I'm sure this is trivial but all the info I've found online has been too vague to help me sort it. If I want a Linux box (Ubuntu/Debian) to have the FQDN of mybox.example.com, where do I set it? I understand that /etc/hostname should contain the "mybox" bit, but where does example.com go? I would expect the following queries and responses hostname -d Should give "example.com", gives "" (empty string) hostname -s Should give "mybox", and does hostname --fqdn Should give "mybox.example.com", gives "mybox" I even managed to get "hostname -s" to return "mybox.example.com" earlier, although I can't now reproduce it. NB: I do know that after changing /etc/hostname I need to run hostname -F /etc/hostname -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG
