check_dnssec is a set of Nagios plugins to monitor DNSSEC services/zones. check_dnssec is based on ldns, a low-level DNS(SEC) library. check_dnssec_expiration checks if a domain is signed and the signature is not exited or expiring soon. check_dnssec_trace checks if a domain can trust traces from a domain with a trust-anchor. check_dnssec_trust_anchor checks if all trust anchors in a file are valid.
MPIBurn is an MPI unicast benchmark. Modern inter-connect hardware handles broadcast messages with a different algorithm than that used for unicast messages. Just benchmarking broadcasts or N to N+1 messaging may not detect inter-connect malfunctions, so MPIBurn benchmarks any possible unicast connection while assuring to involve as many connections in parallel as possible. After each round, the peers are scrambled to ensure that the next round has completely different connection groups.
