urllib2가 작동하지 않는 이유는 무엇입니까?

파이썬 2.6.5가 설치된 우분투 10.04 32 비트 시스템에 3 개의 다른 파이썬 스크립트를 설치했습니다.

이들 모두는 urllib2를 사용하며 항상이 오류가 발생합니다.

urllib2.URLError : 왜 그렇습니까?

예 :

>>> import urllib2
>>> response = urllib2.urlopen("http://www.google.com")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/urllib2.py", line 126, in urlopen
    return _opener.open(url, data, timeout)
  File "/usr/lib/python2.6/urllib2.py", line 391, in open
    response = self._open(req, data)
  File "/usr/lib/python2.6/urllib2.py", line 409, in _open
    '_open', req)
  File "/usr/lib/python2.6/urllib2.py", line 369, in _call_chain
    result = func(*args)
  File "/usr/lib/python2.6/urllib2.py", line 1161, in http_open
    return self.do_open(httplib.HTTPConnection, req)
  File "/usr/lib/python2.6/urllib2.py", line 1136, in do_open
    raise URLError(err)
urllib2.URLError: <urlopen error [Errno 110] Connection timed out>



>>> response = urllib2.urlopen("http://search.twitter.com/search.atom?q=hello&rpp=10&page=1")
Traceback (most recent call last):

    response = self._open(req, data)

업데이트 2 :

나는 집에 있고 라우터와 액세스 포인트를 사용하고 있습니다 :-. 그러나 방금 Firefox가 작동하지 않는다는 것을 알았습니다. 그러나 크롬, 시냅스 등은 작동합니다.

업데이트 3 :

먼저 시도 할 수있는 한 가지 테스트는 네트워크를 격리하는 것입니다.

시작 python -m SimpleHTTPServer하면 포트 8000에서 수신 대기하는 현재 디렉토리에 간단한 웹 서버가 생성됩니다.

그런 다음 테스트 할 수 있습니다.

>>> import urllib2
>>> response = urllib2.urlopen("http://localhost:8000")
>>> response.msg
'OK'

이렇게하면 문제가 파이썬인지 또는 네트워크 문제가 있는지 알 수 있습니다 (사례로 생각됩니다).
