFi) to make HTTP requests.

Expected Results:
1. Wireshark running on the MacBook sees the HTTP request from the Android device.

Actual Results:
1. I only see SSDP broadcasts from 192.168.1.1

Question:
What do I need to do so that Wireshark, like Firesheep, can see and use the packets (particularly HTTP) from other network devices on the same network?

Saving Wireshark capture settings for future use

Is there any way to save Wireshark capture options? So it can be reuse after restart Wireshark. Also, if the saved file is in plain text, it's possible to use scripts generating bunch of capture settings, such with different filter setting. Does anyone know? Thanks. >>> More
