Hello.
I'm trying to write a twisted client for MyProxy server. This grid service uses TLS. When using blocking calls, everything is ok. When trying to estabilish a twisted connection using reactor.connectSSL(host, port, f, contextFactory) with _the_same_ context in contextFactory, the error occures:
[Failure instance: Traceback (failure with no frames): <class 'OpenSSL.SSL.Error'>: [('SSL routines', 'SSL3_GET_RECORD', 'wrong version number')]
You can do it yourself by simply connecting to myproxy.cern.ch:7512
Is there anybody aware of such problem?
The server is using SSLv2. The traceback seems to indicate the context is set up for SSLv3. I can't tell how you created that context object, nor am I certain why one version of your code can establish a connection while the other cannot, but I would check the context object and make sure it is using either SSLv2 or SSLv23.
