Netstat Command Overview:
Netstat is a very useful tool for monitoring TCP/IP networks, which can display routing tables, actual TCP network connections, TCP and UDP snooping, process memory management, and status information for each network interface device. The netstat is used to display statistics related to IP, TCP, UDP, and ICMP protocols, and is typica

Have you noticed the use of Netstat TCP while learning about TCP? Netstat is a very useful function that displays a lot of important information. Now let's take a closer look at this content. First, let's take a look at the role of Netstat.

Linux Many services are related to the network, when the service is not available or the start port is occupied, or is blocked by the firewall, you need to query the network-related problems, netstat command will only use one or two parameters here, a good study.
A few common options:
-A (All) displays all options and does not show listen related by default
-T (TCP) displays only TCP-related options
-U (UDP) displays only UDP-rel
The netstat command is used to print the status information of network systems in Linux, allowing you to know the network conditions of the entire Linux system.-A (All) displays all options and does not show listen related by default-T (TCP) displays only TCP-related options-U (UDP) displays only UDP-related options-N refuses to display aliases, showing all numbers converted to numbers-l list only service status in Listen (listening)-P Displays the pr

In some special monitoring modulation, we can monitor the status of Netstat TCP. The Netstat workgroup in Windows provides this function. Next, let's take a look at how Netstat outputs monitor the TCP connection status. Then, let's analyze the specific indicators.
You can monitor the TCP connection status in the network trace under the
In this case, you can run the netstat-nlutp command to check whether the dhcp service has enabled netstat and check the connected service port (ESTABLISHED) netstat-a to view all service ports (LISTEN, ESTABLISHED) sudonetstat-ap: View all service ports and Display corresponding ports...
At this time, you can run the "netsta

In linux, netstat is generally used to view system port usage.The netstat command is a very useful tool for monitoring TCP/IP networks. It can display the route table, the actual network connection, andThe
The netstat command is a useful tool for monitoring TCP/IP networks. It displays the route table, the actual network connection, and the status information of each network interface device. The following describes the implementation of the Linux testing tool netstat.
After running the Linux test tool netstat on a computer, the output result is as follows:

Because recently took over the project is based on the embedded Linux OpenWrt, initially thought will be with the previous server development no big difference, but encountered the problem to analyze the time only found that the tool chain is still some difference, OpenWrt's netstat belongs to a toolset called BusyBox, which is specifically provided to the embedded Linux, and its parameters are simple, there is no Linux under the
, You can disable the service by entering "Etstart" directly in the Command Prompt window to view the service, and then "Netstopserver" to prohibit the service.
3. Detect Network Connection
If you suspect that your computer is poisoned or someone has been implanted in a trojan, you can use the Netstat command to detect who is connected to your computer. The specific command format is: netstat-an, this com

The author is constantly in touch with this command during his work, therefore, this article has been specially developed, prepared, and started. This article mainly records some of the operating commands you encounter in Linux/UNIX at ordinary times, record and sort them out, one can
The netstat command is commonly used in network monitoring. You can use this command to view the services and established services monitored by the current system, as well as the corresponding ports and protocols.

Although TCP is recognized as a security protocol, it is essential for us to monitor it. Here we recommend some use of Netstat TCP. Next let's take a look at the specific content to learn how to manage Netstat TCP.
You can monitor the TCP connection status in the network trace under the Netstat TCP flag. You may also check the connection status by running the
First, netstat parameter explanation:
Netstat is used to display statistical data related to IP, TCP, UDP, and ICMP protocols, and to verify network connectivity for each port on the machine. The Linux terminal uses the NETSTAT–HELP command to view its detailed parameter descriptions:
