braa

Mass SNMP scanner for querying multiple hosts

TLDR

Walk the SNMP tree of a host

$ braa public@[ip_address]:[.1.3.6.*]

Query a subnet for a specific OID

$ braa public@[ip_range]:[.1.3.6.1.2.1.1.6.0]

Set a value using SNMP write

$ braa private@[ip_address]:[.1.3.6.1.2.1.1.6.0]=s'[workgroup]'

SYNOPSIS

braa [-2] [-v] [-t secs] [-a secs] [-r retries] [-d usecs] [-f file] community@host:oid...

braa is an ultra-fast mass SNMP scanner that can query multiple hosts simultaneously. Unlike traditional SNMP tools that process hosts sequentially, braa sends queries asynchronously, dramatically improving scan speed for large networks. It implements its own SNMP stack and requires numerical OIDs rather than symbolic names.The tool supports SNMP GET, SET, and WALK operations across multiple hosts in a single command.

PARAMETERS

-2

Use SNMPv2C (supports Counter64).

-t SECS

Response wait time in seconds (default: 2).

-a SECS

Deadline/overall timeout.

-r N

Retry count before giving up (default: 3).

-d USECS

Microsecond delay between packets.

-f FILE

Load queries from file.

-v

Verbose output.

SYNTAX

Queries use the format: [community@]host[-host2][:port]:OID[/id][,OID2...]- community: SNMP community string (e.g., public, private)- host: IP address or hostname (supports ranges like 10.0.0.1-10.0.0.50)- OID: Object Identifier, use * suffix for walksFor SET operations, append =type'value' where type is:- s: String- i: Integer- a: IP address- o: OID

CAVEATS

SNMP v1/v2c community strings are transmitted in plain text. Mass scanning may trigger security alerts or rate limiting. Ensure you have authorization before scanning networks. Not suitable for SNMPv3.
