I have an OpenWRT router acting as an Wifi access point to a local network. No actual routing currently involved.

The ip adress of the wlan0 interface on the router is statically set to Dnsmasq is running as a service there providing DHCP and DNS.

My goal is to allow the router's web interface to be reachable to all computers in the network as http://router.net instead of having to type

LuCI, openWRT's web interface seems to allow multiple options to achieve this.

1 Network -> DHCP & DNS -> Static Leases

enter image description here

My initial idea was that this is for static leases for DHCP, but the deacription suggest it might also allow setting host names.

Static leases are used to assign fixed IP addresses and symbolic hostnames to DHCP clients.

I have entered both the MAC and the IP address of wlan0 on the router and the desired hostname, but this didn't result in being able to ping router_static_lease from a laptop in a subnet.

2 Network -> DHCP & DNS -> Resolv and Hosts Files -> Additional Hosts files

enter image description here

The second assumption was to add a line to /etc/hosts on the router and it will, because of dnsmasq, distribute this mapping to all the computers in the subnet.

That also didn't give the expected result.

2 Network -> Hostnames

enter image description here

The third approach was to add an entry to the above form. Again, no success

After setting all of those I restart the router and try pinging them from a computer in the subnet.

~$ ping router_static_lease
   ping: router_static_lease: Name or service not known
~$ ping router_hostnames
   ping: router_hostnames: Name or service not known
~$ ping router_etc_hosts
   ping: router_etc_hosts: Name or service not known

Running dig for those commands provides little help for it points to the systemd resolver.

~$ dig router_etc_hosts

Running ~$ systemd-resolve --status however shows that it is trying to resolve with the correct server

~$ systemd-resolve --status
Link 3 (wlp4s0)
      Current Scopes: DNS LLMNR/IPv4 LLMNR/IPv6
       LLMNR setting: yes
MulticastDNS setting: no
      DNSSEC setting: no
    DNSSEC supported: no
         DNS Servers:
          DNS Domain: lan

My question is what am I doing wrong and what would be the proper way to achieve this?

If you know how to do it in the command line, ignoring the web interface, that will also be helpful.

  • So what happens after adding the hostname and restarting dnsmasq? Does your browser say “domain not found”? What happens when you use nslookup or dig?

    Ah yes, underscores aren't valid in hostnames. If you obfuscated the real name: Don't. It makes helping you unnecessarily complicated.

  • @DanielB Opa cool :). That seems to have solved the problem. The setup in Network -> Hostnames is the entry that allows resolving in the subnet. If you would elaborate on why this one works and the purpose of the other ones I would accept it as an answer. Jun 20, 2017 at 21:06

I have exact the same configuration on my lab and it works well In this case you are using DNS mask and not bind servers so you only have alias not records. For you can dig the hostnames your router has to be on your guests dns resolution as dns server.
