If you're running DNS, they should be using that, which will serve an FQDN. If you're not, then /etc/hosts is what will be queried first. ( also, before DNS is running, or if a DNS server can't be reached ) What is an FQDN ? It is the full name of the host machine as it would resolve in DNS. It generally consists of four parts. the fourth part is the hostname of the machine, such as myhost the third part, the lower level domain, such as myhost.example the top level domain in which the example sub-domain exists, such as myhost.example.com and firstly, ( usually left off and assumed by DNS ) the root domain, represented by the blank label after the dot after com. ( because everything is below the root domain, and the standard allows leaving off the domain name *if* the search is confined to within your domain ) In DNS, the FQDN would be myhost.example.com. ( note the trailing dot, followed by the blank label ) As such, that can be one and only one machine anywhere in the universe. The "fully" qualified name can refer to one and only one machine. > # Do not remove the following line, or various programs > # that require network functionality will fail. > 127.0.0.1 localhost.localdomain localhost I wouldn't do that !!

You have host names, but what domain ? The machine should assume whatever domain is in /etc/networks or in /etc/HOSTNAME Generally, the machine won't complain, but some apps will. > also, what is this line for? > ::1 localhost6.localdomain6 localhost6 > it was in there from the default. It's a syntax which some OS understand. Depends on the OS. Remember, Linux is NOT an OS ! Linux is a kernel. Since I don't know your OS ( off hand ) I can't know exactly how your machine will interpret that syntax. Several *nix can use that type of short-hand. -- Cowboy http://cowboy.cwf1.com "I can resist anything but temptation." _______________________________________________ Rivendell-dev mailing list [email protected] http://lists.rivendellaudio.org/mailman/listinfo/rivendell-dev
