[Chilli] a very common request

[David Bird]

Hi all,

I keep hearing about people wanting to define 'static' ip addresses to
certain computers on their network. I'm experimenting with a feature
that I think will be helpful ... to implement, basically, the equivalent
of the "/etc/ethers" file (though, I don't think it needs to support
hostnames, just MAC address to IP address mappings). 

The way I have it now: on startup and on the --interval, it will read
the file and will basically create a session (or "connection" in chilli)
for each device and the specified IP. The connection will be marked
"reserved" and cannot be removed (due to logout or lease expiration). 

Thoughts? Good? Bad? Make it a compile time option?
