# Randpkt testing script for TShark
|
||||
#
|
||||
# This script uses Randpkt to generate capture files with randomized
|
||||
# content. It runs TShark on each generated file and checks for errors.
|
||||
# The files are processed repeatedly until an error is found.
|
||||
|
||||
# Tweak the following to your liking.

||||
