=head1 DESCRIPTION
|
||
|
|
|
||
|
|
This module provides an abstracted interface to the esmith master
|
||
|
|
configuration database.
|
||
|
|
|
||
|
|
Unless otherwise noted, esmith::ConfigDB acts like esmith::DB::db.

This method creates a new record in the configuration database. As arguments,

|

it expects the key to the record, followed by a hash references with its
|
||
|
|
properties, including the type.

|
doesn't exist.

=head2 hosts_allow_spec ($service [,$daemon])
|
||
|
|
|
||
|
|
Given a service, return the string suitable for /etc/hosts.allow,
|
||
|
|
checking to see if the service is defined, whether it is enabled and
|
||
|
|
whether access is set to public, private, or localhost.
|
||
|
|
|
||
|
|
An optional argument provides the tag which appears in hosts.allow. If not
|
||
|
|
given, the service name is used.
|
||
|
|
|
||
|
|
For example, one of the following:
|
||
|
|
|
||
|
|
# 'oidentd' is not defined in the configuration database
|
||
|
|
# 'oidentd' is disabled in the configuration database
|
||
|
|
in.identd: 127.0.0.1
|
||
|
|
in.identd: 127.0.0.1 192.168.1.1/255.255.255.0
|
||
|
|
in.identd: ALL
|
||
|
|
|
||
|
|
And here's the hosts.allow fragment:
|
||
|
|
|
||
|
|
{
|
||
|
|
$OUT = $DB->hosts_allow_spec('oidentd', 'in.identd');
