A port knocking implementation. | |
Provides a daemon and a user application. Port knocking can be | |
used to run an arbitrary application, once the daemon detects | |
a predefined sequence of incoming TCP/UDP packets on a network | |
interface. This can be used, e.g. to open up ports in a | |
firewall. | |
