## Technical Changelog - Session 1: Security Hardening

### 1. Infrastructure Security Audit

**Objective:** Identify and document all security vulnerabilities across inherited infrastructure

**Findings:**
- 5 unauthorized/outdated user accounts across inherited servers
- Breezehost support backdoor accounts on 3 servers
- Password authentication enabled on 3 inherited servers (TX1, Panel, NC1)
- Inconsistent security policies across infrastructure
- System updates pending on all servers

**Servers with Security Issues:**
1. **TX1 Dallas** - Password auth enabled, unauthorized users present
2. **NC1 Charlotte** - Password auth enabled, unauthorized users present  
3. **Panel** - Password auth enabled, 118 pending updates
4. **Command Center** - Clean (deployed post-security model)
5. **Billing** - Clean (deployed post-security model)
6. **Ghost** - Clean but pending restart

**Audit Method:**
```bash
# User account enumeration
cat /etc/passwd | grep -v nologin | grep -v false

# SSH configuration review
grep "PasswordAuthentication" /etc/ssh/sshd_config

# System update check
apt list --upgradable
```

---

### 2. SSH Key Infrastructure Deployment

**Strategy:** Deploy SSH key authentication to all servers, disable password authentication

**SSH Key Generation:**
- Generated on local workstation (MobaXterm)
- Algorithm: RSA 4096-bit
- Passphrase: Protected
- Purpose: Unified authentication across infrastructure

**Deployment Process (Per Server):**
```bash
# Create .ssh directory
mkdir -p ~/.ssh
chmod 700 ~/.ssh

# Deploy public key
echo "ssh-rsa AAAAB3NzaC1yc2E..." > ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys

# Verify key authentication works
# (test connection with key before disabling passwords)

# Update SSH config
nano /etc/ssh/sshd_config
# Change: PasswordAuthentication yes → no
# Change: PubkeyAuthentication yes (confirm enabled)

# Backup config
cp /etc/ssh/sshd_config /etc/ssh/sshd_config.backup

# Restart SSH
systemctl restart sshd
```

**Deployment Results:**
- ✅ TX1 Dallas - SSH keys deployed, password auth disabled
- ✅ NC1 Charlotte - SSH keys deployed, password auth disabled
- ✅ Panel - SSH keys deployed, password auth disabled
- ✅ Command Center - Already using SSH keys (deployed clean)
- ✅ Billing - Already using SSH keys (deployed clean)
- ✅ Ghost - Already using SSH keys (deployed clean)

**Security Validation:**
- Tested key-based login from MobaXterm ✓
- Verified password authentication disabled ✓
- Confirmed root login with keys working ✓

---

### 3. User Account Cleanup

**Unauthorized Accounts Identified:**

**TX1 Dallas:**
- `breezehost` - Support backdoor account (password-protected)

**NC1 Charlotte:**
- `breezehost` - Support backdoor account (password-protected)
- `michael` - Old/duplicate account from inheritance

**Panel:**
- `breezehost` - Support backdoor account (password-protected)
- `architect` - Old account from previous setup

**Ghost:**
- `architect` - Non-root user (intentionally kept - security best practice)

**Removal Process:**
```bash
# Verify account exists
id USERNAME

# Remove user and home directory
userdel -r USERNAME

# Verify removal
id USERNAME  # Should show "no such user"

# Check /home cleanup
ls -la /home/  # Verify directory removed
```

**Accounts Removed:**
1. TX1 Dallas: `breezehost` ✓
2. NC1 Charlotte: `breezehost`, `michael` ✓
3. Panel: `breezehost`, `architect` ✓

**Accounts Retained:**
- Ghost: `architect` - Intentional non-root user (security best practice)

**Security Impact:**
- All Breezehost backdoor accounts removed
- All password-protected legacy accounts removed
- Only SSH key authentication remains
- Root is only admin account (except Ghost VPS)

---

### 4. System Updates & Maintenance

**Update Strategy:** Apply all pending updates, coordinate reboots to minimize downtime

**Update Scope:**

| Server | Updates Pending | Security Updates | Restart Required |
|--------|----------------|------------------|------------------|
| TX1 Dallas | 67 packages | 2 security | Yes (kernel) |
| NC1 Charlotte | 12 packages | 1 security | Yes (kernel) |
| Panel | 118 packages | 2 security | No |
| Command Center | 26 packages | 0 security | No |
| Billing | 31 packages | 1 security | No |
| Ghost | 29 packages | 1 security | Yes (kernel) |
| **TOTAL** | **283 packages** | **7 security** | **3 servers** |

**Update Process:**
```bash
# Update package lists
apt update

# Review updates
apt list --upgradable

# Apply all updates (non-interactive)
DEBIAN_FRONTEND=noninteractive apt upgrade -y

# Check if restart required
[ -f /var/run/reboot-required ] && echo "Restart needed"

# Review restart reason
cat /var/run/reboot-required.pkgs
```

**Update Results:**
- ✅ All 283 packages updated successfully
- ✅ All 7 security updates applied
- ✅ No update failures or conflicts
- ✅ All services restarted cleanly

**Kernel Updates Applied:**
- TX1 Dallas: 6.8.0-51 → 6.8.0-100
- NC1 Charlotte: 6.8.0-49 → 6.8.0-100  
- Ghost: 6.8.0-48 → 6.8.0-100

### 5. Coordinated Server Reboots

**Reboot Strategy:** Stagger reboots to maintain infrastructure availability

**Reboot Sequence:**
1. Ghost CMS (non-critical, standalone)
2. Billing (low traffic, monitoring in place)
3. TX1 Dallas (game servers - coordinated downtime)
4. NC1 Charlotte (game servers - coordinated downtime)
5. Panel (control plane - brief downtime acceptable)
6. Command Center (management - last to reboot)

**Reboot Process (Per Server):**
```bash
# Announce downtime (if applicable)
# Stop critical services (if needed)

# Initiate reboot
reboot

# Wait for server to come back online
# (monitor in IPMI/console or via ping)

# Verify services started
systemctl status [service-name]

# Verify kernel version
uname -r  # Should show 6.8.0-100

# Verify network connectivity
ping -c 3 8.8.8.8

# Test SSH access
# (connect via SSH from workstation)
```

**Reboot Results:**
- ✅ Ghost - Rebooted, kernel 6.8.0-100, all services running
- ✅ Billing - Rebooted, kernel current, Paymenter running
- ✅ TX1 Dallas - Rebooted, kernel 6.8.0-100, 6 game servers running
- ✅ NC1 Charlotte - Rebooted, kernel 6.8.0-100, 9 game servers running
- ✅ Panel - Rebooted, Pterodactyl Panel operational
- ✅ Command Center - Rebooted, all management services running

**Total Downtime:** 
- Per server: ~2-3 minutes

## Technical Changelog - Session 2: Gitea Migration

### 7. Pre-Migration Planning

**Migration Objective:** Relocate Gitea from Command Center (VPS) to TX1 Dallas (Dedicated Server)

**Rationale:**
- TX1 has massive headroom (32 vCPU, 256GB RAM, 99% idle)
- Consolidate management services on dedicated hardware
- Free up Command Center for future gateway role
- Improve performance and reliability

**Data Assessment:**
```bash
# Command Center (Source)
du -sh /var/lib/gitea/
# Result: 13MB total data

du -sh /var/lib/gitea/repositories/
# Result: 11MB (Git repository data)

du -sh /var/lib/gitea/data/gitea.db
# Result: 2MB (SQLite database)

# File count
find /var/lib/gitea -type f | wc -l
# Result: 174 files
```

**Migration Components:**
1. Gitea binary (`/usr/local/bin/gitea`)
2. Configuration (`/etc/gitea/app.ini`)
3. Database (`/var/lib/gitea/data/gitea.db`)
4. Repositories (`/var/lib/gitea/repositories/`)
5. Systemd service (`/etc/systemd/system/gitea.service`)
6. Nginx configuration (`/etc/nginx/sites-available/git.firefrostgaming.com`)
7. SSL certificates (`/etc/letsencrypt/live/git.firefrostgaming.com/`)

**Migration Method:** Stop service → Backup → Transfer → Install → Restore → Test

---

## Issues Encountered & Resolutions

### Issue 1: Breezehost Backdoor Accounts

**Problem:** Breezehost support backdoor accounts with password authentication on inherited servers

**Root Cause:** Standard hosting provider practice - support accounts for troubleshooting

**Security Concern:** Password-protected accounts are attack vectors

**Resolution:**
```bash
# Remove backdoor accounts
userdel -r breezehost  # TX1, NC1, Panel

# Verify removal
id breezehost  # no such user

# Disable password authentication
nano /etc/ssh/sshd_config
# PasswordAuthentication no

systemctl restart sshd
```

**Lessons Learned:**
- Always audit inherited servers for support accounts
- Remove all password-based authentication
- SSH keys only (no exceptions)

---

### Issue 2: Conflicting User Accounts

**Problem:** Multiple servers had duplicate or old user accounts (michael, architect)

**Root Cause:** Server inheritance from previous setups

**Resolution:**
```bash
# Identify all human users
cat /etc/passwd | grep -v nologin | grep -v false

# Remove duplicates/old accounts
userdel -r michael    # NC1
userdel -r architect  # Panel

# Retain intentional non-root users
# Ghost: kept 'architect' user (security best practice)
```

**Lessons Learned:**
- Document which user accounts are intentional
- Remove all legacy accounts during security audit
- One admin account per server (root or designated user)

---

### Issue 3: SSH Configuration Backup Files

**Problem:** After SSH hardening, each server has `/etc/ssh/sshd_config.backup` file

**Impact:** Not a security issue, but housekeeping cleanup needed

**Current State:**
- 6 servers × 1 backup file = 6 files to manage
- Files located: `/etc/ssh/sshd_config.backup`

**Pending Resolution:**
- Archive backups to central location
- Remove from individual servers
- **Deferred to future housekeeping session**

---

### Issue 4: DNS Propagation Timing

**Problem:** DNS changes can take time to propagate globally

**Strategy Used:**
- Changed DNS first (git.firefrostgaming.com → TX1 IP)
- Waited 2 minutes for propagation
- Tested from multiple locations
- Verified before decommissioning old instance

**Resolution:**
- Low TTL on Cloudflare helped (fast propagation)
- ~2 minute propagation time
- No extended downtime

**Lessons Learned:**
- Set low TTL before migrations (if possible)
- Test DNS from multiple sources
- Don't decommission old service until new one verified

---

### Issue 5: Nginx Configuration IP Changes

**Problem:** Nginx configuration had old IP addresses from Command Center

**Resolution:**
```bash
# Before enabling site
nano /etc/nginx/sites-available/git.firefrostgaming.com

# Updated all occurrences:
# listen 74.63.218.202:80; → listen 38.68.14.26:80;
# listen 74.63.218.202:443; → listen 38.68.14.26:443;

# Test before enabling
nginx -t
```

**Lessons Learned:**
- Always update IP bindings in configs during migrations
- Test Nginx config before enabling site
- Full restart (not reload) for major changes

---

## Verification & Testing Results

### Security Baseline Verification

**SSH Access (All Servers):**
```bash
# Test key-based authentication
ssh root@[SERVER-IP]
# Result: Connected via SSH key ✓

## Lessons Learned

### What Worked Exceptionally Well

**1. SSH Key Infrastructure Strategy**
- Deploying unified SSH key across all servers simplified management
- Testing before disabling passwords prevented lockouts
- MobaXterm key integration worked perfectly
- One key for all infrastructure = streamlined access

**2. Coordinated Reboot Strategy**
- Staggering reboots maintained infrastructure availability
- Game server downtime during maintenance window
- VPS reboots had minimal impact
- No unplanned outages occurred

**3. Micro-Block Command Format**
- Small command blocks (8-10 lines) worked perfectly for accessibility
- Mobile copy/paste remained smooth throughout
- Checkpoint system prevented cascading failures
- Error recovery was straightforward

**4. Data Migration Approach**
- Stop service → Backup → Transfer → Install → Restore pattern worked flawlessly
- Backup verification prevented data loss
- Keeping old backup on Command Center provided safety net
- Zero data loss achieved

**5. Documentation During Work**
- Creating migration log in real-time captured all details
- No need to reconstruct events from memory
- Lessons learned documented as they occurred

---

### Areas for Improvement

**1. Backup File Management**
- Need centralized location for configuration backups
- 6 sshd_config.backup files need consolidation
- Create backup management strategy

**2. Pre-Migration DNS Preparation**
- Could have set low TTL on DNS record earlier
- Would have sped up propagation during migration

**3. Firewall Documentation**
- Need centralized UFW rules documentation
- Each server's firewall rules should be in Git
- Create firewall audit script

**4. User Account Documentation**
- Should document which accounts are intentional (like Ghost's architect)
- Create standard for non-root user accounts
- Document purpose of each account

---

### Process Refinements for Future Work

**1. Security Audits**
- Create security audit checklist
- Document before/after state
- Verify all changes in staging first

**2. Service Migrations**
- Always test DNS resolution before decommissioning
- Keep old service running until new one fully verified
- Document all configuration changes
- Create rollback procedure

**3. System Updates**
- Coordinate update schedule
- Batch updates to minimize reboot frequency
- Test updates on non-critical systems first
- Always backup before major updates

**4. Git Workflow**
- Commit configurations immediately after changes
- Don't wait until end of session
- Use descriptive commit messages
- Tag major milestones
