NAME

braa - Mass SNMP scanner

SYNOPSIS

braa [-2] [-v] [-t <s>] [-f <file>] [-a <time>] [-r <retries>] [-d <delay>] [querylist1] [querylist2] ...

DESCRIPTION

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 .1.3.6.1.2.1.1.5.0 instead of system.sysName.0).

OPTIONS

-h

Show help.

-2

Claim to be a SNMP2C agent.

-v

Show short summary after doing all queries.

-x

Hexdump octet-strings

-t <s>

Wait <s> seconds for responses.

-d <s>

Wait <s> microseconds after sending each packet.

-p <s>

Wait <s> milliseconds between subsequent passes.

-f <file>

Load queries from file <file> (one by line).

-a <time>

Quit after <time> seconds, independent on what happens.

-r <rc>

Retry count (default: 3).

QUERY FORMATS

GET: [community@]iprange[:port]:oid[/id]

WALK: [community@]iprange[:port]:oid.*[/id]

SET: [community@]iprange[:port]:oid=value[/id]

EXAMPLES

$braa public@10.253.101.1:161:.1.3.6.*

Walk the SNMP tree of host 10.253.101.1 with public string querying all OIDs under .1.3.6:

$braa 10.253.101.1-10.253.101.254:.1.3.6.1.2.1.1.6.0

Query the whole subnet 10.53.101/24 of for system.sysLocation.0

$braa private@10.253.101.1:.1.3.6.1.2.1.1.6.0=sMy network

Tries to set the value of system.sysLocation.0 to "My network" at host 10.253.101.1
