New submission from varde: When trying to connect to a server which only supports TLS version 1.1 or 1.2, the following error is raised: ssl.SSLError: [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:598) For some reason, the SSL version is set to ssl.PROTOCOL_TLSv1 before initialisation and an SSL context is created in __init__, making any subsequent change to ssl_version useless. The only way to establish a successful connection is to pass a custom SSL context to the constructor. I think ssl_version should be settable at construction time before the context is created. I'm not sure exposing ssl_version is useful either, the documentation mentions it but it has no use after initialisation.
The following lines should also be changed: if self.ssl_version == ssl.PROTOCOL_TLSv1: resp = self.voidcmd('AUTH TLS') ---------- components: Library (Lib) messages: 233087 nosy: varde priority: normal severity: normal status: open title: ftplib.FTP_TLS's default constructor does not work with TLSv1.1 or TLSv1.2 type: behavior versions: Python 2.7, Python 3.2, Python 3.3, Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23111> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
