- New Last Seen column showing last_seen_at timestamp per machine
- Status badges: online=green (success), offline=red (error), waking/pending=amber
- Update Machine interface with last_seen_at and created_at fields
Deploy-keys now only:
- Creates /var/lib/syncserver/ssh/keys on remote
- Uploads private keys of all other machines to that path
- Populates known_hosts with all other machine hosts
No longer touches authorized_keys or reads server public key.
- sshmanager/deploy.go: initialize DeployResult with empty slices
instead of nil to prevent null serialization in JSON
- Machines.tsx: use ?? [] fallback for messages and errors arrays
in deploy keys modal to handle null/undefined gracefully
- sshmanager/deploy.go: new DeployKeysToMachine function that uploads
private keys, populates known_hosts via ssh-keyscan, and adds server
pub key to authorized_keys on remote machines
- handlers_machines.go: new DeployKeys handler with auto-detection of
keys needed per sync pair (source->dest uploads dest key, dest->source
uploads source key)
- router.go: POST /machines/{id}/deploy-keys route
- client.ts: deployKeys() API method
- Machines.tsx: Deploy Keys button + modal with result display
Machine status probe on page load:
- POST /api/machines/refresh probes all machines in parallel (max 20 concurrent, 1.5s timeout)
- Updates DB status and broadcasts via SSE to all connected browser tabs
- Server-side throttle: ignores refresh requests within 10s
- Machines.tsx and Dashboard.tsx fire probe on mount
- Visual "Checking machine status..." indicator in Machines table
- MachineHandler now accepts *Engine for ProbeAllMachines access
Smart WoL: TCP pre-check before sending magic packet (3s timeout).
Machine status updates via SSE: online/offline tracked in DB and
broadcast to all connected browser tabs in real-time.
- Pre-check: if machine already reachable, skip WoL and mark online
- WoL path: send 3 magic packets, wait for SSH, mark online/offline
- Backend: setMachineStatus() helper + machine_status SSE event
- Frontend: subscribeMachineStatus() SSE helper for Machines + Dashboard
- IsReachable() helper in wol package for TCP reachability checks
Fix Wake-on-LAN: set SO_BROADCAST on UDP socket, send 3 magic packets,
expose broadcast_addr and wake timeout fields in UI, add Test Wake endpoint,
surface send errors in job status, bump default wake timeout to 180s.
Frontend:
- JobDetail loadLogs: fallback to [] when API returns null
- JobDetail loadJob: pairs ?? [] guard on /api/sync-pairs 500
- JobHistory: Array.isArray guard on job list response
- api client: return undefined for null body instead of throwing
Backend:
- handlers_jobs GetLog: return [] instead of null when no log rows
- router: custom recoverer middleware that logs panics to slog
with full stack trace, method, and path
- Radix SelectTrigger composes its children via Slot internally
- Having both {children} and <Icon asChild> caused "Slot failed to slot onto its children"
- Use Radix default Icon instead (rendered automatically)
- Separate render paths: asChild uses Slot directly, normal uses button
- Fixes "Slot failed to slot onto its children" runtime error
- Slot now always receives exactly one child (the Link element)
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
