NAME

inetd − internet services daemon

SYNOPSIS

/etc/inetd [ −d ]

DESCRIPTION

Inetd is the internet super-server which invokes all internet server processes as needed.  Connection-oriented services are invoked each time a connection is made, by creating a process.  This process is passed the connection as file descriptor 0 and an argument of the form “sourcehost.sourceport” where sourcehost is hex and sourceport is decimal. 

Datagram oriented services are invoked when a datagram arrives; a process is created and passed the connection as file descriptor 0.  Inetd will look at the socket where datagrams arrive again only after this process completes.  The paradigms for such proceses are either to read off the incoming datagram and then fork and exit, or to process the arriving datagram and then time out. 

Services supported by inetd are ftp ftpd(8C), telnetd(8C), rshd(8C), rlogind(8C) and rexecd(8C) which are conection based and tftpd(8C) and comsat(8C) which are datagram based.

OPTIONS

−d Specifies that debugging traces are to be turned on for connection-oriented (TCP) services. 

SEE ALSO

comsat(8C), ftpd(8C), rexecd(8C), rlogind(8C), rshd(8C), telnetd(8C), tftpd(8C)

BUGS

The services supported by the program are hard-wired. 

There is no provision for selectively invoking TCP debugging packet tracing per-service.
