Hello. First of all, thank for reading my post.
I am facing problem with an agentx subagent that must support gets and puts.
But when I issue an snmpset command, nothing arrives to subagent.
I run master agent in this way:
./snmpd -c ../share/snmp/snmpd.conf -C -f -L -V -d -Dagentx
I see
subagent ==> OPEN PDU ==> snmpd
subagent < == RESPONSE (no error) <== snmpd
subagent ==> REGISTER (prefix=4 subtree=1.4908.3.20.5) ==> snmpd
subagent < == RESPONSE (no error) <== snmpd
I run: snmpset -v 1 -c public localhost 1.3.6.1.4.1.4908.3.20.5 i 1
Nothing hapends between snmpd and subagent.
Anybody knows what may be happening? Thank in advance.
