Ok, I just skimmed through the source... Alexey's mind is to great to add the wise comments my feeble mind needs :(. I am just emperically trying the settings this time to understand this gc_ stuff... As far as I know being able to handle alternative routes for when the primary route is dead is a host requirement. BTW: I think that hosts should have simple failover controls like this, but routers need and can have better failover controls than this. I posted a rather simplistic nic monitor on linux-ha-dev last week, to monitor a nic's health by arping(using arping ;)) the switch on a private vlan. This way I can have any number of nic's monitored by one daemon. -- <ard@telegraafnet.nl> Telegraaf Elektronische Media http://wwwijzer.nl http://leerquoten.monster.org/ http://www.faqs.org/rfcs/rfc1855.html Let your government know you value your freedom.
