regit / pynetfilter_conntrack Goto Github PK

Hi,
I have cloned your project and want to use it. However, I'm stuck in using Filter.
For example, in case I want to get the result like: "conntrack -L -p tcp -s 127.0.0.1", how can I use your library?

pynetfilter_conntrack can be installed with pip3.

$ sudo pip3 install pynetfilter_conntrack
Collecting pynetfilter_conntrack
Installing collected packages: pynetfilter-conntrack
Successfully installed pynetfilter-conntrack-0.7
$

The installed files are identical to what comes from pip (python 2) though:

$ DIR2="/usr/local/lib/python2.7/dist-packages/pynetfilter_conntrack"
$ DIR3="/usr/local/lib/python3.5/dist-packages/pynetfilter_conntrack"
$ find "${DIR2}" -name \*.py -printf "%f\n" | while read -r FILE; do diff -u "${DIR2}/${FILE}" "${DIR3}/${FILE}"; done
$ 

The code is not valid python3:

$ python3 -c 'import pynetfilter_conntrack'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/local/lib/python3.5/dist-packages/pynetfilter_conntrack/__init__.py", line 2, in <module>
    from pynetfilter_conntrack.tools import *
  File "/usr/local/lib/python3.5/dist-packages/pynetfilter_conntrack/tools.py", line 38
    shift = 0L
             ^
SyntaxError: invalid syntax
$

The code should either be forward-ported or be removed from pip3.

As described in the subject, contrack.catch() segfaults with libnetfilter_conntrack 1.0.5 and version 0.6 of the egg. It occurs with the provided example events.py and conntrack.py, too.

1. Looks like Official page is down. Is it an official repo?
2. setup.py points to the missing README (after the renaming it into the README.rst).
3. 0.5 version is released but the latest the pypi repo version is 0.4.2.
4. 0.5 version is trying to import missing nfct_conntrack_compare sysmbol.
5. 0.4.2 randomly fails into the maximum recursion depth exceeded.

The following files are missing in the PyPi 0.6 tarball:

• README.rst
• INSTLL
• ChangeLog

Traceback (most recent call last):
  File "setup.py", line 19, in <module>
    LONG_DESCRIPTION = open("README.rst").read() + open("INSTALL").read() + open("ChangeLog").read()
IOError: [Errno 2] No such file or directory: 'README.rst

I experience a segfault with pynetfilter_conntrack, reproducible with:

$ python -c "import pynetfilter_conntrack; pynetfilter_conntrack.Conntrack()"

Since issue #4 is specific regarding the call to catch() I believe this is not a duplicate.

Versions (Debian stretch):

• pynetfilter-conntrack: 0.7 (from pip)
• libnetfilter-conntrack: 1.0.6
• linux: 4.9.0

Here are an example python file and the gdb 'backtrace full' after the segfault.
