Differences in DNS between freeBSD and Linux:
The forwarding DNS may seem like an unusual option at first - it stores no records, and instead only forwards requests to a series of other DNS servers of which it is aware. In most cases, it is not a terribly useful option. There are a small number of cases, however, where it can be useful, such as where the local DNS server does not support recursion but a remote, forwarding DNS server does - in this case, using the forwarding DNS server can reduce the ammount of traffic across the network.
There are not much different of name server between linux and BSD. Since BIND is an open source package, and linux and BSD are using it. The way to configure name server are the same too. Althought Linux and BSD save config files in different location since they have different file structure.
1. What is the version number of the installed BIND package?
2. What is bind tool called "named-checkconf" use for?
4. What are the names of all the other tools in the bind package?
5. We have used the dig and nslookup bind utilities in this lab, what are the other two bind utilities and what are they for?
Q: What is the purpose of the "host" command ? Give an example of its use.
[root@localhost ~]# host -v ns.lux.on.ca 192.168.2.16
lux.on.ca. 10800 IN SOA ns.lux.on.ca. root.ns.lux.on.ca. 0 86400 3600 604800 10800
