DESCRIPTION
       update-inetd can be used to add, remove, enable or disable  entries  in
       the /etc/inetd.conf file (you can specify a different file by using the
       --file option).	After  the  /etc/inetd.conf  file  has	been  changed,
       update-inetd  will  send  a  SIGHUP signal to the inetd process to make
       sure that inetd will use the new /etc/inetd.conf file. For Perl scripts
       you  can also use the Perl module DebianNet.pm . See DebianNet(3pm) for
       further information.  update-inetd can also be used to add entries that
       are commented out by default. They will be treated like normal entries.
       That also means that if you already have an entry that is commented out
       you  cant  add  an entry for the same service without removing the old
       one first.

       update-inetd treats entries that are commented  out  by	a  single  #
       character  as  entries that have been commented out by a user. It wont
       change such entries.



OPTIONS
       --version
	      Print version information on standard output and	exit  success
	      fully.


       --help Print  a usage message on standard output and exit successfully.


       --verbose
	      Explain what is being done.


       --debug
	      Enables debugging mode.


       --file FILENAME
	      Use FILENAME instead of /etc/inetd.conf .


       --group GROUPNAME
	      Specify that the new entry should be placed in  group  GROUPNAME
	      (e.g.  MAIL").  If  the  group does not exist the entry will be
	      placed at the end of the file.  The default group is OTHER".


       --comment-chars CHARACTERS
	      update-inetd uses ##  as the default comment  characters.
	      You can use this option to specify different comment characters.
	      This is only necessary if you have to deal with  two  (or  more)
	      services of the same name.


       --pattern PATTERN
	      This  option can be used to select a service. You only need this
	      option if you have two (or more) services of the same name.


       --multi
	      If you want to disable/remove more than one entry at a time  you
	      should use this option. If you try to remove more than one entry
	      at a time without using this option  the	program  will  show  a
	      warning and asks the user if he want to continue.


       --add ENTRY
	      Add  an  entry  to  /etc/inetd.conf . A description of the ENTRY
	      format can be found in  the  inetd(8)  or  inetd.conf(5)	manual
	      pages (or just look at the /etc/services file). In order to pre
	      vent the shell from changing your ENTRY definition you  have  to
	      quote  the ENTRY using single or double quotes. You can use tabs
	      (the tab character or \t) and spaces to separate the  fields  of
	      the  ENTRY.  To  add  the  ENTRY	to  a  specific section in the
	      /etc/inetd.conf file please use the --group option  in  addition
	      to the --add option.

	      If  you  are trying to add an entry which already exists update-
	      inetd wont add the entry. For uncommented entries  it  will  do
	      nothing  and  for entries that are commented out by the comment-
	      chars (see option --comment-chars ) it will enable the  existing
	      entry.  If  you  want to completely replace an entry just remove
	      the entry with the --remove option first.


       --remove ENTRY
	      Remove an entry from /etc/inetd.conf . You  can  use  a  regular
	      expression to remove the entry.


       --enable SERVICE
	      Enable  SERVICE (e.g. ftp") in /etc/inetd.conf . If you want to
	      enable more than one SERVICE you can use a comma separated  list
	      of services (no whitespace characters allowed).


       --disable SERVICE
	      Disable SERVICE (e.g. ftp") in /etc/inetd.conf . If you want to
	      disable more than one SERVICE you can use a comma separated list
	      of services (no whitespace characters allowed).

       In  order  to prevent the shell from changing your ENTRY definition you
       have to quote the ENTRY using single or double quotes. You can use tabs
       (the  tab  character  or  \t)  and spaces to separate the fields of the
       ENTRY. If you want to enable/disable more than one SERVICE you can  use
       a  comma separated list of services (no whitespace characters allowed).


EXAMPLES
       Youve installed ssh (secure encrypting remote shell) and wish to  dis
       able its unencrypted cousins:

		update-inetd	    --comment-chars	   #	   --disable
       login,shell,exec,telnet

       Using a single # character as a comment-char prevents update-inetd to
       reenable the services on package upgrades.

       You  think  the	clock on your computer is often inaccurate and wish to
       make sure other computers cannot read it:

		update-inetd --disable time,daytime

       You get the clock fixed:

		update-inetd --enable time,daytime

       You hear a rumor that inetd is easily crashed via a SYN attack  against
       the time and daytime services, you want to turn off only their TCP ver
       sions, while leaving the analogous UDP services enabled:

		update-inetd --pattern tcp --disable time,daytime

       You just finished writing  a  POP3  server  and	want  to  install  the
       /etc/inetd.conf entry from the makefile:

		update-inetd --group MAIL --add \
	pop-3\t\tstream\ttcp\tnowait\troot\t/usr/sbin/tcpd\t/usr/sbin/in.pop3d
