Tip checklist (authorized only)

  1. Confirm you may scan the tree (lab VM / your server / courseware).
  2. Prefer a scoped path (ncdu ~/project) over scanning / on shared hosts.
  3. Record top directories and sizes you actually navigate to.
  4. Quote a short top-N from the UI; avoid exporting whole-home scans unredacted.
  5. If a non-interactive summary is enough, cross-check du-disk-usage-tips.
  6. Optional: filesystem totals → df-disk-tips; inodes → df-inode-tips.
  7. Optional: block layout → lsblk-disk-tips; Mem/Swap → free-disk-tips.
  8. Redact usernames, home paths, and sensitive project names before sharing.

Allowed framing

  • Classroom labs drilling into build caches on trees you own.
  • Binding top directory + size notes as Evidence.
  • Documenting "ncdu not installed / permission denied / empty tree" as valid lab outcomes.
  • Comparing ncdu ↔ du / df under one binder.

Scope we will not cover

  • No crack/pirate/keygen via ncdu.
  • No persistence / unauthorized-access / bypass PoCs via ncdu.
  • No credential-theft via exported scan dumps.
  • No intentional wipe/fill recipes against storage you do not own.

Beginner path (authorized only)

  1. Obtain one syllabus-approved lab VM you control.
  2. Run ncdu on a project tree you own; note top directories.
  3. Bind top path + size as Evidence; redact sensitive labels.
  4. Optional: compare with du-disk-usage-tips.
  5. Stop at literacy — no unauthorized-access cookbooks.
Which to pick
  • Prefer authorized, short, redacted Evidence.
  • Use du / df / inode peers when the syllabus asks.
  • No exploit, crack, or unauthorized-access framing.

FAQ

What is an "ncdu scan tip" page in BinBench framing?

A checklist for running authorized interactive ncdu scans on hosts you own — not a cookbook for scanning trees you do not control.

How does this relate to du-disk-usage-tips?

du-disk-usage-tips covers CLI du summaries. This page zooms on interactive ncdu Evidence — it does not overwrite that page.

Can I ncdu other users\' production hosts I do not administer?

No. Authorization first. BinBench will not publish crack/bypass or unauthorized-access recipes.

Does this teach exploit / bypass PoCs via ncdu?

No. Mentions of exploit/bypass appear only as refusals. Authorized ncdu literacy only.

Does this teach credential theft via exported scan files?

No. Redact usernames and sensitive paths before exporting or sharing scan output.
