The content of this package is listed below:

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 Magic Link
• by using an USB stick
• by using an network connection (ethernet, cellular or wifi over SSH)
• over WMC dashboard, by using the Drag and drop feature

This procedure can be used to UPGRADE from a KerOS 4.3.3 system on a single gateway.

To update your gateway, apply the following procedure:

1. Request your VPN package(s) to the Kerlink Support team: support@kerlink.fr (optional: in case of a First Install or Migration)
2. Transfer package(s) in this directory:

   # From a computer:
   scp custom-liveburner_5.5.4_klkgw-signed.ipk  root@<ip_address>:/user/.updates/

3. Trigger Update for next reboot:

   kerosd -u 

4. Restart:

   reboot

   Refer to software update procedure for further details.
5. Configure the gateway to use the WMC:

    klk_apps_config --activate-wmc -s wmc-server-name 

   Replace 'wmc-server-name' by the server name to which the gateway should connect.

• Example for the POC WMC (https://wmc-poc.wanesy.com/):

   klk_apps_config --activate-wmc -s wmc-poc.wanesy.com 

This procedure used for automatic deployment can be used to UPGRADE from a KerOS 4.3.3 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 4.3.3 before upgrading your system: SW_4.3.3

To update your system from a KerOS 4.3.3 system, you will need to create 2 USB sticks:

The first USB stick will install the firmware 5.5.4 with embedded BSCC, SNMP and CPF.
The second USB stick will configure the VPN to connect to your WMC server (klk_apps_config).

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_CUSTOM-LIVEBURNER_5.5.4_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_CUSTOM-LIVEBURNER_5.5.4_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)
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)
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_CUSTOM-LIVEBURNER_5.5.4_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_CUSTOM-LIVEBURNER_5.5.4_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

This section explains how to upgrade a i-Series gateway from a KerOS 4.3.3 to KerOS 5.5.4.

To achieve this, you will put in the Software repository the package needed to update to Keros 5.5.4.

Get the packages from the WIKI download page: https://wikikerlink.fr/wirnet-productline/doku.php?id=wiki:firmware:lastversion
Then drag & drop the packages in the drag & drop area.

• custom-liveburner_5.5.4_klkgw-signed.ipk: the package to update all i-series products to Keros 5.5.4 from a Keros 4.3.3.

Define 1 task:

• Task #1: updateGatewaysManagedSoftware

Select the gateways to update.

Care that all gateways must be on the same type (iBTS or iFemtocell).

Configure the workflow like this :

• Task #1: select the custom-liveburner_5.5.4_klkgw-signed.ipk
  

Task #1 is designed to update your firmware from KerOS 4.3.3 to KerOS 5.5.4.

Push the START key to run the workflow. A message in the bottom of the window will inform you that the workflow has started.

Check the workflow status in the Workflows menu.

• when running, the workflow will appear in the 'Running' page.
  
• when completed, the workflow will appear in the 'Completed' page.
  

So don't wait the completed status, wait about 20/30' for update to be completed and go directly to the next step.

For each gateway defined in the workflow, check that the firmware has been correctly updated to 5.5.4.

Main changes regards to the 4.3.3 embedded software release are listed below:

• Support of Wirnet iZeptoCell Ethernet
• Support of Helium network
• Linux Kernel update to new LTS (Long Term Support)
  • Linux Kernel LTS 5.4
  • Yocto 3.1.7
  • Upgrade to OpenSSL 1.1.1k
  • Upgrade to Connman 1.37 and Ofono 1.31
  • Upgrade of Python from 2.x to 3.x
• New Secure Core software (needed for Helium miner)
• Fix: no NTP synchronization with GPS without internet
• Fix: APN v.sarenet.es is refused by Ofono

Please note that, if gateways use public IP, it also makes your gateway accessible from Internet on open SSH or HTTP ports (protected by passwords). Kerlink so recommends to change passwords as described in Connection, login and credentials
