[AGENT++] Net-SNMP master agent <-> AgentX++ sub agent compatibility

[john.edmonds at bt.com]

Hello Frank,
 
As far as I can tell the Net-SNMP workarounds are enabled, although I can't see that they are related to this particular issue.  Where in the agentX protocol code is the byte ordering determined, perhaps I can try some debugging?
 
Thanks,
John

Hello John,

The AgentX protocol requires that master as well as sub-agent can
operate on both byte orders (host and network). Thus, if it only
works when forcing the sub-agent to change its default order
then the master agent seems to have a bug.

BTW, have you enabled the NET-SNMP compatibility work-arounds
in agent++_def.h already?

Best regards,
Frank

To get things working I added the line to the open_session() method below to force a change to the default byte order.  With this change everything appears to work fine, without it nothing works....
