A fork of GoHole for the raspberypi GoHole is a DNS server written in Golang with the same idea than the PiHole, blocking advertisements's and tracking's domains.
The use of sql-lite as the query DB has been replaced with bolt DB and the use of Redis DB as a cache has been replaced with go-cache This allows a statically linked binary to be produced that builds into a small 6M docker container built using Docker and resinio
To start the DNS server you have to run the following command:
gohole -s
You can specify a config file with the command line argument -c. See the config_example.json file to see the structure.
You can also provide the -p argument to specify the port in which the DNS server will listen.
You can use the secure DNS server generating an AES encryption key using the command "gohole -gkey". Then, download it in your device and configure the GoHole CryptClient.
To block ads domains, you must add them to the cache DB. In order to do that, you must pass a blocklist file using the following command:
gohole -ab path/to/blacklist_file
If the list is published in a web server, you can provide the URL:
gohole -ab http://domain/path/to/blacklist_file
You can follow this link to get an updated list of available block content: https://github.com/StevenBlack/hosts
If you does not know any blacklist, you can see the file blacklists/list.txt. It contains the blacklists used by the PiHole. You can use a file with a list of blacklist like the blacklists/list.txt file to automatically add all the lists:
gohole -abl blacklists/list.txt
You can also block domains by using the following command:
gohole -ad google.com -ip4 0.0.0.0 -ip6 "::1"
and unblock domains by using the following command:
gohole -dd google.com
You can flush cache and logs DBs.
Flush domains cache
gohole -fcache
Flush logs
gohole -flog
You can see the stats and logs by using the following command line arguments:
See all the clients that have made a request
gohole -lc
See all request made by a client
gohole -lip <clientip>
See all clients that queried a domain
gohole -ld <clientip>
See top domains and number of queries for them
gohole -ldt -limit 10
You can use GoHole in a Docker container. A DockerFile is availble in the src code, this builds a docker image for raspberypi I'm using resinio to build and manage the containers.
You can send the statistics to your Graphite server. Configure it on your config file (host and port of the server). Then, you will be able to see your graphs in the Graphite web panel or in Grafana.
You can export the Grafana dashboard I used in the image using the grafana/GoHole.json file.
You can use the Graphite+Grafana Docker image from: https://github.com/kamon-io/docker-grafana-graphite
Tested on Go 1.10.3
