Android tcpdump is a command line packet capture utility. It can capture packets from your Wi-Fi connection, cellular connections, and any other network connections you may have on your android device. It has been compiled from the source code located at http://www.tcpdump.org. If you use linux's or unix's tcpdump application, then you will be familiar with Android tcpdump because it has the same switches and options as its linux's counterpart. The compiled version is sometimes referred to as tcpdump-arm because most Androids, more than 95%, run on the ARM architecture.
To use this application, you need to have:
Root access is a mod performed on the Android device to allow you to run applications at a superuser level. We will not go into the details on how to root your device on our site. There are many discussion groups / sites showing the how-to's to root your device. Needless to say, tcpdump needs to be run at a superuser level, so your device needs to be rooted. Note: Rooting your device could void its warranty.
Since tcpdump is a command line tool, you will require terminal access on your device. There are plenty of terminal access programs for the Android. Just go to the Play Store on your device, and search for Terminal Emulator, or Shell Terminal, or Command Prompt, and this will bring you to a suitable shell prompt.
Terminal access can also be from a tethered computer. If you have ADB (Android Debug Bridge), an option to connect is via the adb shell command, giving you access to a shell on your Android device from your PC.
Don't forget to "su" to superuser before you run tcpdump, otherwise you will receive a warning, "tcpdump: can't execute: Permission denied"
This is what our site offers - tcpdump for Android. The binary, or executable is the command line tool you will be running. After you have downloaded the binary to your device you will need to change the file permissions of the file to make it executable. (ie chmod +x tcpdump. You can then run the program by typing in './tcpdump'.
