Braa is a mass snmp scanner. The intended usage of such a tool is of course making SNMP queries – but unlike snmpget or snmpwalk from net-snmp, it is able to query dozens or hundreds of hosts simultaneously, and in a single process. Thus, it consumes very few system resources and does the scanning VERY fast.
Braa implements its OWN snmp stack, so it does NOT need any SNMP libraries like net-snmp. The implementation is very dirty, supports only several data types, and in any case cannot be stated ‘standard-conforming’! It was designed to be fast, and it is fast. For this reason (well, and also because of my laziness ;), there is no ASN.1 parser in braa – you HAVE to know the numerical values of OID’s (for instance .220.127.116.11.18.104.22.168.0 instead of system.sysName.0).
