questions about DNS
我已经把我的有关DNS的配置文件给你发了一份,请有空帮我看一看,
还有我用dig -x 192.168.2.1命令的显示内容,请你帮我看看我的DNS服务器配置的对吗?
用什么工具能看出配置的对与否?
我用命令ping ljy.test.com后它找不到.(在/etc/hosts文件中我没有设置IP地址和ljy.test.com的对应关系.)
我的配置哪里有问题啊?请帮帮我.
请帮我看看我的DNS的配置有什么问题。
我用ping 命令：ping ljy.test.com后它显示找不到。
我用dig -x 192.168.2.1后显示的内容能说明它运行正常吗？还是有什么问题？
我现在配置了两块网卡，一块是：eth0 固定IP地址为：192.168.2.1
一块是：eth1 由主机动态分配IP地址为：192.168.0.29
为什么用nslookup显示的内容看eth1却能正常运行DNS?请帮我解释一下好吗？谢谢。

昨天我安装了两块网卡,都是D-LINK DE220 ISA的网卡.
但今天启动后它无法检测到网卡,我手工启动时eth0(由DHCP分配IP地址)时它显示:
eth0:trigger_send()called with the transmitter busy.
Hw. address read/write mismap 0
........同上..................1
........同上..................2
直到........5
这是怎么回事啊?你见过吗?

在/var/named/test.com 文件中的这句
ljy.test.com IN A 192.168.2.1
ljy.test.com 这里应该是以点结尾
是笔误还是你忘记了
如果是笔误，看你的配置应该没问题。
不过关于双网卡我可从未碰过

questions about DNS again.
你的意思是不是说所有类似这样的都在最后加点吗？
由 yuanyang 在 03-23-2003 09:46 发表:
是
如果你用简写如WWW IN A 192.168.2.1
则会自动把你的主机名ljy.test.com.连接到后面形成
www.ljy.test.com. IN A 192.168.2.1
