I'm extending the main agent of Net-SNMP with a dynamically loadable sub-agent that manages private sub-tree MIB. The sub-agent retrieves the values of its objects communicating with an external equipment connected by serial RS232.
In other words, in the MODE_GET case of the scalar helper handler, I send a command to the serial port and waits for the answer from the external equipment. What should I do if the sub-agent doesn't receive any answer from the equipment after the timeout, or it receives a corrupted answer? Could SNMP_ERR_NOACCESS be the right choice, or SNMP_ERR_RESOURCEUNAVAILABLE, or a more general error like SNMP_ERR_GENERR? Another side margin question. Are there any differences between exceptions (noSuchObject, noSuchInstance and endOfMib) and error codes? Thanks for the answer. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
