Does PI hole Use dnsmasq?

Does PI hole Use dnsmasq?

Pi-Hole, under the hood, is running DNSMasq. So we want to provide it with some additional hosts to resolve.

What is starting dnsmasq?

Dnsmasq is a lightweight, easy to configure, DNS forwarder and DHCP server. It is designed to provide DNS and optionally, DHCP, to a small network. Dnsmasq supports static and dynamic DHCP leases and BOOTP/TFTP for network booting of diskless machines (source: from the package description).

Is dnsmasq safe?

Over the years, multiple critical vulnerabilities have been found in dnsmasq. Recently, security researchers discovered new issues that continue to make dnsmasq vulnerable. These vulnerabilities can lead to DNS cache poisoning, denial of service (DoS) and possibly remote code execution (RCE).

Where is dnsmasq used?

The primary use of dnsmasq is to resolve DNS queries either for the device it’s running on or for other devices on the network, in the case of routers. The software forwards the queries to other DNS servers on the internet or serves the responses from a local cache to speed up the process.

What is Linux unbound?

Unbound is a validating, recursive, caching DNS resolver. It is designed to be fast and lean and incorporates modern features based on open standards. Unbound runs on FreeBSD, OpenBSD, NetBSD, MacOS, Linux and Microsoft Windows, with packages available for most platforms.

How do I uninstall a Raspberry Pi package?

Raspberry PI – removing applications

1. Remove applications you installed with apt-get with: sudo apt-get ––purge remove APPNAME. (replace APPNAME with the name of the app you want to remove)
2. To remove possible application orphans: sudo apt-get autoremove ––purge.

Why is dnsmasq running?

1 Answer. Because that’s what Network Manager uses to cache DNS locally. It’s from dnsmasq-base . This version of the package doesn’t include the server-start-up scripts that the dnsmasq package does.

Where is dnsmasq located?

Dnsmasq is configured in /etc/dnsmasq. conf . Your Linux distribution may also use /etc/default/dnsmasq , /etc/dnsmasq.

How do I stop dnsmasq?

The first part of disabling it is to change the configuration in /etc/NetworkManager/NetworkManager. conf by commenting out dns=dnsmasq . Next, you have to restart both the network-manager and networking services.

Where is dnsmasq cache?

By default, dnsmasq saves the original resolv. conf file in ‘/run/dnsmasq/resolv. conf’.

Why we use dnsmasq?

dnsmasq is a lightweight, easy to configure DNS forwarder, designed to provide DNS (and optionally DHCP and TFTP) services to a small-scale network. It can serve the names of local machines which are not in the global DNS.

Is unbound Safe?

Unbound is feature-rich with DNS Security with its harden-glue, access control, max randomness for query ID and ports, response scrubbing, case preservation, and Denial of Service or DoS protection features. These are just some of the features that make Unbound one of the most secure DNS server implementations.

What do you need to know about Dnsmasq?

dnsmasq is a lightweight DNS, TFTP and DHCP server. It is intended to provide coupled DNS and DHCP service to a LAN. Dnsmasq accepts DNS queries and either answers them from a small, local, cache or forwards them to a real, recursive, DNS server.

How to set upstream DNS server address in Dnsmasq?

The upstream DNS server addresses must then be specified in dnsmasq’s configuration file as server= server_address. Also add no-resolv so dnsmasq does not needlessly read /etc/resolv.conf which only contains the localhost addresses of itself.

How can I see the Dnsmasq lease file?

From a computer that is connected to the one with dnsmasq on it, configure it to use DHCP for automatic IP address assignment, then attempt to log into the network normally. If you inspect the /var/lib/misc/dnsmasq.leases file on the server, you should be able to see the lease.

How to set up Dnsmasq as a DNS caching daemon?

To set up dnsmasq as a DNS caching daemon on a single computer specify a listen-address directive, adding in the localhost IP address: listen-address=::1,127.0.0.1 To use this computer to listen on its LAN IP address for other computers on the network. It is recommended that you use a static LAN IP in this case. E.g.:
