Dafu Lottery Linux Version System Iteration Update Log
Report Date: 2026-09-06 | Reporter: dajian168 Technical Operations Team
I. Version Deployment (2026-09-05)
v1.0 Production Environment Setup
Completed deployment of three sets of services: main site (member end), admin backend, and data collection source station; configured independent domains and SSL certificates
Launched 12 proprietary lottery types (SSC series, K3 series, Happy Lottery, 11选5, 3D, PK10, Mark Six, etc.); drawing, settlement, and cron task guard processes are all ready
Database schema compliance remediation: fixed 8 IP field length defects, eliminating silent write failures in login/registration/audit data
Primary-backup strategy: dual-process monitoring for collection and drawing tasks, with abnormal processes auto-restarted
II. Bug Fixes & Optimization (2026-09-05 ~ 09-06)
K3 Ods Repair: Payout calculations and bet slip reconciliation are now consistent; live testing confirms the bet→win→payout closed loop works correctly
Member Withdrawal Pipeline Repair: Full flow from withdrawal request → captcha verification → review → disbursement is now functional; fixed withdrawal failures caused by template syntax errors and missing database fields
UI Localization: Removed redundant multilingual switcher; interface unified to Simplified Chinese
Full Lottery Type Audit: Completed 22 real member-end workflow tests (registration/login/purchasing/bet slips/history/cancellation, etc.); identified and documented 2 issues pending optimization
III. Security Hardening (2026-09-06, all implemented and verified)
Login Defense
Measure | Description
Image CAPTCHA | Admin login requires CAPTCHA to prevent brute-force scripts
Lockout on Failure | Account locked for 1 hour after 3 consecutive failed attempts; verified effective in live testing
IP Whitelist/Blacklist | First successful login IP auto-registered; blacklisted IPs are directly denied access to the admin backend
Anomalous Login Alert | Unusual IP login triggers real-time Telegram alert (including account/IP/geo/time)
Audit Anti-Tampering
Measure | Description
Operation Audit | All critical config changes in the admin panel are logged (operator/IP/time/before-after values)
Secondary Confirmation for Sensitive Operations | Modifications to customer service/payment configurations require admin password re-verification
CSRF Protection | Form token validation prevents cross-site forged submissions
Change Monitor Sentinel | System config and key files auto-compared every 5 minutes; tampering triggers instant alert; simulated attack captured in testing
Admin Backend Management Enhancements
IP Whitelist/Blacklist Management Page: Unified view of whitelist/blacklist and error records; supports one-click whitelist/blacklist/remove/manual add; all operations logged to audit trail (super admin only)
Admin Log Entry: Admin panel visual entry restored; all audit records searchable by user/IP/time
IV. Current Security Baseline
Single admin entry point with triple verification: account password + security code + CAPTCHA
Whitelist IPs: 3 (1 management + 2 server egress)
3 failed attempts auto-register IP; one-click ban available
Config change monitoring with 5-minute alert granularity
