ailed while receiving responses: REFUSED on SLAVE with BIND 9.2.2

'chris' — Tue, 09 Sep 2003 20:28:49 GMT

hi

I have 2 intern DNS server BIND 9.2.2
one MASTER ns1 (192.168.0.5)
and one SLAVE (10.41.1.10) running on linux SUSE 8.2
The problem is that MASTER can not transfer to the SLAVE and I get following error all the time:

Sep 9 23:06:41 ns1 named[2636]: transfer of '0.168.192.in-addr.arpa/IN' from 19 2.168.0.5#53: failed while receiving responses: REFUSED
Sep 9 23:06:41 ns1 named[2636]: transfer of '0.168.192.in-addr.arpa/IN' from 19 2.168.0.5#53: end of transfer
Sep 9 23:07:41 ns1 named[2636]: transfer of 'ns2.xxx.de/IN' from 192.168. 0.5#53: failed while receiving responses: REFUSED
Sep 9 23:07:41 ns1 named[2636]: transfer of 'ns2.xxx.de/IN' from 192.168. 0.5#53: end of transfer

MASTER configuration in named.conf:

zone "ns2.xxx.de" {
type master;
file "/var/lib/named/ns2.xxx.de.hosts";
notify yes;
also-notify {
10.41.1.10;
};
};

zone "0.168.192.in-addr.arpa" {
type master;
file "/var/lib/named/192.168.0.rev";
allow-update {
192.168.0.0/24;
127.0.0.1;
};
notify yes;
also-notify {
10.41.1.10;
};
};

SLAVE configuration:

zone " " {
type slave;
file "/var/lib/named/ns2.xxx.de.hosts";
masters {
192.168.0.5;
};
};

zone "0.168.192.in-addr.arpa" {
type slave;
file "/var/lib/named/192.168.0.rev";
masters {
192.168.0.5;
};
};

Know someone, what's wrong ?

Assign points to prior help.

1 for 131 is not so good.

The way this place works is you hand out points for help. I spent 40 minutes digging up scripts for you last night and deserver better treatment.

One hint though. You error mesage can be found in an itrc search.

you need a line in the zone configuration of the master, allowing transfer to the slave

Hi,

Edit named.conf in master servers, under options put...

options {
directory "/var/named";

allow-transfer {
xxx.xxx.xxx.xxx;
yyy.yyy.yyy.yyy;
};

};

where xxx.xxx.xxx.xxx, yyy.yyy.yyy.yyy should be the IP addresses of your slave servers.

Restart named in masters and slaves.

Hi,

Do you have firewalling enabled in your master server using iptables or ipchains.

Log in to the master server.

#netstat -an | grep -i listening | grep 53

Does TCP 53 is in listening state ?.

#iptables -F

OK. Now log in to the slave server.

#telnet xxx.xxx.xxx.xxx 53

where xxx.xxx.xxx.xxx is the ip address of the master server. Do you get connected or you get connection refused ?.

If u get telnet connection to that port. Then its ok. restart named in the slave server. And check again for zone transfer logs.

Please let me know the results.

regards,

U.SivaKumar.

hi U.SivaKumar

the telnet connection (port 53)
to Master and Slave is working well.

at SLAVE:

# netstat -an | grep -i listening | grep 53
unix 2 [ ACC ] STREAM LISTENING 5352 public/flush
unix 2 [ ACC ] STREAM LISTENING 5368 public/showq
unix 2 [ ACC ] STREAM LISTENING 5344 private/bounce

unix 2 [ ACC ] STREAM LISTENING 5384 private/lmtp
unix 2 [ ACC ] STREAM LISTENING 5392 private/maildrop
unix 2 [ ACC ] STREAM LISTENING 5396 private/cyrus

# iptables -F
#

at MASTER:

# netstat -an | grep -i listening | grep 53
#

# iptables -F
#

MASTER is in NOT listening on port TCP 53

the firewalling is not enabled
by MASTER.
I have installed both systems MASTER and
SLAVE by default and I didn't change anything
by iptables.

any idea ?

chris

hi

now I get following error:

Sep 11 20:58:08 ns1 named[1459]: zone 'ns2.xxx.de/IN: refresh: unexpected rcode (REFUSED) from master 192.168.0.5#53

unexpected rcode ?

U.SivaKumar_2 — Fri, 12 Sep 2003 03:26:11 GMT

Hi,

Apologies for my grave mistake.

The command should be.

#netstat -an | grep -i listen | grep 53

Anyway your telnet results shows that named is listening in tcp port 53.

Also in your named.conf of your slave server,

zone " " {
type slave;
file "/var/lib/named/ns2.xxx.de.hosts";
masters {
192.168.0.5;
};
};

Why have you left the zone"" field empty ?. Please put the complete zone name like this.

zone "ns2.xxx.de" {
type slave;
file "/var/lib/named/ns2.xxx.de.hosts";
masters {
192.168.0.5;
};
};

Restart the named in slave server and look for zone transfer logs.

Also please try this.

From the slave server.

#dig @xxx.xxx.xxx.xxx 0.168.192.in-addr.arpa axfr

#dig @xxx.xxx.xxx.xxx ns2.xxx.de axfr

Where xxx.xxx.xxx.xxx is the IP address of your master server.

Does it show complete zone data (zone tranfer)?.

Please let me know the resuls.

regards,

U.SivaKumar

Hi,

I have BIND 9.2.2 in which zone transfers works without any problems without any allow acl statements.

So acl is not your problem. check the ownership and read/write permissions /var/lib/named directory in slave server.

#chown named:named /var/lib/named

#chmod 755 /var/lib/named

restart named in the slave server.

Can you resolve host names in the master server using nslookup ?.

Can you post your permissions of zone files in master server ?.

#ll /var/lib/named

regards,

U.SivaKumar.

hi

I change it, but it doesn't help.

I can resolve host names in the master server using nslookup.

MASTER:

#ll /var/lib/named

drwxr-xr-x 10 named root 4096 Sep 14 15:33 .
drwxr-xr-x 40 root root 4096 Sep 9 22:21 ..

drwxr-xr-x 2 named named 4096 Mar 14 2003 slave
drwxr-xr-x 4 root root 4096 Mar 14 2003 var

I want to say still something.
That was working before and I didn't have any
transfer problems.
The SLAVE server had a total crash and
I did a new setup with the same configuration.
Since does it doesn't work.
I think it have to do with SLAVE

Kind Regards
chris

U.SivaKumar_2 — Mon, 15 Sep 2003 03:16:54 GMT

Hi,

Do this from MASTER.

#dig @127.0.0.1 localhost axfr
#dig @127.0.0.1 ns2.xxx.de axfr
#dig @127.0.0.1 0.168.192.in-addr.arpa axfr

If You cannot see the zone data. Then the problem is with the master server itself. Then download BIND 9.2.2 source from

http://www.isc.org/products/BIND/

and compile the source and install , run the service and try again.

If the above dig methods are successful with the master then you have to look at the slave. Try a fresh compilation and installation of BIND 9.2.2.

please get back with results.

regards,
U.Sivakumar

hi

from MASTER:

# dig @127.0.0.1 localhost axfr

; <<>> DiG 9.2.2 <<>> @127.0.0.1 localhost axfr

from SLAVE:

# dig @127.0.0.1 localhost axfr

; <<>> DiG 9.2.2 <<>> @127.0.0.1 0.168.192.in-addr.arpa axfr
;; global options: printcmd
; Transfer failed.

what I'm NOT understanding.
If I create Slave zone at the SLAVE Server
( I'm doing with webmin ) then I can see
at /var/lib/named 2 empty files:
192.168.0.rev and ns2.xxx.de.hosts
If I restart the BIND these 2 files
will be renamed to:
db-XX2hIJFH and db-XX4gc2To
Both are empty.

perhaps the Master is looking for:
192.168.0.rev and ns2.xxx.de.hosts
at SLAVE and can't find.

chris

U.SivaKumar_2 — Mon, 15 Sep 2003 08:16:39 GMT

Hi,

the problem is with master server itself. otherwise , your dig commands should have done zone transfer successfully.

Don't create files in slave server. As named checks the files for DNS serial number and proper ownership and permission. If it finds a empty file , it renames the file.

Please try this . remove all those notify line and allow-update from master server's named.conf.

notify yes;
also-notify {
10.41.1.10;
};

Restart named. Try dig commands again from the master server itself.

Are you sure that you are using the named.conf file which the named in master server is reading when starting up or is it reading named.conf in someother location ?.

please get back with results. Also please try compiling and installing BIND 9.2.2 in master again.

regards,

U.SivaKumar.
