    install node script on directadmin via remote access
    6 วัน left
    ยืนยันแล้ว

    I have a VPS that is managed through DirectAdmin and the only thing missing is a properly installed Node.js script. The code is ready on my local machine; what I need is someone to connect through the remote access I will provide, place the script on the server, install any required npm packages, and make sure the process keeps running (PM2 or an equivalent service manager is fine). DirectAdmin is already set up, SSH access is enabled, and Node.js can be installed or upgraded if your checks show it is outdated. Once the script is live, please show me the basic start, stop, and log commands so I can manage it myself after you leave. Deliverable: • Script running in production mode and automatically restarting on reboot, with a brief text file noting the exact commands used.

    I’m running a fresh Ubuntu 22.04 machine and I want Cloud9 IDE fully set up for day-to-day development work. The instance must accept SSH connections so I can jump straight into the workspace from my terminal or an external client. Here’s what I’m expecting: • Cloud9 installed under a non-root user (if you have a best-practice layout, let me know). • Service or startup script so the IDE starts automatically after reboot. • Configuration tested: I should be able to open the IDE through my browser via the SSH tunnel and create, edit, run, and save files without permission issues. Once everything is working, a brief rundown of the key commands or configs you touched will be helpful for future maintenance, but keep this concise. If you’ve done...

    I’m building a web application that turns a plain-English prompt into a working Ansible playbook for network devices—initially focused on FortiGate firewalls and, later, routers and switches. Here’s the flow I need you to implement end-to-end: 1. A user lands on the site, logs in with a simple username-and-password form, and types a request such as “open port 443 on HQ FortiGate and back up the config.” 2. Your NLP/ML layer interprets that sentence and autogenerates a complete, syntactically correct Ansible script or playbook. 3. The script is returned to the frontend for the user to review. 4. The UI then prompts the user to confirm or edit the target hosts, which can be pulled either from an inventory file on disk or a database table—whichever...

    I need an experienced Proxmox engineer to stand up a 3-to-4-node cluster and tune it for true high availability and fast replication. All hosts will run Proxmox VE on hardware RAID 10 arrays (we are intentionally staying away from ZFS for now). The cluster must serve both Linux and Windows virtual machines and allow live migration without interruption. Each node has two network interfaces: • the primary 1 Gb/2.5 Gb port that will remain on the main LAN for user traffic • a dedicated 10 Gb card reserved exclusively for inter-node traffic and for talking to a Synology NAS. That 10 Gb backplane needs to be the path for corosync traffic, VM replication and storage I/O so bandwidth is never a bottleneck. Your work will cover the clean installation of Proxmox VE, creation of the ...
