📚 Commands & Troubleshooting

1. Cross-Distro Command Quick Reference

2. Fixing Common Issues

• Permission Denied: Instead of chmod 777 (which is dangerous), I recommend using chown to fix ownership or chmod 644/755 for specific files/directories.

• SSH Connection Timeout: Check the firewall (sudo ufw status or sudo firewall-cmd --list-all) and ensure Port 22 is open. Verify the sshd service is running: sudo systemctl status ssh.

• Disk Space Full: Use du -sh /* | sort -h to find which directory is consuming space. Often, /var/log or old package caches are the culprits. Use sudo apt clean or sudo dnf clean all to free up space.

💡 Tips for a Successful Server Setup

1. Use SSH Keys: Always disable password authentication in /etc/ssh/sshd_config and use SSH keys for login.

2. Separate Partitions: Keep /var, /home, and / on separate partitions to prevent a log overflow from crashing the entire system.

3. Minimalism: Only install the packages you absolutely need. Fewer packages mean a smaller attack surface.

4. Automated Backups: Never rely on manual backups. I implement automated, off-site, encrypted backups from day one.
