Name Services Used by the Netra Proxy Cache Server

The Netra Proxy Cache Server can use three types of name services:

• DNS: Translation is provided by a DNS server

• Local name service: Translation is done locally (by looking up the name in a file)

• Network Information Service (NIS): Translation is done by an NIS server (running on another host)

The Netra Proxy Cache Server can use any or all of the name services at the same time. If more than one name service is used, they are interrogated in the following order: local name service, NIS, DNS. For example, suppose the Netra server is configured to use the local name service and DNS. When a name service query is made, the server attempts name resolution by looking up the host name in the local database first. If the host name is found, the server returns the host address. If not, the query is passed to the DNS server. If the DNS server resolves the query, it returns the information, otherwise it returns "not found."
