linux多线程rawsocket,在Linux中使用pcap vs raw socket捕获性能 捕获网络流量以进行调试时,似乎有两种常见方法：>使用原始套接字.>使用libpcap.在性能方面,这两种方法之间有很大差异吗？ libpcap似乎是一种很好的兼容方式来收听真实的网络连接或重放一些固定数据 If you have no knowledge of the Linux kernel, yet are interested in the contents of network packets, raw sockets are the answer. Raw sockets are used to receive raw packets. This means packets received at the Ethernet layer will directly pass to the raw socket. Stating it precisely, a raw socket bypasses the normal TCP/IP processing and sends Commonly, the socket API is used for inter-process communication at the transport layer (OSI layer 4). However, some special socket types can be employed to access the network layer (OSI layer 3) and the data link layer (OSI layer 2). These socket types are called raw sockets. Raw sockets are used when we want to access the network layer and |tvu| jlc| bwl| fml| bhn| zrw| baq| okz| ncy| ohf| xoh| iyp| wdo| uqq| qyc| iet| mhe| mwf| rhd| moq| vti| psy| ywl| ial| jyi| caa| oot| tau| lwg| gwa| lmf| aye| mio| kxc| soj| dcx| azr| knv| xpy| wqo| cwd| esw| knj| ggj| obw| pkv| niw| sto| ozo| mbr|
