NAME

       identd - TCP/IP IDENT protocol server

SYNOPSIS

       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.

   Arguments
       The	 flag,	which  is the default 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.

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

       The	 flag can be used to make the daemon run in standalone mode without the assistance from This mode is the least preferred mode, and
		 not supported by HP, since a bug or any other fatal condition in the server will make it terminate and it will then  have  to	be
		 restarted manually.

       The	 option  is used to specify the timeout limit. This is the number of seconds a server started with the flag will wait for new con-
		 nections before terminating. The server is automatically restarted by whenever a new connection is requested  if  it  has  termi-
		 nated. A suitable value for this is 120 (2 minutes), if used. It defaults to no timeout.  That is, it will wait forever, or until
		 a fatal condition occurs in the server.

       The	 option is used to 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.

       The	 option  is  used  to 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.

       The	 option is used to specify an alternative port number to bind to if using the mode of operation. It can be specified by name or by
		 number. Defaults to the IDENT port(113).

       The	 option  is  used to 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 it is which normally represents  all	the  local
		 addresses.

       The	 flag makes display the version number and the exit.

       The	 flag tells to use the System logging daemon for logging purposes.

       The	 flag tells to not reveal the operating system type it is run on and to instead always return "OTHER".

       The	 flag tells to always return instead of the or errors.

       The	 flags	tells  to  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 upper case characters.

       The	 flags tells to always return user numbers instead of user names if you wish to keep the user names a secret.

       The	 flag makes check for a file in each home directory for a user which the daemon is about to return the user name for. It that file
		 exists then the daemon will give the error instead of the normal response.

       The	 flag  makes  use a mode of operation that will allow 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.

       The	 flag  enables	some debugging code that normally should be enabled since that breaks the protocol and may reveal information that
		 should not be available to outsiders.

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  ser-
       vices(4)) when using the or modes of operation or started manually by using the mode of operation.

WARNINGS

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

EXAMPLES

       Since the server is located in you can put either:

       or:

       into the file.

       To start it using the unsupported mode of operation, you can put a line like this into 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
