       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).

              Print version information on standard output and  exit  success-

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

       --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.

              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 SERVICE
              Remove SERVICE (e.g. telnet) from /etc/inetd.conf

       --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).

       You've installed ssh (secure encrypting remote shell) and wish to  dis-
       able its unencrypted cousins:

                update-inetd        --comment-chars        '#'       --disable

       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

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

                update-inetd        --group        MAIL        --add         \

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