How to check the port status of multiple IP Addresses from windows command prompt. I am looking for some Batch file or a Dos SCRIPT. Can anyone help on this?
You could use nmap http://nmap.org to script something to check and list whats open on a given host or set of hosts
TiZon is right though, wed need to know more about what youre wanting to do before we could give a more concise answer.... Are you checking more than one host, the same ones over and over, more than one port, etc?
Just a wild assumption... If you want a robust monitoring and alerting system you could look at nagios www.nagios.org its free and does a great job monitoring and alerting for things like open / closed ports
I second nmap, but you can check for open connections with telnet
