MESHdesk troubleshooting tips

• These tips might help you troubleshoot the mesh networks you deployed.

• To check if the node is making contact with the back-end you can run a tail -f on the Web server's access log file

tail -f  /var/log/nginx/access.log 

• Here we see one of the nodes contacted the back-end as a gateway

17.8.20.18 - - [17/Aug/2015:04:01:04 -0400] "GET /cake2/rd_cake/nodes/get_config_for_node.json?mac=E8-DE-27-DD-4F-E8&gateway=true HTTP/1.1" 200 6060 "-" "curl/7.38.0"

• You can now use that as reference and query the back-end in the same manner to investigate the reply from the back-end.
• We suppose our server is http://rd01.wificity.asia. The URL will this be: http://rd01.wificity.asia/cake2/rd_cake/nodes/get_config_for_node.json?mac=E8-DE-27-DD-4F-E8&gateway=true
• Here is the return data our server gave the node:

• You should also be able to connect to the gateway node through ssh.
• The gateway node is a DHCP client and you should thus be able to pick it's IP address up from the DHCP server which seed it (Usually a DSL router).
• The username is root and the password is the same as the password that you specify for the mesh under the mesh's common settings (The admin password)
