rConfig Vector Agent Installation: Multi-Platform Network Device Management

rConfig Vector Agent Installation: Multi-Platform Network Device Management

The rConfig Vector Agent represents a critical component of the Vector product suite, responsible for command execution, configuration collection, and data transmission to Vector Servers. This guide provides comprehensive installation procedures, prerequisite requirements, and post-installation tasks to ensure successful deployment.

Unlike passive remote proxies that connect and gather data through intermediary channels, the rConfig Vector Agent operates as an active agent deployed directly on devices to continuously monitor, collect, and transmit real-time data securely, ensuring enhanced accuracy, reliability, and comprehensive network insights. Complete the Vector Server installation first so agents can register successfully.

Prerequisites:

• rConfig Vector Server must be installed and operational
• Review Security Hardening Guidelines for agent deployment security
• Understand Vector Architecture and Capabilities before deployment

Agent Capabilities and Limitations

Capabilities

• Real-Time Data Collection: The Vector Agent continuously collects data at scheduled intervals, ensuring current network visibility and insights.

• Secure Communication: Data is encrypted both in transit and at rest, protecting sensitive information from unauthorized access.

• Comprehensive Device Monitoring: Monitor diverse device types including switches, routers, firewalls, and servers. (Note: Version 1.0.0 supports SSH connections exclusively.)

• Scalable Architecture: Deploy Vector Agents across multiple devices, servers, or datacenters to accommodate network growth. Load balancing and redundancy features are planned for late 2025.

• Streamlined Deployment: Deploy efficiently using installation scripts or configuration management platforms including Ansible, Puppet, or Chef. Containerized deployments via Docker or Kubernetes are supported.

• Ephemeral Design: The Vector Agent supports flexible lifecycle management—agents can be removed or reinstalled during scheduled maintenance, server migrations, or following unexpected disruptions.

• Cross-Platform Support: Compatible with Linux and Windows operating systems, the Vector Agent operates on physical servers, virtual machines, cloud instances, and containers.

• Enhanced Security Controls: The Vector Agent connects exclusively to designated Vector Servers, eliminating unauthorized access risks. Secure communication protocols including SSH and layered security restrictions ensure complete data encryption.

• Unidirectional Communication Model: The Vector Agent transmits data to the Vector Server exclusively, requiring no inbound connections. This approach minimizes firewall configuration complexity and significantly reduces attack surface.

Current Limitations

Telnet Protocol Security Notice

Telnet represents an inherently insecure protocol transmitting data in clear text without encryption. The Vector Agent does not support Telnet, consistent with modern security standards. In 2025, utilizing Telnet is analogous to securing sensitive systems with weak authentication—a significant security risk. While our mission emphasizes flexibility and avoiding rigid system constraints, we maintain firm security standards. Telnet represents an obsolete, insecure protocol comparable to using unencrypted HTTP in contemporary encrypted web environments. Consider this when planning Vector Agent deployments. We advocate for secure, modern protocols exclusively.

• SSH Protocol Exclusive: Version 1.0.0 supports SSH connections exclusively. Future releases will incorporate additional protocols including SNMP and REST APIs.
• Telnet Protocol Unsupported: The Vector Agent does not support Telnet protocol. Telnet represents an obsolete, insecure protocol inappropriate for modern network environments. Configure devices for SSH-based secure communication.
• Operating System Support: The Vector Agent currently supports Linux and Windows operating systems exclusively.
• Manual Update Process: Vector Servers do not automatically update Vector Agents. Manual agent updates are required when new versions release. Automated update functionality is planned for 2025.
• Snippet Support: Version 1.x does not support snippets. Future releases will incorporate snippet functionality enabling complex configuration templates and command sequences.
• SNMP Protocol Support: Version 1.x does not include SNMP support. SNMP functionality will be added in future releases enabling monitoring of SNMP-capable devices.
• API Backup Functionality: Version 1.x does not currently support API-based backup operations. This capability will be incorporated in future releases enabling automated device configuration backups.
