What is sshconfig-lint?

sshconfig-lint is a Rust CLI linter for OpenSSH client config files like ~/.ssh/config. It scans for duplicates, missing IdentityFiles, wildcard Host ordering pitfalls, weak algorithms like 3des-cbc or ssh-dss, repeated directives, insecure options, and Include cycles or unreadable globs. Run `sshconfig-lint` for colored output with line-specific hints, JSON export, or strict mode for CI—exit codes make it drop-in for github linter on pull request workflows.

Why is it gaining traction?

Tailored for SSH configs unlike broad tools like super linter github actions, kube linter github, or yaml linter github, it resolves Includes recursively with cycle detection and sorts output stably for reliable diffs. Devs hook it into linter github actions for pre-commit checks, treating warnings as errors via `--strict`. Hints like "move Host * to the end" fix issues fast, saving debug time on complex setups.

Who should use this?

DevOps engineers juggling multi-host SSH configs for bastions or git remotes. Sysadmins linting team-shared ~/.ssh/config files before deploys. Rust fans wanting a fast, native binary over scripting yaml linter github action alternatives for openssh client files.

Verdict

Solid early tool for personal SSH hygiene—install via Cargo or Homebrew, docs cover rules and CI use—but 12 stars and 1.0% credibility score signal it's pre-1.0 maturity. Grab it if your config's grown hairy; skip for production gates until more adoption.
