How to kill a process on a port on ubuntu

Question

I am trying to kill a process in the command line for a specific port in ubuntu.

If I run this command I get the port:

sudo lsof -t -i:9001


        

Answer 1

You may also use fuser to do that (sends SIGKILL by default): sudo fuser -k 9001/tcp

Answer 2

Use killport command :

sh killport 9001 

To Download shell ,you can use wget :

wget https://cdn.rawgit.com/abdennour/miscs.sh/e0aac343/killport

Answer 3

Use the command

 netstat -plten |grep java

used grep java as tomcat uses java as their processes.

It will show the list of processes with port number and process id

tcp6       0      0 :::8080                 :::*                    LISTEN      
1000       30070621    16085/java

the number before /java is a process id. Now use kill command to kill the process

kill -9 16085

-9 implies the process will be killed forcefully.

Answer 4

you can work this using node

npm install freethenport -g

then

node freethenport 9001

Answer 5

Displays active TCP connections, ports on which the computer is listening.

netstat -tupln

It will list you all the connection along pid. Find and copy the pid and run the following command. Make sure you replace the with actual id in the following command.

kill -9 <copied pid>

-9 use to forcefully kill the connection.

Answer 6

To kill a process running on Port number 9001

sudo kill -9 $(sudo lsof -t -i:9001)


lsof   - list of files(Also used for to list related processes)

-t     - show only process ID

-i     - show only internet connections related process

:9001  - show only processes in this port number

kill   - command to kill the process

-9     - forcefully

sudo   - command to ask admin privilege(user id and password).
