Hello, I think I am working on solution for you... If you have ADB (SDK) and tcpdump (with permissions) then I can emulate live capture from Android devices. Please check: adb shell tcpdump -D adb shell su -c "tcpdump -D"
Before you attempt to use the output of `adb shell` in a pipe, keep in mind that adb mangles newlines (LF -> CRLF) and is therefore unsuitable for binary data. This does not matter for textual output such as "tcpdump -D", but it affects "tcpdump -w -" (writes pcap to stdout).
Limitation: works only with Wireshark, or standalone application, not Windows Interface.

Is it possible to enumerate phone over adb interface as device wireless network interface in Win7 machine and configure it in promiscous mode for sniffer application?
I have once written an Android app which can put a wireless interface in promiscuous mode and capture layer 2 frames (802.11). There are some issues to consider: - The wireless driver of my phone did not support monitor mode. So I bought a USB on the go cable and a Ralink 802.11n USB adapter using the rt2x00 driver. This driver was not supported by the custom firmware (Cyanogenmod) so I had to build a new kernel as well. - The easiest way to make use of tcpdump is by running it as root, but you can also use capabilities and declare a manifest permission in the Android app. (This required a kernel patch, http://stackoverflow.com/q/13042117/427545). - Battery drains fast when using an external USB adapter, phone can get quite hot. - If your firmware does not include tcpdump, it is actually quite easy to build it. All you need are the libpcap and tcpdump sources and the Android NDK. Oh and it is not trivial to build Wireshark for Android. It has many dependencies, and last time I looked using dumpcap/tshark, I stopped once it notes that Glib was missing. If you just want to debug an app on the phone, it is much easier to setup a VPN/proxy and start tapping at the VPN or proxy server. -- Kind regards, Peter Wu https://lekensteyn.nl ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
