How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

lyoshenka

Intro

The plan is to create a pair of executables (ngrok and ngrokd) that are connected with a self-signed SSL cert. Since the client and server executables are paired, you won't be able to use any other ngrok to connect to this ngrokd, and vice versa.

DNS

Add two DNS records: one for the base domain and one for the wildcard domain. For example, if your base domain is domain.com, you'll need a record for that and for *.domain.com.

Different Operating Systems

Description

mptcp_kernel is the kernel package which built with mptcp (MultiPath TCP) function. The source code is hosted in github .

The RPM package is hosted on Fedora copr. It can be used on Fedora and CentOS (only x86_64) and their some versions..

####WARNING

This package is now still working in progress and being tested by Kenjiro Nakayama. Please don't use it in your production system. And this is not official repository and please take full responsibility for your actions.
