For anyone using LWP::Protocol::https based Perl tools, TLSv1 can be
forced with:
my $thing = whatever->new(
ssl_opts => { SSL_version => 'TLSv1' },
);
Another site that fails is paypal:
$ openssl s_client -connect www.paypal.com:443
CONNECTED(00000003)
write:errno=104
vs
$ openssl s_client -tls1 -connect www.paypal.com:443
CONNECTED(00000003)

HTTPS requests fail on some sites on Ubuntu 12.04

Confirmed
Bug description:
This week, HTTPS connections from a Python script I wrote started
giving me this error:
urllib2.URLError: <urlopen error [Errno 8] _ssl.c:497: EOF occurred in
violation of protocol>
This used to work up until some three days ago and still works on
other Ubuntu versions, but not in other Python versions on Precise. I
was suspecting this was a bug in Python, but a guy on AskUbuntu (
http://askubuntu.com/questions/116020/python-https-requests-urllib2
-to-some-sites-fail-on-ubuntu-12-04-without-proxy/116059#116059 )
found out this happens using the openssl command line tool too:
$ openssl s_client -connect www.mediafire.com:443
But succeeds if forcing TLS 1 with the -tls1 argument.
