SSH, rsync & dependencies¶

Cannot connect¶

1. Hostname/IP and port correct?
2. Firewall allows SSH from PiHerder host?
3. Test connection on SSH access panel.
4. Key deployed? Password only for bootstrap.

Key deploy fails¶

• Password session required if key not yet installed.
• authorized_keys permissions on remote (~/.ssh 700, file 600).
• SELinux/AppArmor rare edge cases on some distros.

Backups: permission denied / rsync¶

• Non-root: need sudo -n rsync (passwordless) for protected paths.
• Root/HAOS: plain rsync path auto-detected.
• Path policy may deny the source — check allow/deny on Backups page.

Docker commands fail after least-priv¶

• User in docker group? re-login / new session.
• Docker base dir absolute path + Option B ACL if stacks under another home.
• ~/docker expands to wrong home after username switch.

Dependency chips red¶

SSH access → Check dependencies (or Test connection) — install missing packages on the host yourself (PiHerder does not auto-install).
