2. Configure the following fields as appropriate for your situation.
• Host Name. Enter the host name of this Qube 3. The host name and the
domain name combined together should uniquely identify this server.
Enter only lowercase alphanumeric characters, dashes or periods. For
example, www is a valid entry.
• Domain Name. Enter the domain name of this Qube 3. The host name
and the domain name combined together should uniquely identify this
server. Enter only lowercase alphanumeric characters, dashes or periods.
For example, cobalt.com is a valid entry.
• DNS Servers. Enter the IP address or addresses of your local domain
name server or servers. A domain name server translates textual host
names and domain names into numerical IP addresses, and vice-versa.
Enter a series of four numbers between 0 and 255 separated by periods.
For example, 192.168.1.1 is a valid entry. Leaving this field empty will
prevent this machine from finding other machines by hostname or
domain name and will cause networking difficulties.
