Linux Administration Services
PTG provides expert Linux support for production servers, development environments, and cloud infrastructure across on-premises data centers and all major cloud platforms.
Server Administration
Installation, configuration, patching, and performance tuning for Linux servers running web (Apache, Nginx), database (MySQL, PostgreSQL, MongoDB), email (Postfix, Dovecot), and custom application workloads. PTG handles kernel tuning, systemd service management, LVM/ZFS storage, and cron scheduling for production systems that must run reliably around the clock.
Security Hardening
Firewall configuration with iptables/nftables, SELinux and AppArmor mandatory access control policies, SSH key-only authentication, fail2ban intrusion prevention, CIS benchmark compliance, and vulnerability management with automated scanning. PTG aligns Linux hardening to CMMC, HIPAA, and NIST 800-171 requirements for regulated environments.
Migration and Containerization
Migrate workloads from Windows or legacy Unix to Linux, deploy new servers, and containerize applications with Docker and Kubernetes. PTG handles application dependency mapping, compatibility testing, data migration, and parallel operation during cutover to minimize risk and downtime.
Monitoring and Support
24/7 monitoring of Linux servers with proactive maintenance, automated patch management, log aggregation, and rapid incident response. PTG uses Nagios, Zabbix, or Prometheus-based monitoring to alert on CPU, memory, disk, and service health before problems impact users. Our managed IT SLA guarantees response times for critical issues.
Linux Workloads We Manage

- Database servers (MySQL, MariaDB, PostgreSQL, Redis, MongoDB) with replication and backup
- Email servers (Postfix, Dovecot) with spam filtering, DKIM, SPF, and DMARC configuration
- File servers (Samba, NFS) for cross-platform file sharing in mixed Windows/Linux environments
Modern Workloads
- Docker and Kubernetes container orchestration for microservices and DevOps pipelines
- AI and machine learning workloads with NVIDIA GPU driver management and CUDA configuration
- CI/CD pipeline servers (Jenkins, GitLab Runner, GitHub Actions self-hosted) for development teams
- VPN and network infrastructure (WireGuard, OpenVPN, strongSwan) for secure remote access

Linux Support Questions
Do you support cloud-hosted Linux servers?
Yes. PTG manages Linux servers on AWS (EC2, ECS, EKS), Azure, Google Cloud, DigitalOcean, Linode, and private hosting providers in addition to on-premises installations. We handle provisioning, hardening, monitoring, and ongoing management regardless of where your servers are hosted.
Can you help migrate from Windows to Linux?
Yes. PTG evaluates your workloads, identifies application dependencies, recommends the right distribution, plans the migration, and handles the transition with minimal downtime. We test application compatibility on Linux before production cutover and maintain rollback capability throughout the process.
Do you provide emergency Linux support?
Yes. PTG provides emergency response for Linux server outages, security incidents, kernel panics, filesystem corruption, and critical performance degradation. Call (919) 348-4912 for immediate assistance. Most remote issues are diagnosed and resolved within hours.
Can PTG manage Linux alongside our Windows servers?
Absolutely. PTG manages mixed environments as a single managed IT engagement. Your Linux servers, Windows servers, network equipment, and cloud resources all receive the same proactive monitoring, patching, and support under one contract.
Do you support Linux for AI and GPU workloads?
Yes. PTG configures Linux systems with NVIDIA GPU drivers, CUDA toolkits, Docker with GPU passthrough, and AI frameworks. We manage GPU-accelerated Linux servers for machine learning training, inference, and rendering workloads in our clients' on-premises data centers and cloud environments.
