Tip checklist (authorized only)

  1. Confirm you may read memory stats on the host (lab VM / your sample / courseware).
  2. Prefer free -h / free -m short human views over unrelated dumps.
  3. Record -h/-m/-s flags you actually used.
  4. Quote total/used/free/available Evidence; redact hostnames.
  5. If you need disk free framing, cross-check free-disk-tips.
  6. Optional: vmstat sample → vmstat-tips; mem framing → vmstat-mem-tips.
  7. Optional: disk cousins → df-human-tips · du-summarize-tips.
  8. Redact sensitive labels before sharing; never dump process memory for secrets.

Allowed framing

  • Classroom labs reading RAM/swap on a syllabus VM.
  • Binding -h / -m settings as Evidence.
  • Documenting "free not installed / permission denied" as valid lab outcomes.
  • Comparing free ↔ vmstat under one binder.

Scope we will not cover

  • No crack/pirate/keygen via free.
  • No OOM-abuse / unauthorized-access / bypass PoCs.
  • No credential-theft via memory dumps.
  • No intentional free abuse against hosts you do not own.

Beginner path (authorized only)

  1. Obtain one syllabus-approved lab VM you control.
  2. Run free -h; quote total/used/available.
  3. Bind -h notes as Evidence; redact sensitive labels.
  4. Optional: compare with vmstat-tips.
  5. Stop at literacy — no dump cookbooks.
Which to pick
  • Prefer authorized, human-readable, redacted Evidence.
  • Use free-disk / vmstat peers when the syllabus asks.
  • No exploit, crack, or unauthorized-access framing.

For legal, authorized and educational use only.

FAQ

What is a "free mem tip" page in BinBench framing?

A checklist for reading authorized RAM/swap stats on hosts you own — not a cookbook for profiling hosts you do not control.

How does this relate to free-disk-tips and vmstat-mem-tips?

free-disk-tips covers disk free framing; vmstat-mem-tips covers vmstat memory. This page zooms on free memory Evidence — it does not overwrite those pages.

Can I free-profile other users\' production hosts I do not administer?

No. Authorization first. BinBench will not publish unauthorized-access recipes.

Does this teach exploit / OOM-abuse PoCs?

No. Mentions of exploit appear only as refusals. Authorized memory literacy only.

Does this teach credential theft via mem dumps?

No. Redact hostnames before sharing; never dump process memory for secrets.
