Hi Guys.
I installed BIND 9.3.3rc2 straight off the CentOS 5.1 CDs.
By default the /var/named/chroot is empty, so all I did was copy the
cp -R /usr/share/doc/bind-9.3.3/sample/* /var/named/chroot/
and it inserts a working set of files.
Editing /var/named/chroot/etc/named.conf shows a sample setup that listens on all interfaces
(which is why I set up the firewall first to block all interfaces) and has 3 views (localhost_resolver, internal and external)
Then it is a simple matter to set up forwarders in the options section for caching and off you go.
Further tweaking should allow you to restrict the interfaces and adding zones (master/slave/forward) into the appropriate views
will allow resolving of internal or domains hosted by the server.
By default there is no "listen-on port" option in the sample file, so it listens on the default port (53) on all interfaces.
HTH

Andrew.

Hello all,
I´ve installed a proxy Squid in my gateway and a Cache DNS Server with
bind. The problem is the server is only resolving is own querys but not
the client queries from my company.
When I do:
$service named start
I see in /var/log/messages:
starting BIND 9.3.4-P1 -u named -t /var/named/chroot

I don´t understand why is only "listening on IPv4 interface lo,
127.0.0.1#53"
I have bind-chroot installed with the following options in /etc/named.conf:
options {
listen-on port 53 { 127.0.0.1; 10.10.80.0; };
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";
// Those options should be used carefully because they disable port
// randomization
// query-source port 53;
// query-source-v6 port 53;
allow-query { localhost; };
};
logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
view localhost_resolver {
match-clients { localhost; };
match-destinations { localhost; };
recursion yes;
include "/etc/named.rfc1912.zones";
};
Where 10.10.80.0 is my network range. What may I do my server really
listen for all my network? Nowadays it´s listenning just itself ....
Thanks very much for your attention.
