<p>Latest FAQ revision - preparing for 5.5 release</p> <p><b>New page</b></p><div>Although an SNMP agent may support a wide range of management<br /> information, it is not necessarily appropriate to report the whole<br /> of this to every SNMP management station who asks for it. Some<br /> information may be sensitive, and should restricted to authorized<br /> administrators only. SNMP therefore includes mechanisms for<br /> controlling who has access to what information - both in terms of<br /> what can be seen, and (even more importantly) what can be changed.<br /> <br /> By default, the Net-SNMP agent starts up with a completely empty<br /> access control configuration. This means that &#039;&#039;&#039;no&#039;&#039;&#039; SNMP request<br /> would be successful. It is necessary to explicitly configure<br /> suitable access control settings, based on who should be granted<br /> access in that particular environment.<br /> <br /> If there are no access control entries configured (perhaps because<br /> no &lt;CODE&gt;snmpd.conf&lt;/CODE&gt; configuration file has been loaded, or it contains no<br /> access control settings), then the agent will not respond to any<br /> SNMP requests whatsoever. This is almost certainly not what was<br /> intended, so the agent reports this situation.<br /> <br /> See the [[FAQ:Agent_24|next entry]] for how to configure access control settings.</div>
