How Linux looks at which process the port is consuming

This article describes how Linux can see how a port is consumed by which process:

1. Lsof-i: Port number

2. Netstat-tunlp|grep Port number

can see which process is consuming the specified port

"Step One" lsof-i

The lsof-i is used to display conditions that match the condition, and lsof (list open files) is a tool that lists open files for the current system. To execute the lsof-i command with the root user

"Step Two" Lsof-i: Port number

Lsof-i: Port number used to view the occupancy of a port, for example, to view ports 22nd usage, lsof-i:22

"Step three" NETSTAT-TUNLP

NETSTAT-TUNLP is used to display TCP,UDP ports and processes, and other related situations

"Step Four" Netstat-tunlp|grep port number

Netstat-tunlp|grep port number for viewing the process of a specified port number, such as viewing Port 22, Netstat-tunlp|grep 22
