-# traceroute

+<div align="center">

+<img src="asset/logo.png" height="200px" alt="NextTrace Logo"/>
+
+</div>
+
+# NextTrace
+
+一款开源的可视化路由跟踪工具，使用 Golang 开发。
+
+## How To Use
+
+### Install
+
+```bash
+#下载nt_install.sh
+curl -Ls https://github.com/xgadget-lab/nexttrace/raw/main/nt_install.sh -O
+#执行nt_install.sh
+sudo bash nt_install.sh
+```
+
+### Get Started
+
+`NextTrace`默认使用`icmp`协议发起`TraceRoute`请求，该协议同时支持`IPv4`和`IPv6`
+
+```bash
+# IPv4 ICMP Trace
+nexttrace 1.0.0.1
+
+# 表格打印（一次性输出全部跳数，需等待20-40秒）
+nexttrace -table 1.0.0.1
+
+# IPv6 ICMP Trace
+nexttrace 2606:4700:4700::1111
+```
+
+`NextTrace`也可以使用`TCP`和`UDP`协议发起`Traceroute`请求，不过目前只支持`IPv4`
+
+```bash
+# TCP SYN Trace
+nexttrace -T www.bing.com
+
+# 可以自行指定端口[此处为443]，默认80端口
+nexttrace -T -p 443 1.0.0.1
+
+# UDP Trace
+nexttrace -U 1.0.0.1
+
+nexttrace -U -p 53 1.0.0.1
+```
+
+`NextTrace`也同样支持一些进阶功能，如 IP 反向解析、并发数控制、模式切换等
+
+```bash
+# 无并发，每次只发送一个探测包
+nexttrace -r 1 www.hkix.net
+
+# 打开IP反向解析功能，在IPv6的骨干网定位辅助有较大帮助
+nexttrace -rdns www.bbix.net
+
+# 联合使用
+nexttrace -r 1 -q 1 -report www.time.com.my
+```
+
+### For Beginner
+
+如果你实在不想去了解这些参数如何使用，或目的只是为了快速测试服务器的到中国内地的线路，那么建议你使用本仓库的 `quicklytest.sh`
+
+使用此脚本前请先按照 [Install](#Install) 中的提示进行安装，才可使用，并按照提示进行操作即可。
+
+```bash
+#下载quicklytest.sh
+curl -Ls https://github.com/xgadget-lab/nexttrace/raw/main/quicklytest.sh -O
+#执行quicklytest.sh
+sudo bash quicklytest.sh
+```
+
+### IP 数据库
+
+目前使用的 IP 数据库默认为我们自己搭建的 API 服务，如果后期遇到滥用，我们可能会选择关闭。
+
+我们也会在后期开放服务端源代码，您也可以根据该项目的源码自行搭建属于您的 API 服务器。
+
+NextTrace 所有的的 IP 地理位置`API DEMO`可以参考[这里](https://github.com/xgadget-lab/nexttrace/blob/main/ipgeo/)
+
+### 全部用法详见 Usage 菜单
+
+```shell
+Usage of nexttrace:
+  -T    Use TCP SYN for tracerouting (default port is 80)
+  -U    Use UDP Package for tracerouting (default port is 53 in UDP)
+  -V    Check Version
+  -d string
+        Choose IP Geograph Data Provider [LeoMoeAPI, IP.SB, IPInfo, IPInsight] (default "LeoMoeAPI")
+  -m int
+        Set the max number of hops (max TTL to be reached). (default 30)
+  -p int
+        Set SYN Traceroute Port (default 80)
+  -q int
+        Set the number of probes per each hop. (default 3)
+  -r int
+        Set ParallelRequests number. It should be 1 when there is a multi-routing. (default 18)
+  -rdns
+        Set whether rDNS will be display
+  -realtime
+        Output trace results in runtime
+  -report
+        Route Path
+  -table
+        Output trace results as table
+```

+
+- 埃文科技 Paid Database ~ 95%
+
+**这里有朋友就要问了，为什么不全部使用埃文的付费库？**
+
+埃文的库一直都不是最优选择，IPIP.NET 才是，但是因为他们不对私，所以我们只能选择价格更便宜的埃文库。
+
+埃文家的数据库，在骨干网这块，准度可以说是非常糟糕，作为一款可视化的路由跟踪工具，骨干网的数据库准度非常重要。
+
+所以我们选择了尝试自行去校准一部分骨干网数据，但是由于我们缺乏检测节点以及志愿者，所以这项工作可能会进展的尤其缓慢。
