PerlDaemon is a minimal Unix daemon framework. It can be programmed in Perl to perform any task. It supports automatic daemonizing, logging and logrotate support, clean shutdown, and PID files (including a check on startup). It's easy to configure and easy to extend by customizing the daemonloop subroutine.
SwarmTv is a command line broad-catching program that downloads selected torrents/NZB's from an RSS or Twitter feed and puts them in a directory for your torrent program to download. The torrents to download are selected using filters that look at the name, size, and episode/season of the torrent. A mechanism is in place to prevent double downloads. Swarmtv can even send an email when a new episode is found.
Chef is a systems integration framework, built to bring the benefits of configuration management to your entire infrastructure. With Chef, you can manage your servers by writing code, not by running commands (via Cookbooks), integrate tightly with your applications, databases, LDAP directories, and more (via Libraries), and easily configure applications that require knowledge about your entire infrastructure ("What systems are running my application?" "What is the current master database server?").
skd is a small daemon which binds to a UDP, TCP, or Unix-domain socket, waits for connections and runs a specified program to handle them. It is ideal as a secure, efficient replacement for traditional inetd. It is also an easy-to-use tool for non-privileged users wanting to run their own network services. Datagram and stream sockets are available in both the Internet and Unix namespaces, each with the expected inetd behavior. In the Internet domain, IPv6 is supported in addition to IPv4. skd also supports connection limits, verbose logging of connections, dropping of privileges, forking into the background with a pidfile, and redirecting stderr to syslog or a file. Some of these facilities (such as forking into the background, privilege dropping, and logging) are also useful for standalone, non-network services and can be used without binding any socket.
Multi Threaded Daemon - enhanced is a class that implements a daemon that can spawn multiple parallel threads. It includes a sample app to monitor a "queue" directory on the filesystem, and spawns up to "N" child processes to parse individual files from it. It is an enhanced version of the original Multithreaded Daemon class written by Benoit Perroud. This version provides several robustness improvements, adds support for handling signals (SIGTERM, SIGHUP), and a unique PID file to avoid starting multiple instances.
sessiond allows a cluster of SSL/TLS servers to share their session caches in order to prevent each node of the cluster from negotiating a separate session. SSL/TLS session is basically a set of secret values (symmetric encryption keys, MAC secrets) shared between a client and a server. The use of asymmetric cryptography required to establish new sessions is the main performance bottleneck of the SSL/TLS protocol.
