====== Troubleshooting WMC connection issues ======

===== 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 an ''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 Wirnet iBTS or Wirnet iFemtoCell, run the command: ''opkg list-installed'': this will list the installed packages.
    * On Wirnet Station, run the command: ''get_version -u -v'' and check the update log.
    * Check the right OpenVPN package is installed.
    * 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 processes are running:
    * On Wirnet iBTS or Wirnet 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 gateway system indicates a correct date:
    * Run the command ''date''. If the date is incorrect, check the GPS/NTP configuration in ''/etc/ntp.conf''. 
  - Check that the connection to the WMC is working:
    * Check that VPN interface (tun) is up in ''ifconfig''.
    * Check the content of the Trustzone (except for Wirnet Station) ''pnr_uploader -s -b 2'',  ''pnr_uploader -s -b 10''.
    * Check that ''172.17.0.1'' and ''10.8.0.1'' can be ping.
    * Check that ''lns'' and ''snmp'' can be ping.
    * In the dashboard, add the gateway to the customer's fleet and verify that its status is "connected".
        * If the status remains "disconnected" and if your gateway is a Wirnet iBTS then issue the command: ''iptables -L OUTPUT -n |grep "udp spt:10161"''. If this command returns an empty string then issue the command ''/user/snmp/snmpd.init restart'' and wait few seconds. If the problem remains then reboot the gateway.
        * If the status remains "disconnected" and if your gateway is not a Wirnet iBTS then simply reboot the gateway.
  - 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 gateway 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 main logs:
    * **Wirnet iBTS:** 
      * ''/user/spf2/var/log/spf2.log*'' //packet forwarder logs.//\\
      * ''/user/bscc/traces/bscc-*''\\
      * ''/user/snmp/traces/snmp.log*''
    * **Wirnet iFemtoCell:** 
      * ''/user/spf/var/log'' //packet forwarder logs.//\\
      * ''/user/bscc/traces/bscc-*''\\
      * ''/user/snmp/traces/snmp.log*''  
    * **Wirnet Station:** 
      * ''/mnt/fsuser-1/spf/var/log'' //packet forwarder logs.//\\
      * ''/mnt/fsuser-1/bscc/traces/bscc-*''\\
      * ''/mnt/fsuser-1/snmp/traces/snmp.log*''\\
      * ''/mnt/fsuser-1/trace_agent/traceagent-*'' //in case of cellular connection.//\\
  
  * 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 WMC 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.
