Hi

i have a python script that uses urllib2 to download one file, it runs
ok in any pc but when urlopen is called in the ipod it show the
following error:

<urlopen error (4, 'Non-recoverable failure in name resolution')>

The complete stack:

>>> urllib2.urlopen("http://yahoo.com")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.5/urllib2.py", line 121, in urlopen
    return _opener.open(url, data)
  File "/usr/lib/python2.5/urllib2.py", line 380, in open
    response = meth(req, response)
  File "/usr/lib/python2.5/urllib2.py", line 491, in http_response
    'http', request, response, code, msg, hdrs)
  File "/usr/lib/python2.5/urllib2.py", line 412, in error
    result = self._call_chain(*args)
  File "/usr/lib/python2.5/urllib2.py", line 353, in _call_chain
    result = func(*args)
  File "/usr/lib/python2.5/urllib2.py", line 575, in http_error_302
    return self.parent.open(new)
  File "/usr/lib/python2.5/urllib2.py", line 374, in open
    response = self._open(req, data)
  File "/usr/lib/python2.5/urllib2.py", line 392, in _open
    '_open', req)
  File "/usr/lib/python2.5/urllib2.py", line 353, in _call_chain
    result = func(*args)
  File "/usr/lib/python2.5/urllib2.py", line 1100, in http_open
    return self.do_open(httplib.HTTPConnection, req)
  File "/usr/lib/python2.5/urllib2.py", line 1075, in do_open
    raise URLError(err)
urllib2.URLError: <urlopen error (4, 'Non-recoverable failure in name
resolution')>

this is the line where the error raises:

urllib2.urlopen("http://yahoo.com")

i can ping yahoo.com or google from ipod touch without problems, i
even tried urlopen with IP from google and yahoo and the got the same
result

is there any walkaround for this problem?

thanks in advance...
