木有这个libgcc_s 也

因为tls sni reset技术，只要域名符合gfw，即使获取的ipv6地址正常，也会被连接重置。
而大部分系统、浏览器都是ipv6优先的，只有在ipv6访问超时才会转而请求ipv4，这样就不可避免的导致连接时间的大大增加
另外并不是所有vps都支持ipv6的，所以即使路由器想把被墙的v6连接走代理，也不可行，所以还不如直接由smartdns给出“查询不到AAAA”的结果，让系统、浏览器误以为这些网站不支持v6，而直接走v4
诸如此类

用在pfsense上

dns server process failed

增加ipset、server功能。

如题，GFW或运营商在投毒时会随机选择某网段里的IP

芯片：ar9344
内核版本 ：3.18.79
openwrt 版本：OpenWrt Chaos Calmer 15.05.1 r49587
安装：luci-app-smartdns.1.2018.08.19-2204.all.ipk smartdns.1.2018.08.19-2204.ar71xx.ipk

在网页中尝试了主路由和上游dns模式两种方式，“在勾选配置页面中的Enable(启用)来启动SmartDNS”，均未运行SmartDNS。
怀疑是不是smartdns版本不对，改用smartdns.1.2018.08.19-2204.mips_24kc.ipk，也不能运行。
手动运行smartdns，不能运行，无进程。
使用“iptables -t nat -L PREROUTING | grep REDIRECT”检查路由规则，无路由规则。

PS.在上游dns模式，"去勾选Redirect选项"的表述建议改为"不勾选Redirect选项"。

LEDEX86 作为一个旁路由 怎么使用呢?
作为LEDEX86 我只有一个lan口没有网口
IPv4 上游
协议: 静态地址
地址: 192.168.5.254
子网掩码: 255.255.255.0
网关: 192.168.5.1
DNS 1: 192.168.5.254
已连接: 0h 21m 31s

可以这样使用么,没有wan口.

考虑到速度可以按照访问频率只刷新前XX个记录。
不知道现在是不是这样设计的，感觉好像每天第一次进网站还是能感觉到稍微卡了一下。

还有一个不成熟的想法（操作）不知道有没有用。
dnsmasq去掉cache，然后用all-server配置上几个dns包括smartdns，windows也去掉dns cache。
这样第一次访问是响应最快的地址，后面再次访问的时候smartdns有缓存了即是最快响应，又返回最快连接的地址。如果第一次返回的地址不能连接，刷新一下应该就变成smartdns的地址了。

我下载解压了smartdns.1.2018.08.19-2204.x86_64.tar.gz
在iTerm里运行install一直提示我输入选项
但是输入-i 进行安装后又回到了输入选项的界面

1、
经试用smartdns不能防御投毒，测试youtube.com会出现大量随机毒ip，建议增加毒ip过滤，
参考ChinaDNS： https://github.com/shadowsocks/ChinaDNS/blob/master/iplist.txt
2、
是否考虑增加缓存的落地/重载机制？
3、
编译时建议去掉libgcc_s.so，即 -static-libgcc 。
4、
rpath建议清理太不美观。

[ERROR][ fast_ping.c:330 ] sendto 2400:cb00:2048:1::6812:15e2, id 128, Permission denied
这样的日志，而且也没IPV6。
加个选项，如果启用就跳过那个ping环节，延迟就设9999，这样程序上最少改动能达到最好的效果，当然从收集列表移除也好。

安装和添加DNS的ip都正常，smartdns的本地端口设置是默认的5353还是要修改成53？
检查iptable，ip6table命令是否正确安装：固件自带这些命令，但是貌似不是所有的相关都装上了，是否要全部装上？
是否需要停用dnsmasq的dns解析功能？怎么做?
ip6tables-mod-nat这个驱动存在

首先说下我的使用场景，由于目前运营商普及了IPV6，dnsmqsq的ipset配合mwan3方式上网会导致解析IPV6，我主要使用smartdns来作为dnsmasq上游来过滤ipv6解析，但是smartdns进行ip优选的时候会调用默认路由IP，即pppoe-wan的ip，而mwan3本身不支持路由器本身策略路由，造成smartdns走运营商线路频繁访问被墙IP而且不通，存在隐私泄露问题与优选IP无效问题；

1.建议增加关闭IP优选的选项；
2.openwrt版本的配置增加bind ip配置选项或者增加一个优化IP时的源IP配置选项；

功能：
对返回的dns结果进行判断，如果该结果位于指定的ip列表内（比如china ip list），则信任位于该指定的ip列表内的dns供应商（比如114 dns）提供的结果；如果返回的dns结果不在指定的ip列表内，则信任该指定的ip列表外的dns供应商的结果（比如本地的dnscrypt-proxy）

发现smartdns并不支持以TCP方式查询dns（指本地向smartdns查询，并非指smartdns向上游dns查询）。
在某些场景，我还是用到本地TCP查询的。
希望作者大大考虑这个建议，感谢！

目前gfw封ip不再是以前那样，不管tcp、udp、icmp全部连不上，而是大部分ip只屏蔽tcp，这样就导致ping的通，连不上
1、像google等被墙的，不管怎么ping全超时，如果改成tcp ping，这样就可以直接借用ss等代理，获取到最准确的、走代理服务器后的ping值
2、像其他只封了tcp的，使用tcp ping可以避免出现ping通了，但是网页还是打不开的尴尬局面

如题，可以减少dns污染，可参考dnsmasq的dnssec-check-unsigned（感觉更有用）和dnssec
以及，建议支持设置支持dnssec的dns（有些dns不支持dnssec，例如阿里dns和opendns,dnsmasq开启"dnssec"选项后会无法解析dns）

右上角总提示有两项配置要保存，卸载，手动删配置再重新安装还是没用。而且开机不会自动运行了。

smartdns.cfg016bb1
smartdns.cfg016bb1.old_port+=
smartdns.cfg016bb1.old_port+=6053
smartdns.cfg016bb1.old_redirect+=
smartdns.cfg016bb1.old_redirect+=none

树莓派上试了一下，效果不错，想给R7800安上，CPU是ipq806x

系统是koolshare的ledex64，按论坛贴子弄的，不知道哪弄错了。

在SmartDNS 重定向模式为 无 的状态下，一旦保存并应用smartdns的配置，就会将原本禁用的本地DNS解析文件/tmp/resolv.conf.auto重新启用，导致dnsmasq 使用运营商的dns，造成dns污染

时不时的就进程关闭啦。这是啥情况叻？

我来说下场景，不知道具体原因，作为dnsmasq上游模式，开启ipv6，ping outlook.com ，返回结果为ipv6地址，ping值400ms左右，禁用ipv6模式，只返回ipv4，那么ping值在60ms左右，开启ipv6后，明显上网卡慢了，系统openwrt18.06.1

导入国内三大运营商的IP地址列表，配置文件里可以自定义运营商，比如电信，则返回查询到的IP地址里属于电信的那个结果，无需查询实际延迟，若有多个电信的IP或者无电信IP则按现有方案测速后返回，若为内网地址也测速后返回。
本地判断应该比实际测速要快吧？

我木有ipv6，可以屏蔽这个报错吗？不要显示出来。。。
还有smartdns是内置了多个上游DNS吗？有哪些呢？
