How to detect port 23 status

[ChrisW67]

Blocked inbound or outbound? Try to connect to the machine (or a remote machine if you are supposedly blocking outbound) if it succeeds then the firewall is a failure, if it fails the the firewall may still be a failure because there are many, many ways for a connection to fail.

If you want a Windows API call to find out what the Windows firewall settings are then it is best you ask Microsoft

Thanks Chris,

My concern is to validate port(23) and not the Firewall.The user should be intimated with message "Telnet port blocked !!!" if blocked inbound/outband by firewall.


Thanks,
