TypeError: '_sre.SRE_Match' object is not subscriptable

I can't run it.

This looks like a Python 3.5 issue - could you show us your python version?

[xhdix]

Python 3.5.3

Also, netfilterqueue cannot be installed in Python 3.7.3. What version did you test?

[ecthros]

All of our testing has been on python3.6. could you try that? We'll look into porting it to older versions of Python too.

I used: https://github.com/chriskuehl/python3.6-debian-stretch Then: # /usr/bin/python3.6 -m pip install -r requirements.txt And finally:

# /usr/bin/python3.6 engine.py --server-port 80 --strategy "[TCP:flags:PA]-duplicate(tamper{TCP:dataofs:replace:10}(tamper{TCP:chksum:corrupt},),)-|" --log debug

Thank You But it is better to support higher versions of Python too.

[ecthros]

Thanks so much for testing this out. Sorry to make you the guinea pig on this issue.

We have a fix for python3.5 and we'll be pushing that soon. The fix for python 3.7+ is tougher, but we'll work on it!

I'm leaving this issue open until the fix comes out as I imagine other people will run into it.

[xhdix]

You're welcome Thanks for making this amazing project an open source.

Hey @xhdix - I updated the parsing code to support Python 3.5. Let us know if you have any other issues!
