Linux: Force Close A Socket / Port On Server In a TIME_WAIT State

You can use the “ss” or “lsof” command to identify the process that is using the socket/port in a TIME_WAIT state and then use the “kill” command to force close it.

Example using ss:

$ ss -tna | grep <port_number>

The output will show the process using the socket/port.

$ kill -9 <process_id>

Example using lsof:

$ lsof -i:<port_number>

The output will show the process using the socket/port.

$ kill -9 <process_id>
