SNMP++ Get Error, SNMP++: SNMP request timed out

Hi,

> 2. If not to question (1), to make it possible, can I modify agent.cpp at

mabe I didn't understand the question, but here's my answer: you can
bind an agent to a specific interface:
#ifdef SNMP_PP_WITH_UDPADDR
	// bind localhost only -> agent will not be reachable from
	// outside
	// UdpAddress inaddr("127.0.0.1");
	UdpAddress inaddr("0.0.0.0");
	inaddr.set_port(port);
	Snmpx snmp(status, inaddr);
#else
	// bind on any address on local host
	Snmpx snmp(status, port);
#endif

> 3. Can you please explain the following output from agent:

The engineID is computed from the hostname and is printed out (in this
case) two times using hex and printable characters.

snmpGet sends its request to port 161 while the agent listens on port
4700...

Kind regards,
