[Chilli] Administrative-User session & config update

[Adam Hammond]

Hi list,

Has anyone succeeded in getting the Administrative-User session functionality fully working?

I have a test AP running an Adminstrative-User session fine (config is returned in Access-Accept and stored in a file). The config is written to non-default file (/tmp/foo) in line with my adminupdatefile setting. The session re-auths every hour and the config is re-written to my adminupdatefile at that time.

If I change the settings returned in radius what DOESN'T happen is these changes being recognised, copied to the chilli config file (hs.conf) and chilli HUP'd. 

This would be trivial to do manually via a script in cron, but it's my understanding that chilli should do this. Am I wrong or is this a bug do you think/know?

I have also not had any luck controlling the interval in which chilli re-auths the administrative-user session. I have tried setting HS_ADMININTERVAL and also returning a Session-Timeout value in the Access-Accept to no avail. Has anyone had any success controlling the session time?

I've included some debug output below for anyone that knows if this looks right or not. It appears that the config is saved in my adminupdatefile location and copied to /tmp/hs.conf rather than /etc/chilli/hs.conf (?)

Possibly relevant: I'm not using a call to writeconfg in my start script. I want to fully control the dns servers over radius. If I use writeconfig the dns1 attribute is set to the devices primary dns server (or one that I hardcode) and this is not overruled if I return a different server ip by radius config. Rather than find a way to patch the functions file I took the easy route of using a static main.conf and fetching the rest of the configuration over radius.

Many thanks in advance,
Adam
