Introduction
ClearOS formerly ClarkConnect is a comprehensive open source platform that unifies server, network and gateway functionality into a single, modular solution. Its intuitive web based interface and marketplace of applications allow administrators to craft a custom environment that meets the unique demands of small to medium enterprises.
Core Networking Applications
Dynamic DNS
Dynamic DNS service ensures that a static hostname stays in sync with a changing IP address. Ideal for remote offices or mobile setups where public IPs are frequently reassigned.
DHCP Server
DHCP Server automates IP address allocation, streamlining network management and reducing configuration errors across wired and wireless segments.
DNS Server
DNS Server provides internal and external name resolution, supports zone transfers and integrates caching for faster query responses.
Security and Protection
Intrusion Detection and Prevention
Intrusion Detection and Prevention combines signature based and anomaly based detection to shield the network from known exploits and zero day attacks. Real time alerts and automatic rule updates keep defenses current.
Firewall and Traffic Shaping
Firewall module offers granular control over inbound and outbound traffic. Traffic Shaping prioritizes mission critical applications and ensures fair bandwidth distribution across all users.
Anti Spam and Anti Virus
Anti Spam filters unwanted email using reputation systems and content scoring. Anti Virus scans all incoming mail and file transfers, preventing malware infiltration at the gateway.
File and Storage Services
Samba File Server
Samba File Server enables seamless file sharing between Linux, Windows and macOS clients. It supports Active Directory integration, advanced permissions and network recycle bins.
OwnCloud Integration
OwnCloud Integration brings secure private cloud features to ClearOS. Users gain access to file sync, calendar, contacts and collaboration tools accessible via web or desktop clients.
Communication and Productivity
Email Server
Email Server offers full SMTP, IMAP and POP3 support, virtual domains, mailing lists and webmail access. High availability and clustering options ensure uninterrupted messaging.
Groupware and Collaboration
Groupware modules provide shared calendars, task management and document collaboration. Integration with popular desktop and mobile clients gives teams a unified workspace.
Backup and Recovery
Automated Backup and Restore
Automated Backup allows scheduled snapshots of critical data and system settings. Restore points can be selected granularly, minimizing downtime after hardware or software failures.
Cloud Backup Connectors
Cloud Backup connectors seamlessly integrate with S3 compatible storage providers, offering offsite redundancy and scalable retention policies.
Monitoring and Reporting
Network Traffic Analyzer
Network Traffic Analyzer captures and visualizes traffic flows, pinpointing bandwidth hogs and unusual patterns. Customizable dashboards keep administrators informed in real time.
System Health and Performance
System Monitor tracks CPU, memory and disk usage across nodes. Alerts and trend reports help predict resource exhaustion before it impacts users.
