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.


	Important If the IP addresses in /etc/resolv.conf change, Content Gateway must be restarted.
