Android通過tcpdump抓包

1. 手機要有root權限

2. 下載tcpdump   http://www.strazzere.com/android/tcpdump

3. adb push c:\wherever_you_put\tcpdump /data/local/tcpdump

4. adb shell chmod 6755 /data/local/tcpdump

5, adb shell,   su獲得root權限

6， cd /data/local

7， ./tcpdump -i any -p -s 0 -w /sdcard/capture.pcap

命令參數：

 

        # "-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 ...

 

8,  adb pull /sdcard/capture.pcap d:/

9,  在電腦上用wireshark打開capture.pcap即可分析log

 

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):  

 

adb shell tcpdump -n -s 0   

 

Typical tcpdump options apply. For example, if you want to see HTTP traffic:  

只監聽http  

adb shell tcpdump -X -n -s 0 port 80

 

根據以上的信息，寫一個bat去執行（tcpdump文件必須在當前目錄裏）。

 

開始tcpdump 

adb push tcpdump /data/local/tcpdump

adb shell chmod 6755 /data/local/tcpdump

adb shell rm -r /sdcard/capture.pcap

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

pause

 

下載tcpdump文件到電腦 

 adb pull /sdcard/capture.pcap capture.pcap 

 

 問題：有些機器root後通過adb shell 後，默認不是root用戶，需要輸入 su才能切換到root，這樣在執行批處理會有問題，解決方法如下

adb shell "su -c 'sleep 1'"

adb start-server

adb push tcpdump /data/local/tcpdump 

 

 因沒有root權限導致的問題

adb shell su -c "/data/local/tmp/tcpdump -i any -p -s 0 -w /sdcard/netCapture.pcap"
