This is the same as when pinging 192.168.0.255. Check your firewalling rulesets, perhaps? IP aliases in BSD are defined as follows: - a.b.c.d/255.255.255.255 if there is one "main" address in the same network (which will respond to broadcasts) - a.b.c.d/255.255.255.0 (or something else) if there are no other addresses in the same network In Linux, all aliases can be defined as below and they "just work". -- Pekka Savola "Tell me of difficulties surmounted, Netcore Oy not those you stumble over and fall" Systems.
