## 💡 **Usage Examples**

### **System Information**
```python
# Check system capabilities
wireshark_system_info(info_type="all")
# → Returns interfaces, capabilities, server status
```

### **Live Packet Capture**
```python  
# Capture HTTP traffic for 30 seconds
wireshark_live_capture(
    interface="eth0", 
    duration=30, 
    filter="tcp port 80",
    max_packets=1000
)
# → Returns captured packets with analysis
```

### **PCAP Analysis**
```python
# Comprehensive PCAP analysis
wireshark_analyze_pcap(
    filepath="/path/to/capture.pcap",
    analysis_type="comprehensive" 
)
# → File info, protocols, security analysis
```

### **Filter Generation**
```python
# Generate filter from natural language
wireshark_generate_filter(
    description="Show all HTTP traffic from 192.168.1.0/24",
    complexity="intermediate"
)
# → Returns optimized Wireshark filter
```

### **PCAP Operations**
```python
# Split large PCAP by time
wireshark_pcap_time_slice(
    input_file="/path/to/large.pcap",
    start_time="2025-01-01T10:00:00",
    end_time="2025-01-01T11:00:00"
)
# → Creates time-sliced PCAP file

# Merge multiple PCAPs
wireshark_pcap_merger(
    input_files=["file1.pcap", "file2.pcap"],
    output_file="merged.pcap",
    sort_chronologically=true
)
# → Creates chronologically sorted merged file
```

### **Security Analysis**
```python
# Threat detection
wireshark_threat_detector(
    input_file="/path/to/suspicious.pcap",
    detection_mode="comprehensive",
    sensitivity="high"
)
# → Threat scores, anomalies, behavioral analysis

# DNS tunneling detection
wireshark_dns_analyzer(
    input_file="/path/to/capture.pcap",
    analysis_type="comprehensive",
    detect_tunneling=true
)
# → DNS patterns, suspicious domains, entropy analysis
```

## 🔧 **Expected Outputs**

### **Structured JSON Results**
All tools return well-structured JSON with:
- **Status indicators** (✅ Success, ❌ Error)
- **Rich metadata** (file sizes, timestamps, statistics)  
- **Analysis results** (protocols, conversations, threats)
- **Recommendations** (filter suggestions, security insights)

### **File Operations**
PCAP manipulation tools create properly formatted files:
- Time-sliced captures with precise timestamps
- Split files with organized naming conventions
- Merged files with chronological packet ordering
- Converted files maintaining packet integrity

### **Security Intelligence** 
Advanced analysis provides:
- **Threat scores** (0-100 risk assessment)
- **Anomaly detection** (statistical analysis)
- **Pattern recognition** (attack signatures)
- **Behavioral analysis** (network health indicators)

## 🚨 **Troubleshooting**

### **Permission Issues (Common)**
```bash
# Linux: Set capabilities
sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/dumpcap
sudo usermod -a -G wireshark $USER

# macOS: Run Wireshark as admin once
sudo /Applications/Wireshark.app/Contents/MacOS/Wireshark

# Windows: Run as Administrator
```

### **Tool Not Found**
- Ensure Wireshark is installed and in PATH
- Check `wireshark_validate_setup` tool for missing dependencies
- Verify configuration paths in Claude Desktop config

### **No Packets Captured**
- Check interface permissions with `wireshark_system_info`  
- Verify network traffic exists on selected interface
- Try different interface (eth0, wlan0, any)
