libtaxii client examples with *current* services?

[olyerickson]

When testing the following example client code against the MITRE test service we see errors

The code:

import libtaxii as t
import libtaxii.messages_11 as tm11
import libtaxii.clients as tc
from libtaxii.common import generate_message_id
from libtaxii.constants import *
from dateutil.tz import tzutc

client = tc.HttpClient()
client.set_use_https(True)
client.set_auth_type(tc.HttpClient.AUTH_BASIC)
client.set_auth_credentials({'username': 'MyUsername', 'password': 'MyPassword'})

discovery_request = tm11.DiscoveryRequest(generate_message_id())
discovery_xml = discovery_request.to_xml(pretty_print=True)

http_resp = client.call_taxii_service2('taxiitest.mitre.org', '/services/discovery/', VID_TAXII_XML_11, discovery_xml)
taxii_message = t.get_message_from_http_response(http_resp, discovery_request.message_id)
print taxii_message.to_xml(pretty_print=True)

The error...

Traceback (most recent call last):

Thanks, @olyerickson . I need to figure out what happened with that server.

taxiitest.mitre.org is no longer active. hailataxii.com provides most (but not all) functionality we were demonstrating with the examples, so @clenk updated the examples to use that instead (in #211). If you know of other public TAXII servers we can use, let us know. Thanks again, @olyerickson.
