Yesterday, I found my python can't use urlopen function, not only module urllib,but also urllib2.
In console mode, try " file=urllib.urlopen('http://www.google.com'), it raises error like this:

Code:
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/lib64/python2.4/urllib.py", line 82, in urlopen
    return opener.open(url)
  File "/usr/lib64/python2.4/urllib.py", line 190, in open
    return getattr(self, name)(url)
  File "/usr/lib64/python2.4/urllib.py", line 313, in open_http
    h.endheaders()
  File "/usr/lib64/python2.4/httplib.py", line 798, in endheaders
    self._send_output()
  File "/usr/lib64/python2.4/httplib.py", line 679, in _send_output
    self.send(msg)
  File "/usr/lib64/python2.4/httplib.py", line 646, in send
    self.connect()
  File "/usr/lib64/python2.4/httplib.py", line 614, in connect
    socket.SOCK_STREAM):
IOError: [Errno socket error] (-2, 'Name or service not known')


I try to boot with livecd 2006.1, it's OK, and the same version of python. Also I re-emerged python, but still failed.

Sounds like a dns problem, the python module cannot lookup google.com's ip address.

It's not only python's problem, but also perl\ruby, all the same. :x
I don't know how to deal with it, it's system's problem.
If I use IP directly, it's OK

If you ping the hostname you are trying to connect to... what happens?

Does DNS work in firefox/etc.?
