Dear Sirs! Should the name in /etc/myname include a domain name? Even when I do not have a static IP registered in a public DNS?
In "man 5 myname" I read: "The file should contain a single line specifying the fully qualified domain name (FQDN) of the system" Does FQDN mean, that anyone in the internet must be able to resolve the name? Or only resolvable in my machine? I do not find any restriction in "man 1 hostname". I also read in myname (5):
The name must be resolvable, either by matching a hostname specified in /etc/hosts (see hosts(5)) or through DNS (see resolv.conf(5)).
<< And at the end of "man 5 hosts":
Host names may contain any printable character other than a field delimiter, newline, or comment character." << As I understand, names in /etc/hosts must not necessarily contain a dot (a "domain"). /etc/hosts is not a hierarchical database, the dot is only necessary for the hierarchical DNS database. Thanks, Rodrigo.
