-py2.7.rarThe following code shows how to use Scapy to complete pcap reading and writing, and provides a picklablepacket class for solving the problem of scapy parsing packet cannot be serialized, the code is as follows:Importscapy fromScapy.allImport* fromScapy.utilsImportPcapreader, PcapwriterImportGzip,zlib,cpickleclassPicklablepacket:" "A container for scapy packets so can be pickled (in contrast to scapy pakcets themselves)" " def __init__(sel

This is a simple analysis of their own pcap file, easy to read Pcap file, we refer to the use of the bar Copy Code code as follows: InputStream is = DataParser.class.getClassLoader (). getResourceAsStream ("Baidu_cdr.pcap");

Preface The data structure has already been defined, so it's time to formally parse the Pcap file.Note: The following only the core code, the project all the code will be at the end of the article to give the download link Resolution pcap file 1 Read the entire Pcap

packet sent by the client PSH (1 bit): Push function, request to push buffered data to the receiving application RST (1 bit): Reset connection SYN (1 bit): Sync serial number. This flag should be set only for the first packet sent from each end. Some other flags and fields change meaning according to this flag, some only work when set 1 o'clock, while others are only valid at 0 o'clock FIN (1 bit): Last packet from sender Window size (BITS): The size of the receive

Pcap is a data packet capture library, which is used by many software as a data packet capture tool. Wireshark also uses the pcap library to capture data packets. The packets captured by pcap are not the original network byte streams, but are assembled to form a new data format.The file format of a data packet captured

HTTP packets in the PCAP package can be easily parsed using scapy, scapy_httpScapy_http can be downloaded in https://github.com/invernizzi/scapy-http, the address is also given a simple example program, according to this sample program I modified an output PCAP packet in the source destination address of the HTTP packet, The payload applet is as follows:where P is a packet, scapy_http divides it into:Ethern

The pcap file format is the format in which BPF saves the original data packets. Many software applications are used, such as tcpdump and Wireshark. Understanding the pcap format can enhance understanding of the original data packets, you can also manually construct any data packet for testing. The pcap

For example, 1 in decimal format indicates Ethernet, 6 indicates the ring-based network, and 15 indicates the hardware format of Frame Relay. Generally, in an Ethernet environment, the four bytes are 01 00 00. The above fields are part of the file header, followed by data packets. Each packet has a corresponding 16-

Block Value (variable length) The block value content transmits the actual information in the block. The content is determined by the message block type. The length of the block value is not long.Sctp struct Definition // Sctp header typedef struct _ sctp_header {_ int16 srcport; _ int16 dstport; _ int32 ivertag; _ int32 ichecksum;} _ sctpheader; // chunk
