SSH and logs

The pedalboard runs an SSH server. There is no password login: only keys.

Log in

Put your public key (for instance ~/.ssh/id_ed25519.pub) in a file named authorized_keys on the card’s first partition, from any computer. Several keys can go in the file, one per line.
Start the pedalboard. The keys are copied at each boot; deleting the file revokes them.
Log in as root, at the address shown in Settings → Wi-Fi (Ethernet included):

ssh root@192.168.1.42

Logs and version

tail -f /var/log/messages     # audio server, app, storage
cat /etc/pedalboard-release   # version of the image
pedalboard-update status      # system slots and the last update

Logs are kept in memory: they start again at each boot. The app writes to syslog one line per event, with what varies as name=value fields, for instance WARN ... Preset skipped path=/data/pedalboard/presets/old.json error=.... Errors mean a feature is lost (no audio, a save failed), warnings that something was worked around (a file skipped, a retry):

grep -E "ERROR|WARN" /var/log/messages   # what went wrong since boot

pedalboard-report prints everything useful for a bug report in one go: versions and system slots, the settings in effect, the sound cards and how the audio server opened them, their mixer controls, the audio messages of the kernel, and the logs of the audio server and the app. It changes nothing.

Files

Your data lives in /data/pedalboard:

Folder	What it holds
`models/`	Neural captures and impulse responses, `Tone3000/` for downloads
`presets/`, `scenes/`	Presets and setlists
`rigs/`	Exported and imported rigs (`.openrig` files)
`lv2/`	LV2 plugin bundles

Copy files with scp -O, then give them to the app:

scp -O -r "My Rig" root@192.168.1.42:/data/pedalboard/models/
ssh root@192.168.1.42 'chown -R pedalboard:pedalboard /data/pedalboard'

Back up

Before writing a new image to the card, which erases it, copy your data off:

ssh root@192.168.1.42 'tar -cf - -C /data pedalboard' > openrig-backup.tar

The backup includes your TONE3000 sign-in: keep it private.
