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
PsExec	远程执行进程
PsFile	显示远程打开的文件
PsGetSid	显示计算机或用户的 SID
PsInfo	列出有关系统的信息
PsKill	按名称或进程 ID 终止进程
PsList	列出有关进程的详细信息
PsLoggedOn	查看在本地通过资源共享（包含所有资源）登录的用户
PsLogList	转储事件日志记录
PsPasswd	更改帐户密码
PsService	查看和控制服务
PsShutdown	关闭并重新启动（可选）计算机
PsSuspend	暂停进程
PsUptime	最后重启后系统运行的时间
psping	ICMP Ping、TCP Ping、延迟测试、带宽测试

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

  -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).

        histogram (e.g. "0.01,0.05,1,5,10").

  -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

3.延迟测试

执行“psping -? l”

PsPing v2.10 - PsPing - ping, latency, bandwidth measurement utility

Copyright (C) 2012-2016 Mark Russinovich

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

PsPing v2.10 - PsPing - ping, latency, bandwidth measurement utility

Copyright (C) 2012-2016 Mark Russinovich

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.

  -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 -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。
