Rémy Léone added the comment: The question I'm the most interested about is why depending on what the bytes object contains I get a different result. In one case the bytes are written fine to the TUN interface file descriptor and in the other case I get an Errno22. My assumption is that the bytes to write are completely opaque for Python.
My current workaround is mainly to start the bytes I want to send to my tun interface with a non-0 byte. Something strange that I have also noticed using strace python simple_incorrect.py is that I get EINVAL errors in the second case while I didn't change the mode with which I open the tun. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30430> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
