Thanks Ned, I think this is indeed the case. Using os.setgroups with a list of group ids (one for the file access, one for the serial port) before switching user with os.setgid, os.setuid solved the problem. I think os.initgroups(username, gid) does just this, only is not yet available in my distro. It could be a feature of os that the groups of the user are set on a os.setuid call? Or would this break compatibility with the standard unix library behaviour? To David: Yes you are right, only it would have cost me quite a bit of time to strip the code, and I tried this code to see if the behaviour was consistent when using other daemon code. Next time I will post my own code. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue10032> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
