+Instruct a client to ignore the DNS server offers made by the router on Debian.
+  sudo nano /etc/dhcp/dhclient.conf
+In that file, find the section that begins with ''request subnet-mask'' and remove domain-name-servers from it.
+  request subnet-mask, broadcast-address, time-offset, routers,
+    domain-name, __domain-name-servers__, domain-search, host-name,
+    dhcp6.name-servers, dhcp6.domain-search, dhcp6.fqdn, dhcp6.sntp-servers,
+    netbios-name-servers, netbios-scope, interface-mtu,
+    rfc3442-classless-static-routes, ntp-servers;
+After that's removed, find the section that begins with ''prepend domain-name-servers 127.0.0.1;'' and change it as you see fit:
+  prepend domain-name-servers 192.168.1.20;
+  prepend domain-name-servers 192.168.1.21;
+  sudo systemctl restart networking
+After you restart networking, run ''cat /etc/resolv.conf'' and make sure the DNS is what you desired. In order to test whether there are DNS leaks, use tcpdump and adjust port to 53, 5335, 853, etc.
+  tcpdump -vv -x -X -s 1500 -i eth0 'port 853'
+In order to set a policy on Chrome to stop DOT, or DNS over TLS/https, do the following:
+  sudo nano /etc/opt/chrome/policies/managed/policies.json
+  {
+  "BrowserGuestModeEnabled": false,
+  "BrowserAddPersonEnabled": false,
+  "IncognitoModeAvailability": 1,
+  "DnsOverHttpsMode": false,
+  "ExtensionSettings": {"*": {"installation_mode": "blocked"}}
+  }
+Running Debian testing/unstable and your zfs modules suddenly won't load after a reboot and upgrade, well do the following:
+  sudo apt-get install linux-headers-$(uname -r)
+Alright ....
