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 [email protected]: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 [email protected]:.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

                                                                   BRAA(1)
