Hello, Feel Free to redirect if -hackers isn't the most appropriate list. I'll soon get a DSL line for Internet connectivity but as stated in the following papers (Thanks to Ted Mittlestaedt), DSL hasn't been designed as a fully reliable media. http://www.computerbits.com/archive/2001/0200/network0102.html http://www.computerbits.com/archive/2001/0300/middlestaedt0103.html Ted shows a way to add reliability by backing up DSL line via ppp(8) http://www.computerbits.com/archive/2001/0400/mittelstaedt0104.html http://www.computerbits.com/archive/2001/0500/mittelstaedt0501.html The exposed method has one major drawback, the need for the isp to create a special configuration for your use and I don't know if the isp we've chosen will do that. Another one is more specific to France where most of the usual DSL ethernet TAs only support pppoe, thus making ppp(8) mandatory for the DSL connectivity. So you do not have any arp entry for the address the isp assigned to you. How is it possible in this case to detect DSL line failure and then change default route to use the backup ppp(8) dialup configuration ? Any idea ? It would be nice to see this kind of setup handled by ppp(8) via a new keyword like <backup> which parameter would be the configuration to use for backup.
