[Development] Fwd: Fonera 2.1 firmware : service dyndns

[John Crispin]

ok, here goes... 

fonstated basically takes events as an input 

to queue and event do fs -l <EVENT> 

fonstated processes 1 event at a time 

event map directly to /etc/fonstated/ 

currently use a shell script, but it will support lua in the final version 

next, look in /usr/lib/fonstate/*.so these are all plugins running inside or forked by fonstated (hence several processes) 

a fonstated plugin is written in c and can 
* use the internal timer apis 
* queue evente 
* register events 
* the watchdog is controlled via "fs -l" without the need for a script in /etc/fonstated 


there are 2 special events Online and Offline 

these are triggered by fonstate_online.so 

so the idea is that do write a plugin, you need 
* a uci file (the confgi files used by openwrt, really simple) 
* a uvl file (optional) (validation scheme for uci file) 
* luci pages - to configure your daemon, app, ... 
* fonstated script, that handles how, when, where, ... the plugin does something or not 

that was the very quick howto :) more to come when i am ready

Hi, 

Could you also tell us more about this Fon State Daemon? 
How can we control the times a certain service is run; and what it is running(shellscript outside of the code or is it inside the fon state daemon sourcecode?) 
...so we can adapt the script and add checks&other dynamic dns services for instance

you can replace stuff, that is the idea. if the changes are cool, they will make their way into the main tree.

Question: 
* Can the community write a plugin to "replace" existing(but limited) functionality? or will it be shown a "services -> Fon Dyndns" AND "plugin -> Community DynDns"; where the latter will work even if the Fonera is NOT connected directly to the internet? (Duality) 

Thnx, 
Steven
