Спасибо безвестному автору -- я процитирую его решение: I started seeing this error when I used CPAN to fetch stuff: Fetching with LWP: ftp://ftp.planetmirror.com/pub/perl/CPAN/modules/02packages.details.txt.gz LWP failed with code[400] message[FTP return code 000] Fetching with Net::FTP: ftp://ftp.planetmirror.com/pub/perl/CPAN/modules/02packages.details.txt.gz Couldn't fetch 02packages.details.txt.gz from ftp.planetmirror.com Fetching with LWP: ftp://cpan.nas.nasa.gov/pub/perl/CPAN/modules/02packages.details.txt.gz LWP failed with code[400] message[FTP return code 000] Fetching with Net::FTP: ftp://cpan.nas.nasa.gov/pub/perl/CPAN/modules/02packages.details.txt.gz Couldn't fetch 02packages.details.txt.gz from cpan.nas.nasa.gov Fetching with LWP: ftp://cpan.llarian.net/pub/CPAN/modules/02packages.details.txt.gz The fix is simple but not particularly easy to track down. This is likely happening because you are behind a NAT or firewall, and you need to do ftp in passive mode. Find your perls libnet.cfg file: % locate libnet.cfg /usr/local/share/perl/5.6.1/Net/libnet.cfg Edit that file and change the ftp_int_passive setting to 1.
