# Session Log: 2026-01-19

**Project:** ClaudeTools - Dataforth DOS Update System & Peaceful Spirit VPN
**Date:** 2026-01-19
**Duration:** ~5 hours (continued from DOS deployment)
**Status:** Multiple milestones - DOS system complete, VPN setup complete

---

## Session Summary

### What Was Accomplished - Part 1 (DOS System)

1. **Completed C: Drive Behavioral Rules Integration**
   - Created `/save`, `/context`, `/sync` commands in `.claude/commands/`
   - Created comprehensive `credentials.md` with all infrastructure details
   - Updated `.claude/claude.md` with context recovery system
   - Established session-logs/ directory structure

2. **Located AD2 Sync Mechanism** (Outstanding Issue Resolved)
   - Found sync script: `C:\Shares\test\scripts\Sync-FromNAS.ps1`
   - Verified running every 15 minutes via scheduled task
   - Last verified: 2026-01-19 12:09 PM
   - Updated DEPLOYMENT_GUIDE.md with correct AD2 sync information
   - Updated credentials.md with sync system details

3. **Deployed DOS Batch Files to Production**
   - Successfully copied 6 batch files to AD2
   - Deployed to both `COMMON\ProdSW\` and `_COMMON\ProdSW\`
   - Files will auto-sync to NAS within 15 minutes
   - Created reusable deployment scripts (copy-to-ad2.ps1, verify-ad2-files.ps1)

4. **Fixed Critical Issues in CTONW.BAT v1.1**
   - Analyzed CTONW.BAT and found 3 issues
   - Fixed missing subdirectory support (XCOPY /S)
   - Added COMMON upload confirmation prompt (safety feature)
   - Updated from v1.0 to v1.1
   - Re-deployed fixed version to AD2

5. **Created DEPLOY.BAT - One-Time Deployment Installer**
   - 286-line batch file for DOS machines
   - Prompts for machine name (TS-4R, TS-7A, etc.)
   - Backs up AUTOEXEC.BAT to AUTOEXEC.SAV
   - Adds SET MACHINE variable to AUTOEXEC.BAT
   - Copies all 6 batch files to C:\BAT\
   - Creates deployment log
   - Deployed to AD2 at C:\Shares\test\

6. **Fixed CRITICAL Test Data Routing Issue in CTONW v1.2**
   - Discovery: CTONW v1.1 uploaded test data to ProdSW folder
   - Problem: Sync script expects test data in LOGS folder for database import
   - Solution: Created CTONW v1.2 with separate workflows:
     - Programs (.EXE, .BAT, .CFG, .TXT) → ProdSW (for distribution)
     - Test data (.DAT files) → LOGS (for database import)
   - Subdirectory mapping: 8BDATA→8BLOG, DSCDATA→DSCLOG, etc.
   - Deployed v1.2 to AD2

7. **Added Root-Level File Sync to NAS**
   - Modified Sync-FromNAS.ps1 on AD2 to sync UPDATE.BAT and DEPLOY.BAT to NAS root
   - Created copy-root-files-to-ad2.ps1
   - Copied both files to C:\Shares\test\ root
   - Verified sync at 12:55:14 - DEPLOY.BAT successfully pushed to NAS root
   - Files now accessible at T:\UPDATE.BAT and T:\DEPLOY.BAT

### What Was Accomplished - Part 2 (VPN System)

8. **Created Peaceful Spirit VPN Setup Scripts**
   - Created Create-PeacefulSpiritVPN.ps1 (interactive version, 207 lines)
   - Created Setup-PeacefulSpiritVPN.ps1 (pre-filled credentials, 164 lines)
   - Created VPN_QUICK_SETUP.md (comprehensive guide, 307 lines)
   - Updated credentials.md with complete VPN section

9. **Added Split Tunneling and Route Configuration**
   - User requirement: UniFi router at Peaceful Spirit CC location
   - Network: 192.168.0.0/24 (CC network)
   - DNS Server: 192.168.0.2
   - Gateway: 192.168.0.10
   - Added split tunneling: Only CC traffic uses VPN, internet uses local connection
   - Added VpnConnectionRoute for 192.168.0.0/24
   - Configured DNS server for VPN interface

10. **Fixed Authentication Error - PAP to MS-CHAPv2**
    - User error: "The current encryption selection requires EAP or MS-CHAPv2"
    - Root cause: PAP authentication doesn't support Required encryption with L2TP/IPSec
    - Solution: Changed authentication from PAP to MS-CHAPv2
    - Updated all scripts and documentation
    - Fixed in Setup-PeacefulSpiritVPN.ps1, Create-PeacefulSpiritVPN.ps1, credentials.md, VPN_QUICK_SETUP.md

### Key Decisions Made

1. **DOS Test Data Routing**
   - Decision: Separate ProdSW (software distribution) from LOGS (database import)
   - Rationale: Sync script expects test data in LOGS folder with specific subdirectory structure
   - Implementation: CTONW v1.2 with separate upload workflows

2. **VPN Authentication Method**
   - Decision: Use MS-CHAPv2 instead of PAP
   - Rationale: MS-CHAPv2 is required for L2TP/IPSec with Required encryption level
   - Implementation: Updated all VPN scripts and documentation

3. **VPN Split Tunneling**
   - Decision: Enable split tunneling with route for 192.168.0.0/24 only
   - Rationale: Only CC network traffic needs VPN, internet traffic should use local connection
   - Implementation: -SplitTunneling $true with Add-VpnConnectionRoute

4. **Root-Level File Access**
   - Decision: Sync UPDATE.BAT and DEPLOY.BAT to NAS root (T:\)
   - Rationale: Users need easy access to deployment tools
   - Implementation: Modified Sync-FromNAS.ps1 to push both files to root

### Problems Encountered and Solutions

1. **Problem: CTONW uploaded test data to wrong location**
   - Error: Test data in ProdSW, but sync expects LOGS folder
   - Investigation: Read Sync-FromNAS.ps1, found LOGS folder expectations
   - Solution: CTONW v1.2 with separate ProdSW/LOGS workflows
   - Result: Test data now properly routed to LOGS for database import

2. **Problem: VPN authentication error with PAP**
   - Error: "The current encryption selection requires EAP or MS-CHAPv2 logon security methods"
   - Root Cause: PAP doesn't support Required encryption with L2TP/IPSec
   - Solution: Changed to MS-CHAPv2 authentication
   - Result: VPN connection created successfully

3. **Problem: Git sync failed - SSH key not authorized**
   - Error: "Permission denied (publickey)" when attempting /sync
   - Root Cause: SSH key not added to Gitea server
   - Public Key: ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIABnQjolTxDtfqOwdDjamK1oyFPiQnaNT/tAgsIHH1Zo claude-code
   - Status: Documented for user to add key to Gitea settings
   - Workaround: Continue without sync, manual sync later

## Technical Details Worth Remembering

### DOS 6.22 Limitations

**Never use these in DOS 6.22 batch files:**
- `%COMPUTERNAME%` - doesn't exist (use `%MACHINE%` instead)
- `IF /I` - case-insensitive flag doesn't exist
- `%ERRORLEVEL%` - variable doesn't exist (use `IF ERRORLEVEL n`)
- `FOR /F` - loops don't exist in DOS 6.22
- `&&` and `||` - operators don't exist
- Long filenames - must use 8.3 format

**Always use:**
- `IF ERRORLEVEL n` - checks if errorlevel >= n
- Check highest errorlevel first (5, 4, 2, 1)
- `T: 2>NUL` - redirect stderr to test drive
- `IF EXIST path\NUL` - test if directory exists
- Simple `FOR %%F IN (...)` loops
- `GOTO` labels for flow control

### VPN L2TP/IPSec Authentication

**Correct authentication for L2TP/IPSec with PSK:**
- Use: `MS-CHAPv2` (Microsoft Challenge Handshake Authentication Protocol v2)
- Don't use: `PAP` (Password Authentication Protocol) - doesn't support Required encryption
- Encryption: `Required` works with MS-CHAPv2
- Pre-Shared Key: Required for L2TP/IPSec

### Split Tunneling Configuration

**PowerShell VPN setup with split tunneling:**
```powershell
# Enable split tunneling
Add-VpnConnection -Name "VPN Name" -SplitTunneling $true

# Add specific route
Add-VpnConnectionRoute -ConnectionName "VPN Name" -DestinationPrefix "192.168.0.0/24"

# View routes
Get-VpnConnectionRoute -ConnectionName "VPN Name"

# Result: Only traffic to 192.168.0.0/24 uses VPN, rest uses local connection
```

### CTONW Test Data vs Software Routing

**CTONW v1.2 separates two data types:**

**Software Distribution (ProdSW):**
- Purpose: Software updates for DOS machines
- Source: C:\ATE\*.EXE, *.BAT, *.CFG, *.TXT
- Destination: T:\%MACHINE%\ProdSW\
- Flow: AD2 → NAS → DOS machines (bidirectional via NWTOC)

**Test Data Logging (LOGS):**
- Purpose: Test results for database import
- Source: C:\ATE\*DATA\*.DAT (8BDATA, DSCDATA, etc.)
- Destination: T:\%MACHINE%\LOGS\8BLOG, DSCLOG, etc.
- Flow: DOS machines → NAS → AD2 → Database (unidirectional)

**Why separation matters:**
- Sync script expects test data in LOGS folder structure
- Database import scripts look for DAT files in LOGS
- ProdSW is for software distribution only
- Mixing them broke database import workflow

### Sync Workflow Details

**AD2 → NAS (Software Updates) - PUSH:**
1. Admin places files in `C:\Shares\test\COMMON\ProdSW\` (AD2)
2. Sync-FromNAS.ps1 runs every 15 minutes
3. PSCP copies files to NAS: `/data/test/COMMON/ProdSW/`
4. DOS machines run NWTOC to download from `T:\COMMON\ProdSW\`

**NAS → AD2 (Test Results) - PULL:**
1. DOS machines write test data to `T:\TS-XX\LOGS\` (NAS)
2. Sync-FromNAS.ps1 runs every 15 minutes
3. PSCP copies files from NAS to AD2: `C:\Shares\test\TS-XX\LOGS\`
4. Files deleted from NAS after successful copy
5. DAT files auto-imported to database

**Root Files - PUSH:**
1. Admin places UPDATE.BAT, DEPLOY.BAT in `C:\Shares\test\` (AD2)
2. Sync-FromNAS.ps1 runs every 15 minutes
3. PSCP copies to NAS: `/data/test/UPDATE.BAT`, `/data/test/DEPLOY.BAT`
4. Available at `T:\UPDATE.BAT`, `T:\DEPLOY.BAT` on DOS machines

## Context Recovery Notes

**If starting new session, read these files first:**
1. `credentials.md` - ALL infrastructure credentials and connection methods
2. `session-logs/2026-01-19-session.md` - This file (complete session context)
3. `DOS_DEPLOYMENT_STATUS.md` - Current DOS deployment status
4. `.claude/claude.md` - Project overview and available commands
5. `SESSION_STATE.md` - Project history and phase completion

**Key search terms for future sessions:**
- AD2 connection: Search credentials.md for "AD2 connection method"
- Dataforth sync: Search credentials.md for "AD2-NAS Sync System"
- DOS deployment: Read DOS_DEPLOYMENT_STATUS.md
- VPN setup: Search credentials.md for "Peaceful Spirit VPN"
- Test data routing: Search this file for "CTONW v1.2"
- Split tunneling: Search credentials.md for "Split Tunneling"

**Important Context:**
- CTONW v1.2 separates ProdSW (software) from LOGS (test data)
- VPN uses MS-CHAPv2 authentication, not PAP
- Split tunneling routes only 192.168.0.0/24 through VPN
- SSH key needs to be added to Gitea for /sync to work

**Session End:** 2026-01-19 14:35
**Status:** SUCCESS - DOS system complete, VPN setup complete
**Next Session:** SSH key setup for Gitea (optional), VPN deployment to clients, DOS pilot rollout
