My current scenario is this, I have a Windows 2003 Small Business Server and Linux fedora 10 proxy server that is used for internet. On Windows 2003 SBS as a mail exchange. Now need to move away from windows completely to Linux fedora 10. I need to configure a DNS so that i can use the fedora to download email from my ISP to their respectively clients computers.I do not want to host email but still want my ISP to handle the mails and my website. In other words i want to have the same function that is being done by windows to be done by Linux. I have read a some of how tos:http://www.linuxhomenetworking.com/w...onfiguring_DNS, but still confuse

How do i configure the DNS and the mail server on my server without disturbing the ISP settings. On my linux server is connected direct to the router that point to the ISP with eth1 192.168.0.1 and eth2 10.0.0.5 for LAN.
[root@perfecpol7 ~]# host www.perfectpol7.com
www.perfectpol7.com is an alias for perfectpol7.com
perfectpol7.com has address 4a.20a.1a8.1x
perfectpol7.com mail is handled by 5 fw2a.perfectpol7.com.
perfectpol7.com mail is handled by 5 fw1a.perfectpol7.com.

my file is this:
/etc/named.conf//
// named.conf
//
// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
// server as a caching only nameserver (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//

options {
listen-on port 53 { 127.0.0.1; };
listen-on-v6 port 53 { ::1; };
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
memstatistics-file "/var/named/data/named_mem_stats.txt";
allow-query { localhost; };
recursion yes;
};

logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};

zone "." IN {
type hint;
file "named.ca";
};

include "/etc/named.rfc1912.zones";

zone "5.0.0.10.in-addr.arpa" {
type master;
file "/var/named/10.0.0.5.rev";
};

my vi /etc/resolv.conf
# Generated by NetworkManager
nameserver 196.25.1.11
nameserver 196.43.1.11

please assist in setting up a DNS server so that can set up a mail server for the LAN. Not sure the information I have provided will be of help or did I make myself clear about my situation.

I'm honestly not exactly sure what you're trying to accomplish. Try to break down your requirements to a list of specific items.

I want to configure a DNS server and then later a mail server

From the sounds of it, this is a serious setup ie for business, in which case, use Centos not Fedora, as there is a rapid turnover in Fedora versions and its a bleeding edge distro.
Centos is the free version of Redhat, which is the 'stable' version of Fedora.

I need fedora then when acquire the knowledge and skill then I will move to your recommendation, thanks

Running Fedora on a server is a "Bad Idea"(tm).

You are only allowing "Allow Query" from localhost. Also, make sure you have iptables rules allowing lookups:

If your internal network, for example, is 10.10.10.0/24, run this on the fedora box as root:

iptables -I INPUT -p udp -s 10.10.10.0/24 --dport 53 -j ACCEPT
iptables -I OUTPUT -p udp -d 10.10.10.0/24 --sport 53 -j ACCEPT
/etc/init.d/iptables save

You will have to do the same for tcp if you plan on allowing Zone transfers. Oh yea, DNS is one of them magical tcp/udp services.

Anywho, Set your allow-query to either your internal subnet as well as localhost, or just rely on your iptables rules and set it to any.

The following article looks pretty in depth: http://www.linuxhomenetworking.com/w...onfiguring_DNS. You might want to try looking that one up.
