　　Installing tcpdump

　　Pushing the binary to an existing device

　　Download tcpdump from http://www.tcpdump.org/, then execute:

　　Cmd代碼

　　adb root

　　adb remount

　　adb push /wherever/you/put/tcpdump /system/xbin/tcpdump

　　adb shell chmod 6755 /data/local/tmp/tcpdump

　　adb root

　　adb remount

　　adb push /wherever/you/put/tcpdump /system/xbin/tcpdump

　　adb shell chmod 6755 /data/local/tmp/tcpdump

　　Running tcpdump

　　You need to have root Access on your device.

　　Batch mode capture

　　The typical procedure is to capture packets to a file and then examine the file on the desktop, as illustrated below:

　　Cmd代碼

　　adb shell tcpdump -i any -p -s 0 -w /sdcard/capture.pcap

　　# "-i any": listen on any network interface

　　# "-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 interface

　　# "-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 would 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代碼

　　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代碼

　　adb shell tcpdump -X -n -s 0 port 80
