Hi

I need to know whether a connection opened to my server was done using 'telnet'.

How do I do that ? should I need to use winsock and/or other objects ?

Thanks,


Liron Golan

You can try timing the input. There is nothing Telnet sends that would identify it.

telnet is typically on port 21, i think. but not always. it depends on your server.

are you trying to prevent people from telneting to your server? or simply log that connection or what?

there are many software packages out there that can do either or both of these. check out http://www.webtrends.com
