Binary package “ipsvd” in ubuntu hardy
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.
