brctl create leaves the bridge administratively DOWN. Add link set up so the bridge actually forwards frames between enslaved ports. Also record Docker iptables FORWARD DROP pitfall in project memory.

GNS3 Server Project Memory
Note
: This directory stores important project-related memories and case studies, managed with the code repository.
How to record: Use the
/memoryskill to record important information to the project memory directory.
Quick Reference
- Memory directory:
.claude/memory/ - Skill file:
.claude/skills/memory/SKILL.md - Main index:
MEMORY.md(this file)
Topics
Web Wireshark Integration
- JWT Token Flow - JWT token transmission path in Web Wireshark
- Key point: UDPLink only passes through jwt_token, ultimately used by curl command inside Web Wireshark container to authenticate with GNS3 capture stream API
- Xpra HTML5 Client - Xpra HTML5 client menu control parameters for customizing the web interface
RBAC & User Isolation
- RBAC User Isolation Design — Three-step permission check design: ACE batch check → created_by filtering → resource pools
Appliance Management
- GNS3 Appliance Loading - How GNS3 loads appliance files from builtin and custom directories with priority rules
uBridge Permission
- uBridge Permission Issue - Docker containers fail to start due to missing CAP_NET_ADMIN/CAP_NET_RAW capabilities on uBridge
- Docker iptables FORWARD blocks bridge - Docker sets FORWARD chain to DROP, blocking kernel bridge forwarding;
sudo iptables -P FORWARD ACCEPTto fix
Docker Container Stop Delay
- Docker Container Stop Delay - Some containers take ~5s to stop because they don't handle SIGTERM (AlpiNet, OstinatoWireshark)
MCP Service
- MCP Service Design - MCP (Model Context Protocol) service architecture using FastMCP with SSE transport, JWT auth, 29 tools across 5 domains
- MCP Tool Description Location - Where to define MCP tool descriptions: in
@mcp.tool()functions in__init__.py, not in*_TOOLSarrays
Python Code Verification
- Import Validation - Use actual module imports (
python -c "from ... import ...") instead ofpy_compileto catch missing imports
