kill/remove a process running on particular port in Linux

​Use the command

option 1:

  netstat -tulpn | grep 1100

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

tcp        0      0 0.0.0.0:1100                0.0.0.0:*                   LISTEN      22746/Rserve.dbg

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

kill -9 22746

-9 implies the process will be killed forcefully.

option 2:

lsof -i:1100;kill -9 22746

oneshot: kill -9 $(lsof -t -i:1100)

option 3:


# fuser 1100/tcp
# fuser -k 1100/tcp (kill)
