在PC上查看ip地址

Microsoft Windows [版本 6.1.7601] 版权所有 (c) 2009 Microsoft Corporation。保留所有权利。 E:\Users\libra>ipconfig Windows IP 配置 … 以太网适配器 VMware Network Adapter VMnet8: 连接特定的 DNS 后缀 . . . . . . . : 本地链接 IPv6 地址. . . . . . . . : fe80::9074:b9f5:ddaf:9082%25 IPv4 地址 . . . . . . . . . . . . : 192.168.147.1 子网掩码 . . . . . . . . . . . . : 255.255.255.0 默认网关. . . . . . . . . . . . . : … E:\Users\libra>

【备注】pc和linux虚拟机在同个网段的

测试他们是否可以ping

lin@lin-machine:~$ ping 192.168.147.1 PING 192.168.147.1 (192.168.147.1) 56(84) bytes of data. 64 bytes from 192.168.147.1: icmp_seq=1 ttl=64 time=0.586 ms 64 bytes from 192.168.147.1: icmp_seq=2 ttl=64 time=0.442 ms 64 bytes from 192.168.147.1: icmp_seq=3 ttl=64 time=0.435 ms ^C — 192.168.147.1 ping statistics — 3 packets transmitted, 3 received, 0% packet loss, time 1999ms rtt min/avg/max/mdev = 0.435/0.487/0.586/0.074 ms

【可能存在一些异常的原因】注意： Windows 7 默认打开了系统防火墙，是禁ping的，如果在Linux下ping Windows

7，需要先关闭Windows 7 的防火墙。

没有问题后我们在SecureCRT上开始测试

【备注】根据自己的情况来写IP和主机名

来测试一下
