NAME¶
DebianNet.pm - create, remove, enable or disable entry in /etc/inetd.conf
SYNOPSIS¶
require DebianNet;
DebianNet::add_service($newentry, $group);
DebianNet::remove_service($entry);
DebianNet::enable_service($service, $pattern);
DebianNet::disable_service($service, $pattern);
DESCRIPTION¶
You can use the functions in
DebianNet.pm to to add, remove, enable or
disable entries in the
/etc/inetd.conf file. After the
/etc/inetd.conf file has been changed, a SIGHUP signal will be sent to
the inetd process to make sure that inetd will use the new
/etc/inetd.conf file. The functions 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.
The DebianNet functions treat entries that are commented out by a single '#'
character as entries that have been commented out by a user. It won't change
such entries.
For shell scripts you can also use the
update-inetd command. See
update-inetd(8) for further information.
VARIABLES¶
- $DebianNet::inetdcf = ”FILENAME";
- Use FILENAME instead of /etc/inetd.conf (e.g. for testing
purposes).
- $DebianNet::sep = ”#<off># ”;
- ”#<off># ” will be used 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.
- $DebianNet::multi = ”true";
- 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.
- $DebianNet::verbose = ”true";
- Explain what is being done.
FUNCTIONS¶
- DebianNet::add_service($newentry, $group);
- Add $newentry to the group $group of the /etc/inetd.conf file. If
the entry already exist it will be enabled (it will also detect entries
with different program options). Using $group is optional (the default
group is the group OTHER). If the group does not exist the entry will be
placed at the end of the file.
- DebianNet::remove_service($entry);
- Remove $entry from /etc/inetd.conf . You can use a regular
expression to remove the entry.
- DebianNet::enable_service($service, $pattern);
- Enable $service (e.g. ”ftp") in /etc/inetd.conf . Using
$pattern is optional. It can be used to select a service. You only need
this option if you have two (or more) services of the same name. An
example: you have three ftp entries in the /etc/inetd.conf file
(all disabled by default) and you want to enable the entry which uses the
wu-ftpd daemon. To do this, use the pattern ”wu-ftpd" (or any
other regular expression that matches this entry).
- DebianNet::disable_service($service, $pattern);
- Disable SERVICE (e.g. ”ftp") in /etc/inetd.conf . Using
$pattern is optional (see above).
