I m working on a Yocto Linux system that has a limited set of available Linux tools  I wanted to kill the process that was using a particular port  1883    First  to see what ports we are listening to I used the following command   root root    netstat -lt Active Internet connections  only servers  Proto Recv-Q Send-Q Local Address           Foreign Address         State        tcp        0      0 0 0 0 0 hostmon         0 0 0 0                 LISTEN       tcp        0      0 localhost localdomain domain 0 0 0 0                 LISTEN       tcp        0      0 0 0 0 0 9080            0 0 0 0                 LISTEN       tcp        0      0 0 0 0 0 1883            0 0 0 0                 LISTEN       tcp        0      0    hostmon                                      LISTEN       tcp        0      0 localhost domain                                LISTEN       tcp        0      0    ssh                                          LISTEN       tcp        0      0    1883                                         LISTEN         Next  I found the name of the process using port 1883 in the following way   root root    fuser 1883 tcp 290  root root    ps   grep 290   290 mosquitt 25508 S     usr sbin mosquitto -c  etc mosquitto mosquitto conf 12141 root      8444 S    grep 290   As we can see above  it s the program  usr sbin mosquitto that s using port 1883   Lastly  I killed the process   root root    systemctl stop mosquitto   I used systemctl becuase in this case it was a systemd service
