android 用tcpdump抓取网络包

Instructions 　　http://source.android.com/porting/tcpdump.html 　　Source Code and Documents 　　http://www.tcpdump.org/ 　　Compiled Binary Download 　　http://www.strazzere.com/android/tcpdump 　　数据包分析工具Wireshark 　　http://www.wireshark.org/download.html 　　Installing tcpdump 　　Pushing the binary to an existing device 　　Download tcpdump from http://www.tcpdump.org/, then execute: 　　Cmd代码 　　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代码 　　adb shell tcpdump -i any -p -s 0 -w /sdcard/capture.pcap 　　# "-i any": listen on any network inte**ce 　　# "-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 inte**ce 　　# "-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代码 　　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代码 　　adb shell tcpdump -X -n -s 0 port 80
