![]() ![]() If anything goes wrong, you will need to rerun both commands.įor more immediate output, add -l to the tcpdump command line, but this can cause adb to choke (it helps to use a nonzero argument for -s to limit the amount of data captured per packet -s 100 is sufficient if you just want to see headers). ![]() Note that you can't restart capture via ethereal. # In a separate shell, forward data and run ethereal.Īdb forward tcp:11233 tcp:11233 & nc 127.0.0.1 11233 | ethereal -k -S -i. You can also monitor packets with wireshark or ethereal, as shown below:Īdb shell "tcpdump -n -s 0 -w - | nc -l -p 11233" For example, if you want to see HTTP traffic: s 0 captures the entire packet rather than just the header): Real time packet monitoringĮxecute the following if you would like to watch packets go by rather than capturing them to a file ( -n skips DNS lookups. If you prefer, add an expression like port 80 to the tcpdump command line. By default, tcpdump captures all traffic without filtering. You can run tcpdump in the background from an interactive shell or from Terminal. Sudo apt-get install wireshark # or ethereal, if you're still on dapper do whatever you want to capture, then ^C to stop it. # "-w": write packets to a file (rather than printing to stdout) # "-p": disable promiscuous mode (doesn't work anyway) # "-i any": listen on any network interface The typical procedure is to capture packets to a file and then examine the file on the desktop, as illustrated below:Īdb shell tcpdump -i any -p -s 0 -w /sdcard/capture.pcap You need to have root access on your device. If you want to build tcpdump by default, add CUSTOM_TARGETS += tcpdump to your buildspec.mk. Make snod # build a new system.img that includes itįlash the device as usual, for example, fastboot flashball. Mmm external/tcpdump # install the binary in out/./system/xbin If you are running your own build, execute: There are some pre-built VMs designed for developers and the curious over on the Oracle Tech Network site.Running tcpdump Other network debugging commands Installing tcpdump Pushing the binary to an existing deviceĪdb push /wherever/you/put/tcpdump /system/xbin/tcpdumpĪdb shell chmod 6755 /data/local/tmp/tcpdump Please also take a look at our licensing FAQ, in particular regarding the use of the name VirtualBox. svn co vboxĪfter getting the sources in one of the ways listed above, you should have a look at the build instructions. ![]()
