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.

This is a quick set-up guide on how to install Icecast for Mp3 and Ogg streaming, sort of online radio. Tested on Debian Wheezy. Probably works on Ubuntu, etc. Icecast is a "server-like". It offers the HTTP URL/port through which end-users can play the media. However, Icecast itself does not serve the files. It must get its input from other "client-like" software. For example, Ices0 sends mp3 input to Icecast and then Icecast delivers to the end user. Similarly, Ices2 sends ogg input to Icecast and then Icecast delivers to the end user.

Set up icecast

Start by installing:

sudo apt-get install icecast2

To execute any linux command in background we use nohup. But the problem with scp command is that it prompts for the password (if password authentication is used). So to make scp execute as a background process do this:


1>
$ nohup scp file_to_copy user@server:/path/to/copy/the/file > nohup.out 2>&1
if it prompts for password then enter password.
Then press ctrl + z which will temporarily suspend the command, 


SCP will give output:
