The following syntax will also list all interfaces. To display Route Table, you can use the below syntax. The above command filters all the errors from statistics of all protocols. netstat -s | findstr Errors C:\Windows\system32> netstat -s | findstr Errors To find out any errors quickly you can use syntax. You will see the statistics of all protocols as shown below. It will list out statistics from IPv4, IPv6, ICMPv4, ICMPv6, TCP, UDP, etc. Useful when you have to find out for any received header error, received address error, discarded packet, etc. C:\Windows\system32> netstat -o | findstr 50664 You can see the following info if you use the above command. And its the process identifier.Ī very handy when you have to find out which PID is using the particular port number. Proto Local Address Foreign Address State PID Let’s run the command and see how we get the result. The above command displays all the connections with PID. We can see the PID of every socket connection using the following command. And every process has an ID, and its called PID. TCP 192.168.43.15:52590 server-13-33-179-97:https TIME_WAIT Show PID used by port numberĮvery connection is a process internally. Netstat | findstr TIME_WAIT C:\Windows\system32> netstat | findstr TIME_WAIT TCP 192.168.43.15:52584 ec2-34-227-121-63:https CLOSE_WAITįinally, use the TIME_WAIT flag to get information about all the connections that are in TIME_WAIT state. Similarly, run the following command to see all the connections that are in CLOSE_WAIT state. netstat | findstr LISTENING C:\Windows\system32> netstat | findstr LISTENING TCP 192.168.43.15:139 DESKTOP-A0PM5GD:0 LISTENING You will get the information about connections that are in the listening state as follows. To see the connections that are in LISTENING state change ESTABLISHED keyword in the previous command to LISTENING. Note: to view LISTEN, CLOSE_WAIT, TIME_WAIT you can just use as follows. Netstat | findstr ESTABLISHED C:\Windows\system32> netstat | findstr ESTABLISHED You can use below syntax to view all established connections from/to your Windows server. We have seen the state in the connection information. We can filter the connections in different ways. State – defines the state of the socket (LISTENING, ESTABLISHED, CLOSE_WAIT, TIME_WAIT).Foreign Address – displays remote computer that your computer is connected to, the remote end of the socket.Local Address – displays your computer IP address and port, local end of the socket.Proto – defined the protocol type (TCP, UDP, etc.,) of the socket.You will see a header with Proto, Local Address, Foreign Address, and State. Proto Local Address Foreign Address State You will see all the active connections from different states as shown below. To start with netstat, let’s see the command that displays all connections. Let’s get it started… Show all connections
