Ahh, sorry about that

So what is the way for making HTTP requests to websites with self-signed certificates from perl, if the user does not care about the CA chain validation?

In other way, what is the way for making LWP behave the same way it used to behave with pre-6 version?

--- Additional comment from Petr Pisar on 2014-05-26 11:20:51 GMT ---

There is no LWP environment variable or command line option to control that currently.

It's possible to pass ssl_opts => {SSL_verify_mode => IO::Socket::SSL::SSL_VERIFY_NONE} to LWP::UserAgent::new if you write your own LWP application.

This is also discussed in the upstream report.

The reason why the PERL_LWP_SSL_VERIFY_HOSTNAME seemed to work before is the IO::Socket::SSL < 1.950 defaulted to SSL_VERIFY_NONE. This has not been true since Fedora 20. Unfortunately Fedora 20 delivered the flawed LWP::Protocol::https, so it was not visible.

I agree with you that there should be way how to disable the certificate validation externally.

Comment 1 Jan Pazdziora 2014-05-26 13:40:54 UTC
The current PERL_LWP_SSL_VERIFY_HOSTNAME option for hostname validation is processed in /usr/share/perl5/LWP/UserAgent.pm so the component probably should be perl-libwww-perl.

Comment 2 Fedora End Of Life 2015-05-29 11:57:01 UTC
This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '20'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 20 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 3 Fedora End Of Life 2016-07-19 20:20:13 UTC
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this

Thank you for reporting this bug and we are sorry it could not be fixed.
