OpenWrt

Installation

Upload the software to the /root directory of the router with winscp or other tool, and execute the following command to install it.

opkg install smartdns.xxxxxxxx.xxxx.ipk
opkg install luci-app-smartdns.xxxxxxxx.xxxx.all.ipk
  • Note: For versions before OpenWrt 19.07, please install luci-app-smartdns.xxxxxxxxx.all-luci-compat-all package.

Configuration

Log in to the OpenWrt management page and open Services->SmartDNS to configure SmartDNS.

  • Add upstream DNS server configuration to Upstream Servers. It is recommended to configure multiple DNS servers at home and abroad.
  • Specify the IP address of a specific domain name in Domain Address, which can be used for ad blocking.

Start Service

There are two ways to use the SmartDNS service, one is directly as the primary DNS service, the other is as the upstream of dnsmasq.
By default, SmartDNS uses the first method. You can choose according to your needs in the following two ways.

Method 1: SmartDNS as primary DNS Server

  • Enable SmartDNS as primary DNS Server

    Log in to the router, click on Services->SmartDNS->port, input port 53, smartdns will run as primary DNS Server.

  • Check if the service is configured successfully

    Query domain name with nslookup -querytype=ptr smartdns See if the name item in the command result is displayed as smartdns or hostname, such as smartdns

    pi@raspberrypi:~/code/smartdns_build $ nslookup -querytype=ptr smartdns
Server:         192.168.1.1
Address:        192.168.1.1#53

Non-authoritative answer:
smartdns         name = smartdns.

Note

  • When the port of smartdns is 53, it will automatically take over dnsmasq as the primary dns. When configuring other ports, dnsmasq is re-enabled as primary dns.
  • If an exception occurs during this process, you can use the following command to restore dnsmasq as the primary DNS
uci delete dhcp.@dnsmasq[0].port
uci commit dhcp
/etc/init.d/dnsmasq restart
