Android通过tcpdump抓包

1. 手机要有root权限

2. 下载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获得root权限

6, cd /data/local

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

命令参数:

        # "-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,  在电脑上用wireshark打开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:  

只监听http  

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


根据以上的信息,写一个bat去执行(tcpdump文件必须在当前目录里)。


开始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

下载tcpdump文件到电脑

adb pull /sdcard/capture.pcap capture.pcap


问题:有些机器root后通过adb shell 后,默认不是root用户,需要输入 su才能切换到root,这样在执行批处理会有问题,解决方法如下

adb shell "su -c 'sleep 1'"
adb start-server

adb push tcpdump /data/local/tcpdump


因没有root权限导致的问题

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