Manually editing<br />

DNS configuration<br />

files<br />

4. To configure the Internet server, do the following:<br />

Manually editing DNS configuration files<br />

a. In the Domain field, verify that the correct domain name appears.<br />

b. In the Authority field, select one <strong>of</strong> the following options:<br />

Master—Select this option if the server you are defining will be a<br />

master name server. A master name server contains name and<br />

address information for every computer within its zone.<br />

Slave—Select this option if the server you are defining will be a<br />

slave name server. A slave name server is similar to a master name<br />

server, except that it does not maintain its own original data.<br />

Instead, it downloads data from another name server.<br />

c. [Conditional] If you selected Slave in the previous step, type the IP<br />

address <strong>of</strong> the master authority server in the Master IP field.<br />

5. Click the Save icon in the toolbar to reconfigure your DNS settings. You<br />

will receive a pop-up message informing you whether the<br />

reconfiguration was successful.<br />

Important: The pop-up message that appears may contain additional<br />

information or warnings about your <strong>Sidewinder</strong> <strong>G2</strong> configuration. Please read this<br />

window carefully before you click OK.<br />

If you prefer to edit the DNS configuration files manually, follow these<br />

steps.<br />

Note: Files with a u extension are for the unbound nameserver, and files with an i<br />

extension are for the Internet nameserver.<br />

Important: You should only edit zone files for a master name server. Never edit the<br />

slave name server files. The file names shown below are for a master name server.<br />

1. Log in to the <strong>Sidewinder</strong> <strong>G2</strong> and enter the following command to<br />

switch to the admin role.<br />

srole<br />

Note: The following two steps assume you have database files named<br />

domain.db and reverse.db in your system. Substitute your file names as<br />

required.<br />

2. Open the /etc/namedb.u/domain.db and /etc/namedb.i/domain.db files<br />

in a UNIX text editor and make the necessary changes.<br />

3. Open the /etc/namedb.u/reverse.db and /etc/namedb.i/reverse.db files in<br />

a UNIX text editor and make the necessary changes.<br />
