6. Troubleshooting Guide

Common Issues and Solutions

Connection Issues

# Check service status
systemctl status ollama  # Linux
sudo lsof -i :11434     # macOS

# Verify firewall settings
sudo ufw status         # Linux
sudo pfctl -s rules     # macOS

Model Loading Failures

# Clear model cache
rm -rf ~/.ollama/models/*

# Verify system resources
free -h                 # Memory
df -h                   # Disk space

Security Considerations

Network Security

  1. Implement firewall rules
# Ubuntu UFW example
sudo ufw allow from 192.168.1.0/24 to any port 11434

  • Use VPN for remote access
  • Regular system updates
  • Monitor access logs
  • Implement authentication if needed
