對于Windows下ping命令相信大家已經(jīng)再熟悉不過了,但是能把ping的功能發(fā)揮到最大的人卻并不是很多,當(dāng)然我也并不是說我可以讓ping發(fā)揮最大的功能,我也只不過經(jīng)常用ping這個工具,也總結(jié)了一些小經(jīng)驗,現(xiàn)在和大家分享一下。
現(xiàn)在我就參照ping命令的幫助說明來給大家說說我使用ping時會用到的技巧,ping只有在安裝了TCP/IP協(xié)議以后才可以使用:
ping [-t] [-a] [-n count] [-l length] [-f] [-i ttl] [-v tos] [-r count] [-s count] [[-j computer-list] | [-k computer-list]] [-wz 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地方主機(jī),直到你按下Control-C。
此功能沒有什么特別的技巧,不過可以配合其他參數(shù)使用,將在下面提到。
-a Resolve addresses to hostnames.
解析計算機(jī)NetBios名。
示例:C:\>ping -a 192.168.1.21

Ping statistics for 192.168.1.21:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms
從上面就可以知道IP為192.168.1.21的計算機(jī)NetBios名為iceblood.yofor.com。
-n count Number of echo requests to send.
發(fā)送count指定的Echo數(shù)據(jù)包數(shù)。
在默認(rèn)情況下,一般都只發(fā)送四個數(shù)據(jù)包,通過這個命令可以自己定義發(fā)送的個數(shù),對衡量網(wǎng)絡(luò)速度很有幫助,比如我想測試發(fā)送50個數(shù)據(jù)包的返回的平均時間為多少,最快時間為多少,最慢時間為多少就可以通過以下獲知:

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
從以上我就可以知道在給202.103.96.68發(fā)送50個數(shù)據(jù)包的過程當(dāng)中,返回了48個,其中有兩個由于未知原因丟失,這48個數(shù)據(jù)包當(dāng)中返回速度最快為40ms,最慢為51ms,平均速度為46ms。
