在Android手機上實現tcpdump抓包

1. 手機要有root權限

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

3. adb push E:\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

根據以上的信息，寫一個bat去執行

adb root

pause

adb remount

adb push E:\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

adb pull /sdcard/capture.pcap E:\capture.pcap

pause

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
