-F
Set the built-in filter expression for capturing
-G
After you use the-r parameter to read the captured file, use this parameter to jump to the package of the specified number.
-H-H option: Request Wireshark
example:
# Tcpdump-w google. cap
This command stores the packet capture results in the google. cap file. You can use Wireshark to open and view the results. Colleagues, tcpdump out of the packet capture, you can also use the-r parameter to develop the packet capture data file, combined with the filter for packet
, select the record of get/tankxiao HTTP/1.1, right-click and click "follow TCP stream ",
The purpose of this operation is to obtain the data packets related to opening the website in a browser.
As shown in the figure, Wireshark intercepts three data packets of three handshakes. The fourth packet is HTTP, which indicates that HTTP uses TCP to establish a connection.
First handshake packet
The client sends a TCP packet. The flag is SYN and the serial
result to a file, for example:
# Tcpdump-w google. cap
This command stores the packet capture results in the google. cap file. You can use Wireshark to open and view the results. Colleagues, tcpdump out of the packet capture, you can also use the-r parameter to develop the packet capture data file, combined with the f
for packet capture data analysis, such:
# Tcpdump-r Google. Cap HTTP
This command allows tcpdump to read the Google. Cap file and filter out all HTTP data packets. Filters are described in detail below.

Wireshark is a very useful packet capture tool. When we encounter network-related problems, we can use this tool for analysis. However, it should be noted that this is just a tool, the usage is very flexible, so the content described today may not help you solve the problem directly, but as long as you have the idea of solving the problem, learning to use this software is very useful.Wireshark http://www.wi

Wireshark is a very popular network packet analysis software with powerful functions. You can intercept various network packets to display the details of network packets.
Wireshark is an open-source software that can be safely used. It
By default, the root permission is required to access the network port, while Wireshark only requires a UI of/usr/share/dumpcap, and/usr/share/dumpcap requires the root permission, therefore, non-root users cannot read the NIC list.
The solution is simple. sudo Wireshark
