in reply to ftp problem on cpan client on windows with strawberry perl

This is quite possibly a problem I noted before:
[Perl]# host ftp.cpan.ddns.develooper.com ftp.cpan.ddns.develooper.com has address 149.20.20.135 ftp.cpan.ddns.develooper.com has address 168.143.19.69 [Perl]# host 149.20.20.135 135.20.20.149.in-addr.arpa is an alias for 135.128-27.20.20.149.in-add +r.arpa. 135.128-27.20.20.149.in-addr.arpa domain name pointer mirrors1.kernel. +org. [Perl]#
Note the mirrors1.kernel.org. I found that they had (have?) an improperly configured FTP server. The problem is in the the last line of a multi-line reply, and a missing space:

Ref: CPANplus 5 minute timeout>

They were notified, but no response was ever received.

It is always better to have seen your target for yourself, rather than depend upon someone else's description.
