Trick

Check the DNS functionality using the nslookup command
 

In order to check the DNS functionality using the nslookup command

please look at the example and the short explanation.

 

1. from the command prompt write the command:

    [root@eran /root]# nslookup

    You will get a response similar to:

    Default Server: gold.sphera.com

    Address: 172.16.1.231

    Which is the default DNS server of the machine.

2. Then write the command: server [IP of Domain Director]

    > server 172.16.1.84

    The response will be something like:

    Default Server: [172.16.1.84]

    Address: 172.16.1.84

    Now - as we know the Domain Director is the DNS server of the Sphera

    so the VDS's which are located on a Sphera which is connected to the cluster with

    this Domain Director should resolve.

3. Enter a domain name of a VDS which should be resolving you will get something like:

    > eran1.com

    Server: [172.16.1.84]

    Address: 172.16.1.84

    Name: eran1.com

    Address: 172.16.156.20

    Which means that the Domain Director has recognized the domain you have entered,

    and replied with the IP of that VDS.
