Wireshark packet capture Analysis of TCP establishment and disconnection Process 1. Establish a connection over TCP Note: In this figure, Hosta acts as the client and hostb acts as the server. TCP is the transport layer protocol in the Internet. It uses the three-way handshake protocol to establish a connection. When the active Party sends a SYN connection request, wait for the other party to answer SYN, A

1. Enable the rpcapd service on the remote host Take windows as an example. Check that Winpcap has been installed, switch to the Winpcap directory, and run Rpcapd-B IP address-P port number-l IP address of the host that allows remote packet capture-n The specific usage of rpcapd can be queried through rpcapd-H. 2.

Tag: Option packet double quotation mark host NetworkWireshark capturing packets that have been specified by IPCapturing the filter capture before it is set in Capture option, capturing only eligible packages, can avoid generating large capture files and memory footprint, but does not fully replicate the network environment when testing.Host 192.168.0.1//Fetch all packets received and sent by 192.168.0.1SRC host 192.168.0.1//source address, all packet

I. IP address filtering: the source IP address or target IP address is equal to an IP address.For example, IP. src addr = 192.168.0.208 or IP. src addr eq 192.168.0.208 displays the source IP address.IP. dst ADDR = 192.168.0.208 or IP. dst addr eq 192.168.0.208 display target IP Address Ii. Port Filtering:For example, TCP. Port EQ 80 // both the source and target ports are displayed.TCP. Port = 80TCP. Port EQ 2722TCP. Port EQ 80 or UDP. Port EQ 80TCP. dstport = 80 // display only the target port

Wireshark basic introduction and learning TCP three-way handshake, wiresharktcp This article introduces wireshark, a useful packet capture tool, to obtain network data packets, including http, TCP, UDP, and other network protocol packets.
