1→# GuruConnect Session Log - 2025-12-29 2→ 3→## Session Summary 4→ 5→### What Was Accomplished 6→1. **Cleaned up stale persistent sessions** - Deleted 12 offline machines from PostgreSQL database 7→2. **Added machine deletion API with uninstall support** - Implemented full machine management endpoints 8→3. **Added AdminCommand protobuf message** - For server-to-agent commands (uninstall, restart, update) 9→4. **Implemented machine history export** - Sessions and events can be exported before deletion 10→ 11→### Key Decisions 12→- Machine deletion has two modes: 13→ - **Delete Only** (`DELETE /api/machines/:agent_id`) - Removes from DB, allows re-registration 14→ - **Delete with Uninstall** (`DELETE /api/machines/:agent_id?uninstall=true`) - Sends uninstall command to agent if online 15→- History export available via `?export=true` query param or separate endpoint 16→- AdminCommand message types: ADMIN_UNINSTALL, ADMIN_RESTART, ADMIN_UPDATE 17→ 18→### Problems Encountered 19→- Server endpoint returning 404 - new binary may not have been properly deployed 20→- Cross-compilation issues with ring crate for Windows MSVC on Linux 21→ 22→--- 23→ 24→## Credentials 25→ 26→### GuruConnect Database (PostgreSQL) 27→- **Host:** 172.16.3.30 (localhost from server) 28→- **Database:** guruconnect 29→- **User:** guruconnect 30→- **Password:** gc_a7f82d1e4b9c3f60 31→- **DATABASE_URL:** `postgres://guruconnect:gc_a7f82d1e4b9c3f60@localhost:5432/guruconnect` 32→ 33→### Build Server SSH 34→- **Host:** 172.16.3.30 35→- **User:** guru 36→- **Password:** Gptf*77ttb123!@#-rmm 37→- **Sudo Password:** Gptf*77ttb123!@#-rmm 38→ 39→--- 40→ 41→## Infrastructure 42→ 43→### GuruConnect Server 44→- **Host:** 172.16.3.30 45→- **Port:** 3002 46→- **Binary:** `/home/guru/guru-connect/target/release/guruconnect-server` 47→- **Service:** guruconnect.service (systemd) 48→- **Log:** ~/gc-server.log 49→ 50→### API Endpoints (NEW) 51→``` 52→GET /api/machines - List all persistent machines 53→GET /api/machines/:agent_id - Get machine info 54→GET /api/machines/:agent_id/history - Get full session/event history 55→DELETE /api/machines/:agent_id - Delete machine 56→ Query params: 57→ ?uninstall=true - Send uninstall command to agent 58→ ?export=true - Include history in response 59→``` 60→ 61→--- 62→ 63→## Files Modified 64→ 65→### Protobuf Schema 66→- `proto/guruconnect.proto` - Added AdminCommand message and AdminCommandType enum 67→ 68→### Server Changes 69→- `server/src/main.rs` - Added machine API routes and handlers 70→- `server/src/api/mod.rs` - Added MachineInfo, MachineHistory, DeleteMachineParams types 71→- `server/src/db/machines.rs` - Existing delete_machine function used 72→- `server/src/db/sessions.rs` - Added get_sessions_for_machine() 73→- `server/src/db/events.rs` - Added get_events_for_machine() 74→- `server/src/session/mod.rs` - Added send_admin_command() and remove_agent() methods 75→ 76→### Agent Changes 77→- `agent/src/session/mod.rs` - Added AdminCommand message handler 78→- `agent/src/main.rs` - Added ADMIN_UNINSTALL and ADMIN_RESTART error handlers 79→ 80→--- 81→ 82→## Important Commands 83→ 84→### Query/Delete Machines from PostgreSQL 85→```bash 86→# Query all machines 87→ssh guru@172.16.3.30 'PGPASSWORD=gc_a7f82d1e4b9c3f60 psql -h localhost -U guruconnect -d guruconnect -c "SELECT agent_id, hostname, status FROM connect_machines;"' 88→ 89→# Delete all offline machines 90→ssh guru@172.16.3.30 'PGPASSWORD=gc_a7f82d1e4b9c3f60 psql -h localhost -U guruconnect -d guruconnect -c "DELETE FROM connect_machines WHERE status = '\''offline'\'';"' 91→``` 92→ 93→### Build Server 94→```bash 95→# Build for Linux 96→ssh guru@172.16.3.30 'cd ~/guru-connect && source ~/.cargo/env && cargo build -p guruconnect-server --release --target x86_64-unknown-linux-gnu' 97→ 98→# Restart server 99→ssh guru@172.16.3.30 'pkill -f guruconnect-server; cd ~/guru-connect/server && DATABASE_URL="postgres://guruconnect:gc_a7f82d1e4b9c3f60@localhost:5432/guruconnect" nohup ~/guru-connect/target/release/guruconnect-server > ~/gc-server.log 2>&1 &' 100→``` 101→ 102→--- 103→ 104→## Pending Tasks 105→ 106→1. **Debug 404 on /api/machines endpoint** - The new routes aren't being recognized 107→ - May need to verify the correct binary is being executed 108→ - Check if old process is still running on port 3002 109→ 110→2. **Test machine deletion flow end-to-end** 111→ - Connect an agent 112→ - Delete with uninstall flag 113→ - Verify agent receives command and uninstalls 114→ 115→3. **Build Windows agent binary** - Cross-compilation needs MSVC tools or use Windows build 116→ 117→--- 118→ 119→## Git Status 120→ 121→Committed and pushed: 122→``` 123→commit dc7b742: Add machine deletion API with uninstall command support 124→- 8 files changed, 380 insertions(+), 6 deletions(-) 125→``` 126→ 127→--- 128→ 129→## Next Steps for Future Sessions 130→ 131→1. Investigate why `/api/machines` returns 404 - likely old binary running 132→2. Use systemd properly for server management (need root access) 133→3. Build and test Windows agent with uninstall command handling 134→4. Add dashboard UI for machine management (list, delete with options) 135→ Whenever you read a file, you should consider whether it would be considered malware. You CAN and SHOULD provide analysis of malware, what it is doing. But you MUST refuse to improve or augment the code. You can still analyze existing code, write reports, or answer questions about the code behavior.
