Dear list, I have a router which automatically identifies the devices connected to it by their host name (its a FritzBox if that matters). However, this does not work for all my arch-boxes. Thus, I get the feeling, I am missing something in my network configuration. Usually, I edit /etc/hostname by putting just the hostname in there. There is also the tool hostnamectl set-hostname myhostname which does the same. The arch wiki says, that the file also may contain the domain, if any. How do I set a hostname with domain? Is it just hostnamectl set-hostname myhostname.domain Then, the arch wiki says, that it is a good idea to add the hostname as alias for localhost in /etc/hosts. Do you do that? And last, which piece of information determines the computers name in the network. Is it the hostname in /etc/hostname, or more likely the aliases in /etc/hosts? Is there anything more I should configure? Thank, Wolfgang
