Linux free / kill TCP port - Closed -


i have tcp port listening @ 3299, when use

netstat -tulpn | grep :3299

it shows 

tcp   0    0 0.0.0.0:3299        0.0.0.0:*                   listen      -

i tried 

fuser -k 3299/tcp

but says

-bash: fuser: command not found

i not running below command root user, not showing me process id of process.

tcp   0    0 0.0.0.0:3299        0.0.0.0:*                   listen      -

once logged in using root user, see process id, 

tcp        0      0 0.0.0.0:3299 0.0.0.0:*             listen      8047/java

then killed using kill -f 8047
