Description
Generate a wav (mp3) file for packet data to differentiate data and ACK. Consider this module as a bonus module - the use may limited.
Options
-h, --help show this help message and exit
-v LOGLEVEL, --verbose=LOGLEVEL
set the loglevel (info, debug, warning, error)
-f CONNECTIONS, --data-flow=CONNECTIONS
specify the number of relevant ID's
-m MODE, --mode=MODE display packets or bytes in flight (default packets)
-o FILENAME, --outfile=FILENAME
name of the generated wav file (default: packets.wav)
-i DURATION_MIN, --duration-min=DURATION_MIN
minimum length of sound sample in seconds
-a DURATION_MAX, --duration-max=DURATION_MAX
maximum length of sound sample in seconds
-b LINK_BANDWIDTH, --bandwidth=LINK_BANDWIDTH
netto bandwith of channel in bit/s (default 100MB)
-c ACCELERATOR, --accelerator=ACCELERATOR
accelerator, 0.0001 times faster is default
-r CUT_GAP_PERIODES, --cut-gap-periodes=CUT_GAP_PERIODES
crop longer silence periodes to this, default 0.5
Example
captcp sound -f 1.1 --duration-max 0.05 -c 0.0005 -r 0.2 trace.pcap
