ACCESS_CONTROL

The ACCESS_CONTROL element specifies access from a list of IP allowed to access applications or services.

Syntax

<ACCESS_CONTROL> 
   [<ALLOW_FROM>...</ALLOW_FROM>][...]
</ACCESS_CONTROL>

Child elements

Zero or more ALLOW_FROM elements.

Usage

You use this element to specify what users have access to applications or services. By default, an application or a service is not accessible by anyone. It needs to be explicitly configured with ALLOW_FROM elements.

<ACCESS_CONTROL> 
  <ALLOW_FROM>127.0.0.1</ALLOW_FROM>
  <ALLOW_FROM>10.</ALLOW_FROM>
  <ALLOW_FROM>192.168.</ALLOW_FROM>
  <ALLOW_FROM>fdbd:2768:c176:1::323a</ALLOW_FROM> 
</ACCESS_CONTROL>

In this example, an application or a service is reachable from the localhost (127.0.0.1), and all IP addresses that begin with "192.168." or "10.", or the IPv6 address "fdbd:2768:c176:1::323a" .

Important:

Depending on the network configuration, it is not always possible to get the actual client IP address. If there is a proxy server between the client and the server, for example, the client IP address seen by the GAS may be the address from the proxy server.

Example configuring access control for demo applications

The default deployment of the demo application is specified by the resource res.access.control, which is defined with the value NOBODY by default.

To allow access from the localhost, in the JGAS configuration file you need to change the application element for gwc-demo from:

<!--Sample application for GWC-->
<APPLICATION Id="gwc-demo" >
    <EXECUTION>
      <PATH>$(res.path.fgldir.demo)</PATH>
      <MODULE>demo.42r</MODULE>
      <ACCESS_CONTROL>
          <ALLOW_FROM>$(res.access.control)</ALLOW_FROM>
      </ACCESS_CONTROL>
    </EXECUTION>
</APPLICATION>

To:

 <!--Sample application for GWC-->
<APPLICATION Id="gwc-demo" >
    <EXECUTION>
      <PATH>$(res.path.fgldir.demo)</PATH>
      <MODULE>demo.42r</MODULE>
      <ACCESS_CONTROL>
         <ALLOW_FROM>127.0.0.1 </ALLOW_FROM>
      </ACCESS_CONTROL>
    </EXECUTION>
</APPLICATION>
