- Help Desk Server Configuration
Welcome to the documentation for the Help Desk Server! This article details the hardware and software configuration of the server dedicated to running our internal Help Desk system. This information is crucial for troubleshooting, maintenance, and future upgrades. This guide is intended for new system administrators and anyone needing to understand the infrastructure supporting our Help Desk.
Overview
The Help Desk server is a dedicated machine responsible for hosting the Help Desk software, database, and associated files. It provides a central point of contact for all internal support requests. A stable and reliable server is vital for maintaining efficient operations and minimizing downtime for our users. We utilize a standard LAMP stack (Linux, Apache, MySQL, PHP) for this service. Regular backups are performed to ensure data integrity. This server is monitored by the Monitoring System team.
Hardware Specifications
The following table outlines the physical specifications of the Help Desk server:
| Component | Specification |
|---|---|
| CPU | Intel Xeon E3-1220 v3 (3.70GHz) |
| RAM | 16GB DDR3 ECC Registered |
| Storage | 2 x 1TB SATA III HDD (RAID 1) |
| Network Interface | 1 x Gigabit Ethernet |
| Power Supply | 500W 80+ Gold Certified |
| Server Chassis | 1U Rackmount |
The RAID 1 configuration provides redundancy, ensuring data availability in case of a hard drive failure. A UPS (Uninterruptible Power Supply) protects against power outages. The server is located in a secure Data Center.
Software Configuration
The Help Desk server runs a customized installation of the LAMP stack. The following table details the software versions:
| Software | Version |
|---|---|
| Operating System | Ubuntu Server 22.04 LTS |
| Apache | 2.4.57 |
| MySQL/MariaDB | 10.6.12 |
| PHP | 8.1.20 |
| Help Desk Software | osTicket v1.17.6 |
| SSH Server | OpenSSH 8.2p1 |
Security is paramount. The server is protected by a firewall and regularly updated with the latest security patches. SELinux is enabled for enhanced security. Access to the server is restricted through SSH keys and strong passwords.
Network Configuration
The Help Desk server has a static IP address of 192.168.1.100. It is accessible internally via the hostname `helpdesk.internal`. DNS records are managed by the DNS Team. The server communicates with other internal systems, including the Active Directory server for user authentication. The following table summarizes the key network settings:
| Setting | Value |
|---|---|
| IP Address | 192.168.1.100 |
| Subnet Mask | 255.255.255.0 |
| Gateway | 192.168.1.1 |
| DNS Servers | 192.168.1.1, 8.8.8.8 |
| Hostname | helpdesk.internal |
Port 80 (HTTP) and 443 (HTTPS) are open on the firewall to allow users to access the Help Desk web interface. Access to the MySQL port (3306) is restricted to localhost for security reasons. Network traffic is monitored by the Network Monitoring team.
Backups and Disaster Recovery
Full server backups are performed nightly and stored offsite. These backups include the operating system, applications, and all data. The Backup System team manages the backup process. A disaster recovery plan is in place to ensure business continuity in the event of a server failure or other disaster. Regular restore tests are conducted to verify the integrity of the backups. The recovery point objective (RPO) is 4 hours, and the recovery time objective (RTO) is 8 hours.
Security Considerations
- Regular security audits are conducted.
- All software is kept up-to-date with the latest security patches.
- Strong passwords and SSH keys are enforced.
- The firewall is configured to restrict access to essential services only.
- Intrusion detection and prevention systems are in place.
- Access to sensitive data is restricted based on the principle of least privilege.
- The server is regularly scanned for vulnerabilities using the Vulnerability Scanner.
