I am rushed to my feet to explore on SNMP v3. Actually this time with good materials such as Essential SNMP, Net-SNMP agent, and Snmp#Net, the progress is unexpectedly smooth.
I plan to provide a detailed report once I finish the first revision of full SNMP v3 support. Now I just focus on snmpget command line tool and already finish noAuthNoPriv and authNoPriv modes. Tomorrow I will try to finish authPriv mode.
1 2 3 snmpget -v=3 -l=noAuthNoPriv -u=lextm localhost 188.8.131.52.184.108.40.206.0 snmpget -v=3 -l=authNoPriv -u=lexli -a=MD5 -A=testpass localhost 220.127.116.11.18.104.22.168.0 snmpget -v=3 -l=authNoPriv -u=lextudio -a=sha -A=passtest localhost 22.214.171.124.126.96.36.199.0
Above are the test command lines I use to test snmpget against Net-SNMP agent, and you may notice that I choose a style similar to Net-SNMP snmpget.
I do not yet have a driver license, but I think now I have control of this v3 fast car. :)
