+# Session Log: 2026-04-14 - GuruRMM Tunnel Testing & Authentication Fix
+
+## Session Summary
+
+Continued from previous context-limited session. Primary accomplishments:
+1. Fixed corrupted admin password hash in production database
+2. Successfully tested all 3 tunnel API endpoints with live agents
+3. Verified Phase 1 tunnel infrastructure is production-ready
+4. Confirmed 2 of 6 agents online and running v0.6.0 with tunnel support
+
+**Key Decision:** Created standalone Rust utility to generate Argon2 password hashes rather than exposing password in database UPDATE statements or server logs.
+
+**Problems Solved:**
+- Admin password hash was only 36 characters (corrupted) - needed to be 97 chars for Argon2id
+- Special characters in password caused JSON parsing issues - used environment variable instead
+- SSH authentication failing - used sshpass with password from 1Password
+
+## Credentials & Authentication
+
+### GuruRMM Server (172.16.3.30)
+- **Admin Email:** admin@azcomputerguru.com
+- **Admin Password:** GuruRMM2025
+- **SSH User:** azcomputerguru
+- **SSH Password:** (stored in 1Password: op://Infrastructure/GuruRMM Server/password)
+- **PostgreSQL Database:** gururmm
+- **PostgreSQL User:** gururmm
+- **PostgreSQL Password:** (stored in 1Password: op://Infrastructure/GuruRMM Server/PostgreSQL Password)
+- **PostgreSQL Connection:** postgres://gururmm:[password]@172.16.3.30:5432/gururmm
+- **JWT Secret:** (stored in 1Password: op://Infrastructure/GuruRMM Server/JWT Secret)
+
+### 1Password References
+All credentials stored in vault: `Infrastructure/GuruRMM Server`
+- Access via: `op read "op://Infrastructure/GuruRMM Server/[field]"`
+- Fields: username, password, PostgreSQL User, PostgreSQL Password, Admin Email, Admin Password, JWT Secret
+
+### Password Hash Utility
+Created `/tmp/hash_password` (Rust binary) to generate Argon2id hashes:
+```bash
+/tmp/target/release/hash_password "password_here"
+# Output: $argon2id$v=19$m=19456,t=2,p=1$...[97 chars total]
+```
+
+## Infrastructure & Servers
+
+### GuruRMM Server (172.16.3.30)
+- **OS:** Ubuntu 22.04 LTS
+- **Server Binary:** /opt/gururmm/gururmm-server (v0.6.0)
+- **Server Port:** 3001 (internal)
+- **Public URL:** https://rmm-api.azcomputerguru.com (via Cloudflare Tunnel)
+- **Environment:** /opt/gururmm/.env
+- **Service:** gururmm-server.service (systemd, PID 944198)
+- **Logs:** `journalctl -u gururmm-server`
+
+### Database Schema Changes
+Migration 010_tunnel_sessions.sql created two tables:
+- `tech_sessions` - Tunnel session tracking
+- `tunnel_audit` - Audit log for tunnel operations
+
+Unique constraint on tech_sessions prevents duplicate active sessions per tech+agent pair.

+## Commands & Outputs
+
+### Fix Admin Password Hash
+
+1. **Compile password hasher utility:**
+```bash
+cd /tmp
+cat > Cargo.toml << 'EOF'
+[package]
+name = "hash_password"
+version = "0.1.0"
+edition = "2021"
+
+[dependencies]
+argon2 = { version = "0.5", features = ["password-hash"] }
+rand_core = { version = "0.6", features = ["getrandom"] }
+
+[[bin]]
+name = "hash_password"
+path = "hash_password.rs"
+EOF
+
+cargo build --release --bin hash_password
+```
+
+2. **Generate password hash:**
+```bash
+ADMIN_PASS=$(op read "op://Infrastructure/GuruRMM Server/Admin Password")
+NEW_HASH=$(/tmp/target/release/hash_password "${ADMIN_PASS}")
+# Output: $argon2id$v=19$m=19456,t=2,p=1$lipjGjdBtTk59L9A5OEXsQ$PGEPO0CGKm4W0WC2Clql4+8EvEyi89hgtkC6quL9Tec
+```
+
+3. **Update database:**
+```bash
+SSH_USER=$(op read "op://Infrastructure/GuruRMM Server/username")
+SSH_PASS=$(op read "op://Infrastructure/GuruRMM Server/password")
+PGPASS=$(op read "op://Infrastructure/GuruRMM Server/PostgreSQL Password")
+
+printf "UPDATE users SET password_hash = %s WHERE email = 'admin@azcomputerguru.com';" "'${NEW_HASH}'" | \
+sshpass -p "${SSH_PASS}" ssh -o StrictHostKeyChecking=no ${SSH_USER}@172.16.3.30 \
+  "PGPASSWORD='${PGPASS}' psql -h localhost -U gururmm -d gururmm"
+# Output: UPDATE 1
+```
+
+4. **Verify login:**
+```bash
+curl -s http://172.16.3.30:3001/api/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"email":"admin@azcomputerguru.com","password":"GuruRMM2025"}'
+# Output: {"token":"eyJ0eXAiOiJKV1QiLCJhbGci...","user":{...}}
+```
+
+### Test Tunnel API Endpoints
+
+**Authentication:**
+```bash
+ADMIN_PASS=$(op read "op://Infrastructure/GuruRMM Server/Admin Password")
+TOKEN=$(curl -s http://172.16.3.30:3001/api/auth/login \
+  -H "Content-Type: application/json" \
+  -d "{\"email\":\"admin@azcomputerguru.com\",\"password\":\"${ADMIN_PASS}\"}" | \
+  python3 -c "import sys, json; print(json.load(sys.stdin)['token'])")
+```
+
+**Test 1: Open Tunnel**
+```bash
+curl -s http://172.16.3.30:3001/api/v1/tunnel/open \

+    "last_activity": "2026-04-15T03:20:28.552818+00:00"
+}
+```
+
+**Test 3: Close Tunnel**
+```bash
+curl -s http://172.16.3.30:3001/api/v1/tunnel/close \
+  -H "Authorization: Bearer ${TOKEN}" \

+```
+
+**Server Logs (journalctl):**
+```
+Apr 15 03:20:28 - POST /api/v1/tunnel/open - 200 (12ms)
+Apr 15 03:20:34 - GET /api/v1/tunnel/status/57b408b7... - 200 (3ms)
+Apr 15 03:20:42 - POST /api/v1/tunnel/close - 200 (9ms)
+Apr 15 03:20:42 - GET /api/v1/tunnel/status/57b408b7... - 403 (2ms) [session closed]
+```
+
+## Configuration Changes
+
+### Password Hash Utility Source
+Created `/tmp/hash_password.rs`:
+```rust
+use argon2::{
+    password_hash::{rand_core::OsRng, PasswordHasher, SaltString},
+    Argon2,
+};
+
+fn main() {
+    let args: Vec<String> = std::env::args().collect();
+    if args.len() != 2 {
+        eprintln!("Usage: {} <password>", args[0]);
+        std::process::exit(1);
+    }
+
+    let password = &args[1];
+    let salt = SaltString::generate(&mut OsRng);
+    let argon2 = Argon2::default();
+
+    match argon2.hash_password(password.as_bytes(), &salt) {
+        Ok(hash) => println!("{}", hash),
+        Err(e) => {
+            eprintln!("Error hashing password: {}", e);
+            std::process::exit(1);
+        }
+    }
+}
+```
+
+### Database - users table
+**Before fix:**
+- Admin password_hash: 36 characters (corrupted/truncated)
+- Status: Login failing with "Invalid credentials"
+
+**After fix:**
+- Admin password_hash: 97 characters (proper Argon2id format)
+- Status: Login successful, JWT token generation working
+
+## API Endpoints Tested
+
+All endpoints working correctly:
+
+| Method | Endpoint | Status | Notes |
+|--------|----------|--------|-------|
+| POST | /api/auth/login | 200 | Returns JWT token + user object |
+| POST | /api/v1/tunnel/open | 200 | Creates active tunnel session |
+| GET | /api/v1/tunnel/status/:id | 200 | Returns session details |
+| POST | /api/v1/tunnel/close | 200 | Closes tunnel, sets status=closed |
+| GET | /api/v1/tunnel/status/:id (closed) | 403 | Proper error for closed session |
+
+## Pending/Incomplete Tasks
+
+### SL-SERVER Update Issue
+**Status:** Agent stuck in "pending" update state
+- Update downloaded to /tmp/gururmm-agent-0.6.0
+- Binary installed but service didn't restart
+- Running old v0.5.1 code without rollback watchdog
+- **Action Required:** Manual service restart on SL-SERVER machine
+- **Command:** `sudo systemctl restart gururmm-agent` (or Windows equivalent)
+
+### Next Steps for Tunnel Implementation
+
+**Phase 1 Complete:**
+- ✅ REST API endpoints (open, close, status)
+- ✅ Database schema (tech_sessions, tunnel_audit)
+- ✅ Agent tunnel mode state machine
+- ✅ WebSocket protocol messages (TunnelOpen, TunnelClose, TunnelReady, TunnelData)
+- ✅ Session ownership validation
+- ✅ Production deployment and testing
+
+**Phase 2 - Channel Implementation (Not Started):**
+- [ ] Terminal channel (shell command execution)
+- [ ] File channel (file upload/download)
+- [ ] Registry channel (Windows registry access)
+- [ ] Service channel (Windows service management)
+- [ ] WebSocket data forwarding between tech and agent
+- [ ] Dashboard UI for tunnel management
+
+**Phase 3 - Production Hardening (Not Started):**
+- [ ] Rate limiting on tunnel operations
+- [ ] Session timeout enforcement
+- [ ] Concurrent session limits per tech
+- [ ] Audit log cleanup/archival
+- [ ] Metrics collection (session duration, data transferred)
+- [ ] Alert on suspicious tunnel activity

+### Previous Session Work
+This session continued from context-limited conversation covering:
+1. Tunnel implementation (Phase 1 complete)
+2. Critical update bug fixes (4 bugs fixed in v0.6.0)
+3. Agent binary build and deployment
+4. Cloudflare Tunnel configuration for rmm-api.azcomputerguru.com
+5. Agent connectivity restoration (2 online after WAF skip rule)
+6. Merged feature/real-time-tunnel to main branch
+
+### Key Code Files
+- `projects/msp-tools/guru-rmm/server/src/api/tunnel.rs` - Tunnel REST API (231 lines)
+- `projects/msp-tools/guru-rmm/server/src/db/tunnel.rs` - Tunnel database ops (151 lines)

+- `projects/msp-tools/guru-rmm/agent/src/tunnel/mod.rs` - Agent tunnel manager (276 lines)
+- `projects/msp-tools/guru-rmm/agent/src/updater/mod.rs` - Update system with critical fixes
+
+## Technical Notes
+
+### Argon2id Password Hashing
+- Algorithm: Argon2id (hybrid mode)
+- Memory: 19456 KiB
+- Iterations: 2
+- Parallelism: 1
+- Output: 97-character hash string
+- Format: `$argon2id$v=19$m=19456,t=2,p=1$[salt]$[hash]`
+
+### Password Hash Corruption Root Cause
+Unknown - hash was truncated to 36 characters (likely shell/SQL escaping issue during manual operation).
+Fixed by using proper SQL escaping with printf and stdin pipe to psql.
+
+### Tunnel Session Lifecycle
+1. Tech opens tunnel via POST /api/v1/tunnel/open
+2. Server creates tech_session record, sends TunnelOpen via WebSocket
+3. Agent receives TunnelOpen, transitions to Tunnel mode, sends TunnelReady
+4. Tech can now send channel operations (Terminal, File, Registry, Service)
+5. Tech closes tunnel via POST /api/v1/tunnel/close
+6. Server updates tech_session.status='closed', sends TunnelClose via WebSocket
+7. Agent receives TunnelClose, transitions back to Heartbeat mode
+
+### Session Ownership Validation
+- Each tunnel session belongs to one tech (user_id in JWT)
+- Only the session owner can view status or close session
+- Returns 403 "Session not found or not owned by user" for unauthorized access
+- Prevents cross-tech session hijacking in multi-tenant environment
+
+## Success Metrics
+
+**Authentication:**
+- ✅ Admin login working with GuruRMM2025 password
+- ✅ JWT token generation successful
+- ✅ Token validated by protected endpoints
+
+**Tunnel API:**
+- ✅ 3/3 endpoints returning correct status codes
+- ✅ Session creation and tracking working
+- ✅ Ownership validation enforced
+- ✅ Proper cleanup on session close
+
+**Agent Connectivity:**
+- ✅ 2 agents online (33% of fleet)
+- ✅ Both online agents running v0.6.0 with tunnel support
+- ✅ WebSocket connections stable through Cloudflare Tunnel
+
+**Infrastructure:**
+- ✅ Production server running v0.6.0 (commit c7c8317)
+- ✅ Database migrations applied (up to 010)
+- ✅ Cloudflare Tunnel routing working (rmm-api.azcomputerguru.com)
+- ✅ WAF skip rule configured for WebSocket connections
