ipsvd is a set of Internet protocol service daemons for TCP/IP (optionally SSLv3) and UDP/IP. A daemon waits for incoming connections on a socket; for new connections, it conditionally runs an arbitrary program to handle the connection. The daemons can be told to read and follow pre-defined instructions on how to handle incoming connections; based on the client's IP address or hostname, they can run different programs, set a different environment, deny a connection, or set a per host concurrency limit. ipsvd can be used to run services usually run by inetd or tcpserver. Normally the daemons are run by a supervisor process, such as runsv from the runit package.
