There are 3 ways to do that:

• by using magic link
• by using an USB stick
• by using Ethernet connection (SSH)

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.

To update/connect your system from a KerOS 4.x system, use the following software:

The .tar.gz file provided above is “ready-to-use”. You only need to copy your OpenVPN packages on the USB stick: your OpenVPN secrets files in vpn_packages directory and your OpenVPN config file in the COMMON directory to be able to connect properly to your WMC server.

To update your gateway, apply the following procedure:

1. Unpack the tarball file ('.tar.gz') to get files (README.txt, usb.autorun, …) and put all files on your USB stick in the root directory
2. Request your VPN package(s) to the Kerlink Support team: support@kerlink.fr (optional: in case of a First Install or Migration)
3. Put your VPN config package in the COMMON directory to connect to YOUR WMC server (optional: in case of a First Install or Migration)
4. Put your VPN secrets packages of your KerOS products in the vpn_packages directory (optional: in case of a First Install)
5. Plug the USB stick in the gateway USB slot (device must be powered on)
6. Wait the end of the update (Status led flashes quickly)

Refer to the specific wiki to get more details about software update over USB:

The USB tree should contains the following files/folders:

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:

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 WMC_embedded_keros_v3.3.5.tar.gz openvpn-*.ipk root@<ip_address>:/user/.updates/

3. Deflate archive and ensure file is correctly written:

   # On the gateway:
   cd /user/.updates
   tar -xzf *.tar.gz
   rm -f WMC*.tar.gz
   sync 

4. Trigger Update for next reboot:

   kerosd -u 

5. Restart:

   reboot

Refer to software update procedure for further details.

Here is listed main changelog from v3.2 software release:

• iFemtocell-Evolution gateway support
• Backhaul configuration improvement
• Spectral scan improvement on iStation and iFemtocell-Evolution
• Power management improvement
• Allow Internet access while connected to WMC

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
