System Configuration 6. Remove any “CB” entries that provide access to individual users from the /etc/password file locally on the ContentBridge and file under /tftpboot/config/gateway on all ContentDirectors. Open /etc/password and delete entries for the same individual users (the entries do not contain “CB” in this file). NOTE: In order to access the MediaGrid, the individual users must be added to the Active Directory domain. 7. Add the following line to the ContentBridge configuration file. This can be done via SystemManager or by editing /tftpboot/config/gateway/ manually on ALL ContentDirectors. NATIVE Replace with the hostname of the ContentBridge. 8. Restart the gateway service: service gateway restart 9. Repeat steps 1-8 for all remaining ContentBridges in the MediaGrid cluster. Verify Communication with the Domain Controller Follow the steps described in Verifying Communication with the Domain Controller. Adding the Omneon MediaGrid Devices to the Local DNS An entry for each of the Omneon MediaGrid devices below must be added to the customer’s DNS for client access of the Omneon MediaGrid system. This will result in the DNS providing a round-robin allocation of the IP addresses when requested. Contact the customer network administrator to complete these procedures. The following entries must be added to the local DNS: • The ContentDirector names as well as the IP addresses of each public interface. • The ContentBridge (if present in the system) name and IP address. • The SystemManager name and IP address. • The Omneon MediaGrid name, which should be associated with the public IP addresses of all the ContentDirectors. This name is distinct from the individual names of the ContentDirectors. The ContentDirectors work together in a manner similar to a cluster. Because of this clustering type of operation, clients can connect to any of the ContentDirectors. In order for this to happen, the customer’s DNS must have the IP addresses of each of the ContentDirectors added (with the same name). These address records (type A) should have a low TTL value (60 second range) due to caching considerations. Note that each ContentDirector has two ports for client access, which means that there will be two address entries in the DNS for each ContentDirector. Since the DNS uses a cyclic round robin allocation technique, the address records should be in the DNS in the following order: 112 Installation and Configuration Guide

The entries above associate an IP address with its host name (forward DNS entry). A reverse entry allows the identification of a host name from an IP address. You can use the nslookup command to find an IP address associated with a host name, for example: $ nslookup contentdirector-3 Server: mediagrid-3.company.local Addresses: 10.30.3.200, 10.30.7.200 Refer to Setting up Reverse DNS Lookups to add reverse DNS entries. Setting up Reverse DNS Lookups Follow these steps to configure reverse DNS entries for Omneon MediaGrid devices on a Microsoft Windows-based DNS server. For other types of DNS servers, consult the appropriate documentation or Network Administrator to set up reverse DNS entries. These instructions are an overview of setting up reverse DNS lookups.
