初识PsTools
在工作中我们都会想探测某个IP是否能通，基本上都使用过ping命令，但是某些服务器禁用了ping，而且有些时候也想探测某个IP的某个端口是否能通。之前的我一般都是用“telnet ip port”，但是我发现一个不好的体验就是没啥明显的结果，不通的时候会超时要等一下下，通的时候也没啥友好的提示。所以就搜到了【PStools下载】，里面的“psping”命令就很适合我这个要求。
PsTools是一款非常好用的远程管理工具应用软件，PsTools软件为用户提供了非常强大的功能，支持远程打开文件、终止进程、关闭重启计算机等。非常的实用。
其中包含的工具简介如下：
| 命令名 | 命令用途 |

1.使用ICMP ping
执行“psping -? i”
PsPing v2.10 - PsPing - ping, latency, bandwidth measurement utility
Copyright (C) 2012-2016 Mark Russinovich
Sysinternals - www.sysinternals.com
ICMP ping usage: psping [-t|-n count[s]] [-i interval] [-w count] [-q] [-h [buckets|val1,val2,...]] [-l requestsize[k]] [-6|-4] destination
-t Ping until stopped with Ctrl+C and type Ctrl+Break
for statistics.
-n Number of pings or append 's' to specify seconds e.g. '10s'.
-i Interval in seconds. Specify 0 for fast ping.
-w Warmup with the specified number of iterations (default is 1).
-q Don't output during pings.
-h Print histogram (default bucket count is 20).
If you specify a single argument, it's interpreted as a bucket
count and the histogram will contain that number of
buckets covering the entire time range of values.
Specify a comma-separated list of times to create a custom
histogram (e.g. "0.01,0.05,1,5,10").
-l Request size. Append 'k' for kilobytes.
-4 Force using IPv4.
-6 Force using IPv6.
For high-speed ping tests use -q and -i 0.
执行psping -4 -n 10 -w 2 -h 10 www.baidu.com
- -4 代表强制使用IPv4联机
- -n 代表正式ping包的个数，或者定义使用秒s作为单位
- -w 代表热身ping包的个数，即正式测试前先进行多少次热身测试连接
- -h 代表最小与最大延迟毫秒数
另外几个参数解释如下：
- -i 代表间隔秒数，快ping则设置为0
- -l 代表ping包大小，默认单位是byte。使用 k为单位代表kilobytes(KB)，使用m为单位代表megabytes(MB)
- -q 代表ping过程中不一个个输出值
- -t 代表长ping不停
- -6 代表强制使用IPv6联机
2.使用TCP ping
执行“psping -? t”

Sysinternals - www.sysinternals.com

-n Number of pings or append 's' to specify seconds e.g. '10s'.

-4 Force using IPv4.
-6 Force using IPv6.
For high-speed ping tests use -q and -i 0.
与ping功能相同的参数定义：
- -n 代表正式ping包的个数，或者定义使用秒s作为单位
- -w 代表热身ping包的个数，即正式测试前先进行多少次热身测试连接
- -h 代表最小与最大延迟毫秒数
- -i 代表间隔秒数，快ping则设置为0
- -l 代表ping包大小，默认单位是byte。使用 k为单位代表kilobytes(KB)，使用m为单位代表megabytes(MB)
- -q 代表ping过程中不一个个输出值

3.延迟测试
执行“psping -? l”
PsPing v2.10 - PsPing - ping, latency, bandwidth measurement utility

Sysinternals - www.sysinternals.com
TCP and UDP latency usage:
server: psping [-6|-4] [-f] -s address:port
client: psping -l requestsize[k|m] -n count[s] [-r] [-u] [-w count] [-f] [-h [buckets|val1,val2,...]] [-6|-4] destination:port
-l Request size. Append 'k' for kilobytes and 'm' for megabytes.
-n Number of sends/receives. Append 's' to specify seconds e.g. '10s'.
-r Receive from the server instead of sending.
-u UDP (default is TCP).
-w Warmup with the specified number of iterations (default is 5).
-f Open source firewall port during the run.
-h Print histogram (default bucket count is 20).
If you specify a single argument, it's interpreted as a bucket
count and the histogram will contain that number of
buckets covering the entire time range of values.
Specify a comma-separated list of times to create a custom
histogram (e.g. "0.01,0.05,1,5,10").
-4 Force using IPv4.
-6 Force using IPv6.
-s Server listening address and port.
The server can serve both latency and bandwidth tests and remains active until
you terminate it with Control-C.
执行psping -l 1500 -n 300 -h 10 www.qq.com:443
- -l 1500代表我发送的数据包大小为每个1500 Bytes，TCP联机在Layer 2 Ethernet中的MTU (Maximum Transmission Unit)通常以1500 Bytes为一个单位
- -n 300代表放松300个封包
4.带宽测试

Sysinternals - www.sysinternals.com
TCP and UDP bandwidth usage:
server: psping [-6|-4] [-f] -s address:port
client: psping -b -l requestsize[k|m] -n count[s] [-r] [-u [target]] [-i outstanding] [-w count] [-f] [-h [buckets|val1,val2,...]] [-6|-4] destination:port
-b Bandwidth test.
-l Request size. Append 'k' for kilobytes and 'm' for megabytes.
-n Number of sends/receives. Append 's' to specify seconds e.g. '10s'.
-r Receive from the server instead of sending.
-u UDP (default is TCP). Specify target bandwidth in MB/s.
-i Number of outstanding I/Os (default is min of 16 and 2x CPU cores).
-w Warmup for the specified iterations (default is 2x CPU cores).
-f Open source firewall port during the run.
-h Print histogram (default bucket count is 20).
If you specify a single argument, it's interpreted as a bucket
count and the histogram will contain that number of
buckets covering the entire time range of values.
Specify a comma-separated list of times to create a custom
histogram (e.g. "0.01,0.05,1,5,10").
-4 Force using IPv4.
-6 Force using IPv6.

The server can serve both latency and bandwidth tests and remains active until
you terminate it with Control-C.
执行psping -b -l 1500 -n 15000 www.qq.com:443
- -b 代表将进行带宽测试
- -l 1500代表使用大小1500Bytes的数据包
- -n 15000代表使用15000个数据包
执行结果显示我的PC和www.qq.com之间带宽为：526.12 KB/s
5.同功能的tcping工具
还有一个在禁止ping的情况下可以在windows上部署tcping64.exe或者tcping.exe工具来检测服务器端口是否开放windows下【tcping工具下载】，执行命令“tcping -t www.baidu.com 443”
总结
- 当发现当前做法有不方便时就是寻找更好解决方案的时候。
- 上面这些命令，相信在很多判断网络的场景很常用，以后可以happy了。
