<modulesummary>Orber ACL operations</modulesummary>
<description>
<p>This module contains functions intended for analyzing Access
Control List (ACL) filters. The filters uses a extended format of
Classless Inter Domain Routing (CIDR).
For example, <c>"123.123.123.10"</c> limits
the connection to that particular host, while <c>"123.123.123.10/17"</c> allows
connections to or from any host equal to the 17 most significant bits. Orber
also allow the user to specify a certain port or port range, for example,
<c>"123.123.123.10/17#4001"</c> and <c>"123.123.123.10/17#4001/5001"</c>
respectively. IPv4 or none compressed IPv6 strings are accepted.</p>
</description>
<funcs>
<func>
<name>match(IP, Direction) -> boolean()</name>
<name>match(IP, Direction, GetInfo) -> Reply</name>
<fsummary>Verify if the IP address versus the current configuration</fsummary>
<type>
<v>IP = tuple() | [integer()]</v>
<v>Direction = tcp_in | ssl_in | tcp_out | ssl_out</v>
<v>GetInfo = boolean()</v>
<v>Reply = boolean() | {boolean(), [Interface], PortInfo}</v>
<v>Interface = string()</v>
<v>PortInfo = integer() | {integer(), integer()}</v>
</type>
<desc>
<p>If <c>GetInfo</c> is not supplied or set to false, this operation returns
a boolean which tells if the IPv4 or IPv6 address would pass the ACL
filter, defined by the <c>iiop_acl</c> configuration parameter, or not.
When <c>GetInfo</c> is set to true, a tuple which, besides the boolean
that tells if access was granted, also include the defined
interfaces and port(s). This operation requires that Orber is running and
can be used on a live node to determine if Orber has been properly configured.</p>
</desc>
</func>
<func>
<name>verify(IP, Filter, Family) -> Reply</name>
<fsummary>Verify if the IP address versus the Filter</fsummary>
<type>
<v>IP = string()</v>
<v>Filter = string()</v>
<v>Family = inet | inet6</v>
<v>Reply = true | {false, From, To} | {error, string()}</v>
<v>From = string()</v>
<v>To = string()</v>
</type>
<desc>
<p>This operation returns true if the IPv4 or IPv6 address would pass the
supplied ACL. If that is not the case, a tuple containing the accepted range
is returned. This operation should only be used for test purposes.</p>
</desc>
</func>
<func>
<name>range(Filter, Family) -> Reply</name>
<fsummary>Get range of Filter</fsummary>
<type>
<v>Filter = string()</v>
<v>Family = inet | inet6</v>
<v>Reply = {ok, From, To} | {error, string()}</v>
<v>From = string()</v>
<v>To = string()</v>
</type>
<desc>
<p>Returns the range of accepted IP addresses based on the supplied filter.
This operation should only be used for test purposes.</p>
