NOTE: See documentation for listen() socket call. TCP sockets in listening state are not shown - this is a limitation of NETSTAT. For additional information, please see the following article in the Microsoft Knowledge Base: 134404 NETSTAT.EXE Does Not Show TCP Listen Sockets FIN_WAIT_1 Indicates active close.

The linux version of netstat uses a notation of <IP>:<port> where the IP address is displayed bare*. So :::111 means an IP of :: and a port of 111. :: is an IPv6 address in condensed form using the rule that a run of zeros can be replaced with ::.

Running netstat -n to show the IP, I realized it was one of my own GCP servers - which made me wonder even more what was going on, thinking perhaps reverse DNS or even one of my DNS servers or something was configured incorrectly or something. Reverse DNS looked fine, although it should've clicked once I saw the reverse DNS.

2017年4月8日 · On Windows Server 2008, Vista, NT, 2000 and XP TCPView also reports the name of the process that owns the endpoint. TCPView provides a more informative and conveniently presented subset of the Netstat program that ships with Windows. The TCPView download includes Tcpvcon, a command-line version with the same functionality.

netstat -o includes some timer information in the output but I haven't found an explanation of the output in the Timer column anywhere. Can anybody explain this or point to an explanation? This ist what the ouptput of netstat -o looks like (on Ubuntu 8.04).

2017年7月28日 · when i run command netstat -ano I have: PS Y:\\PowerShell&gt; netstat -ano Active Connections Proto Local Address Foreign Address State PID TCP 0.0.0.0:80 ...

Here is an example for windows using FOR to parse netstat output then DO tasklist with /fi filter on pid to show process name. The last find is to remove tasklist headers. FOR /F "usebackq tokens=5 delims= " %i IN (`netstat -ano ^|find "443"`) DO @tasklist /fi "pid eq %i" | find "%i" prints records output like

2008年11月3日 · But on production systems you may not be allowed to install additional software, so I think you may want to try out netstat.exe, which is typically located at C:\WINNT\system32\netstat.exe . A help page is available with . netstat -? Examples are: netstat -a Lists all local TCP connections and listening ports together with remote TCP endpoint.

2012年8月18日 · For port 80, the command would be : netstat -an | find "80" For port n, the command would be : netstat -an | find "n" Here, netstat is the instruction to your machine -a : Displays all connections and listening ports -n : Displays all address and instructions in numerical format (This is required because output from -a can contain machine names)

To check if the port is free I checked it using netstat but it shows that port number 8000 is free. It has happened with me a lot of times. Every time I then wait for a few more secs and then it starts working again. I am using c language. So what is he reason for this behavior by my OS. After a few more secs I run the code and then it works.
