使用“dokodemo-door”解析DNS时遇到的问题 #1129

Closed flukaxkx closed 5 years ago

flukaxkx commented 6 years ago

1) 你正在使用哪个版本的 V2Ray？ 3.23

2) 你的使用场景是什么？ 在路由器上做透明代理，目前只用iptables代理了tcp，udp部分还没弄明白。 同时用dnsmasq配合做dns查询与缓存。 采用黑名单模式，只有黑名单中的网站用 8.8.8.8解析，并走代理， 默认是 freedom模式，用114.114.114.114解析，并直接访问。

3) 你看到的不正常的现象是什么？ iplocation.net在黑名单中，长时间不访问后的第一次访问，显示的是本机的真实ip， 此后刷新才会显示vps的ip。 类似的，一些黑名单中的网站，第一次访问都会出现解析不到dns的问题， 等一下再刷新就好了。

4) 你期待看到的正确表现是怎样的？ 我想请教的问题是： 1，上述问题出在何处，如何能够更正。 2，在iptables不设置udp转发的情况下，按照我的客户端配置，把gfwlist中的网站直接用8.8.8.8解析和用127.0.0.1#5353解析有什么区别(如下述的两行设置)，

server=/iplocation.net/8.8.8.8#53  //将dns请求通过rules代理至8.8.8.8
server=/iplocation.net/127.0.0.1#5353  //将dns请求转制dokodemo-door，再转至8.8.8.8

会不会有一种配置导致解析过程没有通过v2ray而导致结果被污染。

5) 请附上你的配置（提交 Issue 前请隐藏服务器端IP地址）。 客户端配置:

你和我开始搞的配置简直一模一样，不过我不在路由上，而是局域网上的一个虚拟机做软路由。DNS解析的问题困扰了我很久，经常在DNS解析这里V2ray就死火了，这样什么网站都看不了，在dnsmasq fowarded的时候看看v2ray的error.log是否有断开的提示，我的v2ray服务端是websocket+tls+web方式，理论上应该不会被墙盯上，可是还是有大量failed to dial websocket的错误提示，后来我感觉这个错误提示对网页浏览没影响，因为很快就重连上了，可是dns查询的时候一旦出现这个错误，浏览器就会收到dns timeout错误，于是彻底翻不了墙。

于是我改成不用v2ray来转发dns查询了，改成用dns-over-https的方式来，项目网站在 http://dns-over-https.com/ 。远端dns服务器使用Cloudflare的服务：https://cloudflare-dns.com/dns-query ，直连不走V2ray通道，分流依然用dnsmasq，目前这个方案运行了两天，没有再出现dns timeout的错误。

flukaxkx commented 6 years ago

这个好啊，可以通过tcp来解析dns了。

flukaxkx commented 6 years ago

我现在换了一种类似的思路了，可以直接在linux盒子上做透明网关，实现路由、分流、upnp等各种功能了。 还是黑名单模式，基本思路是：

  1. 安装v2ray。v2ray的inbound为socks入口，虽然用不上但还是留着吧，不改了；inboundDetour为科学上网（port：8010）和科学dns的入口（port：5353），和上面的设置一样。outboard默认改为科学出口；outboardDetour，为直连出口，其实也用不上了。routing里面的科学网站也不需要了，我加了8.8.8.8和8.8.4.4走proxy，貌似不加是不是也可以。
  2. dnsmasq+ipset。dnsmasq中设置也同上，不向上查询dns，把需要科学上网的网站通过 /etc/dnsmasq.d/scisites.conf 统统转到127.0.0.1#5353去，并记录进ipset scisites记录，其他统统走144.144.144.144解析。
  3. iptables。将匹配ipset scisites记录的ip的tcp和udp流量统统转到127.0.0.1的8010端口，其他的默认。这样就不用建立什么V2RAY链。内外网之间用SNAT联通，如果内网有NAS什么的，可以再写几个DNAT进行端口映射，就和普通路由器中的“虚拟服务器”一样的写法。
  4. 安装miniupnpd，建立upnp。
  5. 现在可以说科学是无国界的了，当然科学家是有国籍的哈。

这样做的好处：

  1. 简单。iptables严重的超出我的智力范围，尤其是mangle表，还是杀了我吧。
  2. 快速一点点。通过dnsmasq+ipset+iptables分流，比原来用v2ray的routing分流感觉上快一点点，毕竟信息走的路径简单了，而且v2ray也可以专心干她最拿手的事。
  3. 稳定，省电。把科学网站名单放进v2ray的config.json，v2ary占用的内存和cpu暴涨，对于没有风扇的盒子来说负担还是太重了。
  4. 减小科学流量，在战略上还是要重视伟大的华尔。
  5. 对于要有大量p2p下载流量的场景，可以保证国外的p2p节点不会走vps流量。

这样做的缺点和注意事项：

  1. 长时间不上的科学网站，首次上的时候解析会比较慢，但是不会有解析错误的问题了，只是会显示解析超时，等几秒刷一次就好了。
  2. 黑名单维护起来比较费事。建议黑名单使用gfwlist2dnsmasq.sh来做，有网友把它加到rc.local里面，每次重启都会更新，我还是选择手动了。建议在/etc/dnsmasq.d目录下再建一个othersites.conf，把自己常用的，没有被墙的，但在墙内上又比较慢的网站加进去，提升上网体验。
  3. 不知道是不是pppoe的缘故，每次启动的时候iptables-persistent都不能restore规则，于是我只好在rc.local里面重新加载一遍（iptables-restore < /etc/iptables/rules.v4）。
  4. ipset记录每次重启都会消失，在rc.local里面重建（ipset -N scisites hash:ip）
  5. 生命在于折腾。折腾完之后才发现自己并没有多少科学上网的需求，当没有什么可折腾的时候非常非常空虚，比如现在。

真是够复杂的…太厉害了，折腾好了之后的空虚感，hmm…握手！
