Strange, this does not work even on my Desktop:

$ python -c "import ssl"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named ssl

(Ubuntu 8.04.3 LTS)

Are you sure this is the correct way to use SSL? If possible, add here a
testcase that uses urllib2 on a https website and that works on a Desktop, but
not on Maemo.

a friend of mine told me to do that to see if Python was compiled with SSL
support...  still have to organize the code of my library, but I'll try to
provide you an example as soon as possibile.

This lines you'll read, works perfectly on my Ubuntu and not under Scratchbox

Isn't this just another case of bug 3755?

Strange, your example seems to work here:

the correct example should be: print cookie_response.read()
but anyway I don't reach that line... now I'm trying with another example that
doesn't use https, I'll let you know...

yes same error even without https :(

Hm, we seem to have different versions of "python2.5":

Mine came from extras-devel, but even after downgrading it manually it still
works - print cookie_response.read() outputs a long-ish HTML document titled
"simyo - My simyo. Login".

Can you put the above python lines in a script and strace it to see where it
fails?  In particular, does it open /etc/resolv.conf and send a DNS query to
the nameserver listed there?

hi, now the code is in a script. Could you please tell me how to execute the
"strace"? Thanks!

I found by myself :)
this is the output of strace: http://pastebin.com/m6fe5c281
I hope it can help you!

Thanks, it looks like a DNS problem after all - it sends a DNS query for
www.simyo.es, doesn't receive a reply, retries 3 times and finally aborts.

Is 127.0.0.1 the correct nameserver to use, and does "host www.simyo.es"
(apt-get install host if necessary) also fail?

of course 127.0.0.1 is not the correct nameserver. I copied my machine's
resolv.conf to /scratchbox/etc but this is not enough as I can see. Fixing the
dns, the script can run without problems.

This dsn problem is very annoying :(

Thanks, closing then.

It looks like it will be resolved sooner or later, but feel free to vote for
bug 3755 in the meantime.
