ping这个小工具大家都非常熟悉，但是他不能ping端口，当我们需要知道目的地址的某端口是否开放时，这时需要用到这个tcping小工具了，Windows没有自带这个小工具，需要自己下载下来，放到指定目录里面。
下载地址：点击打开链接 X64下载链接
放到C:\Windows\System32这个文件夹下
现在在测试一下：
这是32位的 tcping
64位的为tcping64，使用方法为：
官方有个英文版的具体参数使用说明
NAMEtcping - simulate "ping" over tcp by establishing a connection to network hosts.Measures the time for your system to [SYN], receive the target's [SYN][ACK] and send [ACK]. Note that the travel time forthe last ACK is not included - only the time it takes to be put on the wire a tthe sending end.SYNOPSIStcping [-tdsvf46] [-i interval] [-n times] [-w interval] [-b n] [-r times][-j depth] [--tee filename] [-f] destination [port]DESCRIPTIONtcping measures the time it takes to perform a TCP 3-way handshake (SYN, SYN/ACK, ACK) between itself and a remote host.The travel time of the outgoing final ACK is not included, only the (minimal) amount of time it has taken to drop it onthe wire at the near end. This allows the travel time of the (SYN, SYN/ACK) to approximate the travel time of theICMP (request, response) equivalent.OPTIONS-4 Prefer using IPv4-6 Prefer using IPv6-t ping continuously until stopped via control-c-n countsend _count_ pings and then stop. Default 4.-i intervalWait _interval_ seconds between pings. Default 1. Decimals permitted.-w intervalWait _interval_ seconds for a response. Default 2. Decimals permitted.-d include date and time on every output line-f Force sending at least one byte in addition to making the connection.-g countGive up after _count_ failed pings.-b typeEnable audible beeps.'-b 1' will beep "on down". If a host was up, but now its not, beep.'-b 2' will beep "on up". If a host was down, but now its up, beep.'-b 3' will beep "on change". If a host was one way, but now its the other, beep.'-b 4' will beep "always".-c only show output on a changed state-r countEvery _count_ pings, we will perform a new DNS lookup for the host in case it changed.-s Exit immediately upon a success. -v Print version and exit.-j Calculate jitter. Jitter is defined as the difference between the last response time and the historical average.-js depthCalculate jitter, as with -j but with an optional _depth_ argument specified. If _depth_ is specified tcping willuse the prior _depth_ values to calculate a rolling average.--tee _filename_Duplicate output to the _filename_ specified. Windows can still not be depended upon to have a useful command line environment. Don't tease me, *nix guys.--appendWhen using --tee, append to rather than overwrite the output file.--fileTreat the "destination" option as a filename. That file becomes a source of destinations, looped through on aline by line basis. Some options don't work in this mode and statistics will not be kept.destinationA DNS name, an IP address, or (in "http" mode) a URL.Do not specify the protocol ("http://") in "http" mode. Also do not specify server port via ":port" syntax.For instance: "tcping http://www.elifulkerson.com:8080/index.html" would failUse the style: "tcping www.elifulkerson.com/index.html 8080" instead.portA numeric TCP port, 1-65535. If not specified, defaults to 80.--headerinclude a header with the command line arguments and timestamp. Header is implied if using --tee.HTTP MODE OPTIONS -h Use "http" mode. In http mode we will attempt to GET the specified document and return additional values includingthe document's size, http response code, kbit/s.-u In "http" mode, include the target URL on each output line.--post Use POST instead of GET in http mode.--head Use HEAD instead of GET in http mode.--get Shorthand to invoke "http" mode for consistency's sake.--proxy-server _proxyserver_Connect to _proxyserver_ to request the url rather than the server indicated in the url itself.--proxy-port _port_Specify the numeric TCP port of the proxy server. Defaults to 3128.--proxy-credentials username:passwordSpecify a username:password pair which is sent as a 'Proxy-Authorization: Basic' header.RETURN VALUEtcping returns 0 if all pings are successful, 1 if zero pings are successful and 2 for mixed outcome.BUGS/REQUESTSPlease report bugs and feature requests to the author via contact information on http://www.elifulkerson.comAVAILABILITYtcping is available at http://www.elifulkerson.com/projects/tcping.php
