I have configured linux server as local dns server (practice level).
I have given the IP and hostname details in /etc/hosts
Code:
-bash-3.00# cat /etc/hosts
#
# Internet host table
#
::1 localhost
127.0.0.1 localhost
192.168.1.78 dummy.set.com loghost
192.168.1.57 cent.set.com # dns server
192.168.1.67 next.set.com
-bash-3.00# grep hosts /etc/nsswitch.conf
# DNS for hosts lookups, otherwise it does not use any other naming service.
# “hosts:” and “services:” in this file are used only if the
hosts: files dns
# before searching the hosts databases.
I have given following entries in solaris client /etc/resolv.conf
-bash-3.00# cat /etc/resolv.conf
search set.com
nameserver 192.168.1.57
-bash-3.00# svcs -a | grep dns
disabled 8:38:39 svc:/network/dns/server:default
online 8:39:14 svc:/network/dns/client:default
-bash-3.00# nslookup dummy.set.com
Server: 192.168.1.57
Address: 192.168.1.57#53
** server can’t find dummy.set.com.set.com: REFUSED

The Linux resolver queries all nameservers in the order they are listed in /etc/resolver.conf.
If a nameserver times out, it advances on to the following nameserver.
But, if a nameserver returns "not found" (NXDOMAIN) it stops.
This behaviour is problematic when you need to resolve names from... (0 Replies)

SYNOPSIS
unbound-streamtcp [-unsh] [-f ipaddr[@port]] name type class
DESCRIPTION
unbound-streamtcp sends a DNS Query of the given type and class for the given name to the DNS server over TCP and displays the response.
If the server to query is not given using the -f option then localhost (127.0.0.1) is used. More queries can be given on one commandline,

class Specify the class to lookup for.
-u Use UDP instead of TCP. No retries are attempted.
-n Do not wait for the answer.
-s Use SSL.
-h Print program usage.
-f ipaddr[@port]
Specify the server to send the queries to. If not specified localhost (127.0.0.1) is used.

$ unbound-streamtcp -f 192.168.1.1 www.example.com SOA IN
$ unbound-streamtcp -f 192.168.1.1@1234 153.1.168.192.in-addr.arpa. PTR IN
