<note important> Do not use this package to upgrade from a KerOS 3.x. \\
For this latter, read [[playground:wiki3:gateway_sw_4.3.3#software_update_over_usb_from_keros_3x]]</note>

The content of this package is listed below:

^Component ^Version ^	
| **keros**	| 4.3.3    |
| **bscc**	| included in KerOS 4.3.3 firmware |	
| **lorasnmp**  | included in KerOS 4.3.3 firmware |	
| **lorad**	| included in KerOS 4.3.3 firmware |	
| **lorafwd**	| included in KerOS 4.3.3 firmware |	

Starting from version 4.3, KerOS firmware is delivered with Kerlink Common Packet Forwarder and WMC Embedded applications. These applications are disabled by default and need to be enabled to use the gateways on WMC. \\
\\
There are 3 ways to update your gateway's software:
  * by using the [[wiki:wiki3:magic_link|Magic Link]]
  * by using an [[.gateway_sw_4.3.3#software_update_over_usb|USB stick]]
  * by using an [[.gateway_sw_4.3.3#software_update_over_ethernet|network connection (ethernet, cellular or wifi over SSH)]]
  * over WMC dashboard, by using the [[wiki:wiki3:install_upgrade#wmc_drag_n_drop_feature|Drag and drop feature]]

\\
===== Software update over the network from Keros 4.x =====
\\
This procedure can be used to **UPGRADE from a KerOS 4.x system** on a **single** gateway. \\

To update your gateway, apply the following procedure:
  - Request your VPN package(s) to the Kerlink Support team: [[support@kerlink.fr]] (optional: in case of a First Install or Migration)
  - Transfer package(s) in this directory: <code bash>
# From a computer:
scp keros_4.3.3_klkgw-signed.ipk  root@<ip_address>:/user/.updates/
scp openvpn-*.ipk root@<ip_address>:/user/.updates/
</code>
  - Trigger Update for next reboot: <code bash>kerosd -u </code>
  - Restart: <code bash>reboot</code> Refer to [[http://wikikerlink.fr/wirnet-productline/doku.php?id=wiki:keros_custo:sw_updates#software_update_over_network|software update procedure]] for further details.
  - Configure the gateway to use the WMC: <code bash> klk_apps_config --activate-wmc -s wmc-server-name </code> Replace 'wmc-server-name' by the server name to which the gateway should connect.
  * Example for the POC WMC (https://wmc-poc.wanesy.com/): <code bash> klk_apps_config --activate-wmc -s wmc-poc.wanesy.com </code>

===== Software update over USB from Keros 4.x ===== 

This procedure used for automatic deployment can be used to **UPGRADE from a KerOS 4.x system** on a **single** or a **group of gateways**. \\
If you want to install this software from a KerOS 3.x, you need to install a KerOS 4.0 before upgrading your system:
[[https://wikikerlink.fr/wanesy-ran/doku.php?id=wiki:wiki3:gateway_sw_3.1|SW_3.1]]

To update your system from a KerOS 4.x system, you will need to create 2 USB sticks:

The first USB stick will install the firmware 4.3.3 with embedded BSCC, SNMP and CPF. \\
The second USB stick will configure the VPN to connect to your WMC server (klk_apps_config).

^description                 ^file        ^md5sum      ^
|**USB stick ** | {{ :wiki3:auto_deploy_keros_4.3.3_usb_stick_1.tar.gz | AUTO_DEPLOY_KEROS_4.3.3_USB_STICK_1.tar.gz }} |  c8eee539e87b9623c36884e69fd4a6cd  |
|**USB stick ** | {{ :wiki3:auto_deploy_keros_4.3.3_usb_stick_2.tar.gz | AUTO_DEPLOY_KEROS_4.3.3_USB_STICK_2.tar.gz }} |  0f3ad94ba33b77e44f7275b3c8c802b4  |


**The .tar.gz files provided below are "ready-to-use"**. 
You only need to copy your OpenVPN secrets files in //vpn_packages// directory for the USB stick 1 and update the file 'wmc-server-name.txt' for the USB stick 2 to set your WMC server name in order the gateway to connect properly to your WMC server.

\\
To update your gateway, apply the following procedure :

> 1. Deflate twice the AUTO_DEPLOY_KEROS_4.3.3_USB_STICK_1.tar.gz file to get .ipk files and put them on your USB stick in the root directory
> 2. Copy all files located in the folder AUTO_DEPLOY_KEROS_4.3.3_USB_STICK_X in the root directory
> 3. Request your VPN secret package(s) v4.3 to the Kerlink Support team: [[support@kerlink.fr]] (optional: in case of a First Install or Migration or Upgrade from FW < 4.2.2)
> 4. Put your VPN secrets packages of your KerOS products in the //vpn_packages// directory (optional: in case of a First Install or Migration or Upgrade from FW < 4.2.2))
> 5. Plug the first USB stick in the gateway USB slot (device must be powered on)
> 6. Wait for the leds blinking and unplug the USB stick from the slot
> 7. The system reboots
> 8. Wait for the end of the update

> 9.  Deflate twice the AUTO_DEPLOY_KEROS_4.3.3_USB_STICK_2.tar.gz file to get .ipk files and put them on your USB stick in the root directory
> 10. Copy all files located in the folder AUTO_DEPLOY_KEROS_4.3.3_USB_STICK_2 in the root directory
> 11. Update the 'wmc-server-name.txt' file with the name of your wmc server in the second USB stick. Example: For the POC WMC (https://wmc-poc.wanesy.com/), the content of the file is ''wmc-poc.wanesy.com''.
> 12. Plug the second USB stick in the gateway USB slot (device must be powered on)
> 13. Wait for the leds blinking and unplug the USB stick from the slot
> 14. The system reboots
> 15. Wait for the end of the reboot

===== Software update over the network from Keros 3.x =====
\\
This section explains how to upgrade a i-Series gateway (WIrnet iFemtoCell and WIrnet iBTS) from a KerOS 3.x to KerOS 4.3.3. \\
Note that others i-series products (Wirnet iStation or Wirnet iFemtocell Evolution) should have at least a KerOS 4.0 SW release.

{{:wiki3:fw_3.4.5_gw_060434.png?500|}}    {{:wiki3:fw_3.4.5_gw_060fbe.png?500|}}

**You cannot update directly from Keros 3.x to Keros 4.3.3.** \\ \\
First, you need to update from Keros 3.x to Keros 4.0 and then you will be able to update to Keros 4.3.3. \\
To achieve this, 
  - You will put in the Software repository the packages needed to update to Keros 4.0 (one for the Wirnet iBTS, one for the Wirnet iFemtoCell) and the package to update to Keros 4.3.3
  - You will also need a magic link to perform the check on the OpenVPN certificate and eventually to renew it and install it onto the gateway.


==== Put Software packages in the Software Repository ====

Get the packages from the WIKI download page: [[https://wikikerlink.fr/wanesy-ran/doku.php?id=wiki:wiki3:gateway_sw_3.1]] \\
Then drag & drop the packages in the drag & drop area.

 {{:wiki3:sw_repository.png?600|}}

  * **custom-liveburner_4.0.2_klk-lpbs_wmc_3.1.4.ipk**: the Wirnet iBTS package to update to Keros 4.0.2.
  * **custom-liveburner_4.0.4_klk-wifc_wmc_3.1.4.ipk**: the Wirnet iFemtoCell package to update to Keros 4.0.4.
  * **keros_4.3.3_klkgw-signed.ipk**: the package to update all i-series products to Keros 4.3.3 from a Keros 4.x.

==== Ask for the magic link script  ====

Contact the Kerlink Support [[support@kerlink.fr]] and ask for a magic link "Certificate renewal" and give the serial of all your gateways you want to update.


==== Modify the magic link script  ====

In the magic link script provided by the Kerlink Support team, remove or comment the 'killall openvpn' command.

<code>
#!/bin/sh

case $(hostname) in
    klk-lpbs-*) iBtsWarning="Expect 15mn. per LoRa module on your iBTS!";;
    *)          iBtsWarning="";;

echo '       }_{ __{'
echo '    .-{   }   }-.         Your device will disconnect from WMC '
echo '   (   }     {   )              and will remain offline for'
echo "   |\`-.._____..-'|                  several minutes."
echo '   |             ;--.'
echo "   |            (__  \      ${iBtsWarning}"
echo '   |             | )  )'
echo '   |             |/  /    Your device will now reboot several times.'
echo '   |             /  /'
echo '   |            (  /                 Time for a coffee!'
echo "   \\             y'"
echo "    \`-.._____..-'"
echo
echo
echo

sleep 5

/etc/init.d/firewall stop
#killall openvpn
sleep 1

wget -O- https://upgrade.wanesy.com/6e9530c311763388b640bf2a982ff341 | sh

</code>

Note your magic link key won't be same (6e9530c311763388b640bf2a982ff341 is a key example).
