- new json configuration: added multiple configs, ip groups/ip aliases and timetables
- added multiple configurations:
- each configuration has his own upstream, singlefilters, doublefilters, blackholeip hostsfile
- cache DB is global to all configs
- BL downloader and parser is optimized: each BL source is downloaded/parsed only once
- TODO:
- implement configuration selection based on source IPs and timetables
- unused code cleanup

zabov
Tiny replacement for piHole DNS filter
Still Work in progress, usable.
Idea is to produce a very simple, no-web-interface , IP DNS blocker.
INSTALL
Zabov requires golang 1.13 or later.
git clone https://git.keinpfusch.net/Loweel/zabov.git cd zabov go get go build -mod=vendor
Then, edit config.json: please notice config.json must be in the same folder of the executable you run.
Just a few words about "singlefilters" and "doublefilters":
Data must be downloaded from URLs of blacklist mantainers.They may come in different formats.
There are two kinds of blacklists:
One is the format zabov calls "singlefilter", where we find a single column , full of domains:
domain1.com domain2.com domain3.com
The second is the format zabov calls "doublefilter" (a file in "/etc/hosts" format, to be precise), where there is an IP, usually localhost or 0.0.0.0 and then the domain:
127.0.0.1 domain1.com 127.0.0.1 domain2.com 127.0.0.1 domain3.com
This is why configuration file has two separated items.
The config file should look like:
{
"zabov": {
"port":"53",
"proto":"udp",
"ipaddr":"127.0.0.1",
"upstream":"./dns-upstream.txt",
"cachettl": "4",
"killfilettl": "12",
"singlefilters":"./urls-hosts.txt" ,
"doublefilters":"./urls-domains.txt",
"blackholeip":"127.0.0.1",
"hostsfile":"./urls-local.txt"
}
}
Where:
- port is the port number. Usually is 53, you can change for docker, if you like
- proto is the protocol. Choices are "udp", "tcp", "tcp/udp"
- ipaddr is the port to listen to. Maybe empty, (which will result in listening to 0.0.0.0) to avoid issues with docker.
- upstream: file containing all DNS we want to query : each line in format IP:PORT
- cachettl: amount of time the cache is kept (in hours)
- killfilettl: refresh time for killfiles
- singlefilters: name of the file for blacklists following the "singlefilter" schema.(one URL per line)
- doublefilters: name of the file, for blacklists following the "doublefilter" schema.(one URL per line)
- blackholeip: IP address to return when the IP is banned. This is because you may want to avoid MX issues, mail loops on localhost, or you have a web server running on localhost
- hostsfile: path where you keep your local blacklistfile : this is in the format "singlefilter", meaning one domain per line, unlike hosts file.
