An internet protocol service (ipsv) daemon waits for incoming connections
|
|
|
|
|
on a local socket; for new connections, it conditionally runs an arbitrary
|
|
|
|
|
program with standard input reading from the socket, and standard output
|
|
|
|
|
writing to the socket (if connected), to handle the connection. Standard
|
|
|
|
|
error is used for logging.
|
|
|
|
|
|
|
|
|
|
ipsv 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.
|
|
|
|
|
|
|
|
|
|
Normally the ipsv daemons are run by a supervisor process, such as runsv
|
|
|
|
|
from the runit package, or supervise from the daemontools package.
|
|
|
|
|
|
|
|
|
|
ipsvd can be used to run services normally run by inetd, xinetd, or tcpserver.
