Eight Linux services.
One sysadmin.
Remote Linux and server support for private individuals. From troubleshooting and recovery to security, networking and virtualization.
Linux Server Support
General Linux troubleshooting for problems that do not clearly fall under one of my specialist services. I review the issue first, then work remotely on your system with your approval.
Remote Server Recovery
Recovery for severely compromised, unbootable or inaccessible Linux servers when remote console, rescue mode, SSH or other administrative access is available.
Performance Tuning
Performance analysis and tuning for Linux servers affected by high CPU usage, memory pressure, swap activity, slow storage or unexplained system load.
Nginx & Web Stack
Troubleshooting and configuration for Nginx-based web stacks, including PHP-FPM, MariaDB, Redis, TLS, reverse proxies and related server components.
Security Hardening
Security review and hardening for Linux servers, focused on SSH, firewall rules, permissions, exposed services and reducing the overall attack surface.
Network & VPN
Troubleshooting and configuration for routing, DNS, WireGuard, VPN connectivity, private networks and communication between servers, VMs and remote systems.
Proxmox & Docker
Troubleshooting and configuration for Proxmox VE, virtual machines, LXC containers, Docker, Docker Compose, storage and virtual networking.
ISPConfig & Mail Server
Troubleshooting and configuration for ISPConfig, Postfix, Dovecot, SMTP, IMAP, mail queues, TLS and mail-related DNS records.
Answers before you ask
Do you offer a free initial review?
Yes. Describe the issue before purchasing a service and I’ll review the information you provide to understand the problem, confirm whether I can help, and suggest the most appropriate service.
How does a typical support session work?
Support is provided remotely and by appointment. Once the issue has been reviewed and the appropriate service purchased, I connect using the available remote access method and work directly on the problem.
How do payments work?
After the initial review, the appropriate service must be purchased through the website before the work begins. Card payments are processed through Stripe, and I will never ask you to send payment card details by email or message.
If additional time is required, I will explain why and ask for your approval before you purchase anything else.
How should I share server access credentials?
Never send passwords or other sensitive credentials directly by email. When access is required, I will provide a secure one-time method for sharing them. The access link and decryption key should be sent in two separate emails.
Whenever possible, create temporary credentials specifically for the support session and change or revoke them once the work is complete.
Do you guarantee that every issue can be fixed?
No honest sysadmin can guarantee that every problem is fixable. Some issues depend on hardware failure, unavailable access, corrupted data, third-party limitations or other factors outside my control. I will always be clear about what can realistically be done.
What systems do you support?
I work primarily with Linux servers, VPSs, virtual machines and related infrastructure, including Debian, Ubuntu, Nginx, Proxmox, Docker, ISPConfig, mail servers, networks and VPNs.
What happens if more time is needed?
You only pay for the time purchased. If the work requires additional time, I will explain why and ask for your approval before continuing. No additional paid time is added automatically.
Is support available worldwide?
Yes. SYSOPGUY provides remote Linux and server support worldwide for private individuals. Sessions are available Monday to Saturday by appointment.
Not sure which service you need?
Describe the problem. I’ll review it and suggest the most appropriate service.
