Requires golang 1.7 or higher, you build grimd like any other golang application, for example to build for linux x64
env GOOS=linux GOARCH=amd64 go build -v github.com/looterz/grimd
A restful json api is exposed by default on the local interface, allowing you to build web applications that visualize requests, blocks and the cache. reaper is the default grimd web frontend.
Incoming requests spawn a goroutine and are served concurrently, and the block cache resides in-memory to allow for rapid lookups, while answered queries are cached allowing grimd to serve thousands of queries at once while maintaining a memory footprint of under 15mb for 100,000 blocked domains!
You can find examples of different daemon scripts for grimd on the wiki.
