linux下的DNS配置？？？

Question

我在RH9下配置了DNS，用NSLOOKUP可以解析，但我在另一台WINDOWS系统的机子上把DNS设为RH9的IP，可以PING通IP，但PING不同域名，请问是怎么回事啊

Answer 1

[root@liunx80 etc]# nslookup www.xxx.com
Note:  nslookup is deprecated and may be removed from future releases.
Consider using the `dig' or `host' programs instead.  Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.
Server:         127.0.0.1
Address:        127.0.0.1#53

Name:   www.xxx.com
Address: 192.100.100.3
[root@liunx80 etc]# ping www.xxx.com
PING www.xxx.com (192.100.100.3) from 192.100.100.3 : 56(84) bytes of data.
64 bytes from www.xxx.com (192.100.100.3): icmp_seq=1 ttl=64 time=0.031 ms
64 bytes from www.xxx.com (192.100.100.3): icmp_seq=2 ttl=64 time=0.028 ms

--- www.xxx.com ping statistics ---
2 packets transmitted, 2 received, 0% loss, time 999ms
rtt min/avg/max/mdev = 0.028/0.029/0.031/0.005 ms

C:\>;nslookup www.xxx.com
*** Can't find server name for address 192.100.100.3: No response from server
*** Default servers are not available
Server:  UnKnown
Address:  192.100.100.3

*** UnKnown can't find www.xxx.com: No response from server

C:\>;ping www.xxx.com
Unknown host www.xxx.com.

Answer 4

你在win上 ping linux??对么?
service iptables status 看看是不是看着的?
ping用的是icmp .如果win上nslookup没有问题.
就不是你linux 的bind问题.
看看物理link和iptables.

Answer 5

是在WIN上ping的LINUX
[root@liunx80 etc]# service iptables status

Answer 6

好像少了个文件啊！在named.conf中加入：
zone "100.100.192.in-addr.arpa" IN  {
type master;
file "100.100.192.file";
}

之后再在/var/named/下建立100.100.192.file文件编辑它：参考以下设置规则。我记不清我的的了！！！！

Answer 7

你在本机上PING 域名通吗？

Answer 8

可以通

Answer 9

那你在WIN的机器上nslookup到DNS吗？
