Quick answer

faillock helps authorized labs sample PAM lockout literacy on hosts they own. Pair with lastb-tips, fail2ban-tips, pwck-tips, chage-tips, journalctl-logs-tips. Prefer lab VMs — never unlock or attack foreign accounts without permission.

Tip checklist (authorized only)

  1. Confirm you may inspect faillock Evidence on the host (lab VM / syllabus box you own or were given access to).
  2. Prefer read-only --user queries — never --reset production accounts without change control and ticket notes.
  3. Record short factual notes; quote short Evidence (user, fail count, recent tty — redact as needed).
  4. Optional: btmp history → lastb-tips.
  5. Optional: ban jails → fail2ban-tips.
  6. Optional: passwd integrity → pwck-tips.
  7. Redact usernames and hostnames if policy requires.
  8. Stop at literacy — no exploit / unauthorized unlock cookbooks.

Allowed framing

  • Classroom labs reading faillock tallies on authorized disposable hosts.
  • Binding short factual notes as Evidence.
  • Documenting expected vs observed lockout thresholds for authorized inventory notes.
  • Comparing faillock ↔ lastb / fail2ban / pwck peer tip pages under one binder.
  • Resetting lab-only accounts when the syllabus explicitly authorizes a reset drill.

Scope we will not cover

  • No crack/pirate/keygen via faillock.
  • No intentional lockout / DoS PoCs against foreign accounts.
  • No credential-theft via PAM tallies against hosts you do not own.
  • No bypass cookbooks that disable pam_faillock without authorization.

Beginner path (authorized only)

  1. Obtain one syllabus-approved lab host you control or may inspect.
  2. Run a short read-only faillock --user <labuser> sample; quote success.
  3. Bind notes as Evidence; redact usernames if required.
  4. Optional: compare with lastb-tips / fail2ban-tips.
  5. Stop at literacy — no attack or unauthorized unlock cookbooks.

Practical notes for authorized labs

  • faillock is the PAM tally tool; fail2ban is typically network-facing — keep them distinct in binders.
  • --dir overrides exist on some distros; quote the path you actually used.
  • Never paste full tally directories from production into public notes.
  • Pair with chage-tips when aging and lockout both appear in a syllabus auth unit.
  • Label resets clearly — a lab reset is not a production unlock.
Which to pick
  • Prefer authorized, redacted, read-only Evidence.
  • Use lastb / fail2ban / pwck peer tip pages when the syllabus asks.
  • No exploit, crack, or unauthorized-access framing.

FAQ

What is a "faillock tip" page in BinBench framing?

A checklist for reading authorized PAM faillock tallies on hosts you own or were given syllabus access to — not a cookbook for unlocking or attacking foreign accounts.

How does this relate to lastb-tips / fail2ban-tips?

Those pages cover btmp failed-login history and network ban jails. This page zooms on a general faillock tip checklist — it does not overwrite those pages.

Can I reset faillock on hosts I do not own?

No. Authorization first. BinBench will not publish unauthorized unlock recipes against foreign accounts.

Does this teach exploit / bypass PoCs via faillock?

No. Mentions of exploit/bypass appear only as refusals. Authorized literacy only — prefer lab VMs and redacted samples.

Does this teach credential theft via faillock?

No. faillock shows failure counts, not passwords — still redact usernames before sharing excerpts.
