Internet protocol service daemons

 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.
