====== Troubleshooting ======

===== System Overview =====

The RAN as a whole is structured as follows:

  * In the gateway:
    * The packet forwarder receives LoRa frames and forwards them to the lns server which address is usually ''172.18.0.1'' using UDP port 1700
    * There is a ''bscc'' daemon that will be interfaced with the RAN BSC component
    * There is a ''snmp'' daemon that will be interfaced with the RAN
    * There is an OpenVPN package that will handle the secure connection to the RAN
  * In the RAN:
    * The BSC will handle the gateway system management (software, remote shell, system status, etc)
    * The RNC will handle the radio management (spectral scan, frequency planning, etc)
    * The LNS will handle the LoRaWAN data (RX/TX)

===== Process Flow =====

To analyze your potential issues, it is best to go from bottom to top and check every layer:

  - Check basic network
    * if Ethernet, ensure that the link is up, a valid IP is set on eth0 interface (either manually or through DHCP)
    * if WiFi, ensure that the SSID is properly connected and that a valid IP is configured on wlan0 interface (either manually or through DHCP)
    * if cellular, ensure that the APN is properly configured, that the cell signal is good and that there is an IP defined on ppp0 interface
    * Anyway, issue a ''ifconfig'' command to check all interfaces status, and try to ping a machine on the Internet (e.g. 8.8.8.8)
  - Check installed software and version numbers
    * On iBTS or iFemtoCell, run the command: ''ipkg list-installed'': this will list the installed packages
    * On Wirnet Station, run the command: ''get_version -u -v'' and check the update log
    * Anyway, please check that the ''bscc'', ''snmp'', ''openvpn'' and the ''packet forwarder'' packages are correctly installed with the expected version number
  - Check that all expected process are running
    * On iBTS or iFemtoCell, run the command: ''monit status''
    * On all systems, run the command: ''ps ww''
    * Anyway, please ensure that the ''bscc'', ''snmp'', ''openvpn'' and the ''packet forwarder'' processes are running
  - Check that the connection to the RAN is working
    * Check that you have VPN interface in ''ifconfig''
    * Check the content of the Trustzone (except for Wirnet Station) ''pnr_uploader -s -b 2'',  ''pnr_uploader -s -b 10''
    * Check that you can ping ''172.18.0.1'' and ''10.8.0.1''
    * Check that you can ping ''lns'' and ''snmp''
    * Add the station to the customer fleet and verify that the status is "connected"
  - Check that the packet forwarder is working properly
    * Check the configuration of the packet forwarder in the json config file ("lns" should be defined as the server and port 1700 should be used)
    * Check in the dashboard interface that the station has received some messages (be sure that at least one end-device is located in the neighborhood of the gateway)


===== Logs to check =====

  * Check main system logs at ''/var/log/messages''
  * Check packet forwarder logs at ''/user/spf2/var/log/'' for iBTS, ''/user/spf/var/log'' for iFemtoCell and ''/mnt/fsuser-1/spf'' for Wirnet Station
  * Check the kernel boot log with the ''dmesg'' command

===== Ask for support =====

If you couldn't find why your station is not visible on the RAN dashboard or why you can't receive/send LoRa frames, please contact the support:

  * [[http://otrs.kerlinkm2mtechnologies.com/customer.pl]] and open a ticket
  * [[mailto:support@kerlink.fr|support@kerlink.fr]] if you don't have an OTRS account yet

Anyway, please provide information about your product and your issue:
  * serial number
  * product version
  * logs
  * desired behavior / expected result
  * list of checks that you already did

These items can be collected by following the [[#Process Flow]] step.
