🚀 Getting Started & Fixing Issues

1. Fundamental Commands Across Distributions

While most commands are universal, package management varies. Use this quick reference:

Task	Debian/Ubuntu (apt)	RHEL/CentOS/Rocky (dnf)	Arch Linux (pacman)
Update Repos	`sudo apt update`	`sudo dnf check-update`	`sudo pacman -Sy`
Install App	`sudo apt install [pkg]`	`sudo dnf install [pkg]`	`sudo pacman -S [pkg]`
Check Logs	`journalctl -xe`	`journalctl -xe`	`journalctl -xe`
Check Disk	`df -h`	`df -h`	`df -h`

2. Fixing Common Issues 🔧

Permission Denied: Use ls -l to check ownership. Fix with sudo chown user:group filename or chmod 755 filename.
Service Won't Start: Check status with systemctl status service_name. Look for "Failed" lines.
Network Latency: Use mtr -rw [ip_address] to identify which hop is dropping packets.
Full Disk: Use du -sh /* | sort -h to find which directory is consuming space.

💡 Tips for a Successful Server Setup

I recommend following these four pillars for any new installation:

Minimal Install: Always start with the "Minimal" ISO. Only install the packages you absolutely need to reduce the attack surface.
SSH Hardening: Disable Root Login and switch to SSH Key-based authentication immediately. Change the default port 22 to a custom high port.
LVM Partitioning: Use Logical Volume Management (LVM). It allows you to resize partitions dynamically as your data grows.
Automated Time Sync: Ensure chrony or ntp is active. Accurate logs depend on perfectly synced system clocks.
