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

@ku4979p9 *** Update: I have suceeded to use pwncat with python3.11 through a virtual environment, as you propose here. however, it required me to built python3.11 fron source which took some time. @VainXploits this method should solve your problem since distutils is supported in python3.11
I still think that the maintainers of this repository (pwncat-cs) should make the adjusments in order to fit pwncat-cs also to python 3.12

Maybe if it has happened to someone, when you run: pwncat-cs -lp port and you get an error like: ImportError: No module named 'readline'

This error typically occurs because the readline module isn't installed in your Python environment.

sudo apt-get update
sudo apt-get install libreadline-dev

And if you get the error: distutils not found do the same procedure of @scmanjarrez
