First of all Dave, You have been really helpful (at least to me) lately. I truly appreciate it, and I hope I'm not a nag.
Now, This reminds me when you told me about the netsnmp_query_get() (included in net-snmp-5.3), 1) Does netsnmp_query_get() allow a sub-agent to query a different sub-agent ?(through the master of course, by sending some agentx-Get-PDU) 2) If not, is there any other API to do that? (not by using snmpget utility, which is not an API) Thanks, Erez. -----Original Message----- From: Dave Shield [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 17, 2006 3:59 PM To: Makavy, Erez (Erez) Cc: net-snmp-users@lists.sourceforge.net Subject: Re: What is the Callback transport?

It's a sort-of "internal loopback" mechanism, whereby the agent can re-query itself to retrieve (?or update?) another MIB instance value, without actually having to build-and-parse an SNMP request packet, or send it over the network. > 3) Do sub-agents by default ... use the callback transport? I don't think so. AFAIK, the main place this is used in in the DisMan Event-MIB module, to retrieve the values being monitored, or the payload for notifications sent. > 4) How is interprocess communication achieved with > the callback transport? It's not concerned with inter-process communication. This is used for *intra*-process communication - i.e. communication within a single (agent) process. > 5) Where can I read about? Use the source, Luke :-) I don't believe this is documented anywhere (though last time I said that, I was promptly corrected. Watch that space....)
