Installing tcpdump
 
Pushing the binary to an existing device 
Download tcpdump from http://www.tcpdump.org/, then execute: 
Cmd代码  技术分享
  1. adb root  
  2. adb remount  
  3. adb push /wherever/you/put/tcpdump /system/xbin/tcpdump  
  4. 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:

  1. adb shell tcpdump -i any -p -s 0 -w /sdcard/capture.pcap  
  2. "-i any": listen on any network interface  
  3. "-p": disable promiscuous mode (doesn‘t work anyway)  
  4. "-s 0": capture the entire packet  
  5. "-w": write packets to a file (rather than printing to stdout)  
  6.   
  7.    ... do whatever you want to capture, then ^C to stop it ...  
  8.   
  9. adb pull /sdcard/capture.pcap .  
  10. sudo apt-get install wireshark  # or ethereal, if you‘re still on dapper  
  11. wireshark capture.pcap          # or ethereal  
  12.   
  13.    ... 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):

  1. adb shell tcpdump -n -s 0  


Typical tcpdump options apply. For example, if you want to see HTTP traffic: 
Cmd代码  技术分享
  1. adb shell tcpdump -X -n -s 0 port 80
