Install and run

otlite install dnsgen
Installs dnsgen==1.0.4 into its own virtualenv. otlite lists what it will install and asks before it starts.
otlite run dnsgen -- --help
Dnsgen has no typed inputs. Everything after -- goes to dnsgen unchanged, so pass its own arguments there.

Linux and macOS, no Docker. It uses your Python and pipx when both are there, and otherwise brings its own Python. About otlite · otlite docs

What it takes

Dnsgen has no typed inputs, though it works on domain. Pass its own arguments after --; otlite run dnsgen -- --help lists them.

What a run leaves

Every run is saved under results/ where you run otlite (or --output, or OTLITE_RESULTS_DIR): what the tool printed, a sidecar with how it ran, and an envelope.

results/dnsgen/johndoe/<time>_dnsgen_johndoe_<run id>.txt
results/dnsgen/johndoe/<time>_dnsgen_johndoe_<run id>.meta.json
results/dnsgen/johndoe/<time>_dnsgen_johndoe_<run id>.envelope.json

{
  "envelope": 1,
  "tool": "dnsgen@1.0.4",
  "runtime": "otlite",
  "input": { "target": "johndoe" },
  "case": null,
  "started_at": "…", "ended_at": "…", "duration_ms": …,
  "exit_code": 0,
  "status": "complete",
  "entities": [{ "type": "url", "value": "…" }, …],
  "warnings": [],
  "output": { "path": "results/dnsgen/johndoe/<time>_dnsgen_johndoe_<run id>.txt", "sha256": "…", "bytes": … }
}

The envelope's shape, the same for every tool; values elided. Its entities are the emails, domains, IP addresses and URLs found in the output, or the tool's own when it prints them.

otlite results --tool dnsgen

otlite extract dnsgen

otlite diff dnsgen johndoe

List the saved runs, pull out every indicator, or compare the two latest runs against the same target.

With other tools

Batch runs can't pass it a value, so run it on its own.
