Installing tcpdump
Pushing the binary to an existing device
Download tcpdump from http://www.tcpdump.org/, then execute:
Cmd代码

adbroot
adbremount
adbpush/wherever/you/put/tcpdump/system/xbin/tcpdump
adbshellchmod6755/data/local/tmp/tcpdump

adb rootadb remountadb push /wherever/you/put/tcpdump /system/xbin/tcpdumpadb 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

adbshelltcpdump-iany-p-s0-w/sdcard/capture.pcap
#"-iany":listenonanynetworkinterface
#"-p":disablepromiscuousmode(doesn'tworkanyway)
#"-s0":capturetheentirepacket
#"-w":writepacketstoafile(ratherthanprintingtostdout)
...dowhateveryouwanttocapture,then^Ctostopit...
adbpull/sdcard/capture.pcap.
sudoapt-getinstallwireshark#orethereal,ifyou'restillondapper
wiresharkcapture.pcap#orethereal
...lookatyourpacketsandbewise...

adb shell tcpdump -i any -p -s 0 -w /sdcard/capture.pcap# "-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 ...adb pull /sdcard/capture.pcap .sudo apt-get install wireshark  # or ethereal, if you're still on dapperwireshark 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

adbshelltcpdump-n-s0

adb shell tcpdump -n -s 0

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

adbshelltcpdump-X-n-s0port80

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