python - error - urllib2: leyendo https url failure

urllib2.urlopen timeout

Question

Este código falla en mi Ubuntu, pero funciona bien en otros hosts.

>>> from urllib2 import urlopen
>>> urlopen("https://courtapps.utcourts.gov/XchangeWEB/login")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/urllib2.py", line 126, in urlopen
return _opener.open(url, data, timeout)
File "/usr/lib/python2.7/urllib2.py", line 400, in open
response = self._open(req, data)
File "/usr/lib/python2.7/urllib2.py", line 418, in _open
''_open'', req)
File "/usr/lib/python2.7/urllib2.py", line 378, in _call_chain
result = func(*args)
File "/usr/lib/python2.7/urllib2.py", line 1215, in https_open
return self.do_open(httplib.HTTPSConnection, req)
File "/usr/lib/python2.7/urllib2.py", line 1177, in do_open
raise URLError(err)
urllib2.URLError: <urlopen error [Errno 1] _ssl.c:504: error:1408F119:SSL
routines:SSL3_GET_RECORD:decryption failed or bad record mac>

¿Cuál es el motivo y cómo solucionarlo? Siento que algo está mal con OpenSSL , tengo v1.0.1 instalado.

El controlador personalizado de SSLv3 resuelve el problema:

import httplib, ssl, urllib2, socket
class HTTPSConnectionV3(httplib.HTTPSConnection):
def __init__(self, *args, **kwargs):
httplib.HTTPSConnection.__init__(self, *args, **kwargs)
def connect(self):
sock = socket.create_connection((self.host, self.port), self.timeout)
if self._tunnel_host:
self.sock = sock
self._tunnel()
try:
self.sock = ssl.wrap_socket(sock, self.key_file, self.cert_file, ssl_version=ssl.PROTOCOL_SSLv3)
except ssl.SSLError, e:
print("Trying SSLv3.")
self.sock = ssl.wrap_socket(sock, self.key_file, self.cert_file, ssl_version=ssl.PROTOCOL_SSLv23)
class HTTPSHandlerV3(urllib2.HTTPSHandler):
def https_open(self, req):
return self.do_open(HTTPSConnectionV3, req)
# install opener
urllib2.install_opener(urllib2.build_opener(HTTPSHandlerV3()))
if __name__ == "__main__":
r = urllib2.urlopen("https://courtapps.utcourts.gov/XchangeWEB/login")
print(r.read())
