DNS Server Setup

Primary DNS (PDNS) Setup:

# rpm –qa|grep bind [to check package]

# rpm –qa|grep caching [to check package]

# cd /var/named [contains 3 setup files (cd /var/named/chroot/var/named for fedora core) ]

1. localhost.zone [Forword lookup zone, converts domain into IP]

2. named.ca [cash memory]

3. named.local [Backword lookup zone, converts IP into domain ]

Example:

To make a PDNS, domain_name: example.com & IP-192.168.1.205, host_name: linux205

# cd /var/named

# cp localhost.zone example.com

# cp named.local 192.168.1.205

# vi example.com

Line 2: ORIGIN example.com

3: linux205.example.com. root.example.com.

10: linux205.example.com

11: 192.168.1.205

12: linux205 IN A 192.168.1.205

# vi 192.168.1.205

Line 2: @ linux205.example.com root.example.com.

8: linux205.example.com.

9: IN A 192.168.1.205

10: 205 IN PTR linux205.example.com.

# vi /etc/named.conf [at first copy the portion localhost.zone & named.local then make change to this]

# vi /etc/resolv.conf [to setup domain IP]

Line 1: nameserver 192.168.1.205

2: search example.com

# service named restart

# rndc reload

Verify Command:

# dig -x 192.168.1.205

# host example.com
