Addresses user concern about technical debt: detection code exists only
to handle migration from SSH-in-container to proxy architecture, not to
serve functional purpose of the application.
Changes:
- Add PULSE_LEGACY_DETECTION env var to disable detection without redeployment
- Add explicit removal criteria: v5.0 or <1% detection rate for 30+ days
- Mark all detection code with "MIGRATION SCAFFOLDING" warnings
- Create MIGRATION_SCAFFOLDING.md to track temporary code across codebase
- Document removal instructions for when migration period ends
Backend:
- internal/api/router.go: detectLegacySSH() checks env var and has removal plan
- internal/api/types.go: HealthResponse fields documented as temporary
Frontend:
- src/components/LegacySSHBanner.tsx: Component marked with removal criteria
- src/App.tsx: Banner integration (will be removed with component)
This approach balances user safety during migration (auto-detection catches
rushed admins who skip changelogs) with long-term code cleanliness (explicit
removal plan prevents indefinite technical debt).
Added automatic detection to alert users when they're using the old
SSH-in-container method for temperature monitoring so they can upgrade
to the secure proxy architecture.
**Detection Logic:**
- Checks if Pulse is running in a container (Docker or LXC)
- Checks if SSH keys exist in data directory (/etc/pulse/.ssh)
- Checks if pulse-sensor-proxy socket is NOT available
- Sets legacySSHDetected and recommendProxyUpgrade flags in health endpoint
**API Changes:**
- Added fields to HealthResponse:
- legacySSHDetected: true when old method detected
- recommendProxyUpgrade: true when upgrade is recommended
- proxyInstallScriptAvailable: always true
**Use Case:**
Users who set up temperature monitoring before the proxy feature
won't know they should upgrade. This detection allows the frontend
to show a banner prompting them to re-run the setup script to
migrate to the secure proxy architecture.
**Frontend Integration (to be added):**
Frontend can poll /api/health and show a dismissible banner similar
to UpdateBanner when legacySSHDetected is true, with a button to
view the setup script.
Addresses #123
Codex caught an edge case in the authorized_keys removal logic:
**Problem:**
When authorized_keys contains ONLY pulse-managed keys, `grep -vF` returns
exit code 1 (no lines matched the inverse filter). The previous code only
executed the rewrite on exit 0, leaving managed keys in place when they
should have been removed.
**Solution:**
- Capture grep exit code explicitly
- Treat both exit 0 (lines remain) and exit 1 (all removed) as success
- Only treat exit codes > 1 as actual errors
- Properly handles the "remove all keys" scenario
This ensures complete removal works even when the file contains nothing
but Pulse-managed entries.
Addresses #123
Fixed three remaining issues from Codex's final review:
**1. nullglob State Management (line 3124)**
- Replaced shopt -s/u nullglob with compgen -G check
- Prevents changing global shell behavior that could affect later globs
- More explicit and safer pattern matching
**2. authorized_keys Permission Preservation (lines 3116-3117)**
- Now uses chmod/chown --reference to preserve original ownership/perms
- Falls back gracefully if --reference not available
- Proper cleanup on mv failure to prevent temp file leaks
- Aborts atomically if operations fail, leaving original untouched
**3. Multi-Address Container Detection (lines 3750-3761)**
- Iterates over ALL IPs from hostname -I, not just first one
- Handles dual-stack (IPv4 + IPv6) and multi-IP containers
- Uses break 2 to exit both loops when match found
- Prevents false negatives when Pulse IP is not the first address
All operations now handle edge cases properly: non-root accounts,
dual-stack networking, empty directories, and partial failures.
Addresses #123
Applied Codex's security and reliability recommendations:
**SSH Key Safety:**
- Added "pulse-managed-key" comment marker to all SSH keys
- Removal now targets only marked keys (prevents deleting operator keys)
- Uses atomic file replacement via mktemp for authorized_keys edits
**Idempotency Improvements:**
- LXC config glob now uses nullglob to handle empty directories
- pveum token removal handles missing users gracefully (|| printf '')
- All systemctl operations wrapped with || true for non-systemd hosts
- sed operations in loops protected with || true
**Container Detection:**
- Validates container is running before IP check (pct status)
- Confirms container exists with pct config before proceeding
- Uses printf '' instead of || true for command substitution
- Handles IPv6 and multi-IP scenarios more reliably
**Network Operations:**
- curl now uses --fail --show-error --silent --location
- Error messages visible to users instead of silenced
- Better diagnostics when download fails
**Migration Safety:**
- Verifies pulse-sensor-proxy service is active before key removal
- Fallback check for binary existence if systemd unavailable
- Preserves legacy SSH keys if proxy not confirmed healthy
- Clear messaging about deferred cleanup
All cleanup operations are now fully idempotent and safe for
repeated execution, even on partially-configured hosts.
Addresses #123
Added a main menu at the beginning of the PVE setup script that gives users three options:
[I]nstall - Continue with normal setup (default)
[R]emove All - Complete uninstall of all Pulse components
[C]ancel - Exit without changes
The removal option comprehensively cleans up:
- pulse-sensor-proxy service, binary, and systemd unit
- pulse-sensor-proxy system user and data directories
- All SSH keys from authorized_keys (legacy and forced-command variants)
- LXC bind mounts from all container configs
- Pulse monitoring API tokens, user, and custom roles
This addresses user request for a clean removal path for everything
Pulse has installed on the host, including legacy components from
previous versions.
Made the setup and installation output more concise and reassuring for users. Less verbosity, clearer messaging.
**Setup script improvements:**
- Changed "Container Detection" → "Enhanced Security"
- Simplified prompts: "Enable secure proxy? [Y/n]"
- Cleaned up success messages: "✓ Secure proxy architecture enabled"
- Removed verbose status messages (node-by-node cleanup output)
- Only show essential information users need to see
**install-sensor-proxy.sh improvements:**
- Added --quiet flag to suppress verbose output
- In quiet mode, only shows: "✓ pulse-sensor-proxy installed and running"
- Full output still available when run manually
- Removed redundant "Installation complete!" banners
- Cleaner legacy key cleanup messaging
**Result:**
Users see a clean, professional installation flow that builds confidence. Technical details are hidden unless needed. Messages are clear and reassuring rather than verbose.
When pulse-sensor-proxy is installed, automatically remove old SSH keys that were stored in the container for security.
Changes:
**install-sensor-proxy.sh:**
- Checks container for SSH private keys (id_rsa, id_ed25519, etc.)
- Removes any found keys from container
- Warns user that legacy keys were cleaned up
- Explains proxy now handles SSH
**Setup script (config_handlers.go):**
- After successful proxy install, removes old SSH keys from all cluster nodes
- Cleans up authorized_keys entries that match the old container-based key
- Keeps only proxy-managed keys (pulse-sensor-proxy comment)
This provides a clean migration path from the old direct-SSH method to the secure proxy architecture. Users upgrading from pre-v4.24 versions get automatic cleanup of insecure container-stored keys.
The setup script now automatically detects when Pulse is running in an LXC container and offers to install pulse-sensor-proxy on the host for enhanced security.
What happens:
1. After temperature monitoring is configured
2. Script detects Pulse IP and finds matching container
3. Prompts: "Install pulse-sensor-proxy for container X? [Y/n]"
4. Downloads and runs install-sensor-proxy.sh automatically
5. Falls back gracefully if proxy install fails
Benefits:
- One-command setup for users (no manual proxy installation)
- SSH keys stay on host (not in container)
- Containerized Pulse gets the secure architecture automatically
- Native installs unaffected (still use direct SSH)
This solves the UX problem where users had to manually run install-sensor-proxy.sh as a separate step.
The name "temp-proxy" implied a temporary or incomplete implementation. The new name better reflects its purpose as a secure sensor data bridge for containerized Pulse deployments.
Changes:
- Renamed cmd/pulse-temp-proxy/ to cmd/pulse-sensor-proxy/
- Updated all path constants and binary references
- Renamed environment variables: PULSE_TEMP_PROXY_* to PULSE_SENSOR_PROXY_*
- Updated systemd service and service account name
- Updated installation, rotation, and build scripts
- Renamed hardening documentation
- Maintained backward compatibility for key removal during upgrades
Replaced outdated security warnings with accurate information about
the pulse-temp-proxy architecture:
- Removed scary 'legacy feature' and 'compromised container' warnings
- Explains secure proxy architecture for containerized deployments
- Notes that SSH keys are stored on Proxmox host (not in container)
- Clarifies container compromise does not expose credentials
- Includes information for both containerized and native installs
- More factual and less alarmist tone
The old message implied temperature monitoring was insecure for
containers, which is no longer true with pulse-temp-proxy.
Related to #528
The setup script generator was passing sshPublicKey twice but only
using it once, causing a Go fmt.Sprintf formatting error that leaked
into the generated bash script as '%!(EXTRA string=...)'.
This resulted in bash syntax errors when running the setup script.
Fixes#528
When Pulse runs in a container (LXC/Docker), the setup script would claim
temperature monitoring was enabled on cluster nodes, but Pulse couldn't
actually SSH to them. The script ran on the Proxmox host which could SSH
fine, but didn't verify connectivity from Pulse itself.
Changes:
- Added /api/system/verify-temperature-ssh endpoint that tests SSH from Pulse
- Setup script now calls this endpoint after configuring cluster nodes
- Detects when Pulse is containerized and provides ProxyJump config instructions
- Shows clear success/failure status for each node
Addresses #528
Add no-cache headers to both the install script and agent binary download endpoints to prevent browsers and curl from serving stale cached versions. This ensures users always get the latest install script with URL normalization fixes for trailing slash issues.
Fixes#528
The PUT /api/config/nodes/{id} endpoint was corrupting node configurations
when making partial updates (e.g., updating just monitorPhysicalDisks):
- Authentication fields (tokenName, tokenValue, password) were being cleared
when updating unrelated settings
- Name field was being blanked when not included in request
- Monitor* boolean fields were defaulting to false
Changes:
- Only update name field if explicitly provided in request
- Only switch authentication method when auth fields are explicitly provided
- Preserve existing auth credentials on non-auth updates
- Applied fix to all node types (PVE, PBS, PMG)
Also enables physical disk monitoring by default (opt-out instead of opt-in)
and preserves disk data between polling intervals.
Backend was loading system settings from disk on every HTTP request
causing massive log spam and UI responsiveness issues. System settings
are now cached at startup and reloaded only when updated.
Also fixed tab cursor showing text cursor instead of pointer cursor.
Changes:
- Cache system settings in Router struct with mutex protection
- Load settings once at startup instead of on every request
- Add reloadSystemSettings() method to refresh cache when settings change
- Hook up cache reload in config handlers after successful save
- Add cursor-pointer to tab CSS classes for proper hover cursor
- Auto-detect update channel from current version when config is empty
(RC users automatically get RC updates, stable users get stable)
- Add background update checker that runs on startup and hourly
- Add GetCachedUpdateInfo() method to return cached update info
- Update /api/version endpoint to include updateAvailable from cache
- Fixes issue where RC users on rc.4 weren't seeing rc.5 updates
This ensures RC testers continue receiving RC notifications while
stable users stay on the stable channel, all without explicit config.
- Fix update history using hardcoded /var/lib/pulse instead of configured data dir
- Skip mock.env watching in Docker environments to avoid 'no such file' errors
Fixes issue #529
Update History Path:
- Modified NewUpdateHandlers to accept dataDir parameter
- Pass r.config.DataPath from router (honors PULSE_DATA_DIR=/data in Docker)
- Maintains backward compatibility with default /var/lib/pulse when empty
Mock Env Watcher:
- Check PULSE_DOCKER env var and skip mock.env watching if true
- Only watch /opt/pulse/mock.env if directory exists (not in containers)
- Guard all mock.env operations to prevent errors when path is empty
- Clean up log messages to only show mock_env_path when actually watching
- Strip trailing slash from PULSE_URL in install script to prevent double-slash URLs
- Add path normalization in router for defense-in-depth on public endpoint matching
- Fixes issue #528 where users copying URLs with trailing slashes got 401 errors
The install script now normalizes PULSE_URL with ${PULSE_URL%/} before concatenating
with /download/pulse-docker-agent, preventing https://example.com//download URLs.
The router normalization provides additional resilience for path matching, though the
existing path traversal check already blocks double slashes at ServeHTTP level.
This commit addresses 6 critical security and UX issues in Docker agent
token handling identified through code review:
**High Priority Fixes:**
1. Fix stale token in command preview - Changed DockerAgents to use
getInstallCommandTemplate() that always returns placeholder, allowing
CommandBuilder to handle all token substitution reactively. Command
preview now updates live as user types.
2. Fix misleading "multiple tokens" messaging - Updated token generation
modal to accurately reflect single-token backend model with red warning:
"This will immediately invalidate your existing token". Prevents operators
from unknowingly breaking active Docker agents.
3. Close proxy auth bypass vulnerability - Both HandleRegenerateAPIToken
and HandleValidateAPIToken now explicitly reject requests when proxy auth
is configured but validation fails (returns 401). Prevents unauthenticated
access when proxy auth is enabled.
**Medium Priority Fixes:**
4. Disable buttons when no stored token - "Use This Token" and "Copy" buttons
now properly disabled with contextual tooltips when browser hasn't saved
a token, eliminating confusing silent no-ops.
5. Improve frontend error handling - Token validation now distinguishes
between authentication errors (401/403), rate limiting (429), network
failures, and actual invalid tokens. No longer mislabels auth failures
as "invalid token".
**Low Priority Fixes:**
6. Add authentication to validate-token endpoint - Endpoint now requires
admin authentication (same as regenerate-token), preventing unauthenticated
token guessing oracle despite rate limiting.
**New Component:**
- CommandBuilder.tsx: Interactive command builder with live preview,
state-based visual cues, inline token generation, and validation
**Security Impact:**
- Closes unauthenticated validation surface
- Enforces proper proxy auth gating
- Prevents accidental exposure of security model
- Rate limiting maintained (10 attempts/min)
**UX Impact:**
- Clear, accurate error messages
- Live-updating command preview
- Contextual token management
- Disabled states prevent confusion
Reviewed and verified by both Claude Code and Codex with no regressions found.
Wire up the adapter-based update system to HTTP API:
**Enhanced UpdateHandlers:**
- Initialize UpdateHistory and UpdaterRegistry
- Register all deployment adapters (systemd, proxmoxve, docker, aur)
- Handlers now have access to history and updater registry
**New API Endpoints:**
- GET /api/updates/plan?version=X - Get update plan for deployment
* Returns canAutoUpdate, instructions, prerequisites, estimated time
* Deployment-specific based on detected type
- GET /api/updates/history?limit=N&status=X - List update history
* Supports filtering by status (success/failed/in_progress)
* Returns audit log entries with full metadata
- GET /api/updates/history/entry?id=X - Get specific history entry
* Retrieve detailed information about past update
**Existing Endpoints Still Work:**
- GET /api/updates/check - Check for available updates
- POST /api/updates/apply - Apply update (legacy manager)
- GET /api/updates/status - Get current update status
The system now supports both:
- Legacy update flow (existing install.sh wrapper in manager.go)
- New adapter-based flow (prepared for frontend integration)
Next: Frontend components to consume new endpoints.

spam distribution analysis, and quarantine monitoring. Includes full discovery
support and UI consistency improvements across all Proxmox products.
Backend:
- Add pkg/pmg package with complete API client for PMG operations
- Implement mail statistics collection (inbound/outbound, spam, virus, bounces)
- Add queue depth monitoring (active, deferred, hold, incoming queues)
- Support spam score distribution and quarantine totals
- Add PMG-specific discovery logic to differentiate from PVE on port 8006
- Extend mock data generator with realistic PMG instances and metrics
- Add PMG node configuration support in config system
Frontend:
- Create MailGateway.tsx component with detailed PMG dashboard
- Display mail flow statistics with time-series charts
- Show queue depth with color-coded warnings (>50 messages or >30min age)
- Add spam distribution histogram and quarantine status
- Support cluster node status with individual queue monitoring
- Add PMG to network discovery with purple branding and mail icon
- Implement conditional navigation (hide PMG tab when no instances configured)
- Standardize discovery UI controls across PVE/PBS/PMG settings pages
API:
- Add /api/config/pmg endpoints for node configuration
- Support PMG-specific monitoring toggles (mail stats, queues, quarantine)
- Extend system settings with PMG configuration options
Discovery:
- Detect PMG vs PVE on shared port 8006 using /api2/json/statistics/mail endpoint
- Return 'pmg' type for mail gateway servers in discovery results

This completes ecosystem monitoring support for all three Proxmox products:
Proxmox VE, Proxmox Backup Server, and Proxmox Mail Gateway.
Add support for Authorization: Bearer <token> header as a fallback
for environments that strip custom headers like X-API-Token. Docker
agent now sends both headers for maximum compatibility.
Implements comprehensive Docker monitoring with a dedicated agent that collects
container metrics and reports them to the main Pulse server. Adds Docker-specific
alert rules and threshold management with a redesigned UI.
Backend changes:
- Add Docker agent binary with container metrics collection
- Implement Docker host and container models with CPU/memory tracking
- Add Docker-specific alert types (offline, state, health)
- Extend threshold system to support Docker resources
- Add WebSocket message types for Docker agent communication
- Implement Docker agent API endpoints for registration and metrics
Frontend changes:
- Add Docker monitoring page with host/container views
- Add Docker agent settings panel for configuration
- Reorganize thresholds page with Proxmox/Docker tabs
- Add Docker-specific alert threshold management
- Improve layout consistency with vertical stacking
- Fix defensive null checks and TypeScript errors
This change enables monitoring of Docker containers across multiple hosts
with the same alerting and threshold capabilities as Proxmox resources.
Improve performance when serving /api/state in mock mode by optimizing
alert handling and JSON serialization.
Changes:
- Add UpdateAlertSnapshots() to cache alerts without blocking
- Use lazy population of alert snapshots to avoid lock contention
- Switch to json.Marshal for better performance with large payloads
- Add debug logging to track /api/state performance
- Simplify GetState() logic in mock mode
Performance improvements:
- Eliminates alert manager lock during /api/state requests
- Reduces JSON encoding overhead for large mock datasets
- Ensures sub-second response times even with 7 nodes and 90+ guests
Testing:
- Mock mode returns state instantly without blocking
- Alert snapshots populate correctly on first request
- Debug logs confirm fast execution path

Addresses #327 - Users behind reverse proxies (Traefik, nginx, etc) were
experiencing redirect loop issues because the redirect URL was being built
with http:// instead of https:// when X-Forwarded-Proto was set.
Changes:
- Build OIDC redirect URL dynamically from each request instead of at startup
- Respect X-Forwarded-Proto and X-Forwarded-Host headers from reverse proxies
- Update UI help text to clarify auto-detection behavior
- Add debug logging to show how redirect URL is constructed
When redirect URL is not explicitly configured, Pulse now builds it from
the incoming request headers, properly detecting HTTPS when behind a proxy.

Changed from scary warnings to confident, reassuring tone:
Before:
- "⚠️ IMPORTANT: This grants SSH access..."
- Emphasized risks and compromise scenarios
- Made users feel unsafe enabling the feature
After:
- "Works just like Ansible, Saltstack, etc."
- Emphasizes this is industry-standard approach
- Compares to trusted automation tools
- Focuses on what it does, not what could go wrong
- Still transparent about security model
- Removes duplicate/contradictory sections
The feature is secure and follows best practices. The messaging should
reflect confidence in the design while still being transparent.
Users should feel good about enabling it, not scared.
- Make it clear SSH setup is OPTIONAL
- Explain security model upfront before user commits
- Detail exactly what access is being granted (root SSH, sensors only)
- Warn users to only proceed if they trust Pulse server
- Better differentiate public vs private keys
- Show exactly where the key is stored
- Explain how to revoke access
- Add comprehensive security documentation
- Include advanced option for command restrictions in authorized_keys
- Add risk assessment and best practices
This ensures users make informed decisions about SSH access to their
critical Proxmox infrastructure.
- Prompts user to set up SSH access during auto-setup
- Guides user to paste their Pulse server's public key
- Adds key to /root/.ssh/authorized_keys
- Installs lm-sensors automatically
- Runs sensors-detect --auto for proper sensor detection
- Optional: user can skip and set up later manually
- Includes validation of SSH key format
- Shows clear instructions for manual setup if skipped
This ensures temperature monitoring works out-of-the-box for users
who run the auto-setup script.
