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5 unauthorized/outdated user accounts across inherited servers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:

TX1 Dallas - Password auth enabled, unauthorized users present
NC1 Charlotte - Password auth enabled, unauthorized users present
Panel - Password auth enabled, 118 pending updates
Command Center - Clean (deployed post-security model)
Billing - Clean (deployed post-security model)
Ghost - Clean but pending restart

Audit Method:

# 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):

# 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:

# 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:

TX1 Dallas: breezehost ✓
NC1 Charlotte: breezehost, michael ✓
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:

# 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:

Ghost CMS (non-critical, standalone)
Billing (low traffic, monitoring in place)
TX1 Dallas (game servers - coordinated downtime)
NC1 Charlotte (game servers - coordinated downtime)
Panel (control plane - brief downtime acceptable)
Command Center (management - last to reboot)

Reboot Process (Per Server):

# 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:

# 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:

Gitea binary (/usr/local/bin/gitea)
Configuration (/etc/gitea/app.ini)
Database (/var/lib/gitea/data/gitea.db)
Repositories (/var/lib/gitea/repositories/)
Systemd service (/etc/systemd/system/gitea.service)
Nginx configuration (/etc/nginx/sites-available/git.firefrostgaming.com)
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:

# 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:

# 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:

# 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

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

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

Next Steps

Immediate (Next Session)

1. Remaining Housekeeping

Consolidate 6 sshd_config.backup files
Archive to Git repository
Clean up from individual servers
Priority: Low (not urgent)
