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  can't  add	an entry for the same service without removing the old
       one first.

       In accordance with the Debian Policy, update-inetd treats entries  that
       are  prefixed  with  a single `#' character as commented out by a user.
       This means that for a user to disable a service using update-inetd, and
       for  the	 service  to remain disabled after upgrades, the user must run
       update-inetd with --comment-chars  '#'  (see  relevant  option  below).
       Conversely,  package maintainer scripts should not override the default
       comment chars (and when they do, they must not use '#').

       Also note that --enable and --remove will not be acted upon for service
       entries	that  are commented out using anything but the value specified
       with --comment-chars (or the default value if none is specified).

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 ”#<off># ” 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. If you do use this option, it is your
	      responsibility to eventually remove the commented out entry.

       --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 prompt the user for an explicit confirmation.

       --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 /etc/inetd.conf).  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.   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 won't 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
       You've  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
       re-enable 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 --comment-chars '#' --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   --comment-chars	'#'  --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'

FILES
       /etc/inetd.conf /var/run/inetd.pid
