From ilya@math.ohio-state.edu

  perl -MCPAN -e shell

both from home and from work.

From home​: it finishes successfully, but LWP fetch fails, Net​::FTP
fetch succeeds.

From work​: LWP, NetFTP, ncftp and lynx fetches fail. (ncftp one is
understandable, since this version *requires* usage of ncftpget.)

At home​: OS/2, 5.005_53, fetches from ftp.metronet.com.

At work​: Solaris 7, 5.005_03, fetches from ftp.cs.colorado.edu (the
files *are* there).

Having no clue,

  ^^^^^^^^^^

Oops. Will check.

At home​: OS/2, 5.005_53, fetches from ftp.metronet.com.

metronet is currently taken off the MIRRORED.BY list because they are
facing difficulties. Better you try an alternative.

At work​: Solaris 7, 5.005_03, fetches from ftp.cs.colorado.edu (the

colorado just works from here.

Having no clue,

Neither.

No problem seen with Net​::FTP. Thus it is an LWP problem.

At work​: Solaris 7, 5.005_03, fetches from ftp.cs.colorado.edu (the

colorado just works from here.

Forgot to add​: both setups worked flawlessly (with LWP) beginning of
December.

i noticed the exact same thing the other night.. i believe it started after
i upgraded the CPAN bundle. i did a quick check of LWP (just a getprint)
at the time, but i haven't had a chance to look into it more.

Same behaviour with other sites. I tried again, and again found no
way to make CPAN emit debug-LWP tracing.

Another datapoint​:

lynx ftp​://ftp.cs.colorado.edu/pub/perl/CPAN/authors/01mailrc.txt.gz

works at home (OS/2), but not at work... I put the lynx trace into

Turned out to be a new firewall. Setting FTP_PASSIVE in environment
fixes it. However​: could CPAN.pm try passive mode itself?

And the problem of LWP not working from home remains... Any hint on
debugging?

I'm not sure if it should. There are many variations of firewalls.

If somebody wants to help Andreas/Graham out and hack firewall support
to CPAN.pm/libnet, I'd say ncftp is a good place to start, it knows
how to negotiate with *many* different firewall configurations. In
the configuration file the various options are even described in
writing, no need to look at the actual ncftp code (I hope).
