Rebinding vllm-chat was the expensive option: Petal, Gogobee and Open
WebUI all point at 127.0.0.1:8000, and Open WebUI keeps its endpoint in
its own database rather than in env, so moving the bind address meant
editing three consumers and reloading a 35B AWQ model. The socat unit
adds a second listener on the headscale address instead -- local callers
untouched, no downtime, and the only new exposure is on the VPN. Bound
to 100.64.0.2 specifically, never 0.0.0.0: the far end is a public host.
Verified: a grammar checkpoint from petal.parodia.dev returns real
suggestions in ~3s over the VPN.
Also documents two things found on millenia that were invisible from
outside it:
- Piper had been dead since the Jul 26 reboot, 26,800+ failed restarts,
with read-aloud silently falling back to browser Web Speech. An OS
upgrade moved /usr/bin/python3 from 3.13 to 3.14, and venv/bin/python3
is a symlink to the system interpreter, so lib/python3.13/site-packages
went invisible -- sys.path had no site-packages at all. Recreating the
venv lands Piper 1.6.0, which is what TTS_PATH exists for.
- The canonical instance has no automated backup (newest snapshot a
month old) and runs unsupervised with PPID 1. Both written down; the
backup one is pending the encryption-at-rest decision.
Backups on the VPS now ride parodia-backup (age-encrypted, offsite, S3),
using VACUUM INTO rather than that script's iterdump helper -- iterdump
does not reproduce an FTS5 virtual table, so a restore would have come
back with cross-document search silently missing.
