====== Troubleshooting RADIUSdesk Accel-ppp Agent ======
  * This page will explain some of the working of the RADIUSdesk Accel-ppp Agent as well as some troubleshooting tips.
===== Startup =====
  * The rd.local startup script does three things
        * Configure IP Table rules for NAT.
        * Run the /etc/MESHdesk/u.lua script to fetch the Accel-ppp config from RADIUSdesk.
        * Start the /etc/MESHdesk/heartbat.lua script to start reporting back to RADIUSdesk.

===== u.lua =====
  * You can run u.lua manually to see if it fetches its settings
<code bash>
cd /etc/MESHdesk
sudo ./u.la
E4-5F-01-41-59-70
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  2382    0  2382    0     0  14699      0 --:--:-- --:--:-- --:--:-- 14795
Restarting accel-ppp (via systemctl): accel-ppp.service.
</code>
  * You can confirm that the config was proper formulated and everything is in order with ///etc/accel-ppp.conf//
<code bash>
sudo cat /etc/accel-ppp.conf
</code>  
  * You can also do the Ajax call which u.lua does from a browser to evaluate the JSON data that RADIUSdesk returns.
  * https://cloud.radiusdesk.com/cake4/rd_cake/accel-servers/get-config-for-server.json?mac=64-64-4A-D1-2D-67
  * Use the above URL as reference and replace the FQDN with your server's FQDN or IP Address and also the MAC Addres with your device's MAC Address.
  * The second part that might need troubleshooting is the reporting side.

===== report_to_server.lua =====
  * You can run the reporting script manually:
<code bash>
cd /etc/MESHdesk/reporting
sudo ./report_to_server.lua 
</code>
  * You should should see something like the following in the output:
<code bash>
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  1939    0    39  100  1900    226  11024 --:--:-- --:--:-- --:--:-- 11273
{
    "success": true,
    "data": []
}
Doing the *light* report

</code>
===== Using accel-cmd =====
  * For security reasons we implement a password when using **accel-cmd**.
  * This password is specified on the Profile of a server.
  * You can find the password by looking at the profile on RADIUSdesk's side or by looking at the config file on the device running Accel-ppp.
<code bash>
[cli]
password=testing123
telnet=127.0.0.1:2000
verbose=1
tcp=127.0.0.1:2001
</code>
  * A command will then look like this with the password above.
<code bash>
accel-cmd -P testing123 show stat 
accel-cmd -P testing123 show sessions
