It is often a pain to write a server program that supports graceful restarts, with no resource leaks. The Perl 5 module Server::Starter, solves the problem by splitting the task into two. One is start_server, a script provided as a part of the module, which works as a superdaemon that binds to one or more TCP ports, and repeatedly spawns the server program that actually handles the incomming commenctions. The spawned server programs under Server::Starter call accept(2) and handle the requests.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
