Secondary DNS not working
hi guys

I am doing some testing for DNS
I got a master DNS(192.168.2.10) and I setup a slave DNS(192.168.2.11) but when I shutdown the Master DNS my linux client cannot resolve using the slave
any idea way?
This is the named.conf
Code:
options
{
    query-source    port 53;   
    directory "/var/named";
    dump-file         "data/cache_dump.db";
    statistics-file     "data/named_stats.txt";
    memstatistics-file     "data/named_mem_stats.txt";
    listen-on { 192.168.2.10; 127.0.0.1; };
};

logging
{
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };   
};

view "internal"
{
    match-clients        { localnets; };
    match-destinations    { localnets; };
    recursion yes;

    zone "training.com" {
        type master;
        notify yes;
        allow-query { any; };
        file "data/training.com.db";
    };

    zone "2.168.192.in-addr.arpa" {
        type master;
        notify yes;
        allow-query { any; };
        file "data/2.168.192.zone.db";
        };
   
    zone "." {
    type hint;
    file "data/named.ca";
    };
};

Data files

Code:

10        IN    PTR   masterdns ;
11        IN    PTR   secondarydns ;

Slave DNS
Zone Configuration
Code:
zone "training.com" {
        type slave;
        notify yes;
        allow-query { any; };
        file "data/sec.training.com.db";
        masters { 192.168.2.10; };
    };

    zone "2.168.192.in-addr.arpa" {
        type slave;
        notify yes;
        allow-query { any; };
        file "data/sec.2.168.192.zone.db";
        masters { 192.168.2.10; };

any idea?

thanks a lot

rlm_ippool_tool

RLM_IPPOOL_TOOL(8)					      System Manager's Manual						RLM_IPPOOL_TOOL(8)

NAME

       rlm_ippool_tool - dump the contents of the FreeRadius ippool database files

SYNOPSIS

       If an ipaddress is specified then that address is used to limit the actions or output.

       rlm_ippool_tool [-a] [-c] [-o] [-v] session-db index-db [ipaddress]

       Mark the entry nasIP/nasPort as having ipaddress

       rlm_ippool_tool -n session-db index-db ipaddress nasIP nasPort

       Update old format database to new.

       rlm_ippool_tool -u session-db new-session-db

DESCRIPTION

       rlm_ippool_tool dumps the contents of the FreeRADIUS ippool databases for analyses or for removal of active (stuck?) entries.

       Or with the -n argument adds a usage entry to the FreeRADIUS ippool databases.

OPTIONS

       -a     Print all active entries.

       -c     Report number of active entries.

       -r     Remove active entries.

       -v     Verbose report of all entries.

       -o     Assume old database format (nas/port pair, not md5 output).

       -n     Mark the entry nasIP/nasPort as having ipaddress.

       -u     Update old format database to new.

EXAMPLES

       Given the syntax in the FreeRadius radiusd.conf:

	       ippool myippool {
		   range-start = 192.168.1.0
		   range-stop = 192.168.1.255
		   [...]
		   session-db = ${raddbdir}/ip-pool.db
		   ip-index = ${raddbdir}/ip-index.db
	       }

       To see the number of active entries in this pool, use:

	       $ rlm_ippool_tool -c ip-pool.db ip-index.db
	       13

       To see all active entries in this pool, use:

	       $ rlm_ippool_tool -a ip-pool.db ip-index.db
	       192.168.1.5
	       192.168.1.82
	       192.168.1.244

	       192.168.1.27
	       [...]

       To see all information about the active entries in the use, use:

	       $ rlm_ippool_tool -av ip-pool.db ip-index.db
	       NAS:172.16.1.1 port:0x2e8 - ipaddr:192.168.1.5 active:1 cli:0 num:1

	       NAS:172.16.1.1 port:0x162 - ipaddr:192.168.1.27 active:1 cli:0 num:1
	       [...]

       To see only information of one entry, use:

	       $ rlm_ippool_tool -v ip-pool.db ip-index.db 192.168.1.1
	       NAS:172.16.1.1 port:0x90 - ipaddr:192.168.1.1 active:0 cli:0 num:0

	       $ rlm_ippool_tool -n ip-pool.db ip-index.db 192.168.1.1 172.16.1.1 0x90
	       rlm_ippool_tool: Allocating ip to nas/port: 172.16.1.1/144
