net.app

What's this?

Given you know an open TCP port at a host and want to know which application is waiting for connections.
In net mode, we try to find it out without knowing anything. It takes longer than head, a mode based on rough knowledge of the protocol.
Most information we gather here can be retrieved via telnet or nmap, but needs the outbound port on your client to be open.

Reason for building this service

I built this service because I occasionally appear to find myself in corporate networks not allowing me to probe any port I need.

Legal notice

In some countries, a scan like this can be restricted by local laws or require permission of representatives for affected systems. Clez.net just provides this tool and does not check if you actually are allowed to use it. So it's up to you ;)
