How to listen for multiple tcp connection using nc [closed]

4 using nc it is not possible to open parallel connections to same port, however you can trick nc to open multiple connections to same port. To understand this, lets say you start listening on 4444 port using $ nc -l -p 4444 -v. Now, if you check output of $ netstat -anp | grep 4444 you will get its state as LISTEN and in here its pid is 3410.
