openwrt-chinadns-ng's Issues

procd_set_param file ... 无效？

openwrt-chinadns-ng/files/chinadns-ng.init

Line 135 in 68ba156

procd_set_param file /etc/config/chinadns-ng

ipset_addr4_is_exists 报错

请教一个问题，目前我在 lean 的固件分支上编译了 k3 的 chinadns-ng，但是发现运行时会报错：

2020-11-22 14:28:18 ERR: [ipset_addr4_is_exists] received an error code from kernel: (-2) No such file or directory
2020-11-22 14:28:18 INF: [handle_remote_packet] reply [beacons.gcp.gvt2.com] from 127.0.0.1#6053, result: accept

好像是没有初始化对应 ipset list？

手动运行命令开启详细日志输出：

对应的 list 文件、chnroute 文件：

完整的配置：

config chinadns-ng
        option bind_addr '0.0.0.0'
        option bind_port '5353'
        option ipset_name4 'chnroute'
        option ipset_name6 'chnroute6'
        option gfwlist_file '/etc/chinadns-ng/gfwlist.txt'
        option chnlist_file '/etc/chinadns-ng/chinalist.txt'
        option timeout_sec '3'
        option chnlist_first '0'
        option fair_mode '0'
        option reuse_port '1'
        option china_dns '127.0.0.1#6053'
        option trust_dns '127.0.0.1#7053'
        option repeat_times '3'
        option noip_as_chnip '0'
        option enable '1'

其中 china_dns 与 trust_dns 配置的是 smartdns 的分组，并且确认是可查询的：

建议自动更新的脚本加上简单的校验

最近发现dns查询全走的代理，看了一下，周六自动更新的几个txt内容全部为：
root@OpenWrt:/etc/chinadns-ng# cat chnroute.txt

因为之前改了一下设置，没有代理openwrt本身，所以wget raw.github是可能无法正常更新的

conffiles 的问题

此处的配置是否无效？

openwrt-chinadns-ng/Makefile

Lines 34 to 38 in f5bd5d1

    
           define Package/chinadns-ng/conffiles 
        
           /etc/config/chinadns-ng 
        
           /etc/chinadns-ng/chnroute.txt 
        
           /etc/chinadns-ng/chnroute6.txt 
        
           endef

这里的 postrm 似乎会在升级（卸载旧版本？）的时候执行

openwrt-chinadns-ng/Makefile

Lines 52 to 56 in f5bd5d1

    
           define Package/chinadns-ng/postrm 
        
           #!/bin/sh 
        
           rm -r /etc/chinadns-ng 
        
           exit 0 
        
           endef

做了一个luci，建议作者可以集成进去。我把源码一起发上来。

基于rampis编译的chinadns-ng，以及luci，可以直接取用。
chinadns-ng_1.0-beta.15-1_mipsel_24kc.ipk
luci-app-chinadnsng_1.0-3_mipsel_24kc.ipk
其中luci与平台无关，各个平台都可以直接用
编译是基于19.07.1的sdk但是没有用到什么特殊的功能，应该从15以后的版本都没问题。
源码放在sdk的package下面，分类在
Utilities-->luci-chinadns-ng
make package/luci-app-chinadnsng/{clean,compile} -j V=99
即可
链接: https://pan.baidu.com/s/10bJbc_I6pM50-fqDilkklg 提取码: hhkc

另外目前采用ucitrack的功能希望能够让程序根据config的更改自行reload没办法实现，不知道为什么所以目前就没有添加uci-default文件，而是采用了在luci页面apply的时候执行reload，同时会在日志记录reload的信息。希望作者可以把service-trigger有空看看。

支持DNSSEC吗？

搭配DoT的话，貌似是推荐用DNSSEC.

建议luci增加自定义黑白名单和下载的gfwlist合并选项

rt，如果有一个合并功能选择就完美了

LuCI bugs

Makefile depends

上游更新到了 1.2.1 ，请问能否同步一下，谢谢！

将CHINADNS-NG编译好后如何设置和openwrt启动项？我编译好固件后发现ChinaDNS并没有自动运行

还有一个问题是，将luci页面编译进去后，我并没有在openwrt页面里面找到相应的CHINADNS NG的LUCI

有没有luci?

你好作者,编译这个应用会一起生成luci界面么?

建议luci增加从网址更新各种list功能

ipset 导入的速度太慢

https://github.com/pexcn/openwrt-chinadns-ng/blob/master/files/chinadns-ng.init#L75-L77

chinadns-ng service fail to start

I can run chinadns-ng using command line, such as '/usr/bin/chinadns-ng -b xxx -l xxx'. But I failed to run '/etc/init.d/chinadns-ng start'
I tried to figure out what was wrong by viewing /etc/init.d/chinadns-ng. In function start_chinadns_ng(), the variable $enable is set to 0, the script exited because of this.
I have no idea why $enable is 0. I am sure that I enabled chinadns-ng before staring it.
Please take a look at this situation when you have time, thanks.

update lan ip range?

add ::/0 for ipv6?

ref: https://en.wikipedia.org/wiki/Reserved_IP_addresses

lists nullable

Check:

openwrt-chinadns-ng/files/chinadns-ng.init

Lines 145 to 146 in 92fddbf

    
           append_param $1 gfwlist_file "-g" 
        
           append_param $1 chnlist_file "-m"

delete `/etc/chinadns-ng` folder after uninstall.

大佬有计划出个LUCI不

现在已经不强制依赖ipset，可选nftset了，可以把makefile里面的DEPENDS:=+ipset去掉了

一直用同一个端口号查询8.8.4.4，查询多了好像就不给答复了

我的5300端口是ss-tunnel到8.8.4.4:53了。用dig通过5300查询，一直可以得到答复。

5353是chinadns的端口，用dig通过5353查询国内一直可以，查询国外有时就不行。

感觉唯一的区别就是chinadns一直用一个端口发请求，dig是随机端口。

是不是用同一个端口短时间查询太多次，就会得不到答复？

给懒人减少搜寻的时间

希望能直接在makefile里添加ipset依赖...不得不说，我还是编译完了，上机测试才发现op默认是没有ipset编译进去的...

添加局域网 CIDR 到 chnroutes?

如何编译出mips_24kc的ipk呢

您好，
请教一下如何编译出mips_24kc的ipk呢，默认编译出来的包是chinadns-ng_1.0-beta.23-1_ar71xx.ipk，无法在我的NETGEAR WNDR3800上运行，好像是34kc的？
我的设备信息如下：

关于 LuCI

假如需要使用 LuCI 用户界面，可以参考以下链接：

Share a chinadns crontab script, which only update conf file when there is really updates available

#!/bin/sh -e

[ -d /etc/chinadns-ng ] || mkdir /etc/chinadns-ng
reload=0
for item in chnroute/chnroute chnroute/chnroute6 gfwlist/gfwlist chinalist/chinalist
do
    file=${item##*/}
    localsize=`wc -c /etc/chinadns-ng/${file}.txt | awk '{print $1}'`
    remotesize=`curl -s -I https://raw.githubusercontent.com/pexcn/daily/gh-pages/${item}.txt | grep -i "Content-Length:" | awk '{print $2}'`
    if [ $localsize != $remotesize ]; then
        wget --no-dns-cache --no-check-certificate -4 https://raw.githubusercontent.com/pexcn/daily/gh-pages/${item}.txt -O /tmp/${file}.tmp && [ "$?" == "0" ] && mv -f /tmp/${file}.tmp /etc/chinadns-ng/${file}.txt && reload=1 && echo "update ${file}, size ${localsize} -> ${remotesize}" || "update ${file} failed"
    else
        echo "ignore ${file}, size ${localsize}"
    fi
done

if [ $reload == 1 ]; then
    /etc/init.d/chinadns-ng restart
fi

不能打开日志吗？

我加了 -v 参数，但是却没有看见日志生成。不知道是不是我找的位置不对。

apply repeat_times when greater than 1

initscript `reload` function

~~Reload config only, do not destroy and recreate ipset.~~
