我有一台主DNS服务器：192.168.56.102
一台client：192.168.56.101
操作系统均是ubuntu

下面是配置文件摘要（102上的）：

root@luis-VirtualBox:/var/cache/bind# pwd;cat db.test.com ;cat db.192
/var/cache/bind
;
; BIND data file for local loopback interface
;
$TTL 604800
@ IN SOA localhost. root.localhost. (
      2 ; Serial
   604800 ; Refresh
   86400 ; Retry
2419200 ; Expire
   604800 ) ; Negative Cache TTL
;
@ IN NS test.com.
@ IN A 127.0.0.1
local IN A 192.168.56.10
@       IN       A          192.168.56.102
www IN A 192.168.56.101
www1 IN    CNAME www
;
; BIND data file for local loopback interface
;
$TTL 604800
@ IN SOA localhost. root.localhost. (
      2 ; Serial
   604800 ; Refresh
   86400 ; Retry
2419200 ; Expire
   604800 ) ; Negative Cache TTL
;
@ IN NS test.com.
1.0.0 IN PTR local.test.com
102 IN PTR local.test.com
101 IN PTR www.test.com

正解没有问题,root@luis-VirtualBox:/etc/bind# host local.test.com
local.test.com has address 192.168.56.10

反解解不出来：

root@luis-VirtualBox:/etc/bind# host 192.168.56.10
Host 10.56.168.192.in-addr.arpa not found: 2(SERVFAIL)

而且bind服务启动后，一旦尝试反解syslog就报错：

root@luis-VirtualBox:/etc/bind# tail /var/log/syslog

Dec 26 18:03:55 luis-VirtualBox named[5238]: error (network unreachable) resolving 'G.ROOT-SERVERS.NET/AAAA/IN': 192.36.148.17#53

请高人指教！！！不胜感谢
