Check for open ports on computer
1. Linux Create a file on console steps below --------------------------- $ nano portscan.sh -------------------------------- #!/bin/bash nmap -sS -O ip.address.off.the.server Save the file $chmod 777 portscan.sh ------------------------------------------------------------------ Basically you can just run the command much simpler $ nmap -sS -O ip.address.off.the.server It will output PORT STATE SERVICE 22/tcp open ssh 80/tcp open http 443/tcp open https 1241/tcp open nessus ----------------------------------------------------------------- --- the scanning is for open ports since all ports are closed in linux --- in windows create a batch file c:\>copy con portscan.bat paste inside: netstat -a | find "LISTENING" save the file -- NOTE THIS IS if you are inside the machine ---
