Alias interfaces let you run multiple independent copies of the same network server from the same NIC, and have them be addressed differently, have truly different DNS entries, and all use standard port numbers. I imagine they're a huge win for low-end Web hosting companies, who might put several Web servers/VMs on the same physical box, and oversubscribe the NIC bandwidth reported to their customers. They're wonderfully useful for firewall rules, as well as things like differing QoS classes for different alias interfaces. There're other uses; these are the first that came to my mind. -Deskin Miller -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
