正确使用Windows的Ping命令

对于Windows下ping命令相信大家已经再熟悉不过了,但是能把ping的功能发挥到最大的人却并不是很多,当然我也并不是说我可以让ping发挥最大的功能,我也只不过经常用ping这个工具,也总结了一些小经验,现在和大家分享一下。
  
  现在我就参照ping命令的帮助说明来给大家说说我使用ping时会用到的技巧,ping只有在安装了TCP/IP协议以后才可以使用:
  
  ping [-t] [-a] [-n count] [-l length] [-f] [-i ttl] [-v tos] [-r count] [-s count] [[-j computer-list]   [-k computer-list]] [-w timeout] destination-list
  
  Options:
  
  -t Ping the specified host until stopped.To see statistics and continue - type Control-Break;To stop - type Control-C.
  
  不停的ping地方主机,直到你按下Control-C。
  
  此功能没有什么特别的技巧,不过可以配合其他参数使用,将在下面提到。
  
  -a Resolve addresses to hostnames.
  
  解析计算机NetBios名。
  
  示例:C:\>ping -a 192.168.1.21
  
  Pinging iceblood.yofor.com [192.168.1.21] with 32 bytes of data:
  
  Reply from 192.168.1.21: bytes=32 time<10ms ttl="254" bytes="32" ttl="254" bytes="32" ttl="254" bytes="32" ttl="254" sent =" 4," received =" 4," lost =" 0" minimum =" 0ms," maximum =" 0ms," average =" 0ms">ping -n 50 202.103.96.68
  
  Pinging 202.103.96.68 with 32 bytes of data:
  
  Reply from 202.103.96.68: bytes=32 time=50ms TTL=241
  
  Reply from 202.103.96.68: bytes=32 time=50ms TTL=241

  Ping statistics for 202.103.96.68:
  
  Packets: Sent = 50, Received = 48, Lost = 2 (4% loss),Approximate round trip times in milli-seconds:
  
  Minimum = 40ms, Maximum = 51ms, Average = 46ms
  
  从以上我就可以知道在给202.103.96.68发送50个数据包的过程当中,返回了48个,其中有两个由于未知原因丢失,这48个数据包当中返回速度最快为40ms,最慢为51ms,平均速度为46ms。
  
  -l size Send buffer size.
  
  定义echo数据包大小。
