== Arduino Yun and OpenWRT 101 ==

This tutorial covers a little introduction to video recording with on the awesome Arduino Yun board!

I assume that the reader has a pc or a mac (named Bob) and an Arduino Yun, named Arduino. Moreover, I suppose the reader is quite familiar with the computer in general and know a little bit of shell/linux commands. In particular I in my case Bob is a mac os/x and, and everything is starting with an iTerm2 session where everything begin with a dollar sign ($)..

==== Some tricks ====

What I'm using (but not strictly needed if not specified) is iTerm2 as shell terminal on Bob with Oh-My-Zsh as shell, and Sublime Text 2 as a free text/code editor (that is a nice cross-platform generic text editor).

===Let's become confident with the board===

arduino.local does not always resole, so safely to use the ip number (192.168.240.1, for initial configuration) then the host name.

==== SSH from Bob to Arduino ===

To log into the yun via ssh (from Bob shell):

<pre>
$ ssh root@192.168.1.13
</pre>

Now you're logged in the Arduino Yun linux board. We are inside an embedded linux machine, in particular a child of [http://en.wikipedia.org/wiki/OpenWrt OpenWrt].
For briefness I will differentiate what is happening inside the iTerm session in Bob with $ and what is happening inside the yun shell accessed via ssh with ~.

=== Know where we are ===

See which distribution, kernel version, etc:
<pre>
~ cat /proc/version
Linux version 3.8.3 (federico@smilzo) (gcc version 4.6.4 20121210 (prerelease) (Linaro GCC 4.6-2012.12) ) #8 Mon Aug 19 16:22:39 CEST 2013
</pre>

See devices already mounted:
<pre>
mount
</pre>

After each installed package, to see free space on the hard disk:

<pre>
~ df -h
Filesystem Size Used Available Use% Mounted on
rootfs 7.5M 4.9M 2.6M 66% /
/dev/root 7.0M 7.0M 0 100% /rom
tmpfs 29.9M 372.0K 29.5M 1% /tmp
tmpfs 512.0K 0 512.0K 0% /dev
/dev/mtdblock3 7.5M 4.9M 2.6M 66% /overlay
overlayfs:/overlay 7.5M 4.9M 2.6M 66% /
/dev/sda1 7.4G 848.0K 7.4G 0% /mnt/sda1
</pre>

=== Basic networking ===

To run a python server
<pre>
~ python -m SimpleHTTPServer
</pre>

See if python server (or the streaming server, vide infra) is running (from Bob),

<pre>
$ nmap 192.168.1.13

Starting Nmap 6.40 ( http://nmap.org ) at 2014-04-30 13:03 CEST
