Content Gateway does not resolve websites

The browser indicates that it is contacting the host and then times out with the following message:

The document contains no data; Try again later, or contact the server's Administrator....

Make sure that the system is configured correctly and that Content Gateway can read the name resolution file.

• Use the nslookup command to confirm that the server can resolve DNS lookups. For example:

  nslookup www.example.com

• Confirm that /etc/resolv.conf contains the valid IP address of your DNS server(s).
• On some systems, if the /etc/resolv.conf file is unreadable or has no name server entry, the operating system will use localhost as a name server. However, Content Gateway does not use this convention. If you want to use localhost as a name server, you must add a name server entry for 127.0.0.1 or 0.0.0.0 in /etc/ resolv.conf.
