Black Box Coalesce WC-COA-I User Manual page 5

For example, the university could add a record to their name server as follows:
Type: A
Name: Coalescedirectoryservice.university.edu
IP: 192.168.1.100
This record is added to the existing zone so that there is no poisoning of the customer's DNS with a "blackbox.com" zone. For
this to work properly, the client operating system needs to automatically append the local domain name when resolving the host
name, so that the DNS can match it to its record.
This can be accomplished by configuring the DHCP server (typically a wired or wireless router) to provide the default domain
name to the client device when it provides the IP address for the device. Devices should then append this domain name to host
names when attempting to resolve the host name to an IP address.
NOTE: Option two does not work correctly on Android devices because the Android OS does not automatically add the domain to
an unqualified name. We expect this to be fixed by Google eventually. In the meantime, please use Option One if you
expect Android clients to connect to your Coalesce installations within your organization. Alternatively, Android devices can
always connect by typing in the IP address of the Coaslesce display host computer.
Both the Coaslesce display software and the Coaslesce client software communicate to the CDS periodically using lightweight
TCP/IP packets over ports 53200 and 53201, which will need to be allowed through the host machine's firewall, as well as on the
network(s). Active displays periodically provide an entry to the CDS that includes their current display name and a corresponding
IP address. Likewise, client devices will receive a list of available displays from CDS at connection time, allowing users to simply
click the display they want to connect to. The corresponding IP address is then used to facilitate connection between the client
and display. Displays and clients will automatically attempt to resolve the IP address of the CDS using both of the above methods.
No special configuration is required.
If CDS is active and correctly routed on the network, Coalesce Central will indicate this by changing the CDS tab logo from dark
grey to bright green. By clicking on the CDS tab, the set of displays that are being added to the CDS and published to client
devices on your network can be viewed. Finally, Solstice displays can be added/removed from the CDS on an individual basis by
checking/unchecking the "Publish Display Name to Coalesce Directory Service" feature under the Configuration and Security tab.
