NSCA is the remote passive acceptance daemon used with many Nagios installs. It ships with a (C-language) executable called send_nsca for submitting checks. This is a mostly-clean re-implementation of send_nsca in pure-python. It supports 10 of the 26 crypto functions used by upstream NSCA, sending to multiple hosts with one invocation, and timeouts.
