How to fix GET requests for "usmUserSecurity" in netsnmp?

snmpget -v 2c -c public myDevice usmUserSecurity

Returns:

SNMP-USER-BASED-SM-MIB::usmUserSecurityName.".q...s...."."__internal__" = STRING: __internal__

instead of NoSuchObject/Instance. The same behaviour happens for all the other columns in usm开发者_C百科UserTable.

Looks like the get requests act as getNext in this case. I am trying to fix this, but I can't seem to find the relevant part of code ( in the net-snmp code base ) which deals with these requests. Can someone assist?

You'd better capture the network packets and then see if the captured packets are special. As Net-SNMP is so "old" and stable, it is least likely that you discover a new bug.
