I would no longer recommend port knocking using a static port sequence. Instead, I'd recommend knockknock by moxie, https://github.com/moxie0/knockknock/blob/master/README On 3 May 2016 14:58, "Cristian Consonni" <kikkocristian@gmail.com> wrote:

Hi,

I am putting together a blog post with tips and tools for administrating a node and then I have discovered the technique of "port knocking".

I decided to experiment with it and I have created a guide that puts it together with the default configuration for iptables by torservers/moba[1a][1b].

I have searched on this list and the topic of port knocking has been discussed very rarely (last discussions in late 2014).

This is the guide I have writen: https://balist.es/blog/2016/05/03/configure-port-knocking-for-a-tor-node/

I would like to receive some feedback and I hope this can be useful for other operators.
