test-printable-longest-run

Introduction

This directory contains source code and data to check if inserting more than 20 bytes of contiguous ASCII character to a random payload can exempt the blocking.

To generate payloads for testing and ask detect.py to predict if each probe will get blocked or not:

make

Run the experiment:

make test

Compare the experiment results with what Algorithm 1 predicts:

make compare

• If there is no output to stdout and stderr at all, it means all experiment results match what detect.py (Algorithm 1) predicts.
• If there is any difference, it does not necessarily mean the detection rule does not hold. It may suggest a testing failure due to unreliable network. Simply re-run make test and then make compare again, to see if the same payload still have inconsistent results.

Historical experiment

On tencent-random-bj3, Feb 14, 2023:

printable.py will generate longest run printable of length 0 to 90.

./printable.py | tail -n+2 | ../detection-algorithm/detect.py

python3 printable.py | ./affected-payload -p 1000-2000 -repeat 25 -try 5 -worker 30 > test-printable.out

python3 analyze.py  < ./test-printable.out  | sort -k 1 -n > printable-results.out
