Bug: raw ed25519.PublicKey bytes were stored directly instead of
OpenSSH authorized-key format (ssh-ed25519 AAAA... label).
Fixes:
- internal/sshmanager/fingerprint.go: GenerateKeyPair now uses
ssh.NewPublicKey + ssh.MarshalAuthorizedKey
- internal/sshmanager/keys.go: EnsureServerKey uses same fix; also
regenerates .pub file from private key if stored value is corrupt
- internal/sshmanager/fingerprint.go: add MarshalED25519PublicKey,
PublicKeyFromPrivateKeyFile, RegeneratePublicKeyFromPrivateKeyFile
- internal/models/sshkey.go: add UpdatePublicKey
- internal/api/handlers_sshkeys.go: List+Get recover existing DB
records with corrupt public keys by regenerating from private key
file and updating the DB
Also adds golang.org/x/crypto/ssh dependency via go mod tidy.
Full-stack Go monolith with embedded React frontend for orchestrating
rsync-over-SSH file synchronization with Wake-on-LAN support.
Features:
- JWT auth (HS256) with bcrypt password hashing
- CRUD for machines (with WoL config) and sync_pairs
- Ed25519 SSH key generation and known_hosts management
- WoL magic packet sender + TCP-connect waiter with backoff
- Sync engine: rsync subprocess, per-pair job queue, progress parsing
- Homebrew cron parser for scheduled syncs
- SSE stream for live job status (queued/waking_up/running/success/failed)
- React+TS+Vite+Tailwind SPA embedded via embed.FS
- Debian packaging with systemd unit, postinst/prerm/postrm
Tech stack:
- Go 1.22+ (CGO_ENABLED=0, pure SQLite via modernc.org/sqlite)
- chi router for HTTP API
- TypeScript + React 18 + Tailwind CSS frontend
- Cross-compiled to Linux amd64 for Proxmox LXC deployment
Tests: wol (MAC parsing, magic packet), syncengine/queue, scheduler/cron
