New submission from Ivan Sergeev <vserg...@gmail.com>: The SMTPServer class of the smtpd module creates a server socket with the IPv4 socket.AF_INET address family hardcoded, and this prevents it from later binding to an IPv6 local address.
This occurs on line 282 of smtpd.py for the Python 2.7 branch: http://hg.python.org/cpython/file/5319a4bf72e7/Lib/smtpd.py#l282 And on line 435 of smtpd for the Python 3.2 branch ( Lib/smtpd.py:435 ): http://hg.python.org/cpython/file/d937b527b76e/Lib/smtpd.py#l435 One IPv4/IPv6 agnostic solution is to look up provided local address with getaddrinfo(), and use one of the result's address family, socket type and address tuple for create_socket() and bind() at those lines: ... try: gai_results = socket.getaddrinfo(localaddr[0], localaddr[1]) self.create_socket(gai_results[0][0], gai_results[0][1]) # try to re-use a server port if possible self.set_reuse_addr() self.bind(gai_results[0][4]) self.listen(5) ... ---------- components: Library (Lib) messages: 160226 nosy: vsergeev priority: normal severity: normal status: open title: SMTPServer of smptd does not support binding to an IPv6 address type: behavior versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3, Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14758> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
