sysadmin This program is designed to accept passive service check results from clients that use the send_nsca utility (which is included in this package) and pass them along to the Nagios process by using the external command interface. The program can either be run as a standalone daemon or as a service under inetd. If you have libmcrypt installed on your systems, you can choose from multiple crypto algorithms (DES, 3DES, CAST, xTEA, Twofish, LOKI97, RJINDAEL, SERPENT, GOST, SAFER/SAFER+, etc.) for encrypting the traffic between the client and the server. Encryption is important in this addon, as it prevents unauthorized users from sending bogus check results to Nagios. Read the included SECURITY document for more information. This package provides the send_nsca utility running on the client. Build support for crypted communication with nsca, through dev-libs/mcrypt. It's recommended not to disable this flag unless all the communication will be handled in an absolutely safe environment. Only build and install the send_nsca command and not the daemon. This allows a very minimal install with no overhead when setting up a node. nagios
