Host Names
When you configure the networking parameters of any VCX server, the
script prompts you to assign a host name to the server.
A fully qualified hostname is one that includes the DNS domain name as
the suffix (Example: vcx01.yourdomain.com). The hostname that you
enter when configuring the VCX networking parameters is the
unqualified hostname. In the vcx01.yourdomain.com example, the
unqualified hostname is vcx01.
Use these rules when choosing an unqualified host name:
■
Maximum Length — 11 characters
■
Allowed Characters — Lower case letters, hyphens, and numbers
■
Restrictions
■
A host name must contain at least one alphabetic character.
■
The first and last character in a host name cannot be a hyphen or a
period.
■
Periods are allowed only to separate the fields in a fully qualified
domain name.
Examples:
■
a-5 is a valid unqualified host name but a- and -5 are not.
■
5 is not a valid unqualified host name. It does not contain at least one
alphabetic character.
■
q is a valid unqualified name.
■
aardvark4321 is too long by one character.
■
e.5 is not a valid unqualified host name. The period would indicate
that the host name was e and that 5 was part or all of the domain
name.
