Description

Knock 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 knockd server.

Compatible with all RHEL-based distributions, including CentOS, AlmaLinux, Oracle Linux, Rocky Linux, etc.
