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，但是某些服務器禁用了ping，而且有些時候也想探測某個IP的某個端口是否能通。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】，里面的“psping”命令就很適合我這個要求。
PsTools是一款非常好用的遠程管理工具應用軟件，PsTools軟件為用戶提供了非常強大的功能，支持遠程打開文件、終止進程、關閉重啟計算機等。非常的實用。

1.使用ICMP ping
執行“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.
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接
- -h 代表最小與最大延遲毫秒數
另外幾個參數解釋如下：
- -i 代表間隔秒數，快ping則設置為0
- -l 代表ping包大小，默認單位是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”

Sysinternals - www.sysinternals.com

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

與ping功能相同的參數定義：
- -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接
- -h 代表最小與最大延遲毫秒數
- -i 代表間隔秒數，快ping則設置為0
- -l 代表ping包大小，默認單位是byte。使用 k為單位代表kilobytes(KB)，使用m為單位代表megabytes(MB)

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代表我發送的數據包大小為每個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代表放松300個封包
4.帶寬測試

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.

-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.
執行psping -b -l 1500 -n 15000 www.qq.com:443
- -b 代表將進行帶寬測試
- -l 1500代表使用大小1500Bytes的數據包
- -n 15000代表使用15000個數據包
執行結果顯示我的PC和www.qq.com之間帶寬為：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工具來檢測服務器端口是否開放windows下【tcping工具下載】，執行命令“tcping -t www.baidu.com 443”
總結
- 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。
- 上面這些命令，相信在很多判斷網絡的場景很常用，以后可以happy了。
