Exercise 67: Michigan Growers


To restrict all DNS queries to hosts on your network segment, follow these steps:

1.

Log in to the server and start YaST, authenticating as root if prompted.

2.

Choose Network Services and then DNS Server.

NOTE

If DNS is already configured, you can skip to step 6.

3.

At the Forwarder Settings, leave Set Forwarders Manually as the default, configure the other fields, and click Next.

4.

On the DNS Zones dialog, add the zone by clicking Add, and then click Next.

5.

On the Finish Wizard dialog, click Start DNS Server Expert Configuration…

6.

In the left frame, choose Basic Options. This will bring up the display shown in Figure 4.65.

Figure 4.65. Basic options for the DNS server.


7.

Select allow-query in the Option drop-down list.

8.

Type {allowedhosts; } in the Value field and click Add.

9.

Click Finish.

TIP

You can test this configuration easily enough by trying to resolve the lab1.dstechnical.com hostname. If all is working properly, you shouldn't be able to do it.
