Port knocking

leave a comment »


Finding information related with dynamic port resolution, I got a very nice knowdledge related with the use of “closed” ports, is it called port knocking. In debian, is as simple as usual:

aptitude install knockd

Is a very simple and cute application of security by obscurity, so it is not really security, but is still nice. And just for the record, port nocking does not work for dynamic port resolution.

A nice reference is here: http://xnoccio.com/?p=25, http://linuca.org/body.phtml?nIdNoticia=275
