How do I overcome “Please login with USER and PASS.” “Passive mode refused.” errors? – when attempting a CPAN module install from within the cpan shell / cpan> prompt
From the output logs to the terminal it appears to be able to connect to an external Perl/CPAN ftp site from my work server but the remote machine is asking for username/password and is rejecting the connection due to my being in passive mode.
( I’ve tested http://ftp.perl.org separately and have been able to successfully login with user:anonymous password:anonymous )
So,
- Where do I put the username/password for CPAN program to supply to this remote perl/cpan machine? ( I assume the username is: anonymous, password: anonymous )
- Where do I make a setting to say that I’m in the correct mode (passive/non-passive) such that the remote perl/cpan machine will accept my connection
- Anything else I should do after I have resolved these issues?
Terminal output below, followed by Config.pm in CPAN folder on my server.
My machine is a CentOS Linux machine.
I’m trying to get Date::Calc successfully installed – my ultimate aim. Thanks.
Can’t find any answers after a search here and on the internet.

Update:
In response to daxim’s comment on his answer: “You can edit comments. – Either edit Config.pm, the key urllist is an arrayref of strings; or run o conf urllist at the CPAN prompt. – daxim 16 hours ago” – I tried your suggestions below, daxim:
First I tried:
cpan> o conf urllist
urllist
ftp://ftp.perl.org/pub/CPAN/
Type 'o conf' to view configuration edit options
Followed instructions (i.e. 3rd example bullet under heading “changing of list values: o conf KEY SHIFT|UNSHIFT|PUSH|POP|SPLICE|LIST” at http://search.cpan.org/~andk/CPAN-1.9402/lib/CPAN.pm#changing ) to add a http mirror from: http://www.cpan.org/SITES.html
cpan> o conf urllist http://mirror.ox.ac.uk/sites/www.cpan.org/ ftp://ftp.perl.org/pub/CPAN/
cpan> o conf urllist
urllist
ftp://ftp.perl.org/pub/CPAN/
Type 'o conf' to view configuration edit options
cpan>
So from the above, my HTTP mirror was not added. Can anyone offer some advice?
So then I tried: “Either edit Config.pm, the key urllist is an arrayref of strings; “:
The relevant snippet in Config.pm is:
'urllist' => [q[ftp://ftp.perl.org/pub/CPAN/]],
'wget' => q[/usr/bin/wget],
How would my arrayref look here – with my list of mirrors. i.e. tell me how I should edit it, please.
Update 2:
The instructions given in http://search.cpan.org/~andk/CPAN-1.9402/lib/CPAN.pm#changing (3rd example bullet), to add a URL to the urllist are incomplete, i.e. wrong, they missed out the push. The successful command is:
[root CPAN]# cpan
Terminal does not support AddHistory.
cpan shell -- CPAN exploration and modules installation (v1.7602)
ReadLine support available (try 'install Bundle::CPAN')
cpan> o conf urllist push http://mirror.ox.ac.uk/sites/www.cpan.org/
cpan> o conf urllist
urllist
ftp://ftp.perl.org/pub/CPAN/
http://mirror.ox.ac.uk/sites/www.cpan.org/
Type 'o conf' to view configuration edit options
cpan>
From:
http://www.perlmonks.org/?node_id=551175
Other important things:
Beforehand, must check if installing a new module, whether or not it also installs dependencies – i.e other modules – and if they are newer versions of those existing on the machine and therefore if their behaviour or interface has changed that would impact existing applications running on the machine: Does CPAN installing of new modules impact Perl-CGI applications on same live production server?
Update 3:
It would appear that editing the urllist is not persistent, as, on re-entering cpan after previous exit, only the ftp entry remains.
cpan> o conf urllist
urllist
ftp://ftp.perl.org/pub/CPAN/
Type 'o conf' to view configuration edit options
Overcome FTP problems (it’s a really stupid network protocol) by selecting a HTTP mirror.
