Ips af-packet threads number not equals
WebJun 25, 2024 · Thread-modules are specific thread functionalities, like decode or detect. A packet can be processed by more than one thread and queues are responsible for passing the packet from one thread to another. When those three elements combined work together in packet processing, they become a runmode. WebIf IP_HDRINCL is not enabled, for sending, the packet must contain the IP header, the TCP/IP stack will not generate this for you. All other upper layers can be received by this socket. Secondly, s = socket(AF_PACKET, SOCK_RAW, 0);: This is a special type of Raw Socket and called Packet-socket in Linux system.

Webs = socket.socket (socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_RAW) socket.IPPROTO_RAW gives you access to Level 3 protocol (IP), whereas ethernet is on Level 1 and 2. At level 3 an ethernet frame is already analyzed and its headers discarded. You need to get to Level 2 and ETH_P_ALL protocol seems to be a nice place to start.
