[isf-wifidog] rogue gateways?

See it, been there.

I deleted the default node in the db, and created a 'test node' so the
default will never work.

I ran across this when I was helping a startup community group, and they
were installing and setting up their hotspots, we were hosting their
authentication on our server with a different network ID.

Needless to say once they had their own auth-server up, I was still seeing
their new nodes showing up periodically in the default, sometimes for days
at a time, I needed to do something and deleting the default, and creating
a test was the simple answer.  You are supposed to go into the node to set
it up anyways so using a default seemed a bit too easy.

Sice then I have rolled our own wifidog for OpenWRT, with our default test
node setup and all the appropriate settings (needed a default in case of a
reset, or if we needed to do a full reset remotely, and then go into it
and reconfigure as needed)
and yes the password is also pre-set in this package so we can get into it
to manage it from a reset...

Just my 2 cents
