DebianNet.pm - create, remove, enable or disable entry in /etc/inetd.conf

require DebianNet;

DebianNet::add_service($newentry, $group);

DebianNet::remove_service($entry);

DebianNet::enable_service($service, $pattern);

DebianNet::disable_service($service, $pattern);

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.

$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.

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).
