Hello,<div><br></div><div>attached is the patch for the implementation of SNMPv3. I&#39;ve been testing it on my system and devices, and it seems to be working properly.</div><div>Since it&#39;s a core function of the soft, I guess it would be good that other people give it a try before it is committed.</div>

<div><br></div><div>I use NET-SNMP version: 5.4.3.</div><div><br></div><div>Be careful that a few files use direct calls to net-snmp instead of calling observium library functions. It means that those calls will not work with an snmpv3 device.</div>
