I been trying to update my perl cgi script to use SSL when responding to an Instant Payment Notification from PayPal. They provide a test url (tlstest.paypal.com) to test the basic connection to their servers.

Using LWP::UserAgent, I got the following message:

LWP::Protocol::https::Socket: SSL connect attempt failed with unknown error SSL wants a read first at /System/Library/Perl/Extras/5.18/LWP/Protocol/http.pm line 51.

I can easily connect to the host using curl and php, so it isn't a general machine configuration, but it is something specific to perl. Here is the code:

#!/usr/bin/perl
use strict;
use warnings;
use LWP::UserAgent;

my $ua = LWP::UserAgent->new();
$ua->ssl_opts(verify_hostname => 1);
$ua->ssl_opts(SSL_ca_file => './MozillaCAFile.crt');
my $host = 'https://tlstest.paypal.com';
my $req = HTTP::Request->new(GET => "$host");
my $res = $ua->get($host);
if (not $res->is_success) {
  print $res->as_string . "\n";
} else {
  print "Success\n";
  print $res->decoded_content;
}
