Hello,

I am new to Perl and I'm attempting to interface with Virtuozzo's XML API and seem to be encountering issues establishing a SSL socket -- the SSL handshake is failing.

Error:

Code:
[root@srv perl]# perl wind0ze_api.pl

When I attempt to establish a non-SSL socket it works without an issue.

I have also tested the connection via openssl CLI and it works, so I'm certain it's not related to any packet filtering.

Code:
openssl s_client -debug -connect $IP:4434 -cipher ADH-AES256-SHA
^ WORKS

However, if I omit the '-cipher' option then openssl also will yield a handshake error:

Code:
[root@srv perl]# openssl s_client -debug -connect $IP:4434

P.S. numeric value of $IP omitted for security reasons.

I have also read the IO::Socket:: CPAN pages but it's a lot of information to take in and isn't written in the most user-friendly format. I would appreciate any pointers.
