winpcap

There are two problems here: What if content is encoded:gzip... Do I also need to change the header part to make the HTTP packet valid(checksums if any?) UPDATE Can someone with actual experience elaborate the steps involved? I'm using winpcap and bpf tcp and src port 80 to filter the traffic,so my job lies in this callback function: void packet_handler(u_char *param, const struct pcap_pkthdr *header, const u_char *pkt_data) WinPcap doesn't allow you to change a packet that was already sent. If the packet was sent, WinPcap won't prevent it from reaching its destination. If you want to send

I just want to listen a network device, capture packets and write the packets to a dummy file. Also i need to filter packets while listening so ill only write packets which passes the filter. I need to do these on .net c#. These are my requirements. So which one should i use? High transfer rate and minimum packet loss is really important. Thanks for reading. As the author of SharpPcap I can say that you'll be able to perform all of those operations with the library. Performance was a critical design goal. Packet.Net has a range of packets that it can parse and is the library bundled along with

I've heard it's not possible with my current library of winpcap. Is this really true? I see lots of examples on the net but then comments saying "This doesn't work". What's the best way to get a MAC address of the local machine? One common method is using bits from a UUID, but this isn't entirely dependable. For example, it'll return a value even on a machine that doesn't have a network adapter. Fortunately, there is a way that works dependably on any reasonably recent version of Windows. MSDN says it only goes back to Windows 2000, but if memory serves, it also works on NT 4, starting around

I'm using browser automation for testing web sites but I need to verify HTTP requests from the browser (i.e., images, external scripts, XmlHttpRequest objects). Is there a way to programmatically instantiate a proxy or packet sniffer for the browser to use in order to see what its sending? I'm already using Fiddler to watch the traffic but I want something that's UI-less that I can use in continuous build integration. Can I easily get the HTTP-specific information from WinpCap? Try winpcap . It's a driver/library combination which can be used to monitor packets. Based on what you are trying to

wondering any of you can give me a bit of comments + insights please. In term of performance, which one should I use, jNetPcap or Jpcap? Thanks! The referenced post contains an admittedly biased opinion by the owner of the jNetPcap project. It is hardly a reliable source for a true comparison. One difference that is obvious between the two projects is that jNetPcap uses JNI for access to native code. PCap4j ( http://www.pcap4j.org/ ) uses JNA for access to native code and a "com.sun" JNA compatibility library ( https://github.com/twall/jna ). Also, the latest version of jNetPcap does not build

What direction should I go in( libraries , documents )? UPDATE Can someone illustrate how to use winpcap to do the job? UPDATE 2 How do I verify whether a packet is an HTTP one? If by "hijack" you meant sniff the packets then what you should do to do it with WinPcap is the following: Find the device you want to use - See WinPcap tutorial . Open a device using pcap_open // Open the device char errorBuffer[PCAP_ERRBUF_SIZE]; pcap_t *pcapDescriptor = pcap_open(source, // name of the device snapshotLength, // portion of the packet to capture // 65536 guarantees that the whole packet will be
