Prerequisites

1. JoKeR's firmware: [FW C009-M Advanced]
2. First access to device after the (successful) firmware upgrade:

... use a telnet client (e.g. Putty) to connect to the device:

box# cd /mnt/C
box# ls

... there should be no sys/ directory at the time

box# wget http://mgb111.pradnik.net/minimal-config.tar
box# tar xvf minimal-config.tar

3. Configuration
Consider following settings in file "/mnt/C/sys/etc/env-ng":

# include /etc/rc.nextgen to startup, if RCNG=0, 
# none of bottom options will work 
#(excluding CHBACKUP, NOTELNET, NOLOGIN!)
RCNG=1
# change root home dir from readonly flash to disk
ROOTDIR=1
# change root shell to bash (if exist)
ROOTSHELL=1
# change users shell to bash (if exist)
USERSHELL=1

# if 1 dropbear sshd will start (must exist, and configured!)
DROPBEAR=1

# if 1 then may use extra shell startup scripts 
# /mnt/C/sys/etc/rc.d/rc.* and different style /mnt/C/sys/etc/start.d/* 
# for links to executables.
RCPLUS=1

# if 1 then kernel module will be unloaded
NOWIFI=1

... and creation of following files:
/mnt/C/sys/etc/rc.d/rc.kill

### kill/remove unused#
killall -9 dhcpd amit_avs amit_tftpd amit_db 2>/dev/null &
route del -net 224.0.0.0 netmask 240.0.0.0 dev br0

/mnt/C/sys/etc/rc.d/rc.cfg

### replace system configs
# hostname mgb111.host.net
# cat /mnt/C/sys/etc/smb.conf > /var/config/samba/smb.conf
# cat /mnt/C/sys/etc/resolv.conf > /etc/resolv.conf
# cat /mnt/C/sys/etc/hosts > /etc/hosts

# place user dirs at /home directory
sed -i 's|/tmp/Virtual/|/home/|g' /var/config/passwd

4. X client-server configuration
We need an X server running and accessible for our X client applications. There are plenty of possible configurations, I use the XMing server. For details see XMing notes and XMing intallation guide.

Download locations: [XMing mesa] [XMing fonts]
Once we install and run the X server we have to configure X clients properly:

box# export DISPLAY=<X-server-host-IP>:0

Now we can try to launch one:

box# /mnt/C/sys/X11/bin/xterm
Xlib: connection to "<X-server-host-IP>:0.0" refused by server
Xlib: No protocol specified
xterm Xt error: Can't open display: <X-server-host-IP>:0

There is a configuration problem. When we look at the XMing log, we see:

AUDIT: ... Xming: client 4 rejected from IP <X-server-host-IP>

As a quick solution, we can disable the access control:
Note: -ac is unsafe on public networks, but makes things easier for beginners on private ones.

C:\Program Files\XMing\Xming.exe :0 -clipboard -multiwindow -ac

... and problem is solved.

To make the DISPLAY and other X related settings permanent we have to add the following lines top the /mnt/C/sys/etc/profile:

# executable library and package paths (both X-based and console apps)
export PATH=$PATH:/mnt/C/sys/X11/bin/
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/mnt/C/sys/lib/:/mnt/C/sys/X11/lib/
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/mnt/C/sys/lib/pkgconfig/:/mnt/C/sys/X11/lib/pkgconfig/
# X server IP (for X-client apps)
export DISPLAY=<X-server-host-IP>:0

Info source: [Public Key Authentication Howto]

box# cd /mnt/C
box# wget http://mgb111.pradnik.net/addons/servers-ssh/dropbear-050.3-n-0.tgz
box# tar xvzf dropbear-050.3-n-0.tgz
box# dropbearkey -t rsa -f /mnt/C/sys/etc/dropbear_rsa_host_key
Will output 1024 bit rsa secret key to '/mnt/C/sys/etc/dropbear_rsa_host_key'
Generating key, this may take a while...
Public key portion is:
ssh-rsa AAAA... <user>@<hostname>
Fingerprint: md5 ... 

... after reboot you can use SSH access (e.g. via Putty with SSH protocol) to connect to the device

Communication with the box

As far as some communication channel can be established (e.g. via TCP/IP in this case) the fact that input/output devices are not present does not matter so much. There is a whole variety of ways how to communicate with such a device.

For example following (mostly client/server) configurations are possible:
(by building X.Org libraries I am just trying to enable the point 3 - I am interested mainly in X client part - not in server part - but do not know the exact dependencies and so I am building all)

1. Web browser as a thin client connecting to a HTTP daemon running on the box (examples: built-in webUI, cvstrac, ...)
2. Telnet/SSH client running on separate machine and connecting to the box with running SSH daemon (example: dropbear + mc)
3. X-client application running on the box and connecting to X-server running elsewhere (e.g. on a PC). Box serves as an application server and X client, PC serves as X server and app client (examples: x applications)
4. VNC viewer connecting to VNC server (along with X server) running on the box (examples: X applications) - not sure it this is possible with Airlive.
5. Some peripherals connected to the box (e.g. via USB). I tried to search the Web and have found some description how to setup USB mouse and keyboard and that there is a USB2SVGA converter and a guide how to set it up. I have no idea what the real possibilities are for the Airlive device and whether it is useful and practical but I think at least in principle it is possible.
