Configuration Basics
Launch the Initial Setup Wizard to configure core settings: node IDs‚ authentication keys‚ storage paths. Create user accounts‚ assign roles‚ and set permissions. Adjust network interfaces and firewall rules to enable secure‚ seamless communication across the Hunter Node cluster. All settings saved instantly.
3.1 Initial Setup Wizard
Upon first launch‚ the Hunter Node Setup Wizard guides you through essential configuration steps. The wizard opens with a welcome screen‚ offering language selection and a brief overview of prerequisites. Next‚ you specify the node’s unique identifier and designate the primary data directory‚ ensuring sufficient disk space and correct permissions. The wizard then prompts for network configuration: you can choose between DHCP or static IP assignment‚ enter gateway‚ DNS servers‚ and subnet mask. After network settings‚ the wizard automatically detects available storage devices; you can select partitions for logs‚ cache‚ and user data‚ and set retention policies. Authentication is handled next: you create an admin password‚ generate an API key‚ and optionally integrate with an LDAP or OAuth provider for single sign‑on. The wizard also configures the built‑in web interface‚ allowing you to set the port‚ enable HTTPS‚ and upload a custom SSL certificate. Finally‚ the wizard summarizes all selections and performs a health check. If any component fails‚ error messages guide you to resolve issues before finalizing the setup. Once confirmed‚ the wizard writes configuration files to /etc/hunternode/config.yaml and starts core services. A confirmation screen displays the node’s status‚ uptime‚ and a QR code for quick mobile access. The wizard then closes‚ leaving the node ready for operation. The wizard’s interface is responsive‚ supporting desktop and mobile‚ with real time diagnostics monitoring!!!
3.2 User and Role Management
Hunter Node’s user and role management system is designed for granular control and auditability. From the web console‚ navigate to “Users & Roles” to view a table of existing accounts. Each row shows username‚ full name‚ email‚ last login‚ and assigned roles. To add a new user‚ click “Create User”‚ fill in the mandatory fields‚ and assign a password policy that enforces complexity and rotation. The wizard also offers the option to import users from an LDAP directory or CSV file; during import‚ you can map external attributes to internal fields. Roles are defined in the “Roles” tab‚ where you can create custom roles such as “Data Analyst”‚ “Node Operator”‚ or “Read‑Only Viewer”. Each role contains a set of permissions: read‚ write‚ execute‚ and delete on specific resource categories (nodes‚ tasks‚ logs). Permissions can be inherited from parent roles‚ allowing hierarchical structuring. For audit purposes‚ the system logs every role assignment change with timestamp‚ actor‚ and affected user. Password reset requests trigger an email workflow that includes a time‑limited token. Multi‑factor authentication (MFA) can be enforced per user or globally; supported methods include TOTP‚ U2F‚ and SMS. The “Session” page lists active sessions‚ with options to terminate or force logout. All changes are validated against the JSON schema before persisting. Finally‚ the “Role‑based API access” can be generated tied to a specific role‚ limiting the scope of operations that the key can perform. and many more.
3.3 Network and Connectivity Settings
Hunter Node’s networking panel supports IPv4‚ IPv6‚ and dual‑stack setups; Configure static IP‚ subnet‚ gateway‚ and DNS‚ or enable DHCP for automatic addressing. Secure all traffic with TLS by uploading a PEM bundle or generating a self‑signed certificate. The Ports section lists default service ports (HTTP 80‚ HTTPS 443‚ RPC 9000‚ SSH 22) and lets you override them with conflict checks. The network interface can be tuned with MTU settings and ARP cache options. Firewall rules integrate with iptables or firewalld‚ providing templates for common scenarios such as allowing inbound traffic from trusted CIDR blocks or blocking outbound connections to untrusted domains. Network Policies use Kubernetes‑style labels to enforce traffic segmentation between node groups; policies can be defined in YAML and applied via the API. For high‑availability‚ specify peer nodes and a health‑check interval; the system performs a rolling update of the network stack without downtime. Diagnostics run ping‚ traceroute‚ DNS resolution‚ and port scans‚ with results logged centrally and exportable as JSON or CSV. All changes trigger a validation engine that checks for overlapping CIDR ranges‚ port conflicts‚ and certificate expiration. If validation fails‚ the UI highlights the offending field and shows a detailed error. After successful validation‚ the system writes the configuration to persistent storage and reloads the networking stack atomically. Users can schedule changes to apply at a specified time‚ ensuring zero‑downtime updates; Additionally‚ the system supports VPN integration via OpenVPN or WireGuard‚ allowing secure remote access to node clusters. The audit trail records every change with timestamp‚ user‚ and diff‚ enabling traceability for compliance audits.
Daily Operations
Hunter Node’s daily operations schedule tasks‚ monitoring node health‚ and aggregating logs. The dashboard shows queue depth‚ worker limits‚ and alerts. Maintenance rotates logs‚ prunes snapshots verifies backups. Performance tuning adjusts cache and compression settings!
4.1 Managing Nodes and Tasks
Managing nodes and tasks in Hunter Node involves a combination of the interface‚ utilities‚ and scripts.
The console provides a view of each node’s status‚ including CPU usage‚ memory consumption‚ and throughput.
From the console you can start‚ stop‚ or restart individual nodes‚ and you can also scale the cluster by adding or removing nodes on the fly.
Each node reports a unique identifier and a set of tags that describe its role‚ location‚ and capabilities.
These tags are used by the scheduler to match tasks to the most suitable nodes‚ ensuring optimal load balancing and fault tolerance.
When a new task is submitted‚ the scheduler evaluates a task’s resource requirements‚ priority level‚ and dependency graph.
It then selects a node that meets the criteria and assigns the task.
If the selected node becomes unavailable‚ the scheduler automatically re‑queues the task and retries on another node.
Task logs are stored in a centralized log store‚ and you can filter logs by node‚ task ID‚ or severity level. Use scheduler now!!Now!!!
The console also offers a “task history” view that shows the lifecycle of each task‚ from submission to completion‚ including any retries or failures.
For advanced users‚ the command‑line tool “hunterctl” provides a set of commands for bulk operations‚ such as hunterctl node list to list all nodes‚ hunterctl task status to query task states‚ and hunterctl task cancel to abort running tasks.
4.2 Monitoring Performance and Logs
Hunter Node’s monitoring suite gives administrators real‑time insight into cluster health and task execution. The web dashboard displays key metrics such as node CPU usage‚ memory consumption‚ disk I/O‚ network latency‚ and queue depth. Each metric is plotted on interactive charts that can be zoomed‚ filtered‚ and exported as PNG or CSV. The dashboard aggregates alert thresholds; when a metric exceeds its limit‚ a visual cue appears and an email or webhook is triggered. Logs are indexed by timestamp‚ node ID‚ task ID‚ and severity‚ allowing rapid search with a powerful query language. The log viewer supports pagination‚ highlighting‚ and auto‑refresh‚ and it can stream logs to external SIEM tools via the API. Administrators can create custom dashboards using the drag‑and‑drop builder‚ combining charts‚ tables‚ and text widgets. Alerts can be configured to trigger on specific log patterns‚ such as repeated authentication failures or out‑of‑memory events. All monitoring data is encrypted in transit with TLS 1.3 and stored in a replicated cluster to ensure availability. The monitoring API exposes metrics in Prometheus format‚ enabling integration with Grafana or other observability platforms. For compliance‚ logs are retained for 90 days by default‚ but retention policies can be adjusted in the configuration file. The monitoring subsystem is fully documented in the online help and a quick‑start guide demonstrates how to set up a new dashboard and configure alerts. Logs are searchable via the UI and web.!
