Did you try running this, it doesn't display the urllist values as you suggest ("and see the url list") that would be o conf urllist, the command you suggest will initialise the urllist settings, prompt the user to connect to the internet so that cpan can suggest some mirrors or alternatively let them supply their own. Regardless, this won't help if they can't get internet access due to firewall restrictions, unless they host a cpan mirror accessable to them on their internal network.
