firewalling is great... but it lacks some flexibility port knocking brings you easily.
It's not THE ultimate securing solution. It's just another layer preventing DIRECT access to specified port(s). After knocking you still might want to use good security practices to enable access to your services (i.e. disable root login w/ SSH, force certificate usage as much as possible, VPN your connections, etc.)
Welcome to the KnockIt! project.
There is no rocket science here. Only one window and three buttons : check if server:port is available, send the port knocking opening sequence to your server and send the port knocking closing sequence to your server.
No UDP or ICMP provided yet. Proxy settings to come soon.

V1.1
UDP knocking added.
V1.2
Changed the fixed text boxes to lists in order to enable "unlimited" arguments.
Thinking about doing the same for different services configuration or different servers (might take a while... not a full timer)
