To ease the upgrade, migration or first installation of gateways, a Magic Link feature can be used. It is a simple command or a simple script based on wget that automatically downloads the required embedded software, configures the VPN connection, configures the packet forwarder with the best default configuration, all in one step.

Request has to be made to customer support through support@kerlink.fr or by opening an OTRS Ticket.

A single Magic Link can be reused for as many gateways as necessary (please include them all when requesting the Magic Link from Kerlink support). It is linked to a single WMC instance.

There is a unique and secret token inside the Magic Link command, Magic Link script or USB package.
This is a secret that shouldn't be shared and transmitted in a non-secure way.

A Magic Link looks like this:

/etc/init.d/firewall stop; killall openvpn; sleep 1; wget -O- https://upgrade.wanesy.com/00112233445566778899aabbccddeeff | sh

It can either be given as is, for copy/paste, or as a ZIP package, for USB installation.

The hash (the 32-digit token in the URL above: 00112233445566778899aabbccddeeff) is secret. Be sure to safely transmit it, and avoid sharing it!

An SSH access to the gateway is required, this means that it shouldn't be already connected to WMC (unless for on-premises servers, in which case SSH is possible from the WMC server itself).

Just copy/paste the provided command and wait for about 5 minutes (20 minutes if Wirnet iBTS with FPGA upgrade).

Unzip the provided package on an USB stick and plug it into the Wirnet gateway.

For Wirnet iBTS and Wirnet iFemtoCell, please remove the USB stick after 15 seconds (as soon as the LED blinks). For Wirnet Station, please leave the USB stick plugged in for 20 minutes, or until the gateway is shown as connected on the WMC instance.

Over WMC dashboard, you can use the Magic Link to update a single gateway or a group of gateways.

For WMC, it is less useful to use the Magic Link as the Software Upgrade feature can be used to send any package: new VPN package (migration), megapackage (upgrade), etc.

The advantage though, is that it's no longer required to download the megapackage from this wiki and upload it in the Software update section of the WMC. The gateway will directly download the megapackage and VPN package through the use of the Magic Link.

Use the File Explorer feature of the WMC to upload the Magic Link script to /tmp or /user. Then use the Remote Shell feature and type: sh /tmp/magic_link.sh

Then execute the Magic Link script using the remote shell feature:

Since the same script can be used to update a gateway, the Magic Link can be used to update a whole set of gateways. That's the magic of this feature !

The first thing to do is to modify the magic link script by adding a random sleep at the beginning of the script in order to delay all the tasks like this:

#!/bin/sh

random=$(shuf -i 1-100 -n 1)
sleep $random

Then, create a template using the 2 following web services:

- CreateGatewayPutFileCommand,
- CreateGatewayCommand.

Take care to put CreateGatewayPutFileCommand as Task #1 and CreateGatewayCommand as Task #2. Give a name to your template and select the button VALIDATE.

Go to your Cart and select your new template:

Click on the CHOOSE A FILE button and select your Magic Link script delivered by the Kerlink Support team:

Set the destination path to /tmp if you are using a WIrnet Station else set the value of /user for KerOS product,

Copy/Paste the Magic Link script filename to the command area and prefixe it with the sh /user/ command:

Select the START button.

Go to the Workflows > Running window to check the execution of the workflow:

Wait a few minutes for the workflow execution to complete.

Due to a bug, for the moment, the end of the workflow is not correctly detected. So you have to check for each gateway in the Configurations > Software page if the update has been correctly done. So, the following page about completed workflows will show information about the completed status of your task ONLY once the time out has been reatched (2 hours):

• over SSH: not applicable for cellular backhaul unless the gateway has a known public IP address. A DHCP server would be necessary on the LAN if Ethernet/WiFi, though static IP should work if directly connected to a computer (static IP and RJ45 cable or WiFi access from the computer to the gateway).
• over USB: works all the time, but requires physical access.

• over SSH: only applicable for on-premises instances (where SSH is available through the VPN tunnel from the WMC server itself).
• using WMC: upload a script and execute it.
• over USB: works all the time, but requires physical access.

• over SSH: only applicable for on-premises instances.
• using WMC: upload a script and execute it.
• over USB: works all the time, but requires physical access.

When may want to upgrade several gateways using the Magic Link. In this case, you can use the workflow feature to achieve this.
