<p></p> <p><b>New page</b></p><div>{{GoodAnswer}}<br /> <br /> == Question ==<br /> <br /> When I make a dynamic modification to the snmp agent it does not immediately update the /var/net-snmp/snmpd.conf file with the new data (example: user password changes, new trap destinations, vacm changes, etc). <br /> <br /> If the snmpd crashed, or some one did a &quot;kill -9&quot;, all my changes are lost.<br /> <br /> == Answer ==<br /> <br /> You&#039;re right! It doesn&#039;t update it right away. This is primarily because it was originally conceived as an expensive operation and not worth doing right away. The agent will save the data upon a proper shutdown, but it won&#039;t if it doesn&#039;t shutdown properly.<br /> <br /> &#039;&#039;&#039;Note:&#039;&#039;&#039; &#039;&#039;You should never kill -9 any daemon except as a last resort!!&#039;&#039;<br /> <br /> === Solution: Force a Save ===<br /> <br /> You can, actually, force the snmpd daemon to save the data. To do this, send a set request to versionSavePersistentData.0 with an integer value of 1.<br /> <br /> snmpset HOST versionSavePersistentData.0 = 1<br /> <br /> This will force an immediate save of the data.<br /> <br /> [[Category:agent]]<br /> [[Category:persistence]]</div>
