testing open ports on the user's side

[Emma Jane Hogbin <emmajane@xtrinsic.com>]

Hi everyone,

I'm working on a web site that includes streamed rich media files. I need
a way to test to see which ports the user can access if they're behind a
firewall. I'm guess that I need to try and send them an object (a picture
maybe?) on one of the ports I need information about and then see if the
picture is received or not.

There must be some kind of script already written that can do this for me
(Perl package, maybe?).

Any suggestions would be appreciated,
emma
