Hi,
I am looking for pointers (and if possible example scripts) about a way to create a general TCP/UDP tunneling application over HTTP.
Since I am a beginner in the field I would welcome anything you can tell me about this. I searched PM and the web about this, but the only examples I found were either UDP or TCP tunneling, and not over HTTP (but TCP).
And to rephrase myself, what I am looking for is a general way of having a client program connect to localhost:someport instead of someoutsidehost:someotherport and have all the communications and data transfers between them be transparent for the client (the client actually "thinking" it is connected directly to someoutsidehost:someotherport).
And to make a long story short, I am looking for an incredibly general and powerful way of piercing firewalls using a remote gateway server running some kind of customized HTTP server...
Does that imply using the packet injection module from CPAN on the remote gateway?
I have also seen and tested SOCKS servers, but this kind of application requires the client to be rewritten (if it does not support proxying in its config). So this is *not* interesting to me.
Thanks for helping!
