1. Where does it say in the docs that each interface should have an ifconfig file? -> If so, why are you assuming both interfaces should be configured up? 2. What are you trying to accomplish by plugging in both interfaces? 3. Why are you assuming that this should work? dhcpcd probably should not crash but you're probably trying to ask it to do something nonsensical. Andy
