Hi All - I'm trying to see if the below is possible using PHP.
is it possible for php to allow a user to check if a port is open/listening on a remote server/PC, from their local machine. I've seen scripts on the web that talk about opening cmd.exe - this won't work as not all of my users will be on windows. Also saw fsock.. but the remote server is not serving http page(s). Also saw telnet, but again, some of my users may not have that windows feature enabled.
1. user enters the server hostname/IP and a port
2. my php webapp will emulate checking if that hostname and port is open from the local user's computer.
