It is becoming frequent that a dialog like this happens:
Me: SNMP_GET ifName.1
Agent: noSuchName (error-index: 2)
Me: "2", okay. Let me remove the second OID and try again. SNMP_GET
ifName.1
Agent: noSuchName (error-index: 2)
Me: "2", okay. Let me remove the second OID and try again. SNMP_GET
ifName.1
Agent: noSuchName (error-index: 2)
Me: "2", okay. Let me remove the second OID and try again. SNMP_GET
ifName.1
...
Here, "error-index" should be "1"; however, the agent is improperly
returning "2". The library should be able to handle such situations and not
be tricked into looping indefinitely.
What I want to implement is a retry counter that prevents this from
happening. I was going to add it to the whole netsnmp_ds piece with the
following options:
#define NETSNMP_DS_LIB_PDU_FIX_LIMIT 34 // If a request fails and the PDU
would historically be fixed and retried, only retry *this* many times.
Default: 5.
This will prevent infinite loops when asking for something and nothing is
ever going to be retrieved.
This is becoming important for my company, so I want to get on this and have
a patch out quickly.
Thoughts?
