check_host: Plugin which will send an arbitrary packet (icmp echo, tcp SYN) to a host and returns OK if _any_ response (including “ICMP prohibited” or TCP RST) is received from the host IP to check host presence in cases where ICMP is filtered by a firewall.
contrib plugins: move each plugin to its own subdirectory to ease selective bulding
Wrapper Script that allows easy connection between send_nsca and a Nagios plugin: send_nsca expects the return value of the plugin on the command line, interface code is necessary.
