ISPConfig and BIND on Debian sarge (rfc1912 : failed on zonecheck)

[arnaud]

Hello,
I've noticed that on Debian sarge, after configuring dns with ISPConfig web panel, the file /etc/bind/named.conf make an error when testing with zonecheck http://www.zonecheck.fr/
The /etc/bind/named.conf contain initially (from Debian) :
zone "localhost" {
type master;
file "/etc/bind/db.local";
};

zone "127.in-addr.arpa" {
type master;
file "/etc/bind/db.127";
};

zone "0.in-addr.arpa" {
type master;
file "/etc/bind/db.0";
};

zone "255.in-addr.arpa" {
type master;
file "/etc/bind/db.255";
};

And after configuration with ISPConfig, beginning of file looks like this :
zone "." {
type hint;
file "db.root";
};

zone "0.0.127.in-addr.arpa" {
type master;
file "db.local";
};
The problem is on the use of the file "db.local" (/etc/named/db.local) which is the file for zone "localhost" on Debian and the file for zone "0.0.127.in-addr.arpa" (ie : reverse zone) in ISPConfig.
The result is an error when testing with zonecheck and more important : without correction, we can't make some modification in the AFNIC's WHOIS which make use of zonecheck and deny modifications when the test result is not successful.

What's the exact error message you get?
What's in your (ISPConfig) /etc/bind/named.conf?

[arnaud]

Error from http://www.zonecheck.fr/ (name and ip changed)
---- fatal ----
f: Loopback is not resolvable

* Ref: IETF RFC1912 (p.13 4.1. Boot file setup)

These are set up to either provide nameservice for "special" addresses, or to help eliminate accidental queries for broadcast or local address to be sent off to the root nameservers. All of these files will contain NS and SOA records just like the other zone files you maintain.

* site.exemple.net./192.168.0.1 (it'snot the real name/ip)

To remove error from zonecheck.fr, I've commented

// file "db.local";
//};
and add this :
//// MAKE MANUAL ENTRIES BELOW THIS LINE! ////
// be authoritative for the localhost forward and reverse zones, and for
// broadcast zones as per RFC 1912
zone "localhost" {
type master;
file "/etc/bind/db.local";
};

zone "127.in-addr.arpa" {
type master;
file "/etc/bind/db.127";
};

zone "0.in-addr.arpa" {
type master;
file "/etc/bind/db.0";
};

zone "255.in-addr.arpa" {
type master;
file "/etc/bind/db.255";
};

Did you set up Bind as described here? http://www.howtoforge.com/perfect_setup_debian_sarge_p3

[arnaud]

Yes.
The only difference is on some servers the use of
dpkg-reconfigure etherconf
for configuring the network interface.

[falko]

So your Bind is running chrooted now, and you did all these steps?

And did you modify /etc/default/bind9 and /etc/init.d/sysklogd?

What's the output of

ls -la /var/lib/named

?

Looks ok.
