 <div class="paragraph">
 <p>The configuration of all server services (network facing services) is
 done in xinet.d style config files. The telnet shell is controlled via
 the $OPENEJB_HOME/conf/telnet.properties file. This file is created for
 you automatically after the first time OpenEJB boots.</p>

 <p>Then restart OpenEJB.</p>
 </div>
 <h1 id="_restricting_access" class="sect0">Restricting Access</h1>
 <div class="paragraph">
 <p>It is unlikely you want just anyone to be able to login and execute
 commands. While you can&#8217;t restrict access on a user basis, yet, you can
 restrict access to specific hosts. Host based access control (HBA) is a
 built-in part of any Server Service in OpenEJB and the Telnet Service is
 no different. This is done with the 'only_from' property, which like the
 rest of the file is a direct copy of the xinet.d syntax for HBA.</p>
 </div>
 <div class="paragraph">
 <p>For an example to restrict access to the localhost, you could configure
 the Telnet Service like this:</p>
 </div>
 <div class="listingblock">
 <div class="content">
 <pre class="highlight"><code class="language-properties" data-lang="properties">    server  = org.openejb.server.telnet.TelnetServer
     bind    = 127.0.0.1
     port    = 4202
     disabled    = false
     threads = 5
     only_from   = localhost</code></pre>
 </div>
 </div>
 <div class="paragraph">
 <p>If you wanted to restrict access to localhost <em>and</em> say the hosts
 192.168.1.207 and 192.168.1.16, you can simply add them to the list.</p>
 </div>
 <div class="listingblock">
 <div class="content">
 <pre class="highlight"><code class="language-properties" data-lang="properties">    server  = org.openejb.server.telnet.TelnetServer
     bind    = 127.0.0.1

	<h1 id="_restricting_access" class="sect0">Restricting Access</h1>
	<div class="paragraph">
	<p>It is unlikely you want just anyone to be able to login and execute
	commands. While you can’t restrict access on a user basis, yet, you can
	restrict access to specific hosts. Host based access control (HBA) is a
	built-in part of any Server Service in OpenEJB and the Telnet Service is
	no different. This is done with the 'only_from' property, which like the
	rest of the file is a direct copy of the xinet.d syntax for HBA.</p>
	</div>
	<div class="paragraph">
	<p>For an example to restrict access to the localhost, you could configure
	the Telnet Service like this:</p>
	</div>
	<div class="listingblock">
	<div class="content">
	<pre class="highlight"><code class="language-properties" data-lang="properties"> server = org.openejb.server.telnet.TelnetServer
	bind = 127.0.0.1
	port = 4202
	disabled = false
	threads = 5
	only_from = localhost</code></pre>
	</div>
	</div>
	<div class="paragraph">
	<p>If you wanted to restrict access to localhost <em>and</em> say the hosts
	192.168.1.207 and 192.168.1.16, you can simply add them to the list.</p>

	<pre class="highlight"><code class="language-properties" data-lang="properties"> server = org.openejb.server.telnet.TelnetServer
	bind = 127.0.0.1
	port = 4202
	disabled = false
