UPDATE-INETD(1)       User Contributed Perl Documentation      UPDATE-INETD(1)

NAME
       update-inetd - create, remove, enable or disable entry /etc/inetd.conf

SYNOPSIS
       update-inetd [option...] command argument

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. 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 cannot 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).

COMMANDS
       --add entry-line
           Add an entry to /etc/inetd.conf. A description of the entry-line
           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-line definition you have to quote the
           entry-line using single or double quotes. You can use tabs (tab
           character or \t) and spaces to separate the fields of the entry-
           line. To add the entry-line to a specific section in the
           /etc/inetd.conf file please use the --group option.

           If you are trying to add an entry which already exists, update-
           inetd will not 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 command first.

       --remove entry-regex
           Remove an entry-line matching entry-regex (e.g. "telnet") from
           /etc/inetd.conf. The entry-regex will be anchored at the beginning
           of the entry line.

       --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).

OPTIONS
       --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".

           This option is only relevant with the --add command.

       --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.

           This option is not relevant with the --add command.

       --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.

       --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.

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

       --verbose
           Explain what is being done.

       --debug
           Enables debugging mode.

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

       --version
           Print version information on standard output and exit successfully.

EXAMPLES
       You have installed ssh (secure encrypting remote shell) and wish to
       disable 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
       versions, 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
