problems with a proxy & authentication

[Anthony_Barker]

I am having problems with python and our company's proxy server, which
requires  authentication.

here is the code I am using:

import urllib2 
proxy = urllib2.ProxyHandler({"http":"http://myname:mypass@proxyserver.company.com:8080/"})
opener = urllib2.build_opener(proxy) 
f = urllib2.urlopen('http://www.python.org') 

results
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/lib/python2.2/urllib2.py", line 138, in urlopen
    return _opener.open(url, data)
  File "/usr/lib/python2.2/urllib2.py", line 322, in open
    '_open', req)
  File "/usr/lib/python2.2/urllib2.py", line 301, in _call_chain
    result = func(*args)
  File "/usr/lib/python2.2/urllib2.py", line 785, in http_open
    return self.do_open(httplib.HTTP, req)
  File "/usr/lib/python2.2/urllib2.py", line 763, in do_open
    raise URLError(err)
urllib2.URLError: <urlopen error (101, 'Network is unreachable')>

Under windows error is the same except for the last line (and line
numbers)
URLError: <urlopen error (10051, 'Network is unreachable')>

Both perl and wget work. wget only supports Basic Authentication, so I
assume it is the same. Thinking it might be a network type issue I
changed the domain names to IP addresses. (results follow)

Any help would be appreciated................
