Are you behind a firewall? Can you get to that url from a web browser?

05.07.2008 at 12:49PM PDT, ID: 21519756

lqwest:

No problem getting to the url from the web browser.

If I put in the code snippet below I get this on console:

C:\Perl\myscripts\html processing>perl url_ex_5.pl
500 Can't connect to www.perl.com:80 (Bad hostname 'www.perl.com')
Couldn't get it! at url_ex_5.pl line 5.
Internal Server Error
C:\Perl\myscripts\html processing>

                       
             use LWP::Simple;
my $uri = 'http://www.perl.com/CPAN/';
$content = get($uri);
print status_message(getprint($uri));
die "Couldn't get it!" unless defined $content;
 
print "Got content:\n$content\n";

I added a shebang line and everything came through ok on my system.

Make sure perl is in your path, and do a perl -V and make sure that the perl libs are in the @inc path

@INC:
c:/Perl/lib
c:/Perl/site/lib

if they are not you may need to add
use lib 'c:/perl/lib', 'c:/perl/site/lib';
above your use LWP::Simple;

05.09.2008 at 09:39AM PDT, ID: 21534536

lqwest:

I did perl -V and at the end out the output there was this ( so all looks fine as far as libraries go):
@INC:
C:/Perl/lib
C:/Perl/site/lib

From a command prompt, try:
ping www.perl.com

What output do you get?

05.09.2008 at 01:55PM PDT, ID: 21536350

lqwest:

ping www.perl.com generates this message on my screen:

C:\Windows\system32>ping www.perl.com
Ping request could not find host www.perl.com. Please check the name and try again.

lqwest:

The code works fine on my home pc. There must be some sort of firewall issue, although I do have a firewall at home also.

05.12.2008 at 02:16PM PDT, ID: 21550592

healthstatus:

It could also be a proxy server issue. Since you cannot ping from the command line, no DNS resolution is taking place. Try to ping 208.201.239.37 (one of the cpan mirrors IP addresses).

05.13.2008 at 04:01PM PDT, ID: 21560019

lqwest:

When I type: ping 208.201.239.37, I get this output ( from command line)

Pinging 208.201.239.37 with 32 bytes of data:
Reply from 157.56.184.1: Destination host unreachable.

I'm guessing you have a firewall blocking the traffic, with IE setup to use a proxy.
In Internet Explorer, select the menu Internet Options
Then select the tab Connections
Then click the button Lan Settings
Is the use a proxy server option turned on?
