True timeout on LWP::UserAgent request method
I am trying to implement a request to an unreliable server. The request is a nice to have, but not 100% required for my perl script to successfully complete.

How can I get LWP to validate SSL server certificates?
How can I get LWP to verify that the certificate of the server I'm connecting to is signed by a trusted authority and issued to the correct host?

How can I limit execution time for a Perl script in IIS?

Which of these scripting languages is more appropriate for pen-testing?
First of all, I want to avoid a flame-war on languages. The languages to choose from are Perl, Python and Ruby . I want to mention that I'm confortable with all of them, but the problem is that I can't focus just on one. If for example , I see a cool Perl module, I have to try it out. If I see a nice Python app, I have to know how it's...

In the middle of a Perl script, there is a system command I want to execute.

How do I use transactions with Stomp and ActiveMQ (and Perl)?
I'm trying to replace some bespoke message queues with ActiveMQ, and I need to talk to them (a lot) from Perl. ActiveMQ provides a Stomp interface and Perl has Net::Stomp, so this seems like it should be fine, but it's not. Even if I send a BEGIN command over Stomp, messages sent with SEND are immediately published, and if I ABORT the ...
