NAME
       identd - TCP/IP IDENT protocol server

SYNOPSIS
       seconds] seconds] uid] gid] port] address] charset]

DESCRIPTION
       is  a  server  which implements the TCP/IP proposed standard IDENT user
       identification protocol as specified in the RFC 1413 document.

       operates by looking up specific TCP/IP connections  and	returning  the
       user name of the process owning the connection.

   Options
       The protocol server recognizes the following options:

       Specify the local address to bind the socket to if using
		 the  mode  of	operation.   Can  only	be specified by the IP
		 address and not by the domain name.   The  default  value  in
		 IPv4  is  and	in  IPv6  is which normally represents all the
		 local addresses.

       Run in standalone mode without
		 assistance from This mode is the least preferred mode and not
		 supported  by	HP.  A bug or any other fatal condition in the
		 server will make the server terminate, and it will then  have
		 to be restarted manually.

       Add the optional (according to the IDENT protocol) character set
		 designator to the reply generated.  charset should be a valid
		 character set as described in the MIME RFC in uppercase char‐
		 acters.

       Enable some debugging code that normally should
		 be enabled since it breaks the protocol and may reveal infor‐
		 mation that should not be available to outsiders.

       Always return
		 instead of the or errors.

       Specify a group id number which the
		 server should switch to after binding itself  to  the	TCP/IP
		 port if using the mode of operation.

       Default mode.
		 This  mode  should be used when starting the daemon from with
		 the "nowait" option in the file.  Use of this mode will  make
		 start one daemon for each connection request.

       Use the system logging daemon
		 for logging purposes.

       Use a mode of operation that allows multiple requests to be
		 processed  per	 session.   Each  request is specified one per
		 line and the responses will be returned one  per  line.   The
		 connection  will  not	be  closed  until  the connecting part
		 closes its end of the line.

       Always return user numbers instead of user names in order to
		 keep the user names a secret.

       Check for a file
		 in each home directory for a user which the daemon  is	 about
		 to  return  the  user name for.  If that file exists then the
		 daemon will give the error instead of the normal response.

       Do not reveal the operating system type it is run on and always return
		 instead.

       Specify an alternative port number to bind to if using
		 the mode of operation.	 The port can be specified by name  or
		 by number.  It defaults to the IDENT port (113).

       Used to specify the timeout limit.
		 This  is the number of seconds a server started with the flag
		 will wait for new connections before terminating.  The server
		 is  automatically  restarted  by whenever a new connection is
		 requested if it has terminated.  A suitable value for seconds
		 is  120  (two	minutes), if used.  It defaults to no timeout.
		 That is, it will wait forever, or  until  a  fatal  condition
		 occurs in the server.

       Specifies the maximum number of seconds a server will wait for the
		 client's  input before closing the connection on timeout.  By
		 default, the timeout limit is 0 (zero); that is,  the	server
		 waits	for  an	 indefinite  amount  of	 time.	This option is
		 ignored for invalid timeout intervals.

       Specify a user id number which the
		 server should switch to after binding itself  to  the	TCP/IP
		 port if using the mode of operation.

       Display the version number and exit.

       Use this option when starting the daemon from
		 with  the  "wait" option in the file.	The daemon will either
		 run forever or until a timeout, as  specified	by  the	 flag,
		 occurs.

INSTALLATION
       is  invoked  either by the internet server (see inetd(1M)) for requests
       to connect to the IDENT port as indicated by the file (see services(4))
       when  using  the or modes of operation or started manually by using the
       mode of operation.

WARNINGS
       The and options are currently not supported on HP-UX.

EXAMPLES
       Assume the server is located in Add either of the following  two	 lines
       into the file:

       or:

       To  start  using	 the  unsupported mode of operation, add the following
       line to the file under the start section:

       This will cause to be started as daemon whenever is running.   It  will
       run in the background as user 2, group 2 (user group
