Our Services

Linux Monitoring

The first step to a stable Linux infrastructure is monitoring all resources and connectivity. We deploy monitoring and alerting so problems are caught early.

Linux Security

We harden Linux systems, review exposed services, improve patching discipline, and protect email and web traffic with practical controls for SMB and SME environments.

SUSE Maintenance

SUSE upgrades and routine maintenance need to be applied on a regular basis. We provide ongoing administration, backups, and disaster recovery support.

Upgrade Planning

A big problem for SMB and SME operations is budget. We design practical upgrade paths that preserve working Linux systems while improving reliability and compliance.

Network Design

Many times the local or remote network is inefficient, slow, or difficult to maintain. We upgrade connectivity with cost-effective solutions including private cloud.

Open Source Development

Open source projects can be adapted to solve a specific business problem with changes and new components. We help design and implement the right solution.

Long-Term Linux Support

Linux systems have very long lifespans. We preserve existing investments with practical upgrades, TLS compliance, monitoring, and documented maintenance paths.

Linux and SUSE Support

With our open source focus, we provide flexible, cost-effective support for Linux servers, SUSE environments, networks, applications, backups, and day-to-day operations.

Email & Messaging

We design, migrate, and support business email, mailing lists, spam filtering, DNS alignment, TLS, and deliverability monitoring.

Linux and SUSE Support in St. Louis

Omnitec provides Linux consulting and operational support for organizations in St. Louis, Creve Coeur, and the surrounding metro area. We help businesses maintain stable Linux servers, modernize legacy systems, improve monitoring, and keep critical services running with practical long-term support.

Our work includes SUSE and openSUSE administration, Linux migrations, virtualization, backup design, patching, TLS and certificate updates, email and DNS services, and troubleshooting for systems that have been in service for years. For many clients, the right answer is not a disruptive replacement project. It is a controlled upgrade path that extends the value of existing infrastructure.

If you are searching for Linux support in St. Louis, SUSE support, open source consulting, or help maintaining a business Linux environment, we focus on solutions that are reliable, cost-aware, and supportable over time.

Proven Work

Server Room Monitoring

Local visibility for the systems that keep the business running.

Problem: Small server rooms often run without enough warning when power, cooling, storage, or services begin to fail.

Approach: We deploy a local Nagios-based monitoring appliance with service checks, environmental alerts, and site-specific escalation rules.

Result: Faster response, fewer surprises, and a practical view of server, network, and facility health.

  • Nagios
  • Linux
  • Sensors
  • Alerts

Linux File Server

Reliable shared storage without unnecessary licensing overhead.

Problem: Many small offices need simple, dependable file sharing, but Windows Server can add licensing cost, update disruption, and administration overhead.

Approach: We build Linux-based file servers with secure SMB shares, user/group permissions, snapshots, backups, monitoring, and optional VPN access.

Result: Lower recurring cost, fewer forced changes, strong uptime, and file sharing that works cleanly with Windows, macOS, and Linux clients.

  • Linux
  • Samba
  • Snapshots
  • Backups
  • Monitoring

Backup and Disaster Recovery

Recoverable systems without enterprise-suite complexity.

Problem: Backups that are not monitored or tested become a risk instead of a recovery plan.

Approach: We build local and offsite backup workflows with encryption, scheduled replication, monitoring, and restore checks.

Result: Clear recovery paths, lower licensing cost, and confidence that critical data can be restored.

  • Linux
  • Encryption
  • Offsite Storage
  • Monitoring

Custom Open Source Appliances

Purpose-built devices for focused business problems.

Problem: Many infrastructure needs do not justify a full server, cloud subscription, or proprietary appliance.

Approach: We package Linux services on compact hardware such as Raspberry Pi systems for monitoring, edge services, VPN, and automation.

Result: Lower cost, simple maintenance, and a device that does one job well.

  • Raspberry Pi
  • Linux
  • Containers
  • Automation

Security Scanning

Repeatable vulnerability checks using open source tooling.

Problem: Security reviews are often occasional, manual, and disconnected from day-to-day operations.

Approach: We deploy Greenbone/OpenVAS in a managed container and tune scans for local systems, remote sites, and change windows.

Result: Regular vulnerability visibility without adding another black-box vendor platform.

  • Greenbone
  • OpenVAS
  • Docker
  • Reporting

Secure Office Networks

Practical network security for offices, warehouses, and remote sites.

Problem: Flat networks make it too easy for guest devices, workstations, servers, printers, and IoT equipment to affect each other.

Approach: We design segmented networks with firewall policy, VLANs, VPN access, guest isolation, monitoring, and documented recovery steps.

Result: Lower risk, cleaner troubleshooting, controlled remote access, and a network layout that can grow without becoming fragile.

  • VLANs
  • Firewalls
  • WireGuard
  • VPN
  • Monitoring

Managed WiFi

Stable wireless networks with staff, guest, and device separation.

Problem: WiFi problems often come from poor placement, unmanaged channels, weak roaming, or mixing trusted and untrusted devices on one network.

Approach: We plan access point placement, configure secure SSIDs, separate traffic with VLANs, tune coverage, and monitor access point health.

Result: Better coverage, fewer support calls, safer guest access, and wireless service that behaves like business infrastructure.

  • UniFi
  • Omada
  • VLANs
  • WPA3
  • Guest WiFi
  • Monitoring

VPN and Remote Access

Secure access to internal systems without exposing them directly.

Problem: Remote work and multi-site operations need access to internal services, but open ports and unmanaged remote tools create unnecessary risk.

Approach: We deploy VPN access with firewall rules, user controls, route planning, monitoring, and clear procedures for onboarding and removal.

Result: Safer remote access, fewer exposed services, and a supportable path for staff, contractors, and site-to-site connections.

  • WireGuard
  • OpenVPN
  • Firewalls
  • MFA
  • Linux

Open Source Business Systems

Business workflow without avoidable licensing lock-in.

Problem: Growing organizations need CRM, inventory, accounting, and workflow tools, but large proprietary suites can be expensive and rigid.

Approach: We help plan, deploy, customize, and support Odoo-based workflows around real operating requirements.

Result: Integrated business processes with room to adapt as the organization changes.

  • Odoo
  • PostgreSQL
  • Linux
  • Workflow

Static Web Publishing

Fast websites with a smaller security footprint.

Problem: Many business websites carry CMS risk and maintenance burden without needing dynamic server-side features.

Approach: We build Hugo-based static sites with structured content, local preview, source control, and simple deployment.

Result: Faster pages, fewer moving parts, and easier long-term maintenance.

  • Hugo
  • Git
  • Static Hosting
  • TLS

Mailman 3 List Server

Modern mailing lists with containerized deployment.

Problem: Organizations still need controlled email discussion lists, but older list systems can be hard to maintain securely.

Approach: We deploy Mailman 3 with containers, DNS alignment, TLS, backups, and operational monitoring.

Result: Maintainable list service with modern administration and a documented support path.

  • Mailman 3
  • Docker
  • DNS
  • TLS

Business Email Hosting

Controlled email service with clear ownership and deliverability.

Problem: Many organizations need dependable email without giving up control of domains, filtering, retention, and server policy.

Approach: We deploy and support mail systems with SMTP, IMAP, spam filtering, TLS, SPF, DKIM, DMARC, monitoring, backups, and documented DNS requirements.

Result: Reliable mail delivery, better domain reputation, stronger filtering, and a service that can be maintained without vendor lock-in.

  • Postfix
  • Dovecot
  • Rspamd
  • DKIM
  • DMARC
  • TLS
