dhcpcanon's Issues
py.test fails with import error
I'm probably doing something wrong here, I have this test case which basically just runs py.test inside the release tar ball:
check() {
cd "${pkgname}-${pkgver}"
py.test
}
and I get this error (the environment is clean, so dhcpcanon isn't installed yet and therefore can't be imported):
==> Starting check()...
ImportError while loading conftest '/build/dhcpcanon/src/dhcpcanon-0.8.5/tests/conftest.py'.
tests/conftest.py:6: in <module>
from dhcpcanon.dhcpcap import DHCPCAP
E ModuleNotFoundError: No module named 'dhcpcanon'
==> ERROR: A failure occurred in check().
This seems to be related to this answer: https://stackoverflow.com/a/46222631

Python 2 Support
This project in the early stages supports python 2. Now their is no python 2 support anyway. This is caused by two bugs that simply got ignored and not solved.
#21
Is a bug that appears because a int parsing do not work correctly. load_entry_point can not be found in source code anymore their is not reason for switch the version for a trivial error like this.
#15
Is a bug that using a python3 parameter to the function open this have something todo with encoding and can be used in python2 too
I basically miss the cool looking version badges in the README

Possibilities:
- drop privileges?
- linux capabilities?
- apparmor profile?

Is this project dead?
There hasn't been a commit since 2018 and https://github.com/juga0/dhcpcanon#current-status says:
WIP, still not recommended for end users.
Does that mean this project is dead? Are there any security issues? Should it still be used?
Integrate with system managers
Shorten time when IP address is asked for
Currently as per the spec, there is a variable 10 - 60 second delay before dhcpcanon asks for an IP address from the router. This is a relatively poor users experience given what people are used to (a few seconds usually).

Compatibility with Python3
`adduser` is a Debian-ism
adduser is a Debian frontend for useradd. It's not available on e.g. Archlinux. I don't have a proposed solution; I'm not sure if there's a nice portable way to add a system user.
pyroute2-based interface configuration never removes addresses
They keep accumulating on the interface:(
The pyroute2 internal configuration is preferred to using the dhcpc script, right?
