LINUX LIST PROCESSES LISTENING ON PORTS HOW TO

How to obtain additional information about the Netstat.exe utility You should be able to easily find the process ID and match it to the program that is listed in Task Manager. Select the column header that is labeled 'PID' to sort the process by PIDs.If you don't have a PID column, select View > Select Columns, and then select to select the PID (Process Identifier) check box.Select Ctrl+ Shift+ Esc to open Task Manager.To match the process ID to a program, follow these steps: Because a program already uses this specific port, another program is prevented from using that same port. With this feature, you can find the specific port that a program currently uses. If you use Task Manager, you can match the process ID that is listed to a process name (program). For example, the netstat -ano command can produce the following output: Proto Local Address Foreign Address State PID Linux Find Out Which Process Is Listening Upon a Port You can the following programs to find out about port numbers and its associated process: netstat command or ss command a command-line tool that displays network connections, routing tables, and a number of network interface statistics.

will show you the PID and process name as the last column, checkout 'man netstat' if you want to change the options. This information can be used to determine which process (program) listens on a particular port. With lsof -iTCP -sTCP:LISTEN you get a list of all TCP ports in state LISTEN and their associated processes (command and pid are in the first two columns). The Netstat.exe utility has a new switch, the -o switch, that can display the process identifier (ID) that is associated with each connection. This step-by-step article discusses how to determine which program uses or blocks specific Transmission Control Protocol (TCP) ports.įor a Microsoft Windows XP version of this article, see 281336.Īpplies to: Windows Server 2003 Original KB number: 323352 Summary
