【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:~$ping192.168.147.1 PING192.168.147.1(192.168.147.1)56(84)bytesofdata. 64bytesfrom192.168.147.1:icmp_seq=1ttl=64time=0.586ms 64bytesfrom192.168.147.1:icmp_seq=2ttl=64time=0.442ms 64bytesfrom192.168.147.1:icmp_seq=3ttl=64time=0.435ms ^C ---192.168.147.1pingstatistics--- 3packetstransmitted,3received,0%packetloss,time1999ms rttmin/avg/max/mdev=0.435/0.487/0.586/0.074ms
【可能存在一些异常的原因】注意：Windows7默认打开了系统防火墙，是禁ping的，如果在Linux下pingWindows
7，需要先关闭Windows7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
