Getting started with Linux: How to Use tcpdump to capture tcp syn, ACK, and FIN packets
Q: I want to monitor TCP connection activities (for example, three handshakes for establishing a connection and four handshakes for disconnecting ). To accomplish this, I only need to capture TCP control packets, such as SYN, ACK, or FIN flag related packets. How can I use tcpdump to

Some of the most recent difficulties in learning JavaScript, such as bubbling and capturing, have been mentioned many times, but I don't know where to apply it. Found some good Article FAQ, here to share with you.
Event bubbling and event capture were presented by Microsoft and Netscape, both of which were designed to address the issue of the event flow (sequence of events) in the page.

Function 1:PCAP_NEXT_EX (pcap_t* p,struct pcap_pkthdr** Pkt_header,Const u_char* Pkt_data)Read a packet from a network interface or offline capture method (such as a read file). The function is used to regain the next available packet without using the traditional callback method provided by Libpcap. PCAP_NEXT_EX assigns a value to the Pkt_header and Pkt_data parameters with pointers to the head and the next captured packet.The return value has the fo
Previously, I usually connected to my iMac through WiFi, and then used httpscoop or Charles for data capture and analysis. The former is very easy to use. The necessary tool for protocol adjustment is that the update process is too slow and the version 2.0 is too old. The latter has never been used. I heard it is Java. And the price is too expensive, the former is 15 US dollars, and the latter is 50 US dollars.

Therefore, it is necessary for us to fully understand the running process of Trace
