IPV6 DNS INSTALLATION GUIDE






IPV6 DNS INSTALLATION MANUAL
BIND ON UBNUTU LINUX


This Document will help you to install the IPv6 DNS Server on UBUNTU LINUX. The same method can also be used for the installation on other Linux Flavors . The Software described in the document is bind version 9 . All the Bind 9 and above are supporting IPv6 features.
Bind installation on Ubuntu Linux:
1.    Install the Ubnutu Linux server 12.04 LTS server .
The OS is available on the following website www.ubuntu.com

The Operating system is available for 32 bit or 64 bit Architecture. The Operating System is available under Open Source Platform.

Install  the OS with Std installation features.

2.    The BIND installation

The bind software can be installed on the Server using following commands
            # sudo  apt-get install bind9

3.    After installation assign the IP address i.e. ipv6 Address to the interface.
The file which we need to be edited








This is the file we need to edit for ipv6 address is /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
#START OF IPV6 CONFIGRATION
iface eth0 inet6 static
pre-up modprobe ipv6
address 2001:0db8:0000:0000:0000:0000:0000:0005
netmask 48
gateway 2001:0db8:0000:0000:0000:0000:0000:0001
### END IPV6 configuration
iface eth0 inet static
        address 100.100.100.5
        netmask 255.255.255.0
        network 100.100.100.0
        broadcast 100.100.100.255
        gateway 100.100.100.1
        # dns-* options are implemented by the resolvconf package, if installed
        dns-nameservers 100.100.100.5
        dns-search test.com


the named.conf.options file should contain the following : /etc/bind/named.conf.options
acl v6range {
  2001:DB8::/32;

};
options {
        directory "/var/cache/bind";
        // If there is a firewall between you and nameservers you want
        // to talk to, you may need to fix the firewall to allow multiple
        // ports to talk.  See http://www.kb.cert.org/vuls/id/800113
    
        //========================================================================
        // If BIND logs error messages about the root key being expired,
        // you will need to update your keys.  See https://www.isc.org/bind-keys
        //========================================================================
        dnssec-validation auto;
        allow-query { v6range; };
        auth-nxdomain no;    # conform to RFC1035
        listen-on-v6 { any; };
};


The Resolve.conf file should contain following lines
/etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 2001:DB8::0005;
search test.com
After this we can restart the networking services & named services using following commands
#service bind9 restart.
The nslookup screenshot for the DNS Server is shown below:






Screenshot -1






The PC/Client Desktop needs to be configured using IPv6 DNS Server.





After assigning the IPv6 Address we can browse the following url http://test-ipv6.com to test the IPv6 DNS Server &

IPv6 Traffic.




We can also check the other tab (Summary) in the URL http://test-ipv6.com






Note : If there is firewall between Client and DNS Server allow the port no 53 on UDP and TCP .

sendmail complete cofiguration with pop3 and squirrelmail

Sendmail Introduction Sendmail implements a general purpose internetwork mail routing facility. This document explain how to install sendmail and run an email server which will send and receive mail using the SMTP protocol. An IMAP or POP3 server is required to retrieve mail using Eudora or MS Outlook. Sendmail does not offer POP3 or IMAP services. Installation Prerequisites You should have a basic knowledge of UNIX and DNS. The server should allow incoming connections to the SMTP service which will be listening on TCP port 25. The server should have a fully qualified hostname (FQDN) such as mail.example.net. The hostname should resolve to an A record. It should not be a CNAME. The MX record for the domain for which you wish to receive mail should point to the hostname of your server. There should a PTR record for the IP address of your server. Mail from your server may be rejected if there is no reverse DNS. Installing sendmail Download the sendmail
