My apologies if this has been discussed before, but I couldn't find it
in a quick search of the archives.
I am trying to build the sub-agent example on the NetSNMP Wiki on a
Win32 system. I am currently using the NetSNMP v5.5 binary distribution
for Win32.
After some judicious searching and debugging, I was able to determine
that I had to add a line to the example-daemon.c file to specify where
the subagent should contact the master agent:
netsnmp_ds_set_string(NETSNMP_DS_APPLICATION_ID,
NETSNMP_DS_AGENT_X_SOCKET, "tcp:localhost:705");
After which I started getting timeouts, instead of no OID, when
attempting to pull down the example variable:
C:\My_Data\Visual Studio 2008\Projects\AuxP_App\SNMPTest>snmpget -v 2c
-c public
localhost NET-SNMP-TUTORIAL-MIB::nstAgentSubagentObject.0
Timeout: No Response from localhost.
I turned on some debugging, and it looks like the sub-agent is receiving
the GET request, but is never responding. Does anyone have any idea why
the default handler might not be returning anything? I'd rather use the
default handler if I can, but I'll write my own if necessary. Here are
the debug printouts from the run:
Master agent:
