[plug] ADSL failover

[Simon Scott]

	Funny, they are getting iinet adsl, but i thought iinet were using
Hel$tra infrastructure? I had bigpong adsl and it sucked the big one.

	Yeh, I think the if-down/up scripts will be the way to go. Or
possibly a seperate daemon that monitors these things and makes sure one or
the other is up.

	Altho Im going to look at Pizzabox and perhaps it has some way for
this to be handled. Even manually would be ok I guess.

	They wont be serving, so it doesnt matter. 

	Thanks

	/etc/network/if-down.d or similar. You can tell pppd to do something

	when it exists. Why not tell it to pick up the modem!

	Evil. Assuming you are calling the same service provider, you can
try and 
	get them to figure this out. You may have to delve into BGP
broadcasts if 
	you have a protable network block, or Dynamic DNS, if you're hosting
services.

	If you're just putting web traffic over it, and not serving stuff
up, 
	then it should matter if you change IP addresses.
