What other platforms support a sensible way of getting IP address change
notifications? (We could certainly get dhcp notification by script in
most Linuxes but that's OS-specific. I suppose if that's the best we
can do I can provide a helper which you can run when your addresses
changed which gathers and sets new addresses)
Thoughts?
Nobody cares? Nobody wants this?
I certainly want this; I carry my laptop around ~everwhere, and it's not
fun when things stop working or become slow because my machine is
advertising an address it hasn't had for weeks, on a network on the other
side of the city.
I haven't looked in much detail, but on Linux it should be possible to get
this sort of notification directly from the network stack, via a netlink
socket. Alternately, most modern distributions are set up to send dbus
events on interface state changes; this is used by the various GUI network
management widgets. Still, this notification is ultimately coming from
dhclient, so we're probably better off getting what we need directly from
the kernel if we can (does anyone know if HAL monitors interface state?)
