Configuring Subdomains in Hostnames (CTPView Server Menu)

Until CTPView Release 7.1R1, when you enter valid fully qualified domain names (FQDN) with subdomains, CTPView does not enable the subdomains (labels or dots) to be entered and has restrictions with the maximum length of the hostname length to be 24 characters. Starting with CTPView Release 7.2R1, you can specify hostnames of CTP devices (when you select 2) System Configuration from the CLI menu on the CTPView server and select the Change Hostname/Domain menu option to make the changes and to enter the hostname) in compliance with the domain name system (DNS) standards, which enables you to enter labels or subdomains in a hostname. Each label in a hostname can have a maximum of 63 characters and the entire FQDN can be up to a maximum of 253 characters. No specific restriction on the number of labels exists.

To enter the hostnames with subdomains and in accordance with the DNS standards:

  1. From the CTPView Configuration Menu, select 2) System Configuration to select the system settings to configure.
  2. Select the Change Hostname/Domain menu option to make the changes to the hostname and to enter the hostname with subdomains. Each label in a hostname can have a maximum of 63 characters and the entire FQDN can be up to a maximum of 253 characters. No specific restriction on the number of labels exists.
