Hi,

You miss the trailing dot in the hostname

You are receiving a SERVFAIL error, which indicates that something is wrong with your DNS configuration. The first step would be to look at your log files and see what error messages you are receiving when you try to start/restart your server. What error message(s) are you receiving?

The second thing you can do is use the named-checkconf utility to check your files. See this link for an example.

Also, did you follow any sort of tutorial or information to learn how to setup your files?

mention your domain name after root

@ IN SOA homeserver.homedomain.com. root.yourdomainname (

in both forward and reverse domain

hi
when i start DNS the log file shows this type of output and when i try to resolve using nslookup the given reult is also given below.

Output of log file

chk permission for named file and zone file

If you are running selinux or apparmor you will need to check the permissions there too. Normally you will also have a set of run time zone files, in a place like /var/lib/bind. You will want these to at least be in the bind group, or even owned by bind, so that bind can have write permissions on them. Bind will create a set of database / journal files that it uses to note changes. This is especially important if you try to do any master-slave or dynamic-dns (with DHCP) updates.
