Linux: How to setup as DNS client / name server IP address
Many new Linux user finds it difficult to setup / modify new name server address (NS1 / NS2).
Local name resolution is done via /etc/hosts file. If you have small network then use /etc/hosts file. DNS (domain name service is accountable for associating domain names with ip address, for example domain yahoo.com is easy to remember than IP address 202.66.66.12) provides better name resolution. To configure Linux as DNS client you need to edit or modify /etc/resolv.conf file. This file defines which name servers to use. You want to setup linux to browse net or run network services like www or smtp; then you need to point out to correct ISP DNS servers:
Setup DNS Name resolution
Steps to configure Linux as DNS client, first login as a root user (use su command):
Step # 1: Open /etc/resolv.conf file:
# vi /etc/resolv.conf
Step #2: Add your ISP nameserver as follows:
search isp.com nameserver 202.54.1.110 nameserver 202.54.1.112 nameserver 202.54.1.115
Note Max. three nameserver can be used/defined at a time.
Step # 3:Test setup nslookup or dig command:
$ dig www.nixcraft.com $ nslookup www.nixcraft.com

Very precise brief & 100% helpful
Thanks!!
This is quite useful when you have DSL or dial up connection and would like to setup dns quickly under Linux. Or even when you can’t browse site on net using domain name but you can browse them (ping them) using the ip-address. This solved my problem as well as Temporary failure in name resolution (which can be caused by ssh, telnet or mail client etc) To browse Internet one need to configure the DNS properly. Thanks for this tiny post.

Hi,
I’ve setup the internet connection through PPP dial up and able to get the public IP assigned to me. Also I’ve configured the DNS server address in the /etc/resolv.conf file.
The problem is, I’m able to ping to my ISP’s IP and also to any public IP addresses, but not to any domain names.
ping http://www.google.com, always fails saying unknown host, but at the same time nslookup and dig work fine(able to resove IP from domain name).
What may be the problem?, please do help, Thanks in advance,
–Ganesh
try ping google.com
