# 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
bash -c "$(curl -Ls https://raw.githubusercontent.com/xgadget-lab/nexttrace/main/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
```
### 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
```
