![]() Notes: It may be beneficial to use two access points (set on different, non-overlapping channels, with the same SSID/security) instead of range extenders/repeaters to extend wireless network coverage if a cable between your main router and the secondary access point is not an issue. ![]() Although range extenders/repeaters reach areas beyond the range of the central router, they also bounce back all the router's traffic, creating congestion and slowing the network. access point mode), however - it essentially halves your wireless bandwidth, as it has to use it to communicate with both your main AP and the clients. using an access point (or setting a device in repeater vs. There is a downside to using a repeater vs. The advantage to using a repeater/range extender is there is no need for a cable between the main router/modem and the repeater. Extenders are usually devices that only do repeating, and can't be set in any other mode. Extender has the same functionality as a repeater. Many routers/access points can be configured in " repeater" mode. Repeater is a wireless network device that repeats wireless signals to extend range without being connected with cable to either your router/modem, or your clients. You can also enjoy its DHCP subsystem which is easy to configure and use for a small network.Access point is a device connected with cable ( Cat5) to your main router/modem/internet, and serving clients wirelessly. sudo systemctl restart dnsmasq Conclusionĭnsmasq is an easy to configure DNS cache which can speed up internet browsing and the resolving of domain records on your systems. Restart dnsmasq and configure clients to obtain an IP address from this server. DNS server IP address (Probably Dnsmasq or different DNS server).You can use Dnsmasq to assign IP addresses to clients, either static or dynamic.Įdit the file a /etc/nf and provide DHCP options. Configure Dnsmasq as DHCP Server (Optional) You can confirm that we’re getting responses as configured. Since this is a test, I’ll modify runtime file /etc/nf $ sudo vim /etc/nf Edit /etc/network/interfaces for persistent configuration, or the file /etc/netplan/ on Ubuntu servers. To verify that Dnsmasq responds to the records we added, point DNS server of your servers to Dnsmasq server. sudo systemctl restart dnsmasq Step 3: Testing Dnsmasq DNS functionality You need to restart dnsmasq service after adding the records. Dnsmasq will reply to queries from clients using these records. Make any other changes you see relevant and restart dnsmasq when done: sudo systemctl restart dnsmasq Step 2: Adding DNS records to DnsmasqĪdd DNS records in the file. If you want to enable DNSSEC validation and caching, uncomment $ sudo dnssec Listen-address=127.0.0.1 # Set to Server IP for network responses # 3) Provides the domain part for "expand-hosts" ![]() # domain of all systems configured by DHCP # 2) Sets the "domain" DHCP option thereby potentially setting the # as the domain part matches this setting. # 1) Allows DHCP hosts to have fully qualified domain names, as long # automatically added to simple names in a hosts-file. # Set this (and domain: see below) if you want to have a domain # with each server strictly in the order they appear in Uncommenting this forces dnsmasq to try each query # servers it knows about and tries to favour servers to are known ![]() # By default, dnsmasq will send queries to any of the upstream # Never forward addresses in the non-routed address spaces. # Never forward plain names (without a dot or domain part) Setting this to zero completely disables DNS function, Here is minimal configuration # Listen on this specific port instead of the standard DNS port Configure Dnsmasq by modifying this file. The main configuration file for Dnsmasq is /etc/nf. echo nameserver 8.8.8.8 | sudo tee /etc/nfĭnsmasq is available on the apt repository, easy installation can be done by running: sudo apt update Lrwxrwxrwx 1 root root 39 Aug 8 15:52 /etc/nf ->. Run the following commands to disable the resolved service: sudo systemctl disable systemd-resolvedĪlso, remove the symlinked nf file $ ls -lh /etc/nf Ubuntu 18.04+ comes with systemd-resolve which you need to disable since it binds to port 53 which will conflict with Dnsmasq port.
