BlabberMouth is a software hub for various types of connections. The typical use case is a set of devices that must be communicate to each other. BlabberMouth connects to each device, and when a device sends data to BlabberMouth, the latter sends to it to all the other devices.
./blabbermouth <-s SIZE> [-f FILE]... [STREAM]...
./blabbermouth scan
data repeater on various types of connections.
BlabbermMuth has two operational modes: streaming and scanning.
In streaming mode, BlabberMouth connects to each STREAM passed as
command line parameter and/or in FILE. Every time a message is sent
by one of the peers over a stream, BlabberMouth collects the data and
sends it over the other streams.
Each message managed by BlabberMouth must be exactly SIZE bytes
long, so the -s option is required.
The syntax for stream descriptors is: ID:TYPE:VERBOSE:DATA, where
ID is a unique identifier for the stream; TYPE is a case-sensitive
string such as tcp, udp, bt, or xbee; VERBOSE is a flag
(0/1) to establish whether BlabberMouth should log when
sending/receiving messages on the console; and DATA is a
colon-separated string of fields that specify how to connect to the
stream.
Supported stream descriptors:
ID:tcp:VERBOSE:SERVER:PORT A TCP connection to SERVER on PORT
ID:udp:VERBOSE:SERVER:PORT A UDP connection to SERVER on PORT
ID:bt:VERBOSE:rfcomm:CHANNEL An RFComm Bluetooth connection on CHANNEL
Options:
-s SIZE | --size SIZE The size (in bytes) of a message
-f FILE | --file FILE A file containing one stream descriptor per line
In scanning mode, Blabbermouth looks for Bluetooth devices to connect to and prints a list of available devices. BlueZ must be installed for Bluetooth to be supported.
To make sure BlabberMouth works, you could try the following tests.
Open three terminals. In the first write:
nc -l 12345
In the second write:
nc -l 12346
In the third write:
./blabbermouth -s 5 1:tcp:1:localhost:12345 2:tcp:1:localhost:12346
Now type a five-character string in either of the first two terminals,
and press enter. The other terminal where nc is running should show
what was typed in the other terminal.
Open three terminals. In the first write:
nc -ul 12345
In the second write:
nc -ul 12346
In the third write:
./blabbermouth -s 5 1:udp:1:localhost:12345 2:udp:1:localhost:12346
Now type a five-character string in either of the first two terminals,
and press enter. The other terminal where nc is running should show
what was typed in the other terminal.
