  inetd.conf

  NAME

    inetd.conf - inetd configuration file

  DESCRIPTION

    The inetd.conf file is the configuration file for the inetd(1) daemon. The
    file contains the list of Internet-related services that inetd(1) can
    invoke when it receives a request from an Internet client.

    Each line of the inetd.conf file has configuration information for one
    service. The format is:

    [camp-]service_name   socket_type   protocol   {wait|no wait}   user
    {daemon|internal}   arguments

    Pound signs (#) are used to mark comments.

    Below is a description of each field in the inetd configuration file.
    [camp-]
        Disables the indicated service, but blocks access to the default port
        used by the service. Use this to prevent a trojan horse program from
        using the port.

    service_name
        The name of a service listed in the %windir%/system32/drivers/etc/
        Services file. Remote procedure call (RPC) service names are followed
        by a slash and the version number or range of version numbers.
        Internal service names must be the first entry from the %windir%/
        system32/drivers/etc/Services file.

    socket_type
        One of the following: stream, a stream socket; dgram, a datagram
        socket; raw, a raw socket; rdm, a reliably delivered message socket;
        or seqpacket, a sequenced packet socket.

    protocol
        The name of a protocol listed in the %windir%/system32/drivers/etc/
        protocol file. For RPC services, use RPC followed by slash (/) and the
        name of the protocol; for example, rpc/udp.
    {wait|no wait}
        Multi-threaded servers, datagram servers that connect to peers and
        free a socket for inetd to receive more packets on the socket, should
        use nowait. Single-threaded servers, datagram servers that do not
        release the socket until a time-out occurs, must be set to wait.
        The tftpd(1) daemon, a datagram server that establishes separate
        pseudo connections, must be set to wait. Although it appears to need a
        nowait entry, its forking behavior can lead to a race condition unless
        it is set to wait.

    user
        The user under which the server program will run. This allows servers
        to run with less access than the root account.
    {daemon|internal}
        The path name to the server program that inetd starts when asked to
        perform a requested service. Contains the value internal if inetd
        provides the service internally.

    arguments
        The argument(or arguments) that should be passed to the server
        program. You must include the entire command line (the server program
        name is passed as argv[0]). If the server program is internal, you can
        leave this blank.

  EXAMPLES

    The following line is an example from the Interix inetd.conf file.

    ftp   stream   tcp   nowait   NULL   /usr/sbin/in.ftpd   in.ftpd -l

    ftp
        Service name. Listed in %windir%/system32/drivers/etc/Services.

    stream
        Socket type.

    tcp
        Protocol. Listed in %windir%/system32/drivers/etc/protocol.

    nowait
        Set to nowait because ftp is a multi-threaded datagram server

    NULL
        The user associated with this server program.

    /usr/sbin/in.ftpd
        The path and file name of the daemon or server program.

    in.ftpd -l
        The server program arguments. The argument in.ftpd is argv[0] and -
        l is argv[1].

  FILES

    /etc/inetd.conf
        The inetd(1) configuration file.

    %windir%/system32/drivers/etc/Services
        Provides service name-to-port identification resolution for Windows
        Sockets applications. The list of valid services that can be used by
        inetd.

    %windir%/system32/drivers/etc/protocol
        Provides protocol name-to-protocol identification resolution for
        Windows Sockets applications. The list of valid protocols that can be
        used by inetd.

  NOTES

    To prevent tampering, if the permissions protecting inetd.conf file allow
    the file to be written by anyone other than the file's owner and group,
    the file is ignored and an error is logged using syslogd.
