Problem with slave DNS

I have an ISPConfig perfect setup on Debian 3.1 and i have a problem with slave DNS. When i create a slave zone on my ISPCONFIG, i have this error in my syslog file :

Code:

Jan  3 18:19:15 jedi named[15319]: transfer of 'domain.org/IN' from 195 ... ... ...#53: failed while receiving responses: REFUSED
Jan  3 18:19:15 jedi named[15319]: transfer of 'domain.org/IN' from 195 ... ... ...#53: end of transfer

My named.conf seems to be good but the zone file isn't created. It seems to be a problem with a chmod on a directory...?

/var/lib/named = 755 root:root

/var/lib/named/etc = 755 root:root

/var/lib/named/etc/bind = 755 bind:bind


On my primary DNS server i have this in my named.conf :

Code:

zone "domain.org" {
         type master;
         file "domain.zone";
         allow-transfer {195 ... ... ...; };
};

My primary DNS server is not an IPSconfig server.

Could you help me please ?

Thanks for your great work

 

The IP address in allow-transfer must be the IP address of the secondary DNS server. Also make sure that the firewall doesn't block port 53 (TCP and UDP)!

 

Thanks for your help Falko, but my firewall is off and ip address on my primary server is ip of my ISPconfig server (slave)... If you have another idea i take it

This is in my named.conf on my secondary DNS (ISPConfig)

Code:

zone "domain.org" {
         type slave;
         file "sec.domain.org";
         masters { ip of my primary DNS };
};

In fact the file "sec.domain.org" isn't created...

 

I found this on http://www.isc.org/index.pl?/sw/bind/FAQ.php:

 

I think it is a permission problem because all my aothers secondary DNS are ok.
On my ISPConfig i have this when i do a

Code:

ps aux | grep named

Code:

bind     21799  0.0  0.2 29404 2656 ?        Ss   11:42   0:00 /usr/sbin/named -u bind -t /var/lib/named

What are the good permissions for my directory /var/lib/named ?

Where should be created sec... files ?

When i restart my primary DNS i have this in my syslog :

Code:

Jan  4 12:06:30 xplora named[711]: client 195... ... ... #48283: zone transfer 'domain.org/IN' denied
Jan  4 12:06:30 xplora named[16155]: received notify for zone 'another_domain.net'
Jan  4 12:06:30 xplora named[16155]: received notify for zone 'another_domain.org'

It seems to be ok for others secondary DNS...

 

Please post the output of

Code:

ls -la /var/lib/named

Looks like your primary DNS is blocking the transfer which means it isn't a permissions problem on your secondary...

 

ok thanks Falko

Code:

ls -la /var/lib/named

Code:

drwxrwxr-x   5 root root 4096 2005-11-25 00:00 .
drwxr-xr-x  23 root root 4096 2005-11-25 14:48 ..
drwxrwxr-x   2 root root 4096 2005-11-24 18:35 dev
drwxrwxr-x   3 root root 4096 2005-11-25 00:00 etc
drwxrwxr-x   4 root root 4096 2005-11-25 00:00 var

I search on my primary DNS but i don't find where is the problem

 

This does look like a permissions problem! Is your Bind running as user named and group named? Then you should do this:

Code:

chown -R named:named /var/lib/named

otherwise Bind does not have the permission to write to that directory.

 

Ok Falko but i haven't any named user on my ispconfig (perfect setup sarge 3.1) !!!

when i do a ps aux :

Code:

ps aux | grep named

i have this answer :

Code:

bind     15714  0.0  0.2 29408 2664 ?        Ss   09:45   0:00 /usr/sbin/named -u bind -t /var/lib/named

Perhaps the solution is :

Code:

chown -R bind:bind /var/lib/named

What do you think ?

 

I have this answer now

Code:

Jan  5 10:58:25 jedi named[20909]: transfer of 'domain.org/IN' from 195 ... ... ...#53: failed while receiving responses: SERVFAIL

 

A dig on my primary server :

Code:

dig @localhost domain.org

I think there is a problem with permissions but i dont know where

 

Is your primary DNS the authoritative DNS for domain.org?

 

Yes it is the SOA...

 

This is ok !

there was a problem with my primary DNS on allow-transfer and notify options.

thanks for your help !
