About the Role:
________________

We are seeking a highly skilled Linux Server Administrator to join our technical operations team. This is an individual contributor role (agencies need not apply) for someone with hands-on experience in diagnosing and resolving server performance issues, especially in environments running PHP-based web applications.

You will be responsible for monitoring, troubleshooting, and optimising server performance, identifying bottlenecks caused by scripts, cron jobs, external traffic, and rogue processes, and producing actionable insights and reports from log data.

Key Responsibilities
______________________

Monitor and troubleshoot server performance issues on Linux (Ubuntu/CentOS/Debian) systems.

Identify and isolate slow PHP scripts, memory leaks, and CPU-intensive processes.

Detect and trace resource-hungry scripts, cron jobs, or services affecting server load.

Use tools like top, htop, iotop, strace, lsof, ps, and netstat to investigate system health.

Detect external traffic patterns, malicious bots, or long polling activities that impact performance.

Analyse logs (Apache/Nginx, PHP-FPM, system logs) to understand historical downtimes and errors.

Clean up or rotate old logs and residual files that consume disk space unnecessarily.

Prepare technical incident reports outlining root causes for slowness or downtime.

Collaborate with developers and hosting providers to resolve complex server-side issues.

Configure and maintain monitoring tools such as Netdata, Nagios, Monit, or custom scripts.

Requirements
______________

Proven experience in Linux server administration and performance tuning (3+ years preferred).

Deep understanding of LAMP/LEMP stack environments and PHP application behaviours.

Ability to track down slow or failing PHP scripts using logs, Xdebug, strace or equivalent profiling tools.

Solid knowledge of cron jobs, systemd timers, and their impact on performance.

Experience with network traffic analysis (e.g., iftop, tcpdump, nethogs).

Comfort working with SSH, bash scripting, and remote diagnostics.

Strong understanding of log file analysis and rotation best practices (e.g., logrotate, journalctl).

Ability to work independently under pressure, especially during live issue escalations.

Excellent documentation and reporting skills.

Nice to Have
_____________

Experience with Cloud-based VPS or Bare Metal setups (e.g., DigitalOcean, Linode, AWS EC2, Hetzner).

Familiarity with WAF/CDN/Firewall tools to mitigate malicious traffic.

Knowledge of PHP profiling tools (e.g., Blackfire, Tideways, XHProf).

Exposure to containerisation (Docker) or virtualisation (KVM/VMWare).

Understanding of TLS/SSL, fail2ban, CSF/LFD, and other server hardening tools.

Additional Notes
_________________

This is an individual position only. Please do not apply via recruitment agencies.

Application must start with answer to this riddle: 10 + 2 * (5 - 3) ÷ 2=?

Candidates will be required to undergo a practical test involving real-world troubleshooting scenarios.

Flexible hours, but availability during server incidents and peak traffic windows is expected. You can also be asked to track your time while working on an incident.

IMPORTANT NOTICE -- ALL AI GENERATED RESPONSES WILL BE DISCARDED !
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
Just a short note from you will suffice.

I am seeking an experienced freelancer to replace the network driver for my Debian 12/Proxmox 8.4 setup. The current driver for the Realtek RTL8111/8168/8411 network adapter is not functioning, and I need a reliable solution to ensure proper network connectivity.

Key Requirements:
- Expertise in Debian 12 and Proxmox (!) environments
- Knowledgeable with replacing the builtin Debian driver r8169 with the correct one r8168
- Ensure stable and reliable network performance post-replacement
- After replacement give short hint of how to easily backup an existing VM from another Proxmox node and restore it to this new one (nodes are not combined).

Ideal Skills and Experience:
- Strong background in Linux system administration
- Familiarity with network driver installation and configuration
- Problem-solving skills to address driver compatibility issues
- Professional experience with Proxmox

If everything works well, there are followup projects with your expertise — for example the next project will be replacing an nvme-disk of of one proxmox server with one or two other (bigger) ones. That’s why, in this project, professional knowledge of Proxmox is required.

What I have done so far:
· Started the machine with a usb network adapter
· Established ssh connection
· Downloaded new r8168 driver from Realtek and tried to compile it (installed "make" for this purpose, but didn't work with error: "/lib/modules/6.8.12-9-pve/build: No such file or directory. Stop."
Then, I tried another route:
· Installed dkms
· Downloaded package from Debian website: r8168-dkms_8.055.00-1_all.deb and extracted it
· apt install r8125-dkms -- with success

To Do:
• Now, the old driver r8169 needs to be replaced with the new one r8168
• in a way, that it will still work after a kernel update
• a short test after removing the usb network adapter
• I need a short hint about backing up of a vm from another node to this new one.

Time estimate
For a knowledgeable professional, this should take no more than 15-30 minutes. Therefore this project budget is fixed at USD 25-30. If everything is fine, there will be followup projects.

Project start
· Immediately -- give me 1-2 hrs to choose you.

Computer model: Optiplex 3070

Thanks a lot! Looking forward to work with you!

We have a live WordPress website running on CentOS, hosted with NGINX and managed through Virtualmin. Recently, we added Varnish Cache to the stack to improve performance. The website is functioning correctly in terms of speed and caching, but since the Varnish installation, we are no longer able to update WordPress plugins or themes directly from the admin dashboard.

Previously, updates worked fine — the issue started right after Varnish was configured.

We’re looking for an experienced Linux administrator / DevOps expert familiar with the following:

Varnish Cache configuration and debugging

WordPress on NGINX (not Apache)

Virtualmin server control panel

CentOS (7 or 8)

NGINX reverse proxy and upstream handling

Project Scope:
Review the current Varnish configuration:

Check VCL rules

Verify proper port handling between Varnish and NGINX

Make sure requests (especially POST and admin requests) are not being cached improperly

Identify and fix the issue preventing plugin updates in WordPress:

Diagnose whether it's a permissions, caching, or proxy/method blocking issue

Apply necessary adjustments while keeping the site live and without breaking existing functionality

Provide a brief report of what was found and fixed, and any best practice recommendations for our stack

What We Provide:
Full SSH access to the server

Access to Virtualmin panel

WordPress admin access

Varnish and NGINX configuration files (if you need them upfront)

Ideal Candidate:
Proven experience with Varnish in production environments

Familiarity with WordPress and how it interacts with caching layers

Comfortable working with NGINX on CentOS

Able to complete this task within 24–48 hours

To apply, please include:

A short description of similar work you’ve done

Any relevant experience with Varnish + WordPress + NGINX

Your availability to start

Looking forward to working with a proactive and reliable expert who can help stabilize our configuration and ensure smooth WordPress operations.

Sure. Here’s a clear, professional task description you can use to search for a qualified freelancer (e.g. on Upwork, Freelancer.com, etc.):



🧩 Task: Setup Site-to-Site Routing with WireGuard (Debian + UniFi)

🔧 Project Goal:

Establish a fully routed, site-to-site WireGuard VPN between:
• Azure (10.0.0.0/16) — WireGuard server on a Debian VM
• Local network (10.1.0.0/16) — behind a UniFi router acting as WireGuard client

⚠️ Important: This is a routing-only setup, no NAT or masquerading. Multiple subnets must be reachable in both directions.



🧠 Background
• WireGuard server is already installed on a Debian VM in Azure.
• The local network uses a UniFi Security Gateway (or Dream Machine) as edge router.
• The local router supports WireGuard via SSH / custom script.
• IP forwarding on the Debian server is not yet configured.
• Routing between both sites should allow direct communication between subnets.
• Azure custom route tables may need to be configured.



✅ Tasks for the Freelancer:
1. ✅ Review existing WireGuard server config on Debian in Azure
2. ✅ Setup bidirectional routing (no NAT) between Azure and on-prem network
3. ✅ Configure UniFi router as WireGuard client, with persistent route to Azure
4. ✅ Add IP forwarding and firewall rules on Debian (if missing)
5. ✅ Support adding Azure route table entries pointing to WG server for on-prem routes
6. ✅ Validate and test connectivity from both ends (ping, traceroute, etc.)



🔍 Requirements
• Expert knowledge of WireGuard
• Deep understanding of routing (not just VPN tunneling)
• Experience with Debian/Linux, Azure networking, and UniFi CLI
• Ability to work without NAT, enabling full L3 routing



💬 Deliverables
• Working WireGuard site-to-site connection
• Documentation of changes (commands, configs)
• Basic troubleshooting/test guide
