distutils not found

[VainXploits]

Bug Description

After installing pwncat using pip, facing an issue saying distutils not found

pwncat version

Can't provide version because I can't run pwncat-cs because distutils is not found

Target System (aka "victim")

My own kali box

Above is the error that pops up whenever pwncat-cs is run with any flag after it.

This is a problem with latest python version in kali (3.12).
If you have a previous python version, then you can try installing setuptools and see if that fixes the problem for you.

pip install setuptools

If your python version is 3.12, then you'll need to do some manual updates:
First, install a pwncat with the new setuptools changes

pip install --force-reinstall git+https://github.com/scmanjarrez/pwncat

Next you need to update a pwncat dependency with the changes applied for setuptools

pip install git+https://github.com/Pylons/zodburi@modernize-python-versions

Pip will complain but ignore it, by this time pwncat should work again

The warnings apparently can be removed by removing paramiko-ng and installing paramiko package instead. P.S: Haven't tested enough to confirm that this is an in-place replacement.

Hi all.

1. to fix "No module named 'distutils'" error - add setuptools = "^70.0" to pyproject.toml in [tool.poetry.dependencies] section;
2. to fix "TripleDES \ Blowfish warnings" add cryptography = "^36.0.0" to pyproject.toml in [tool.poetry.dependencies] section;
3. use pipx install /path/to/pwncat/cloned/git/dir.

Hi, I Have the same problem, because I am using kali linux with python 3.12, and unfortunately, python 3.11 or 3.10 in which distutils wasn't deprecated yet, is not available in kali linux directly.

installing setuptools doesn't fix the problem.

anyway , since the author says in the README file of the tool:

pwncat requires Python 3.9+ on Linux

I suggest replacing distutils with something that works along all python3.9+ versions
