The inetd daemon listens for connections on certain Internet sockets (info in /etc/nf) and handles those requests. It reduces system load by invoking other daemons. The /usr/sbin/inetd daemon provides Internet service management for a network. Thus, when the RPC servers start they can register with portmap. It is started from /etc/rc.tcpip before inetd and the RPC servers (e.g. Portmap daemon listens on port number 111. When a client sends an RPC to the server, the portmap daemon answers to the client which port to send the call to. The portmap daemon knows the location of every registered port on the host and which programs are available on each of these ports. When an RPC server starts up, it registers with the portmap daemon. The portmap daemon converts remote procedure call (RPC) program numbers into Internet port numbers. When inetd started, it reads its configuration from this fileĬontains the name of the services that inetd listens for requests and starts as needed Starts TCP/IP daemons (sendmail, portmap, inetd, etc., and other daemons: syslogd, lpd. Rcnfs:23456789:wait:/etc/rc.nfs > /dev/console 2>&1 # Start NFS Daemons Rctcpip:23456789:wait:/etc/rc.tcpip > /dev/console 2>&1 # Start TCP/IP daemons Then during initialization the file /etc/inittab is called. Sets hostname, default gateway and static routes.(it is called by cfgmgr)
