urllib on windows machines

william

I've got a strange problem on windows (not very familiar with that OS).

I can ping a host, but cannot get it via urllib (see here under).
I can even telnet the host on port 80.

Thus network seems good, but not for python ;-(.

Does any windows specialist can guide me (a poor linux user) to get
Network functionalitiies with python on windows ?

I'm runnning on Windows XP (sorry to not give more, I don't know the
equivalent of uname).
I'm using standard (msi) python-2.4.2

Thanks.

test.py contains the following lines:
"
import urllib
g=urllib.urlopen('http://www.google.com')
"
C:\Temp>python test.py

This part I can help you with:
import platform
platform.platform() 'Windows-2000-5.0.2195-SP4' # in my case platform.architecture() ('32bit', 'WindowsPE') platform.python_version() '2.4.2' platform.python_compiler() 'MSC v.1310 32 bit (Intel)' platform.python_build() (67, 'Sep 28 2005 12:41:11')
test.py contains the following lines:
"
import urllib
g=urllib.urlopen('http://www.google.com')
"
...

I'm on a Win2K 2.4.2 system, and Idle let's me do: import urllib
g = urllib.urlopen('http://www.google.com')
g.read(12)

'<html><head>'

So off-hand, I'd suspect some firewall thingie is getting in the way.
Can you "bless" \Python24\python.exe and \Python24\pythonw.exe as
applications allowed to do net traffic?

Thanks Scott

>>> import platform

(67, 'Sep 28 2005 12:41:11')

Bingo!!!!!
That's the problem: "Blocked outgoing TCP - Source Local: (1898)
Destination: 67.18.1.164: http(80)"

But why the "telnet www.google.com 80" is wroking ?
Why Firefox is running ?

Thanks.

Because (and I'm guessing here), telnet, ftp, firefox, ... are all
web-specific, and they are not regarded as possible monsters if they
try to connect to the web. I'd like the chance to deny all programs
that I don't expect to connect out the chance to do so, but there has
got to be a way to turn it off. Maybe there are some adjustments to
the program that emitted the "Blocked outgoing TCP - ..." message.

Something is clearly wrong. here's *my* XP system connecting to Google:

C:\Steve>python
Python 2.4.1 (#65, Mar 30 2005, 09:13:57) [MSC v.1310 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.

import urllib
f = urllib.urlopen('http://www.google.com')
len(f.read()) 2690

I suspect you may have a firewall problem: you could need to tell your
(XP Service Pack 2 personal) firewall it's OK for Python to make
outbound network connections.

Steve
