Hi, folks! i am currently trying to improve the whitelisting functionality in HIPL a little bit. Improvement means here to make the whitelisting more sensible for all kind of interfaces. Right now it is only posible to whitelist physical interfaces with all alias-interfaces, which belong to this. So you have no chance to whitelist just a single alias-interface or maybe only the physical interface. My problem is, that at the moment the interfaces will be recognized by an index, which is provided by netlink. The problem with this index is, that it is equal for the physical interface and its alias-interfaces. So my question is: Has anybody an idea, which other unique indicator(except the index) i can use to distinguish between all inerfaces, so that i can whitelist the interfaces in a more conrete way. Example: Machine with the following interfaces: eth0 eth0:0 eth1 eth1:0 eth1:1 At the moment a -hipl -i eth0 -i eth1 would effect that all interfaces are whitelisted, also the alias-interfaces. What i want is, that only the interfaces eth0 and eth1 are whitelisted or maybe a -hipl -i eth1:1 should only whitelist this single alias-interface. Thanks for you help Christian
