eblocker-coredns

eBlocker DNS server based on CoreDNS.

This DNS server runs on the eBlocker, listening on UDP port 5300. It forwards queries to configured public servers.

Configuration

The configuration is read from Redis by the configupdater component.

The configupdater subscribes to the Redis channel dns_config. Two messages are supported:

• update: reload the configuration from key DnsServerConfig and reload the server;
• flush: reload the server, clearing the cache.

The server should run even when Redis is down. If there is no configuration available it creates a default configuration that forwards all requests to 1.1.1.1 or 9.9.9.9.

• domainfilter filters domains via eBlocker's ICAP server;
• filterstats counts blocked domains;
• resolverstats collects response times of upstream servers.
