Go: Windows netstat command to view port usage

Netstat-ano

Find display Netstat-ano|findstr "Find content, port number IP address, etc."

In the Windows System netstat command can know the view port, process occupation, then under the netstat command how to do it! Now let's take a look!

Target: In a Windows environment, use the netstat command to see if a port number is occupied and which process is occupied.

Action: The operation is divided into two steps: (1) Check that the port is occupied by that PID; method one: Targeted view port, using command

Netstat–ano|findstr "< port number >", the last column is PID. The port number in the figure is 1068, and the corresponding PID is 3840.

(a) Figure

Method Two: View all, and then find the corresponding port and PID.

(b) Figure

The 5 columns in the first picture are the 5 columns corresponding to the above (a) figure.

(2) View the process name of the PID.

Method One: Always use the command to find, Tasklist|findstr ""

(c) Figure

As can be seen from the (c) figure, the PID 3840 corresponds to the process name Msnmsgr.exe.

Method Two: View with Task Manager.

Bring up the Task Manager and select columns, such as the D chart.

(d) Figure

View the PID corresponding process name. As shown in (e) Msnmsgr.exe

Appendix: On the command line, enter netstat/? You can view information about the netstat.

-e Displays Ethernet statistics. This option can be used with the-s

Combination of options.

-N Displays the address and port number in digital form.

-O Displays the owning process ID associated with each connection.

-p proto shows the connection proto the specified protocol; proto can be

One of the following protocols: TCP, UDP, TCPv6, or UDPV6.

If used with the-s option to display per-protocol statistics, Proto can be one of the following protocols:

IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, or UDPV6.

-r Displays the routing table.

-S displays statistical information by protocol. By default, the display IP,

IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, and UDPV6 statistics;

The-p option specifies a subset of the default conditions.

-T displays the current connection offload status.

-V is used with the-B option to display the containing
