Description
This is a port-knocking server/client. Port-knocking is a method where a server can sniff one of its interfaces for a special "knock" sequence of port-hits. When detected, it will run a specified event bound to that port knock sequence. These port-hits need not be on open ports, since we use libpcap to sniff the raw interface traffic. This package contains the knock client.
Built for AlmaLinux, Rocky Linux, Oracle Linux and RHEL.
