Probably only Alexey remembers them correctly (he invented it); I cannot and they're undocumented; so I would suggest everybody to set the interfaces they care about explicitely and use default for new interfaces. > Anyone could offer advice on what the real story is w.r.t. the "all" > and "default" nodes, i.e. what are their exact semantic definitions, > especially in the presence of changing status on interfaces (some web > pages seem to claim that you have to restart the interfaces for these > to take effect, which seems very uncharacteristic of Linux IMO.) For some of them you need to flush the routing cache (echo 0 > /proc/sys/net/ipv4/route/flush) for them to take effect. Restarting interfaces implies that. -Andi - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
