Hi Jeffrey,

This is the log of the agent when is started in debug mode, and later
Openser is started:

 /opt/net-snmp/sbin/snmpd -f -Dagentx -x tcp:localhost:705 2>&1
No log handling enabled - turning on stderr logging
registered debug token agentx, 1
agentx_register_app_config_handler: registering .conf token for
"agentxsocket"
agentx_register_app_config_handler: registering .conf token for
"agentxperms"
agentx_register_app_config_handler: registering .conf token for
"agentxRetries"
agentx_register_app_config_handler: registering .conf token for
"agentxTimeout"
Turning on AgentX master support.
agentx/master: initializing...
agentx/master: initializing...   DONE
NET-SNMP version 5.4
agentx/master: unexpected callback op 4
agentx/master: handle pdu (req=0x54fb3d2b,trans=0x0,sess=0x0)
agentx/master: open 0018efc0
agentx/master: opened 001ad130 = 5 with flags = a0
agentx/master: send response, stat 0 (req=0x54fb3d2b,trans=0x0,sess=0x0)
agentx_build: packet built okay

I have tried changing too the keywork agentXsocket to agentXSocket, and with
a minimal snmpd config, and still reports error:

# /opt/net-snmp/bin/snmpwalk -v 2c -c public localhost  .1.3.6.1.4.1.27483
OPENSER-REG-MIB::openser = No Such Object available on this agent at this
OID

And the snmpd log:

agentx/master: send response, stat 0 (req=0x54fb3d2f,trans=0x0,sess=0x0)
agentx_build: packet built okay
agentx/master: handle pdu (req=0x54fb3d30,trans=0x0,sess=0x5)
agentx/master: send response, stat 0 (req=0x54fb3d30,trans=0x0,sess=0x5)
agentx_build: packet built okay

Thanks!
