It's a very simple script, it continuosly greps /var/log/syslog looking for DHCPREQUEST/DHCPACK lines.
When finding one of those it tries to find out if it's a new device (not already added and not one of the ignored). Then it sends DCE Event #53(New Mac Address Detected) with params #5(MAC) and #28(IP) to DCERouter.
As far as I know then it's processed somewhere in General_Info_Plugin (asking for device type, room and other such stuff), after that it creates device with status set to **RUN_CONFIG**.
After that somebody else will run the configuration script specified in DeviceTemplate. Something like:
/usr/pluto/bin/configure_snom3xx.pl -d 47-i 192.168.80.253 -m 00:04:13:24:25:e9
That script is responsable to correctly configure Snom320, so it could be used almost imediatly.
New p&p devices
For each device that needs to be plug&play device we need to:
- create a device template
- add a mac range in device template to include such devices
- create a script that will be called as described above that will configure the device to be used with pluto
Possible problems
- Two or more models (whith very different configurations) of same manufacturer share same IP range
- Now it's solved by asking the user what kind of device he plugged.
- Same model may have different firmwares, meaning that sometimes the configuration script may fail.
- This can't be solved right now. Usually firmware is not distributable, so you can't force to use a specific version with pluto. The firmware upgrade needs user interaction and is very delicate operation that may result in trashed equipment (for example power outage in the middle of upgrade)
