# A little script to run tshark on capture file[s] (potentially ones that
|
|
# failed fuzz testing). Useful because it sets up ulimits and other environment
|
|
# variables for you to ensure things like misused ephemeral memory are caught.
|
|
# (I'm writing this after having my machine hang up for like 15 minutes because
|
|
# I wasn't paying attention while tshark was running on a fuzzed capture and
|
|
# it used all my RAM + swap--which was pretty painful.)
