Damas Ally
Please,can someone help me on how to configure Secondary dns running in
FC6 with bind-9.3.., bind-chroot-9.3 where by the zone files must be
transfered from primary dns running FC3 with bind-9.2..,
bind-chroot-9.2..I haven't faced any problem to configure in other version
of linux FC5/4/3/2/1 BUT this FC6 become very complicated to me especially
named.conf file in which is normal configuration file for dns...i can't
find the exactly file to edit/configure,i need help from anyone please.

If you're using Fedora 6 you could use system-config-bind utility to
create default named.conf. After that you could add your slave zone to
that configfile. If you're using bind-chroot please run
"bind-chroot-admin --sync". After this procedure you could simply start
named :) (NOTE: if you're using SELinux, please put your slaves zones
into /var/named/slaves directory. You could avoid some problems)

box machine with no graphical user installed so that the
system-config-bind to run,all my settings/configurations are just
terminal/command line,do you have any other idea on how i can get or
create named.conf? minding that i am using bind-chroot.
NB-I'm online skype=damas.ally as well as yahoo messenger=sirgamdam,we can
chat and i can show you all what i have in my machine.

I believe the default chroot directory on FC6 is /var/named/chroot,
so the configuration file is /var/named/chroot/etc/named.conf. (I'm
not running FC6 any longer, but I'm pretty sure that's where it was
when I was...)

thanks for your ideas....sorry for delay happened,i was in field for some
days ....now i am back.
Pls find the sample of my last conf in both master dns and slave dns:-
master dns (fedora core 1, bind 9.2.2, kernel 2.4.22-1.2199.nptlsmp)...the
named.conf file is placed at /var/named/chroot/etc/named.conf,some of the
details are :-
// generated by named-bootconf.pl
options {
directory "/var/named";
/*
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
*/
query-source address * port 53;
notify yes;
};
//
// a caching only nameserver config
//
controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
zone "." IN {
type hint;
file "named.ca";
};
zone "sample.com" IN {
type master;
file "sample.com.zone";
allow-update { none; };
allow-transfer { ip of slave; };
.......
.......
......
zone "x.x.x.in-addr.arpa" IN {
type master;
file "sample.com.rr.zone";
allow-update { none; };
allow-transfer { ip of slave; };
};
include "/etc/rndc.key";
Then,
Slave dns (fedora core 3, bind 9.2.5, kernel 2.6.12-1.1381_FC3smp)
named.conf file is at /var/named/chroot/etc/named.conf ....some of its
details:-
//
// named.conf for Red Hat caching-nameserver
//
options {
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
/*
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
*/
query-source address * port 53;
};
//
// a caching only nameserver config
//
controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
zone "." IN {
type hint;
file "named.ca";
};
zone "sample.com" IN {
type slave;
masters { ip of master; };
file "sample.com.zone";
allow-update { none; };
};
.........
..........
zone "x.x.x.in-addr.arpa" IN {
type slave;
masters { ip of master; };
file "sample.com.rr.zone";
allow-update { none; };
};
With that settings my dns are communicating to each other where by the
master transfer zone files to slave with no prob,
Now,i installed my slave dns with fedora core 6 is where i am getting
confusion with named.conf files as they are about two:-
cmd find / -name named.conf, get the following result
/etc/dbus-1/system.d/named.conf
/usr/share/logwatch/default.conf/services/named.conf
/usr/share/doc/bind-9.3.4/sample/etc/named.conf
/usr/share/system-config-bind/profiles/default/named.conf
The file /usr/share/doc/bind-9.3.4/sample/etc/named.conf and the file
/usr/share/system-config-bind/profiles/default/named.conf one of them is
the file to deal with configuration....can someone help me which one is
the correct file? regarding with the above intro on how my dns used to
work?
regards!

now so it doesn't contains security fixes etc. It's strongly recomended
use Fedora 6 at least (or bind from there) if you want have fixes for
all known CVEs.
logwatch + named cooperation.

/usr/share/system-config-bind/profiles/default/named.conf is used by
system-config-bind (GUI utility for creating named's configuration) to
generate default /etc/named.conf.
/usr/share/doc/bind-9.3.4/sample/etc/named.conf is more advanced sample
of /etc/named.conf. Use info from those files and create your own
/etc/named.conf

i will try to follow up your suggestion but my servers are installed with
no GUI...its only command line, by the way its my idea of running all my
servers with FC6,let me try to create named.conf file from the one you
suggested and back to you.
regards.

There's no named.conf already on the system in FC6. Instead there's
a minimal version called /var/named/chroot/etc/named.caching-nameserver.conf
(or something similar).
I think if /var/named/chroot/etc/named.conf exists and is symlinked to
/etc/named.conf, then that will be used instead when named is run at boot
time.

installed in /etc by default and when you install bind-chroot package
configfiles are symlinked into chroot.
