w tips — authorized logged-in session literacy
w helps authorized labs sample logged-in session literacy on hosts they own. Pair with who-tips, lastlog-tips, login-tips, lastb-tips, id-tips. Prefer lab VMs — never enumerate sessions on foreign hosts without permission.

Tip checklist (authorized only)
- Confirm you may run
won the lab host (syllabus box you own or were given access to). - Prefer documenting who / why / ticket before collecting session Evidence.
- Record short factual notes; quote short Evidence (user, tty, idle, what — never passwords).
- Optional: utmp-style listing → who-tips.
- Optional: last-login DB → lastlog-tips.
- Optional: failed-login tallies → lastb-tips.
- Redact usernames/hostnames before Evidence leaves the lab binder.
- Stop at literacy — no attack or unauthorized session-stalking cookbooks.
Allowed framing
- Classroom labs reviewing
wcolumns on authorized hosts. - Binding short factual notes as Evidence (user/tty/idle/what only — no secrets).
- Documenting expected vs observed session counts for authorized inventory notes.
- Comparing w ↔ who / lastlog / login peer tip pages under one binder.
- Testing
w -h/w -istyle flags when the syllabus authorizes that drill.
Scope we will not cover
- No crack/pirate/keygen via session tools.
- No intentional stalking or unauthorized enumeration against foreign hosts.
- No secret-theft or credential dumping against hosts you do not own.
- No cookbooks that weaponize idle/what fields against other users without authorization.
Beginner path (authorized only)
- Obtain one syllabus-approved lab host with procps-ng (or equivalent) installed.
- Run
w(orw -h); quote 1–2 redacted rows as Evidence. - Optional: pair utmp listing with who-tips; last-login with lastlog-tips.
- Optional: identity literacy with id-tips.
- Stop at literacy — no attack or unauthorized session-enumeration cookbooks.
Practical notes for authorized labs
USER/TTY/FROM/LOGIN@/IDLE/WHATcolumns are binder-friendly when redacted.- Prefer lab accounts with known sessions so Evidence stays reproducible.
- Never paste full
FROMIP lists into public binders — redact to lab labels. - Pair with login-tips when reviewing how sessions are established.
- Label lab-only noisy sessions clearly so they are not mistaken for production posture.
- If
wis missing, install via the distro package manager the syllabus names — do not pull random binaries.
FAQ-aligned refusals (quick)
- Foreign-host session stalking → refuse.
- Sharing unredacted user/IP dumps in public binders → refuse.
- Attack cookbooks via w → refuse.
- Prefer authorized, redacted, secret-free Evidence.
- Use who / lastlog / login peer tip pages when the syllabus asks.
- No crack or unauthorized-access framing.

FAQ
What is a "w tip" page in BinBench framing?
A checklist for reading authorized logged-in session Evidence (w output) on hosts you own or were given syllabus access to — not a cookbook for stalking users on foreign servers.
How does this relate to who-tips / lastlog-tips / login-tips?
who-tips covers utmp-style who listings; lastlog-tips covers last-login DB; login-tips covers login-session literacy. This page zooms on a general w tip checklist — it does not overwrite those pages.
Can I run w against hosts I do not own?
No. Authorization first. BinBench will not publish unauthorized session enumeration against foreign hosts.
Does this teach attack PoCs via w?
No. Mentions of attack/bypass appear only as refusals. Authorized literacy only — prefer lab VMs and redacted samples.
Does this teach secret theft via w?
No. Never paste passwords, tokens, or full home-directory dumps into notes. Redact usernames and hostnames when Evidence leaves the lab.
