1.        Using the appropriate command, verify that the LAN hardware is installed and is recongnized by the system. What Command(s) did you use?
A.#lanscan
B.#ifconfig
C.#lanadmin

b


使用lanscan可以查找系统中有几块网卡及其相关的信息，在本工程中可以看到每台机器上有  
lan0、lan1、lan2等三块网卡，其作用如下：  
1、 lan0:心跳线heart beating network  
双机心跳线使用10 Base-T网卡，配置在同一网段196.1.1.0，使用直连线连接。（直连线的制作需要  
自己动手，HP不提供，请参阅有关文档）  
2、 lan1:工作用网卡  
可通过系统工具sam进行将网卡IP地址更改到需要的工作网段上，并可通过查看  
/etc/rc.config.d/netconf文件来查看当前网络的配置情况，在配置完工作网卡的IP地址后，  
要选定一个工作用的IP地址，应和工作网卡在同一个网段，如：  
CRCT1: 192.168.1.10  
CRCT2: 192.168.1.11  
CRCT: 192.168.1.15  
3、 lan2:备份网卡

Q: 在solaris下，如何查看网络是否配置成功？
A: 可以采用命令Ifconfig -a来查看，如果网卡绑定ip成功，而不是显示0.0.0.0
就证明网卡配置基本无误，主要检查网络介质(网线,RJ45插头...)是否损坏。

2.        use which command to view the networking software that is loaded?
A.        #swverify
B.        #setld

10.        which command check swap size?
A. #swap –s
B. #swapinfo –t
C. #more /etc/fstab
D. #df –k


11.        How come I can't get all of my swap space?
A.        default kernel parameter “maxswapchunks” is 512MB,if you config more swap, you need to increase its size
B.        default kernel parameter “maxswapsize” is 512MB,if you config more swap, you need to increase its size
C.        default kernel parameter “maxswapx” is 512MB,if you config more swap, you need to increase its size



12.        How do I change the hostname, IP address, DNS Server, etc?
A.        modify /etc/netconf
B.        #/sbin/set_parms <parameter>;
C.        #uname to change hostname,#ifconfig to modify IP Address,modify /etc/named files to change DNS server.

C

在我们dns开始工作了，是不是我们的工作已经OK了呢？不，不，不，named.conf文件还有很多东西需要我们配置呢。

DNS的配置文件named.conf是有非常多的可选项的，这里只是介绍一点常用的配置。如果你觉得还想继续研究下去，那也不需要在网上到处找资料的，直接用“man named.conf”就可以得到一个非常非常详细的说明。
