# GNS3 Packet Capture Start and stop packet captures on links in GNS3 projects. Capture network traffic for analysis and troubleshooting. ## When to Use - Troubleshooting network connectivity issues in a lab - Capturing traffic for analysis with Wireshark - Verifying routing protocol exchanges (OSPF, BGP, etc.) - Debugging application traffic - Learning about network protocols - Validating QoS or security policies ## MCP Server - **Command**: `python3 -u mcp-servers/gns3-mcp-server/gns3_mcp_server.py` (stdio transport) - **Requires**: `GNS3_URL`, `GNS3_USER`, `GNS3_PASSWORD` environment variables ## Available Tools | Tool | Parameters | What It Does | |------|------------|--------------| | `gns3_start_capture` | project_id, link_id, capture_file_name? | Start packet capture on a link | | `gns3_stop_capture` | project_id, link_id | Stop packet capture and finalize PCAP file | | `gns3_get_capture` | project_id, link_id | Get capture file path and stream URL | ## Workflow Examples ### Capture Traffic for Analysis ```bash # First, identify the link to capture "List all links in routing-test" # Start capture on the link between router1 and router2 "Start capturing traffic on link abc123 in routing-test" # Generate some traffic (ping, routing updates, etc.) # ... # Stop capture when done "Stop the capture on link abc123 in routing-test" # Get the PCAP file location "Get capture info for link abc123 in routing-test" ``` ### Custom Capture Filename ```bash # Start cap...
