Finding Application / Process Running On Particular Port In Linux Systems

Today, I'm going to show you how to find application / process running on particular port in Linux Systems.

We can use lsof command to find the process running on particular port. The syntax of lsof command to find the application running on particular port looks like following..

lsof -i :port

Summary of above code...
lsof command is used to list open files.. and the argument -i is used to list files whose ip address / port matched to specified ip address / port.

Note: If you ignore ip address / port after -i then the above command will lists processes for all ip addresses...

For example to find the process / application listening on port 80, run the following code..

lsof -i :80

The output will looks like following..

shivaraj@shivaraj-A14RM0E:~$ lsof -i:80 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME plugin_ho 3981 shivaraj 20u IPv4 420822 0t0 TCP 192.168.0.117:33104->45.55.41.223:http (CLOSE_WAIT) shivaraj@shivaraj-A14RM0E:~$

If you omit port value... lsof -i the output will looks like following one..

shivaraj@shivaraj-A14RM0E:~$ lsof -i COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME plugin_ho 3981 shivaraj 20u IPv4 420822 0t0 TCP 192.168.0.117:33104->45.55.41.223:http (CLOSE_WAIT) node 4165 shivaraj 12u IPv4 509873 0t0 TCP *:http-alt (LISTEN) firefox 4178 shivaraj 114u IPv4 7216095 0t0 TCP 192.168.0.117:42436->server-54-230-190-100.maa3.r.cloudfront.net:https (ESTABLISHED) shivaraj@shivaraj-A14RM0E:~$

By specifying -t for lsof command we can get pid of process listening on particular port... Look at the below command signature..

lsof -t -i :port

If you want to find out pid of process listening on port 80, run the following code..

lsof -t -i :80

The above commands output will looks like..

shivaraj@shivaraj-A14RM0E:~$ lsof -t -i :80 3981 shivaraj@shivaraj-A14RM0E:~$

Record Your DESKTOP SCREEN
With VLC Media Player

VLC media player (commonly known as VLC) is a portable, free and open-source, cross-platform media player and streaming media server written by the VideoLAN project. VLC is available for desktop operating systems and mobile platforms, such as Windows 10 Mobile, Windows Phone, Android, iPad, iPhone, and iPod Touch. VLC is also available on App stores such as Apple's App Store and Microsoft Windows Windows Store.

VLC media player supports many audio and video compression methods and file formats, including DVD-Video, video CD and streaming protocols. It is able to stream media over computer networks and to transcode multimedia files.

The default distribution of VLC includes a large number of free decoding and encoding libraries, avoiding the need for finding/calibrating proprietary plugins. The libavcodec library from the FFmpeg project provides many of VLC's codecs, but the player mainly uses its own muxers, and demuxers. It also has its own protocol implementations. It also gained distinction as the first player to support playback of encrypted DVDs on Linux and OS X by using the libdvdcss DVD decryption library.
