  • If that's not possible using the socket feature newer versions of bash support
  • And only if nothing of these is useable resort to telnet

Example of how easy it's with netcat/nc:
Code:
for port in {1000..1050}; do nc -z -w 3 1.2.3.4 $port && echo "Port $port open" || echo "Port $port closed"; done


My server is a production server and I can't installing anything, for I am not the admin and it requires approvals.

Would someone help me with the correct netstat script to figure which ports are connecting and which are not.
