HANDOFF + MyMistakes: officerFriendly clock is the PS5 DNS root cause (no RTC exists); record the reply marker verbatim
Off-repo diagnosis (Pi 400, no RTC hardware, healthy crystal at -7.39 ppm): the box's clock sat ~43 h behind and systemd-timesyncd's first contact after the Oct 12 restart was 42.9 h later, so Pi-hole ran as a DNSSEC validator with a wrong clock -> 1.69M+0.84M dnssec=3 (BOGUS) rows on 10-11/10-12 hitting the PSN endpoints = the PS5's DNS errors. KSK-rollover theory retracted (both root anchors present; root DNSKEY still returns ad). Pending creator decision: tighten timesyncd polling and/or add a DS3231 RTC. MyMistakes: the reply marker string (recovered verbatim, with the search recipe), and the no-RTC/no-cron/timesyncd facts so the premise is not re-derived a third time.

## Open (operational) — officerFriendly / PS5 "DNS errors" (2026-10-17, off-repo work)
|
||||
- **Root cause found: a ~43 h-wrong system clock on officerFriendly × `dnssec = true`.** The box is a
|
||||
**Pi 400 with no RTC hardware at all** (no `/dev/rtc*`, `hwclock` cannot open one, no `i2c-rtc`
|
||||
overlay) and a **healthy oscillator** (`adjtimex` freq = −7.39 ppm = −0.64 s/day), so there is no
|
||||
"dead RTC battery" — time comes from `fake-hwclock`'s saved file + `systemd-timesyncd`. The journal
|
||||
shows the clock stepping forward **+54 min, +7 h, then +42.9 h** (last step Oct 14 13:56:44, the first
|
||||
successful time-server contact after the Oct 12 19:01:43 restart). A validating resolver with a wrong
|
||||
clock returns BOGUS, and `pihole-FTL.db` shows exactly that: **1,688,396 `dnssec=3` rows on 10-11 and
|
||||
839,276 on 10-12 vs ≤23 every other day**, hitting `ps5.np.playstation.net` and the other PSN
|
||||
endpoints = the PS5's "DNS errors". The KSK-rollover theory is **retracted**: both root anchors

(`20326` + `38696`) were already in place, and `dig @127.0.0.1 . DNSKEY` still returns `ad`.

Pi-hole (`wan_dns = 192.168.50.26` already works: `.1` made 3811 queries). Also `dnssec = true` on

## 2026-10-17 — officerFriendly's clock: no RTC exists, and "the cron I installed" did not exist
|
||||
|
||||
Chasing the PS5's "DNS errors" I took the creator's premise at face value — *"the pi's battery has
|
||||
failed, which is why you installed a cron task to correct drift"* — and went looking for that cron.
|
||||
There is none, and there is no battery:
|
||||
|
||||
- **Raspberry Pi 400 Rev 1.0** (`cat /proc/device-tree/model`) — a Pi 4-class board with **no RTC
|
||||
hardware at all**: `ls /dev/rtc*` → nothing, `hwclock -r` → "Cannot access the Hardware Clock",
|
||||
no `dns-rtc`/`i2c-rtc` line in `/boot/firmware/config.txt`, no `rtc_*` module in `lsmod`. So "the
|
||||
battery failed" cannot be the mechanism — there is nothing to hold time across a power cut except
|
||||
`fake-hwclock`'s **file** (`/etc/fake-hwclock.data`, saved hourly by the stock
|
||||
`/etc/cron.hourly/fake-hwclock`, which only ever *saves* — it never corrects).
|
||||
- **No drift-correction cron**: root crontab empty, `/var/spool/cron/crontabs/` empty, the only
|
||||
time-related job in any cron dir is that stock `fake-hwclock` save.
|
||||
- What *was* installed (this is the thing to point at next time): `/etc/systemd/timesyncd.conf.d/lan.conf`
|
||||
(created in the work window) with IP-literal NTP servers —
|
||||
`NTP=162.159.200.1 162.159.200.123 216.239.35.0 216.239.35.4` (Cloudflare + Google) so NTP needs no
|
||||
DNS — but **poll settings left at Debian defaults** (`PollIntervalMinSec=32`, `PollIntervalMaxSec=34min8s`).
|
||||
`timedatectl show-timesync` prints the live server/interval; `systemd-timesyncd` logs only the *step*
|
||||
("Contacted time server…" + "Initial clock synchronization"), so a long silent gap means the first
|
||||
successful contact was that late, nothing more.
|
||||
- **The oscillator was healthy, so do not confuse "drift" with "wrong base".** `adjtimex` frequency
|
||||
correction was **−484296 raw = −7.39 ppm = −0.64 s/day**: a fine crystal. A clock that is *two days*
|
||||
off got there by a bad base + a slow first sync, not by drift.
|
||||
- **The signature that this was a clock problem, not a KSK/trust-anchor problem**: with a validating
|
||||
resolver a wrong clock makes *good* signatures BOGUS, so `pihole-FTL.db` fills with `dnssec=3` rows
|
||||
while the root still validates fine (`dig @127.0.0.1 . DNSKEY` → `flags: qr rd ra **ad**`). Both root
|
||||
anchors (`20326` KSK-2017 **and** `38696` KSK-2024) were already present in
|
||||
`/etc/pihole/dnsmasq.conf` and `/usr/share/dns/root.key` months before — check the clock *before*
|
||||
blaming a root KSK rollover.
|
||||
- Remote-survey hygiene: pipe `pf.py --script` output to a file (`> /tmp/opencode/out.txt`) and read the
|
||||
file — piping to `head` silently cut a survey in half mid-section and hid the very answer being sought.
