df inode tips — authorized inode literacy
For legal, authorized and educational use only. Only analyze software you own or have written permission to examine.
Quick answer
df -i helps authorized labs sample inode usage on hosts they own. Pair with df-disk-tips, du-disk-usage-tips, and ncdu-scan-tips.

Tip checklist (authorized only)
- Confirm you may sample filesystems on the host (lab VM / your server / courseware).
- Prefer
df -ih(human + inodes) short snapshots over endless loops. - Record filesystem, Inodes, IUsed, IFree, IUse% you actually see.
- Quote a few rows; avoid dumping every obscure mount on busy hosts.
- If block space (not inodes) is the question, cross-check df-disk-tips.
- Optional: directory sizes → du-disk-usage-tips; interactive → ncdu-scan-tips.
- Optional: open files → lsof-open-tips; Mem/Swap → free-disk-tips.
- Redact mount points, volume labels, and sensitive paths before sharing.
Allowed framing
- Classroom labs diagnosing "disk not full but create fails" on trees you own.
- Binding filesystem + IUse% notes as Evidence.
- Documenting "inode-full / df -i unavailable / remote FS limits" as valid lab outcomes.
- Comparing df -i ↔ df space / du / ncdu under one binder.
Scope we will not cover
- No crack/pirate/keygen via df.
- No persistence / unauthorized-access / bypass PoCs via df.
- No credential-theft via mount or fstab dumps.
- No intentional inode-exhaustion DoS against storage you do not own.
Beginner path (authorized only)
- Obtain one syllabus-approved lab VM you control.
- Run
df -ih; quote a few filesystem rows. - Bind filesystem + IUse% as Evidence; redact sensitive labels.
- Optional: compare block space with df-disk-tips.
- Stop at literacy — no unauthorized-access cookbooks.
Which to pick
- Prefer authorized, short, redacted Evidence.
- Use df-space / du / ncdu peers when the syllabus asks.
- No exploit, crack, or unauthorized-access framing.

FAQ
What is a "df inode tip" page in BinBench framing?
A checklist for inspecting authorized inode usage (df -i) on hosts you own — not a cookbook for filling or inspecting filesystems you do not control.
How does this relate to df-disk-tips?
df-disk-tips covers block/space usage. This page zooms on inode used/free Evidence — it does not overwrite that page.
Can I df -i 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 / inode-exhaustion DoS / bypass PoCs?
No. Mentions of exploit/bypass appear only as refusals. Authorized df -i literacy only.
Does this teach credential theft via mount dumps?
No. Redact mount points, volume labels, and paths that expose PII before sharing.
