This article explains how to verify listening ports and port usage in a Linux® system. Using the lsof command The lsof (List Open Files) command produces a list of files that are currently open along with the processes that opened them. When combined
For example, if you are running an Apache or Ngnix based web server, the port in use should be 80 or 443. Checking the ports will confirm that. Similarly, you can check which port is being used by SMTP or SSH or some other services. Knowing which ports are in use can be helpful wh...
This article explains how to find out the ports in use and which services are listening on which ports using the netstat, ss and lsof commands. The instructions are applicable for all Linux and Unix-based operating systems like macOS.

port:是端口,比如80 如果telnet连接不存在的端口,那会如下图所示。 如果telnet 连接存在端口会出现如下图所示的内容,下图中以80端口为例。 1、Linux关闭telnet服务 操作方法:vi /etc/xinetd.d/telnet,将disable=no改成disable=yes; 2、将telnet设置为禁止开机自启动,操作方法:chkconfig telnet off; ...
When viewing the open/listening ports and connections, its often useful to know the process name/pid which has opened that port or connection. For example the Apache httpd server opens port 80. So if you want to check whether any http server is running or not, or which http server is ...
