1 # Phase 6.1: MacBook 2 Connectivity Findings 2 3 **Date**: November 12, 2025 4 **Status**: đ **IN PROGRESS** 5 **Repository**: rad:z2s159BoUPWefbmtu6s5DV5vvxymy (PRIVATE) 6 7 --- 8 9 ## Executive Summary 10 11 Phase 6.1 investigated and addressed MacBook 2 connectivity issues in the Auxo Radicle multi-node network. Two diagnostic and fix scripts were created, and the root cause was identified. 12 13 **Key Findings**: 14 - â Tailscale network layer working perfectly 15 - â MacBook 1 Radicle node fully functional 16 - â ī¸ MacBook 2 Radicle port (8776) not reachable 17 - â Configuration on both nodes correct 18 19 **Root Cause**: MacBook 2's Radicle node is either: 20 1. Not running 21 2. Listening on localhost only (127.0.0.1) instead of all interfaces (0.0.0.0) 22 3. Blocked by firewall 23 24 --- 25 26 ## Network Topology 27 28 ### Current Setup 29 ``` 30 âââââââââââââââââââââââââââââââââââââââââââââââââââââââââââ 31 â Tailscale Mesh Network â 32 â (100.64.0.0/10) â 33 â â 34 â ââââââââââââââââââââ ââââââââââââââââââââ â 35 â â MacBook 1 â â MacBook 2 â â 36 â â (pauxo) ââââââââēâ (pauxo2) â â 37 â â â FAIL â â â 38 â â 100.97.158.51 â â 100.98.36.92 â â 39 â â â â â â 40 â â â Port 8776 OK â â â Port 8776 â â 41 â â â Node Running â â â Node Status? â â 42 â ââââââââââââââââââââ ââââââââââââââââââââ â 43 â â 44 âââââââââââââââââââââââââââââââââââââââââââââââââââââââââââ 45 ``` 46 47 ### Node Details 48 | Node | Alias | Tailscale IP | Node ID | Status | 49 |------|-------|--------------|---------|--------| 50 | MacBook 1 | pauxo | 100.97.158.51 | z6Mkg5vF4xDYJ2849B1hTUSP9tCpWQpW9gJyB7Rr7PvNMSQ8 | â Working | 51 | MacBook 2 | pauxo2 | 100.98.36.92 | z6MkrUDca8va5fKBjtRscbvqxkfeX4ZCdx5kWZLS4Fk68z6N | â ī¸ Port Unreachable | 52 53 --- 54 55 ## Diagnostic Results 56 57 ### MacBook 1 (pauxo) - Test Results 58 59 | Test | Status | Details | 60 |------|--------|---------| 61 | 1.

MacBook 2 Port Unreachable â ī¸ CRITICAL 229 230 **Impact**: High - Prevents multi-node sync 231 **Status**: Identified, pending fix on MacBook 2 232 **Next Steps**: 233 1. Access MacBook 2 234 2. Run `scripts/setup/fix-macbook2-connectivity.sh` 235 3. Verify port listening with `lsof -i :8776` 236 4. Check node logs if issues persist 237 238 ### 2. Sync Status Command Timeout â ī¸ MINOR 239 240 **Impact**: Low - Diagnostic tool issue, not functional issue 241 **Status**: Known limitation 242 **Workaround**: Use timeout with rad sync commands 243 **Fix**: Already implemented in scripts (5-second timeout) 244 245 ### 3. System Sleep May Interrupt Connections âšī¸ INFO 246 247 **Impact**: Medium - May cause intermittent connection drops 248 **Status**: Documented 249 **Recommendation**: Disable sleep on seed nodes 250 **Fix** (optional): 251 ```bash 252 # Disable sleep when plugged in 253 sudo pmset -c sleep 0 254 ``` 255 256 --- 257 258 ## Verification Steps 259 260 ### Once MacBook 2 is Fixed 261 262 **Step 1: Verify Port Accessibility** 263 ```bash 264 # On MacBook 1 265 nc -z 100.98.36.92 8776 && echo "â Port reachable" || echo "â Port unreachable" 266 ``` 267 268 **Step 2: Test Private Repo Clone** 269 ```bash 270 # On MacBook 2 271 rad clone rad:z2s159BoUPWefbmtu6s5DV5vvxymy --seed z6Mkg5vF4xDYJ2849B1hTUSP9tCpWQpW9gJyB7Rr7PvNMSQ8 272 ``` 273 274 **Step 3: Verify Bidirectional Sync** 275 ```bash 276 # On MacBook 1 277 cd auxo-radicle-infrastructure 278 echo "test" > test-sync.txt 279 git add test-sync.txt 280 git commit -m "Test sync" 281 git push rad main 282 283 # On MacBook 2 (wait 30 seconds) 284 cd auxo-radicle-infrastructure 285 git pull rad main 286 ls test-sync.txt # Should exist 287 ``` 288 289 **Step 4: Verify Node Sees Each Other** 290 ```bash 291 # On MacBook 1 292 rad sync status | grep pauxo2 293 294 # On MacBook 2 295 rad sync status | grep pauxo 296 ``` 297 298 --- 299 300 ## Configuration Reference 301 302 ### Correct ~/.radicle/config.json 303 304 ```json 305 { 306 "node": { 307 "alias": "pauxo2", 308 "listen": ["0.0.0.0:8776"], // â Critical: Listen on all interfaces 309 "externalAddresses": [ 310 "100.98.36.92:8776" // Tailscale IP 311 ], 312 "preferredSeeds": [ 313 // Remote node 314 { 315 "id": "z6Mkg5vF4xDYJ2849B1hTUSP9tCpWQpW9gJyB7Rr7PvNMSQ8", 316 "addrs": ["100.97.158.51:8776"] 317 }, 318 // Public seeds 319 { 320 "id": "z6MkrLMMsiPWUcNPHcRajuMi9mDfYckSoJyPwwnknocNYPm7", 321 "addrs": ["iris.radicle.xyz:8776"] 322 } 323 ], 324 "seedingPolicy": { 325 "default": "allow", 326 "scope": "followed" 327 } 328 } 329 } 330 ``` 331 332 **Key Points**: 333 - `listen`: Must be `0.0.0.0:8776` to accept external connections 334 - `externalAddresses`: Must include Tailscale IP 335 - `preferredSeeds`: Must include remote Tailscale node 336 337 --- 338 339 ## Lessons Learned 340 341 1. **Process Name Truncation**: `pgrep -f "rad-node"` doesn't work; process shows as `radicle-n` 342 - Solution: Use `pgrep -f "radicle-node"` or `lsof -i :8776` 343 344 2. **Rad Commands Can Hang**: Commands like `rad sync status` can timeout 345 - Solution: Always use `timeout 5 rad ...` in scripts 346 347 3. **Listen Interface Critical**: Node must listen on `0.0.0.0`, not `127.0.0.1` 348 - Verify with: `lsof -i :8776 | grep LISTEN` 349 350 4. **Tailscale Network Reliable**: Network layer working perfectly 351 - Focus on application-level configuration 352 353 5. **Bidirectional Setup Required**: Both nodes must follow each other 354 - Script now handles this automatically 355 356 --- 357 358 ## Performance Metrics 359 360 ### Diagnostic Script 361 - **Execution Time**: ~10-15 seconds 362 - **Tests**: 10 comprehensive checks 363 - **Success Rate**: 8/10 passing on MacBook 1 364 365 ### Fix Script 366 - **Execution Time**: ~5-10 seconds 367 - **Steps**: 6 automated fixes 368 - **Success Rate**: 5/6 (remote port issue requires MacBook 2 access) 369 370 --- 371 372 ## Next Steps 373 374 ### Immediate (Phase 6.1 Completion) 375 1. â Create diagnostic script 376 2. â Create fix script 377 3. âŗ Access MacBook 2 378 4. âŗ Run fix script on MacBook 2 379 5. âŗ Verify port 8776 reachable 380 6. âŗ Test private repo clone 381 7. âŗ Document resolution 382 383 ### Future (Phase 6.2) 384 1. Add MacBook 3 to network 385 2. Test 3-way sync 386 3. Automate health monitoring 387 4. Set up connection keepalive 388 389 --- 390 391 ## Related Documentation 392 393 - [Tailscale Network Topology](./setup/tailscale-network-topology.md) 394 - [MacBook 2 Setup History](./setup/macbook2-complete-setup.md) 395 - [Phase 5 Monitoring](./phase5-completion.md) 396 - [Main Roadmap](../RADICLE_DEVELOPMENT_ROADMAP.md) 397 398 --- 399 400 ## Scripts Reference 401 402 ### Quick Commands 403 404 **On MacBook 1**: 405 ```bash 406 # Diagnostic 407 ./scripts/setup/macbook2-diagnostic.sh 408 409 # Fix connectivity 410 ./scripts/setup/fix-macbook2-connectivity.sh 411 412 # Test remote port 413 nc -z 100.98.36.92 8776 414 ``` 415 416 **On MacBook 2** (when accessible): 417 ```bash 418 # Fix connectivity 419 ./scripts/setup/fix-macbook2-connectivity.sh 420 421 # Check port listening 422 lsof -i :8776 | grep LISTEN 423 424 # Check node logs 425 rad node logs | tail -50 426 427 # Test connection to MacBook 1 428 nc -z 100.97.158.51 8776 429 ``` 430 431 --- 432 433 **Status**: Phase 6.1 scripts created and tested on MacBook 1.
