Problem Starting CPAN Shell with ftp.perl.org

monkfan has asked for the wisdom of the Perl Monks concerning the following question:

Dear fellow monks,

I wanted to start a new CPAN prompt installation in my new Linux PC. However I found this following problem especially in accessing ftp.perl.org.

How can I resolve this?

This is the message I got.

$ perl -MCPAN -e shell
/home/monkfan/.cpan/CPAN/MyConfig.pm initialized.
CPAN is the world-wide archive of perl resources. It consists of about
100 sites that all replicate the same contents all around the globe.
Many countries have at least one CPAN site already. The resources
found on CPAN are easily accessible with the CPAN.pm module. If you
want to use CPAN.pm, you have to configure it properly.

If you do not want to enter a dialog now, you can answer 'no' to this
question and I'll try to autoconfigure. (Note: you can revisit this
dialog anytime later by typing 'o conf init' at the cpan prompt.)

Are you ready for manual configuration? [yes] 

# ...EVERYTHING GOES SMOOTHLY UNTIL.....

If you're accessing the net via proxies, you can specify them in the
CPAN configuration or via environment variables. The variable in
the $CPAN::Config takes precedence.

Your ftp_proxy?  
Your http_proxy?  
Your no_proxy?  
You have no /home/ewijaya/.cpan/sources/MIRRORED.BY

You seem to have a network problem, either with `ftp` in general or when connecting to `ftp.perl.org`. Debug your network problem or configure CPAN to use another CPAN mirror manually. You can also fetch the MIRRORED.BY manually and put it in the right place.	[reply] [d/l] [select]

On a lot of corporate firewalls, FTP is blocked by default. Try HTTP instead. I don't think it's still the case with the most modern distributions, but the old CPAN was setup by default to only try FTP. Which is... aaaaargggghhhh!! just infuriating.	[reply]

Try HTTP instead. Hi Bart, How do you do that? Regards, Edward	[reply]

How do you do that? By adding HTTP URLs in the URL-list. The main tool to manage that list is "`o conf`" in the CPAN shell. You can see the current contents (under "urllist") with just "`o conf`", or, more limited in output, with "`o conf urllist`". You can replace the whole URL-list with, for example (this is the contents I have, which must have been put there by default): `o conf urllist http://ppm.activestate.com/CPAN http://cpan.perl.org` [download] You can also add a URL to the existing list with `shift` and `push`, like this: `o conf urllist push http://cpan.perl.org o conf urllist unshift http://cpan.perl.org` [download] or drop the first or last entry resp. with `o conf urllist shift o conf urllist pop` [download] You must save the changes with `o conf commit` [download] or you can rollback (after a disastrous mistake) with `o conf defaults` [download] HTH.
