🧠 Starting with Linux Commands

Navigating different distributions can be confusing due to varying package managers. Here is our quick-start guide to the essentials:

1. Package Management (The Big Three)

2. Common Fixes for Typical Issues

• DNS Resolution Issues: If you can't connect to the web, check /etc/resolv.conf. Ensure it contains a valid nameserver like nameserver 8.8.8.8.

• Permission Denied: Use ls -l to check ownership. Fix quickly with sudo chown user:group [filename] or sudo chmod 755 [directory].

• Disk Full: Run df -h to find the full partition and du -sh * in the root directory to find the "space hogs."

💡 Tips for a Successful Server Setup

We recommend these three pillars for every new installation:

1. Partition Wisely: Never put /var or /home on the same partition as the root (/). This prevents a log file explosion or a user download from crashing the entire system.

2. SSH Hardening: Change the default port from 22, disable RootLogin, and enforce SSH Key Authentication only.

3. Minimalism is Security: Only install the packages you absolutely need. Every extra package is a potential security hole.
