**Setup Xephyr**
 
1. Install Xephyr onto host:
<code class="ruby">
sudo apt-get install xserver-xephyr
</code>

2. Create network device-host through usb0:
2.1 On tizen device switch ssh on:
<code class="ruby">
sdb shell
set_usb_debug.sh --sshon
</code>

//Since turn ssh on you can't use *sdb shell*. You should to turn ssh off if you want to use *sdb shell* by the command://
<code class="ruby">
sdb shell
set_usb_debug.sh --sshoff
</code>

2.2 On host set up usb0 network:
<code class="ruby">
sudo ifconfig usb0 192.168.129.1
</code>

//Check that target device connect like ethernet interface usb0 with IP 192.168.129.1.This interface can disappear form time to time. In this case you can use following bash script://
<code class="ruby">
#!/bin/sh
while true;
do
    sleep 8
    sudo ifconfig usb0 192.168.129.1
done
</code>

3. On client side open terminal and connect to host through ssh with X11 forwarding:
<code class="ruby">
ssh -X login@host_ip
</code>

4. Since you successfully logged in and have been droped to ssh command prompt, you should to run Xephyr in background mode:
<code class="ruby">
Xephyr -ac -br -noreset -screen 800x600 :1 &
</code>


5. Then, you should to connect to device through ssh:
<code class="ruby">
ssh root@192.168.129.3
</code>

6. Great job. Now you can run any Tizen application onto Xephyr, set DISPLAY environment variable before command:
<code class="ruby">
DISPLAY=192.168.129.1:1.0 /usr/apps/org.tizen.message/bin/message
</code>
or
<code class="ruby">
DISPLAY=192.168.129.1:1.0 xclock
</code>
