Hi,

well, the answer in in the source:

the session is set up with TnmSnmpCreateSession(), that initializes
the default address with 127.0.0.1 and then binds only to this
address/port combo. therefore with other adresses the port is
unreachable.

a responder session does not have -address configure option. maybe by
accident, maybe by a deeply hidden reason :-)

adding the -address option should cause no harm, because it does not
break the default behavior; a simple patch would be:

 static TnmTable responderOptionTable[] = {
+ { optAddress, "-address" },
     { optPort, "-port" },
     { optVersion, "-version" },
     { optCommunity, "-community" },

so the responder can listen to the port at any address:

> Tnm::snmp responder -address 0.0.0.0 -port 161 -community public

but then a non-default community string could be wise, but anyway.
