Batch mode capture The typical procedure is to capture packets to a file and then examine the file on the desktop, as your strated below: CMD code ADB shell tcpdump-I any-p-S 0-W/sdcard/capture. pcap # "-I any": Listen on any network inte ** CE # "-P": Disable promiscuous mode (doesn' t work anyway) # "-S 0": capture the entire packet # "-W": Write packets to a file (rather than printing to stdout) ... Do whatever you want to capture, then ^ C to stop it... ADB pull/sdcard/capture. pcap. Sudo apt-Get install Wireshark # Or ethereal, if you're still on dapper Wireshark capture. pcap # or Ethereal ... Look at your packets and be wise... ADB shell tcpdump-I any-p-S 0-W/sdcard/capture. pcap # "-I any": Listen on any network inte ** CE # "-P": Disable promiscuous mode (doesn' t work anyway) # "-S 0": capture the entire packet # "-W": Write packets to a file (rather than printing to stdout) 　　 ... Do whatever you want to capture, then ^ C to stop it... ADB pull/sdcard/capture. pcap. Sudo apt-Get install Wireshark # Or ethereal, if you're still on dapper Wireshark capture. pcap # or Ethereal ... Look at your packets and be wise... You can run tcpdump in the background from an interactive shell or from terminal. by default, tcpdump captures all traffic without filtering. if you prefer, add an expression like port 80 to the tcpdump command line. Real Time packet monitoring Execute the following if you wowould like to watch packets go by rather than capturing them to a file (-N skips DNS lookups.-S 0 captures the entire packet rather than just the header ): CMD code ADB shell tcpdump-n-s 0 ADB shell tcpdump-n-s 0 Typical tcpdump options apply. For example, if you want to see http traffic: CMD code ADB shell tcpdump-X-n-s 0 port 80
