That's the application on the central server, you mean? > > 1. I've choosed the Iterator solution, as explained when running mib2c > > (the data are held outside from the agent itself).

When you are writing a subagent then the subagent acts as > agent, so you are holding all data inside the (sub)agent (in that linked list) I'm not sure I agree. Yes - the data is held within the same application binary as the (sub)agent. But you could reasonably regard the subagent as a semi-self-contained unit within the wider application. As regards the choice of MIB helper, what's relevant is whether the data for the table is maintained by SNMP subagent code (i.e. one of the table data helpers), or "external" to the Net-SNMP-provided code. If the table data is stored in a linked list, and manipulated by your main application code - then this is effectively "external" to the SNMP sub-unit, so the iterator is a reasonable choice. Otherwise, you're really looking at taking a second copy of the same data within the application, specifically for the SNMP processing. If things change as quickly as you imply, this might not be the best approach. Dave ------------------------------------------------------------------------- Take Surveys. Earn Cash.
