What this article shares with you is about the forwarding mechanism of bind9 domain name server. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it.

Bind9 has been configured recently. It is found that the transponder fowarder mechanism of bind9 always has no effect. The configuration details are as follows:

1. The ubuntu14.04 server version of the operating system for two virtual machines, host1 and host2,host1 and host2, is established in virtualbox.

two。 Install bind9 on both host1 and host2.

3. Configure the domain name zql.com on host1. The domain name was resolved successfully by using the nslookup tool on host1.

4. Configure the domain name zyt.com on host2. The domain name was resolved successfully by using the nslookup tool on host2.

5. The network mode for configuring virtual machines host1 and host2 is Internal, and the static IP for host1 is 192.168.56.2 and the static IP for hsot2 is 192.168.56.4. Ping each other to verify the network connectivity of the two.

6. Configure the respective domain name servers of host1 and host2 as their native IP. Modify the / etc/resolv.conf file of the host1 virtual host, add nameserver192.168.56.2; to modify the / etc/resolv.con file of the host2 virtual host, and add nameserver192.168.56.4.

7. The forwarder forwarder for configuring bind9 for host1 is IP for host2.

8. Configure the log logging in the bind9 of host2.

9. Verify the transponder. Use the nslookup tool to request the domain name zyt.com on host1. Reply to server cannot find zql.com:SERVFAIL. Failed.

10. Analyze the log. Check the log of bind9 on host2 and find that there is a query request from the client 192.168.56.2 at the corresponding time, and the query content is zyt.com.

The above is what the forwarding mechanism of bind9 domain name server is, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
