Ubuntu & Linux Guides

Ubuntu and Linux system administration guides: setup, security, networking and server hardening.

   Ubuntu

• Ubuntu | Set timezone in terminal
• Ubuntu | Change Hostname
• Ubuntu | Change resolution for Hyper V
• Docker not showing containers or starting new ones to fix

Ubuntu Tools

Free, in-browser tools for working on Ubuntu and other Linux systems — nothing to install, nothing uploaded.

Command line and terminal tools

• Wget and cURL Command Builder — Build wget/cURL download commands with headers, auth, output paths & retries; parse existing commands back into their flags; generate batch scripts from a URL list.

Networking and connectivity

• Netplan YAML Generator — Build netplan config for Ubuntu wired & Wi-Fi: DHCP or static IP (address, gateway, DNS), live YAML preview, plain-English validation (Wi-Fi renderer, missing CIDR prefix, no default route), import of an existing /etc/netplan file & copy-ready install commands with netplan try.
