     2→
     3→**Date:** 2025-12-15
     4→**Project:** GuruRMM Agent Development
     5→**Status:** Working
     6→
     7→## Summary
     8→
     9→Implemented service installation for Linux (systemd) and Windows (SCM), network state collection with change detection, and added significant roadmap items for white-labeling and system tray features.
    10→
    11→## Work Completed
    12→
    13→### 1. Service Installation (Linux - systemd)
    14→
    15→**Commands:**
    16→- `sudo ./gururmm-agent install` - Copies to /usr/local/bin, creates config, enables service
    17→- `sudo ./gururmm-agent uninstall` - Stops, disables, removes service and binary
    18→- `sudo ./gururmm-agent start/stop` - Control the service
    19→
    20→**Features:**
    21→- Copies binary to `/usr/local/bin/gururmm-agent`
    22→- Creates config at `/etc/gururmm/agent.toml`
    23→- Unit file at `/etc/systemd/system/gururmm-agent.service`
    24→- `Restart=always` with 10-second delay (self-healing)
    25→- Security hardening: NoNewPrivileges, ProtectSystem=strict, ProtectHome=read-only, PrivateTmp
    26→- Logs to journald
    27→
    28→### 2. Service Installation (Windows - SCM)
    29→
    30→**Commands:**
    31→- `gururmm-agent.exe install` (Admin required)
    32→- `gururmm-agent.exe uninstall` (Admin required)
    33→- `gururmm-agent.exe start/stop`
    34→
    35→**Features:**
    36→- Copies to `C:\Program Files\GuruRMM\gururmm-agent.exe`
    37→- Creates config at `C:\ProgramData\GuruRMM\agent.toml`
    38→- Service name: `GuruRMMAgent`
    39→- Recovery: restart 3 times on failure (60-second delay each)
    40→- Auto-start on boot
    41→- Runs as LocalSystem
    42→
    43→### 3. Network State Collection
    44→
    45→**Data Collected:**
    46→```rust
    47→NetworkState {
    48→    timestamp: DateTime<Utc>,
    49→    interfaces: Vec<NetworkInterface>,  // name, mac, ipv4[], ipv6[]
    50→    state_hash: String,  // For change detection
    51→}
    52→```
    53→
    54→**Behavior:**
    55→- Sends initial state immediately after authentication
    56→- Checks for changes every 30 seconds
    57→- Only sends update when hash changes (interface add/remove, IP change)
    58→- Filters out loopback-only and link-local-only interfaces
    59→- WAN IP captured by server from connection source (no external API calls)
    60→
    61→**Added crate:** `local-ip-address = "0.6"` for cross-platform interface enumeration
    62→
    63→### 4. Feature Roadmap Additions
    64→
    65→Added to `docs/FEATURE_ROADMAP.md`:
    66→
    67→**Agent Updates (P1-P3):**
    68→- Built-in update handler (not shell script)
    69→- Server sends update command with version, URL, checksum
    70→- Download, verify SHA256, replace binary, restart
    71→- Rollback capability, staged rollouts
    72→
    73→**White-Labeling / Branding (P2-P3):**
    74→- Install-time: custom service name, display name, install path
    75→- Runtime: server-managed branding config, logo/icon URL, support contact
    76→
    77→**System Tray / End-User Self-Service (P2):**
    78→- Windows tray icon, macOS menu bar
    79→- Built-in actions: System Info, Create Ticket, Screenshot to Ticket
    80→- Admin-definable custom actions (RestartService, RunCommand, OpenUrl)
    81→- Per-customer action sets, confirmation dialogs, elevation support
    82→
    83→## Binary Sizes

   103→```
   104→
   105→## Discussion Topics
   106→
   107→### Data Collection
   108→- Interval metrics: CPU, memory, disk, network throughput (every 30s)
   109→- Network state: LAN IPs, MACs, interface names (on connect + change)
   110→- WAN IP: Captured server-side from WebSocket connection
   111→
   112→### Agent Versioning & Updates
   113→- Agent already sends version in auth payload
   114→- Update mechanism: Server sends update command, agent handles internally
   115→- Not shell script based - built-in download, verify, replace, restart
   116→- Queued for implementation
   117→
   118→### White-Labeling Discussion
   119→- MSPs need branded agents (service name, display name, icon)
   120→- Options: compile-time, config-file, install-time params, server-managed
   121→- Decided: hybrid - install-time params + server-managed runtime config
   122→
   123→### System Tray Features
   124→- End-user self-service reduces helpdesk calls
   125→- Built-in: System Info, Create Ticket, Screenshot to Ticket
   126→- Admin-definable: Restart Spooler, Clear Temp, etc.
   127→- Server pushes menu config, agent caches locally
   128→
   129→## Queued Tasks
   130→
   131→1. **Agent Update Handler** - Built-in update mechanism
   132→2. **macOS launchd installer** - Service installation for macOS
   133→3. **Watchdog module** - Monitor and restart other services
   134→
