Basic Usenet knowledge

Understanding NZBGet Architecture

NZBGet operates efficiently through smart resource management:

NZBGet Workflow:
1. NZB file added to queue (via API, RSS, or manual)
2. Articles downloaded from Usenet servers
3. On-the-fly verification and assembly
4. Automatic par2 repair if needed
5. Archive extraction
6. Post-processing scripts execution
7. Cleanup and notification

Components:

Core Engine: C++ binary for efficiency
Web Interface: Responsive HTML5 UI
API Server: RESTful API for integrations
Extension System: Python/Bash scripts for customization

Directory Structure

Create organized directories:

# Create NZBGet directories
mkdir -p /opt/nzbget/{config,downloads/dst,downloads/inter,downloads/nzb,downloads/tmp}

# Create category-specific directories
mkdir -p /opt/nzbget/downloads/dst/{movies,tv,music,books}

# Set ownership
sudo chown -R $USER:$USER /opt/nzbget

Directory Explanation:

/opt/nzbget/config: Configuration files and scripts
/opt/nzbget/downloads/dst: Completed downloads (destination)
/opt/nzbget/downloads/inter: Intermediate processing directory
/opt/nzbget/downloads/nzb: NZB files directory
/opt/nzbget/downloads/tmp: Temporary download files

Docker Compose Configuration

Create /opt/nzbget/docker-compose.yml:

version: '3.8'

services:
  nzbget:
    image: linuxserver/nzbget:latest
    container_name: nzbget
    restart: unless-stopped
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=America/New_York
      - UMASK=022
    volumes:
      - /opt/nzbget/config:/config
      - /opt/nzbget/downloads:/downloads
      # Optional: Share with media directories
      - /media:/media
    ports:
      - 6789:6789
    # Resource limits (optional but recommended)
    deploy:
      resources:
        limits:
          memory: 512M
        reservations:
          memory: 128M

Configuration Notes:

Replace PUID and PGID with your user ID (id -u and id -g)
Update TZ to your timezone
Port 6789 is the web interface (default for NZBGet)
Memory limits ensure NZBGet stays efficient
Lower limits than SABnzbd due to efficiency

VPN Integration (optional):

version: '3.8'

Troubleshooting

Common issues and resolutions.

Downloads Not Starting

Symptoms: NZB added but stays queued

Diagnostics:

Check Status → Messages for errors
Verify server connections: Settings → News-Servers → Test
Review Status → Log for details

Solutions:

Test server credentials
Verify Usenet account active
Check firewall allowing outbound 563/119
Restart NZBGet: docker-compose restart

Slow Download Speeds

Symptoms: Not saturating bandwidth

Diagnostics:

Check Status → Statistics for server usage
Verify connection counts
Check speed limit setting

Solutions:

Increase connections per server (up to 30-50 total)
Remove speed limit: Settings → Download Queue → Speed Limit → 0
Add additional Usenet servers
Verify no bandwidth throttling active

Par2 Repair Failures

Symptoms: “Collection failed: Could not repair”

Diagnostics:

Check History for failure details
Verify par2 files downloaded
Check if content beyond retention

Solutions:

Enable extended par scan: Settings → Download Queue → Par Scan → Extended
Increase par buffer: Settings → Download Queue → Par Buffer → 64
Use backup server with longer retention
Content may be incomplete or too old

Extraction Failures

Symptoms: Unpack errors in post-processing

Diagnostics:

Check Status → Log for unpack errors
Verify disk space available
Check for password-protected archives

Solutions:

Ensure sufficient disk space (10GB+ free)
Enable unpack cleanup: Settings → Post-Processing → Unpack Cleanup → Yes
Set default password if known: Settings → Post-Processing → Unpack Passwd
Manual extraction may be required for password-protected files

Permission Issues

Symptoms: Can’t write files, import failures

Solutions:

# Fix ownership
sudo chown -R 1000:1000 /opt/nzbget

# Fix permissions
sudo chmod -R 755 /opt/nzbget/downloads

# Verify PUID/PGID in docker-compose.yml
docker-compose down
# Edit docker-compose.yml
docker-compose up -d

API Connection Issues

Symptoms: arr apps can’t connect

Solutions:

Verify credentials match
Check host accessible: curl http://nzbget:6789 from arr container
Review Settings → Security → Control IP (ensure not blocking)
Disable username/password for localhost (optional)
Check container networking

Performance Optimization

Maximize NZBGet efficiency.

Memory Optimization

Article Cache:

Optimal settings based on RAM:

512MB RAM: Article Cache = 50
1GB RAM: Article Cache = 100-150
2GB RAM: Article Cache = 200-300
4GB+ RAM: Article Cache = 300-500

Settings → Download Queue → Article Cache: 200

Write Buffer: Default (1024) is optimal for most systems.

CPU Optimization

Par Threads:

Settings → Download Queue → Par Threads: 0 (auto-detect)

Uses all available CPU cores for par2 operations.

Par Buffer:

Default: 16 MB
More RAM available: 32-64 MB
Speeds up verification and repair

Disk Optimization

Separate Directories:

Temp: Fast SSD for active downloads
Destination: HDD acceptable for completed files
Intermediate: SSD for processing

Direct Unpack: Settings → Download Queue → Direct Unpack: Yes

Unpacks while downloading instead of after.

Network Optimization

Connection Distribution:

Optimal for most providers:

Primary Server (unlimited): 20-30 connections
Backup Server: 10-15 connections
Block Account: 5-8 connections
Total: 30-50 connections

Server Priorities:

Level 0: Unlimited primary
Level 1: Backup or second unlimited
Level 2+: Block accounts and fill servers

Security Best Practices

Secure your NZBGet installation.

Authentication

Enable Strong Authentication:

Settings → Security:

Username: Complex username
Password: Strong password (20+ characters)
Authorization: Restricted

API Security:

Keep credentials secret
Don’t share in scripts (use environment variables)
Regenerate password periodically

Network Security

Restrict Access:

Settings → Security → Control IP:

127.0.0.1,192.168.1.0/24

Only allows localhost and local network.

Reverse Proxy with SSL:

Nginx configuration:

server {
    listen 443 ssl http2;
    server_name nzbget.yourdomain.com;

    ssl_certificate /etc/ssl/certs/cert.pem;
    ssl_certificate_key /etc/ssl/private/key.pem;

    location / {
        proxy_pass http://localhost:6789;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

Firewall:

# Local network only
sudo ufw allow from 192.168.1.0/24 to any port 6789

# Or specific IP
sudo ufw allow from SPECIFIC-IP to any port 6789

VPN

Route through VPN for privacy (see Docker Compose VPN section).

Backup and Restore

Protect your configuration.

Backup Configuration

Manual Backup:

cd /opt/nzbget
docker-compose down

# Backup config
tar -czf nzbget-backup-$(date +%Y%m%d).tar.gz /opt/nzbget/config

docker-compose up -d

Automated Backup:

#!/bin/bash
# /opt/scripts/backup-nzbget.sh

BACKUP_DIR="/opt/backups/nzbget"
DATE=$(date +%Y%m%d)

mkdir -p "$BACKUP_DIR"

cd /opt/nzbget
docker-compose stop nzbget

tar -czf "$BACKUP_DIR/nzbget-$DATE.tar.gz" /opt/nzbget/config

docker-compose start nzbget

# Keep 30 days
find "$BACKUP_DIR" -name "nzbget-*.tar.gz" -mtime +30 -delete

Schedule:

# Weekly on Sunday 3 AM
0 3 * * 0 /opt/scripts/backup-nzbget.sh

Restore

cd /opt/nzbget
docker-compose down

tar -xzf nzbget-backup-YYYYMMDD.tar.gz -C /

sudo chown -R 1000:1000 /opt/nzbget/config

docker-compose up -d

Advanced Features

Extend NZBGet capabilities.

API Usage

NZBGet provides comprehensive RESTful API.

Add NZB via API:

curl -u admin:password   "http://localhost:6789/jsonrpc/append"   --data '{"method":"append","params":["URL-TO-NZB.nzb"]}'

Check Status:

curl -u admin:password   "http://localhost:6789/jsonrpc/status"

Pause/Resume:

# Pause
curl -u admin:password   --data '{"method":"pausedownload"}'   "http://localhost:6789/jsonrpc"

# Resume
curl -u admin:password   --data '{"method":"resumedownload"}'   "http://localhost:6789/jsonrpc"

Custom Extensions

Create custom extension scripts.

Example: Size Validator:

#!/usr/bin/env python3
# Reject downloads over 50GB

import os
import sys

MAX_SIZE = 50 * 1024 * 1024 * 1024  # 50GB in bytes

size = int(os.environ.get('NZBNA_SIZE', '0'))

if size > MAX_SIZE:
    print(f"[WARNING] Download too large: {size/1024/1024/1024:.2f}GB")
    sys.exit(93)  # POSTPROCESS_ERROR

print("[INFO] Size validation passed")
sys.exit(93)  # POSTPROCESS_SUCCESS

Exit Codes:

93: Success
94: Failed, retry
95: Failed, no retry

Notifications

Configure completion notifications.

Email (using EMail.py extension):

Settings → Extension Scripts → EMail.py:

Enabled: Yes
