create, remove, enable or disable entry /etc/inetd.conf
update-inetd [option...] command argument
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).
--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).
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.
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.
update-inetd uses "#
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'
