Problem
All DNS (Domain Name Service) clients require the presence of the /etc/nsswitch.conf and /etc/resolv.conf files. Note that the DNS server must also be configured as a DNS Client if it intends to use its own DNS Services.
The /etc/nsswitch.conf file specifies the resolver library routines to be used for resolving hostnames and addresses. Modify the /etc/nsswitch.conf file by editing the hosts entry and adding the dns keyword.
To ensure proper network configuration during the boot process, make sure that the files keyword is listed first. The following example shows a hosts entry configured for DNS.
<snippet from /etc/nsswitch.conf>
hosts: files dns
The /etc/resolv.conf file specifies the Name Servers that the client must use for the Domain, and the search path used for queries.
<snippet from /etc/resolv.conf for DNS clients of the one.edu domain>
search one.edu
nameserver xxx.xxx.xxx.xxx
nameserver xxx.xxx.xxx.xxx
Solution
Verify the status of DNS services. In the following example the DNS client service is running and the DNS server is disabled.
svcs -a | grep dns
