初識PsTools

    在工作中我們都會想探測某個IP是否能通，基本上都使用過ping命令，但是某些伺服器禁用了ping，而且有些時候也想探測某個IP的某個埠是否能通。之前的我一般都是用“telnet ip port”，但是我發現一個不好的體驗就是沒啥明顯的結果，不通的時候會超時要等一下下，通的時候也沒啥友好的提示。所以就搜到了【PStools下載】，裡面的“psping”命令就很適合我這個要求。
    PsTools是一款非常好用的遠端管理工具應用軟體，PsTools軟體為使用者提供了非常強大的功能，支援遠端開啟檔案、終止程序、關閉重啟計算機等。非常的實用。

其中包含的工具簡介如下：

psping

    下面是“psing -?”檢視的幫助資訊

bandwidth measurement.

Help usage: psping -? [i|t|l|b]
   -? i   Usage for ICMP ping.
   -? t   Usage for TCP ping.
   -? l   Usage for latency test.
   -? b   Usage for bandwidth test.

1.使用ICMP ping

    執行“psping -? i”

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.

執行psping -4 -n 10 -w 2 -h 10 www.baidu.com

• -4 代表強制使用IPv4聯機
• -n 代表正式ping包的個數，或者定義使用秒s作為單位
• -w 代表熱身ping包的個數，即正式測試前先進行多少次熱身測試連線
• -h 代表最小與最大延遲毫秒數
  

另外幾個引數解釋如下：

• -i 代表間隔秒數，快ping則設定為0
• -l 代表ping包大小，預設單位是byte。使用 k為單位代表kilobytes(KB)，使用m為單位代表megabytes(MB)
• -q 代表ping過程中不一個個輸出值
• -t 代表長ping不停
• -6 代表強制使用IPv6聯機

2.使用TCP ping

    執行“psping -? t”

Copyright (C) 2012-2016 Mark Russinovich
Sysinternals - www.sysinternals.com

TCP ping usage: psping [-t|-n count[s]] [-i interval] [-w count] [-q] [-h [buckets|val1,val2,...]] [-6|-4] destination:port
  -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").
  -4    Force using IPv4.
  -6    Force using IPv6.

For high-speed ping tests use -q and -i 0.

與ping功能相同的引數定義：

• -n 代表正式ping包的個數，或者定義使用秒s作為單位
• -w 代表熱身ping包的個數，即正式測試前先進行多少次熱身測試連線
• -h 代表最小與最大延遲毫秒數
• -i 代表間隔秒數，快ping則設定為0
• -l 代表ping包大小，預設單位是byte。使用 k為單位代表kilobytes(KB)，使用m為單位代表megabytes(MB)
• -q 代表ping過程中不一個個輸出值
• -t 代表長ping不停
• -4 代表強制使用IPv4聯機
• -6 代表強制使用IPv6聯機

3.延遲測試

    執行“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.

執行psping -l 1500 -n 300 -h 10 www.qq.com:443

• -l 1500代表我傳送的資料包大小為每個1500 Bytes，TCP聯機在Layer 2 Ethernet中的MTU (Maximum Transmission Unit)通常以1500 Bytes為一個單位
• -n 300代表放鬆300個封包

4.頻寬測試

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.

執行psping -b -l 1500 -n 15000 www.qq.com:443

• -b 代表將進行頻寬測試
• -l 1500代表使用大小1500Bytes的資料包
• -n 15000代表使用15000個數據包

執行結果顯示我的PC和www.qq.com之間頻寬為：526.12 KB/s

5.同功能的tcping工具

    還有一個在禁止ping的情況下可以在windows上部署tcping64.exe或者tcping.exe工具來檢測伺服器埠是否開放windows下【tcping工具下載】，執行命令“tcping -t www.baidu.com 443”

總結

1. 當發現當前做法有不方便時就是尋找更好解決方案的時候。
2. 上面這些命令，相信在很多判斷網路的場景很常用，以後可以happy了。
