Description(required)

内网装有Pi-hole作为DNS服务器，发现一台主机(ubuntu 22.04 server without GUI amd64)超过了每秒并发1000次的默认阈值。

然后开始追踪，在该主机上用tcpdump查看，果然dns查询请求快得令人窒息。用netstat -anp | grep -w 53查看，除了systemd-resolver就是gopeed。

立刻停止gopeed，再用tcpdump看，请求消失了。然后再重启gopeed，tcpdump查看还是没有疯狂的dns请求。

那么在停止gopeed之前发生了什么？gopeed有一个bt下载任务，流量为0，但是在运行中，已经运行了许多天。再之前有许多bt下载任务已经完成。在web页面中把这个运行任务暂停，疯狂dns并不会停。

App Version(required)

gopeed -v 或 --version都没有显示，只好查询其下载日期：2024年3月30日，在本repo的release下载。

OS Version(required)

ubuntu 22.04 server without GUI amd64

在web页面重新启动该BT下载任务，又发生了不少DNS请求，但速率明显没那么高。
并且，web页面上看到本次是从0开始下载。（而以前曾下载过一部分）
而且这次启动后下载能达到100MB/s以上，之前是0。

看源代码中有下载
https://fastly.jsdelivr.net/gh/ngosang/trackerslist/trackers_all.txt

但是这个主机上用wget下载该文件是不成功的，原因估计是你懂的。

到了跟上次差不多的进度，又流量为0了，监测dns请求，有很多，但速率不到每秒1000。
在web页面上暂停了该任务，dns请求立刻停止了。这跟出故障时的表现很不一样。

能看到dns请求的域名吗，还有看你的描述应该是偶现的？看看能找到必现的步骤提供下吗，然后版本号在设置页面拉到最下面有，如果不是最新版建议更新到最新版再测试

感谢快速回复！版本号看了是1.5.6。看到有新版本1.5.7，打算明天试试。故障说明有误，不是超过每秒1000阈值，是每60秒1000次阈值。

重启gopeed进程后到目前为止无法复现故障。

原故障具体步骤是这样：

3月30日首次启动gopeed后就没有重启过。只用web来发布下载任务。
下载过多个bt任务，都已经完成，只剩下一个任务，卡进度到大约60～70样子，下载速率为0了。
没管这个任务，也没停，因为有时能看到下载个几百k。然后继续下载其他bt任务，任务量很大，都完成了。
到今天为止这个未完成的bt任务运行了大约有个把月。
大约一两周之前发现pi-hole告警，主机进行dns请求超过每60秒1000阈值。没空管。
今天查。
在主机上用tcpdump -nn port 53 and src host 192.168.9.88
其中主机ip是9.88, pi-hole是9.7和9.8。（双DNS）
看到高速飞过的dns请求列表。发现是gopeed干的。
到web页面暂停那个未完成bt任务。dns请求速度还是飞快。立刻杀gopeed进程。dns请求消失。
重启gopeed，web页面上看到那个未完成任务处于暂停或停止状态，只有运行按钮。此时没有大量dns请求。
运行任务，同时监控dns请求，web页面上显示从0进度下载，速度100MB/s以上。dns请求有一堆，但是比杀进程之前慢，而且到一定程度就会暂停，然后再十几秒的时候又请求一堆，再暂停。
web页一直等到进度卡住，下载速度为0。此时，dns请求也很多，但速率跟杀进程后差不多。
在web页暂停bt任务。还有一些dns请求发出，过几秒后停止了。

过了一个小时，再看dns，没有意外的dns请求了。（此时bt任务还是暂停状态）

部分域名如下：

原因应该已经定位了，大量的DNS请求是正常的因为一直在traker，问题的关键就在于DNS请求没有走缓存，把缓存问题解决了就行了。

参考：

Gopeed自己缓存dns会带来什么问题吗？如果没有的话，最好还是改一下。原因如下:
1）如果用户只使用默认dhcp，dns服务器可能是无线路由器也可能是猫，那么就要求这两种设备带缓存，如果没有，将导致大量的，对isp边缘dns服务器的请求，假如发生dns禁止某些解析的情况，随着gopeed用户量增大，有可能会造成类似上次暴风导致全国断网的事故。
2）如果用户使用DoH或梯子，将会造成大量的对外tcp请求，这对整个链路资源造成巨大压力，且暴露梯子。

还有就是可能进度卡住以后，疯狂寻找可用节点，因此发生超高速dns查询，每个查询都是不同域名。不知道这个猜测对不对，需要回看pihole日志进行分析，这个日志有7个多GB，如果你需要，可以提供给你。

golang默认是使用的系统的DNS解析，一般来说呢是会有缓存的(取决于系统的实现)，但是我构建web版的时候把CGO禁用掉了，导致golang使用了自己标准库里的DNS解析器，就没有缓存了，等我修复下构建脚本就行了，当时主要是为了方便交叉编译

好的谢谢！

另外我想了想，会不会已完成的任务也会造成dns请求。如果是，那么故障就说得通了。

这个bug确实存在，有人也反馈过，我一起看看吧
