指导教师：张芳
1．实验目的：
学会使用常用ping ,ipconfig, nslookup, arp ,tracert等常用网络测试命令检测网络连通、了解网络的配置状态，跟踪路由诊断域名系统等相关网络问题。
2实验环境：
（1）运行windows 2000/2003/xp操作系统的PC一台
（2）每台PC机具有一块网卡，通过双绞线与局域网网相连。
（3）局域网能连接Internet
3．实验步骤：
ftp://10.16.23.2
用户名：1234567891234
密码：0123456
1、ARP: 显示和修改IP地址与物理地址之间的转换表
C:\Documents and Settings\ligong>ARP -a
Interface: 10.16.24.18 --- 0x10003
Internet Address Physical Address Type
192.168.1.3 00-00-00-00-00-00 invalid
C:\Documents and Settings\ligong>ARP -g
Interface: 10.16.24.18 --- 0x10003
Internet Address Physical Address Type
192.168.1.3 00-00-00-00-00-00 invalid
C:\Documents and Settings\ligong>ARP -d
C:\Documents and Settings\ligong>ARP -s
Displays and modifies the IP-to-Physical address translation tables used by address resolution protocol (ARP).
ARP -s inet_addr eth_addr [if_addr]
ARP -d inet_addr [if_addr]
ARP -a [inet_addr] [-N if_addr]
-a Displays current ARP entries by interrogating the current
protocol data. If inet_addr is specified, the IP and Physical addresses for only the specified computer are displayed. If
more than one network interface uses ARP, entries for each ARP table are displayed.
-g Same as -a.
inet_addr Specifies an internet address.
-N if_addr Displays the ARP entries for the network interface specified by if_addr.
-d Deletes the host specified by inet_addr. inet_addr may be
wildcarded with * to delete all hosts.
-s Adds the host and associates the Internet address inet_addr
with the Physical address eth_addr. The Physical address is given as 6 hexadecimal bytes separated by hyphens. The entry is permanent.
eth_addr Specifies a physical address.
if_addr If present, this specifies the Internet address of the
interface whose address translation table should be modified. If not present, the first applicable interface will be used. Example:
> arp -s 157.55.85.212 00-aa-00-62-c6-09 .... Adds a static entry.
> arp -a .... Displays the arp table.
2、ftp：（功能就不用描述了，请参看下面的具体用法）
