Sometimes the HTTP Error is a 400 Bad Request, but 99% of the time a 405. I've testet openSuSE 12.2 with python 2.7.3 too, not working.

I don't know, what to provide more on information, please contact me, if you need more.

That's a non-public IP, so you'll have to provide a trace of the http traffic.  It is likely the error is correct, and is reported only post 2.7.0 because a bug was fixed.

ok, here's a run with debuglevel for the headers:

the IP is private and even for testing I can't put it in a public IP range, as the device is an IP Phone with a custom firmware (Siemens optiPoint 420).

It looks like the data input is the same in both cases. (Although why does your second example show '<urllib2.Request instance at 0x90d878>'?  Does urllib2 really output that as part of the debug output?)  It is hard to see what could be causing the divergence in response here.  Is it possible for there to be something in the SSL setup that triggers a different response from your server?

Any chance you could try Python 3.2 or 3.3 just to see if there is a difference there?

By using "openssl s_client -connect 172.23.6.222:443" you can open a telnet-like session (but using SSL) to your server, and try to type/paste an HTTP request there. That would help check whether it's a Python problem, or something else due to OpenSSL changes.

python3 example, not working on both machines (3.2.1 on openSuSE 12.1 and 3.1.3 on openSuSE 11.4)

ok actually it isn't working either with curl or wget. So probably this is not a python problem, it seems more something in the underlying libs:

No idea anymore :/ But I fear you can close this ticket...
