libpcap

I've been doing a lot of attempts to get libpcap compiled for Android, and I don't see any pattern or any progress worth writing down. I have a very simple sniffer (that works fine in a MIPS linux) that uses libpcap, so I thought to myself oh, ok... no biggie... I'll just compile libpcap for Android (in the end, Android is just a Linux)... and here's where the problems started. I have no idea on how to compile libpcap using ndk-build and the Android.mk and all that infrastructure. I have the Android NDK in a directory. That NDK has the toolchains built (I have a lot of directories under ~

I found a traffic monitoring application for Android, Shark: http://sourceforge.net/projects/prueba-android/ which is based on JnetPcap and has a file with all the source files and the appropriate Android.mk files. I put the jni directory in the samples file of the Android-NDK and I tried to build it using ndk-build -C. During the compilation occurs some errors. Here is the error log I take: make: Entering directory `/home/thanasis/android-ndk-r5b/samples /jnetpcap_pure/jni' Compile thumb : jnetpcap <= util_crc16.c Compile thumb : jnetpcap <= util_crc32.c Compile++ thumb : jnetpcap <= jnetpcap

I need to save UDP packets to a file and would like to use the pcap format to reuse the various tools available (wireshark, tcpdump, ...). There are some information in this thread but I can't find how to write the global file header 'struct pcap_file_header'. pcap_t* pd = pcap_open_dead(DLT_RAW, 65535); pcap_dumper_t* pdumper = pcap_dump_open(pd, filename); struct pcap_file_header file_hdr; file_hdr.magic_number = 0xa1b2c3d4; file_hdr.version_major = 2; file_hdr.version_minor = 4; file_hdr.thiszone = 0; file_hdr.sigfigs = 0; file_hdr.snaplen = 65535; file_hdr.linktype = 1; // How do I write

For a Computer Science Information Warfare class a few years ago I wrote a python script that ran on libpcap promiscuous packet capture files to parse out facebook chat traffic (earlang tuples passed in clear text), and thought an interesting project would be to port the program to Android. I would like to rewrite it in Java but can't find any information about packet capturing directly on the handset. As far as I'm aware, there is no way to put the Wifi NIC into monitoring mode from the public API. However, depending on the device used by the phone, you may be able to get the system to put it

I'm trying to use libpcap in python3 using ctypes. given the following function in C pcap_lookupnet(dev, &net, &mask, errbuf) in python I have the following pcap_lookupnet = pcap.pcap_lookupnet mask = ctypes.c_uint32 net = ctypes.c_int32 if(pcap_lookupnet(dev,net,mask,errbuf) == -1): print("Error could not get netmask for device {0}".format(errbuf)) sys.exit(0) and the error i get is File "./libpcap.py", line 63, in <module> if(pcap_lookupnet(dev,net,mask,errbuf) == -1): ctypes.ArgumentError: argument 2: <class 'TypeError'>: Don't know how to convert parameter 2 how do you deal with &blah

I've been working on a way to have an OpenWRT router log WiFi probe requests to a MySQL db (it stores MAC address and RSSI info for each probe request packet along with other, router-specific data). After researching libpcap quite a bit, I've been able to cobble together a basic little program that simply sniffs packets on a monitor interface (mon0) using a filter expression ('wlan subtype probe-req') and then prints out the raw packets in hex. With the info that's available online on libpcap this part was fairly straightforward. Now here's where I'm stuck: How do I parse the WiFi packet to
