Hi, with the increasing deployment of IPv6 I begin to see an issue icreasingly often: When an interface is configured for IPv6, it takes a few seconds before the IPv6 address actually becomes available. Services that are started in this time window won't listen on IPv6, which may be unintended behavior. Many people see this behavior as a bug in the distribution, which is why I am addressing this issue here on -devel.
Unfortunately, it is non-trivial to find out whether my IPv6 configuration has completed or not. How many addresses will be assigned to us via stateless autoconfig? Are we running with privacy extensions? Do we have additional static configuration? The most "clean" solutions for this issue would be (a) Modify the services to notice when additional IP addresses come up and listen there if the service is configured for that IP address (b) Parse the configuration of each service in the init script and wait for the configured IP addresses to actually come up. Both solutions are rather expensive to implement. Is there a widely accepted method to do things any easier? It is clearly not acceptable to have to manually log in to a newly booted server to restart service, neither do I like the idea of changing runlevels five minutes after reboot to kick IPv6 services to life. Any more ideas? Greetings Marc -- -------------------------------------- !!
