# Tcping GO
|
||
|
||
一个使用 Golang 写的小工具，用于检测TCP端口是否开放
|
||
|
||
## 使用方法
|
||
|
||
你可以简单的测试一个域名(或 IP 地址)的某个端口是否开放，默认测试 80 端口
|
||
|
||
```shell
|
||
$ tcping.exe www.qq.com
|
||
Using www.qq.com A record: 101.91.42.232

|
||
[4] Reply from 101.91.42.232:80: time=11.862ms
|
||
|
||
Test finished, success 4/4 (100.00%)
|
||
min = 11.862ms, max = 15.086ms, avg = 13.976ms
|
||
```
|
||
|
||
也可以指定测试端口号，跟随在域名或 IP 地址后面
|
||
|
||
```shell
|
||
$ tcping.exe www.qq.com 443
|
||
Using www.qq.com A record: 101.91.42.232

|
||
|
||
Test finished, success 4/4 (100.00%)
|
||
min = 9.131ms, max = 12.348ms, avg = 10.485ms
|
||
```
|
||
|
||
使用 `-6` 指定使用IPv6（仅对域名有效）
|
||
|
||
```shell
|
||
$ tcping.exe www.qq.com -6
|
||
Using www.qq.com AAAA record: 240e:e1:a800:120::36

|
||
min = 14.510ms, max = 17.576ms, avg = 15.551ms
|
||
```
|
||
|
||
使用 `-c` 指定测试次数，默认为4次
|
||
|
||
使用 `-s` 指定超时时间，默认为2秒
|
||
|
||
使用 `-t` 来启用无限次测试模式
|
||
|
||
使用 `-f` 来启用快速模式，降低两次成功测试之间的间隔时间
