Hi All,
Feeling inquisitive about the options --dhcp-luascript, script-arp,
and script-on-renewal, I've been exploring what possibilities this
brings. Knowing absolutely nothing about lua, I have pulled together a
simple logging script that works -- but I've run up against a problem
in accessing the stored variables. Therefore, this is probably more of
a query about lua than it is about dnsmasq.
The man page states that the environment inherits a number of
variables (example: DNSMASQ_TAGS) which I am trying to retrieve -- but
my current approach is returning nil (eg. tags =
os.getenv("DNSMASQ_TAGS"))
Questions:
* How can I retrieve the contents of the DNSMASQ_ variables (if set)
* Does the dnsmasq log the return status if there is an error?
* and (tentatively / hypothetically), could the actions taken by
dnsmasq in granting/renewing a lease be modified following the results
of running the lua script? For example, if the lua script modified the
DNSMASQ_TAGS variable.
Note: This is NOT a feature request -- purely thinking about what
might be possible...
I've uploaded my current test script to:
https://github.com/whitepj/dnsmasq-lua if this makes anything clearer.
Many thanks,
Phil
