In this situation, the subagent is essentially acting in the same way as the command-line tools. The fact that it's talking to the same master agent is irrelevant here - you're opening a completely separate "client" connection, that just happens to be to the same process. So the code for opening a connection is the same as that from any other client application. See the main() method of (e.g.) apps/snmpset.c for details. That code also constructs the SET PDU (and calls 'snmp_synch_response()') directly, rather than via the netsnmp_query_set() API. If you want to use this API instead, then you'd build the varbind list using snmp_varlist_add_variable() rather than snmp_pdu_add_variable() - but the idea is essentially the same, (In fact, snmp_pdu_add_variable actually invokes snmp_varlist_add_variable anyway) Dave ------------------------------------------------------------------------------ Better than sec?
