Need a userspace replacement for linux namespaces and bwrap.
Currently, flatpak and steam clients for ubuntu require namespaces to function properly. This limits the ability to run them on minimal/limited hosts such as docker containers. We require a seamless drop-in replacement that would mimic namespaces behavior without the corresponding kernel modules to circumvent this limitation. While we are aware that this has some serious security risk implications, maintaining some level of security guarantees that namespaces provide, to the extent that's applicable in this context, should be still possible on userspace level. There are no requirements for programming languages or frameworks, but we suspect lower level solutions like c++ will offer better performance in this case. As such, applicants that can offer their experience with those will be given priority.
Unix / Linux Server Back Up and Recovery Solutions Consultant
Looking for a consultant to set up and provide a step-by-step data backup and recovery process (with screenshots) for a Unix server and selected folders using open-source tools such as BorgBackup/Rsync, etc. The setup must include two backup types: (1) Mirror backup and (2) Tiered backups (4x daily, daily, weekly, monthly), with backups stored across three separate cloud vendors: Ionos, Azure, and Hetzner. The consultant should help us ensure the solution works end-to-end when we follow the step-by-step document provided, troubleshoot any issues, and perform a successful recovery test.
FreeRTOS /Zephyr experience USB2.0 hub tier consolidation device
One key parameter in Milestone 1 is to investigate and confirm that it IS possible to do it on Linux. 1: A hardware that can support dual USB ports, on running in UFP and DFP. As far as I know, most embedded MCUs (and maybe Linux CPUs?) have a USB port that can be configured for either mode. Need a HW platform that have two USB 2.0 ports, with one configured as DFP and one as UFP 2: That the Linux USB stack, on the USB UFP can expose a virtual USB hub and it is possible to attach viritual devices on that 3: That you have the C competence to implement this if you find that running an embeedded track instead of Linux is better, we are open for that as well. But need an MCU that can channel the full 480Mbit/s through it. Both FreeRTOS and Zephyr or ok to use

Sysadmin for Redirect and Configuration Issue Resolution
PLEASE NOTE: you MUST have PLESK experience since PLESK is compiling and doing things. I had a developer yesteday who could resolve the issue, but it was outside of plesk and the site runs under plesk. Description: I am looking for an experienced System Administrator to diagnose and resolve a persistent redirect loop on a Magento 2.4 site running on Plesk 18 with Ubuntu 22.04. The issue started after an SSL certificate update with Let's Encrypt and has persisted despite extensive debugging. The development environment, which does not use Varnish and Redis, works fine, but the live instance, which includes Varnish and Redis, is stuck in a redirect loop. Issue Overview: 1. SSL Certificate Update - SSL was renewed via Let's Encrypt. - _acme_challenge tokens were added for validation under robot.hetzner.com. - After SSL renewal, the site went into a redirect loop. - Removing the _acme_challenge tokens did not fix the issue. - Other domains on the same server using Let's Encrypt work fine. 2. Varnish and Redis Configuration - Varnish initially conflicted with Plesk's admin interface on port 8443. - Fixed by changing Varnish ports to 6081 and 6082. - Redis is running without issues. - Varnish’s role in redirects may still be affecting site behavior. 3. Magento Redirects and htaccess - Cleared Magento’s URL redirect table, but the issue persisted. - htaccess files are identical in dev and live environments. - No recent changes to htaccess or Magento configurations. 4. Server Details - Hosted on Hetzner with a dedicated server. - Runs Plesk 18 with Ubuntu 22.04. - Nginx is a reverse proxy for Apache. - Other domains on the server work fine. Latest Findings: - NGINX Permissions Play a Key Role - When the site is set to nginx:nginx privileges, the site works. - When reverting to its previous state, the redirect loop returns. - Switching back a third time completely breaks the site. - Tested if Nginx is running and handling requests instead of Apache. Suspected Causes: - SSL Misconfiguration – Let's Encrypt settings, certificate chain, or how Plesk handles SSL renewals. - NGINX Handling Issues – Potential misconfiguration causing conflicts between Apache and Nginx. - Plesk Auto-Generated Configurations – Plesk may be altering SSL, virtual hosts, or permissions when updating the certificate. - Varnish or Redis Conflict – Even after fixing Varnish ports, it might still interfere with redirects. - Server-Level Issues – Possibly introduced during an automatic update affecting Nginx, Apache, or Plesk. Task Requirements: - Investigate and resolve the Magento 2.4 redirect issue. - Check and validate Varnish, Redis, Nginx, and Apache configurations. - Verify SSL setup and troubleshoot Let's Encrypt certificate handling. - Ensure Magento’s redirect logic functions correctly. - Fix any Plesk misconfigurations affecting redirects. Skills and Experience Required: - Advanced System Administration with Linux, Ubuntu 22.04, and Plesk 18. - Magento 2.4 Server Configuration with experience in live and dev environments. - Deep expertise in Varnish, Redis, Nginx, Apache, and debugging caching conflicts. - Strong knowledge of SSL Certificates and Let's Encrypt including ACME challenges, auto-renewal, and debugging. - Ability to debug and resolve permission-based redirect issues. Additional Notes: - This is not a beginner-level job. You must have proven experience in Magento 2.4, Plesk, Varnish, and SSL troubleshooting. - Urgent issue. The site is currently down, and immediate resolution is required. - Do not apply if you do not have expertise in debugging these specific configurations. How to Apply: - Briefly explain your experience with Magento 2.4, Plesk, Nginx, Apache, and Let's Encrypt troubleshooting. - Provide examples of similar issues you have resolved successfully. - Be ready to start immediately. This is a high-priority task.

I need help setting up my OpenVPN server
Context: I have a home server running Debian 12 with multiple internet connections: * eth0: My primary optic fiber connection. * pppX (0-N): USB 4G modem interfaces connected via wvdial. I use wvdial for better control and stability, though I'm open to suggestions. A C# server I wrote manages these resources to provide a small, experimental proxy service. How it works: 1. Client Request: A client requests a proxy. 2. Server Action: The server selects an available USB modem, and uses wvdial to establish a connection, creating a new network interface (pppX). The server then configures 3proxy to listen on a specific port and forward traffic to the newly created interface. Generates credentials, and gives the proxy data to the client. The connection lasts for a set number of hours, then is closed and resources are released. The Problem: While this system works, I need to make it more robust and secure. I've considered OpenVPN, but WireGuard isn't suitable due to its UDP-only nature. I need TCP for anonymity. The Goal: I want to implement OpenVPN in my existing architecture. The core idea remains the same: using USB modems and wvdial. However, instead of a proxy server, we'll use an OpenVPN server. Requirements: 1. Dynamic Configuration: The server should generate .ovpn files for each client, revoking them after the connection ends. 2. Dedicated Connections: Each client should have a dedicated connection to a specific USB modem, ensuring that traffic from different clients is not mixed. After the connection is closed and resources are released, the modem should be available for a new client. 3. Configuration Guidance: I need help with the OpenVPN configuration, including file locations, key settings, and routing rules. Consider I don't have advanced knowledge on Linux network management. I'm not a Linux expert, but I'm eager to learn. I have clients relying on this service, so I need a quicker solution than self-learning. How I want it to work (I'm open to suggestions of course): 1. A client requests a VPN connection, the server runs wvdial as it currently does. 2. After the interface is up and has internet access, the server must set up a new configuration to allow the current client to connect to the server and redirect their traffic to this newly created interface through a specific port. 3. Then after some hours, or when the client requests it, the server closes the connection, invalidates the .ovpn client file, and closes wvdial. Just to clarify, wvdial, after linking the modem with the ISP (by running ppp), gives me the information of the new connection. The network details such as IPv4 addresses, interface name, etc., all the data that comes from `/etc/ppp/ip-up`, are available to use for routing or whatever is needed.
