From c7a409622bc9ca02df2099a79d6974e8c4608f5a Mon Sep 17 00:00:00 2001 From: cschantz Date: Thu, 25 Dec 2025 16:24:21 -0500 Subject: [PATCH] Fix IP reputation persistence - snapshots were being deleted on exit MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CRITICAL BUG FOUND: Live attack monitor was "losing track" of blocked IPs because IP reputation data was being saved to $TEMP_DIR then immediately deleted on cleanup. Line 149: rm -rf "$TEMP_DIR" deleted ALL IP tracking data Line 154: Said "snapshot saved" but was a LIE - already deleted! This caused: - No persistent IP reputation tracking across monitor restarts - Duplicate block attempts on same IPs - Lost attack history and ban counts - No permanent block logging ROOT CAUSE: save_snapshot() saved to: /tmp/live-monitor-$$/snapshot.dat cleanup() deleted: /tmp/live-monitor-$$ (entire directory) Result: All IP data lost on every exit THE FIX: 1. Snapshot Persistence (lines 161-189): save_snapshot() now saves to: ✓ $SNAPSHOT_DIR/latest_snapshot.dat (permanent storage) ✓ $SNAPSHOT_DIR/snapshot_TIMESTAMP.dat (timestamped history) ✓ Keeps last 10 snapshots, auto-cleans older ones ✓ Survives script exit/restart 2. Cleanup Function (lines 129-173): ✓ Calls save_snapshot() BEFORE deleting temp files ✓ Writes all IP_DATA to reputation database ✓ Waits for DB writes to complete ✓ Shows count of saved IPs ✓ THEN deletes temp directory 3. Real-Time IP Tracking (lines 820-839): record_blocked_ip() function: ✓ Increments ban_count in IP_DATA immediately ✓ Writes to reputation DB (background, non-blocking) ✓ Logs to permanent block_history.log file ✓ Format: timestamp|IP|reason 4. Blocking Function Integration: block_ip_temporary() (lines 921, 930, 950): ✓ Calls record_blocked_ip() after successful block block_ip_permanent() (line 1010): ✓ Calls record_blocked_ip() with "PERMANENT:" prefix PERSISTENT STORAGE LOCATIONS: /var/lib/server-toolkit/live-monitor/ ├── latest_snapshot.dat (current IP_DATA state) ├── snapshot_TIMESTAMP.dat (timestamped backups, last 10) └── block_history.log (append-only block log) BENEFITS: ✓ IP reputation persists across monitor restarts ✓ Historical tracking of all blocks with timestamps ✓ No duplicate blocking of same IPs ✓ Ban counts accumulate properly ✓ Attack patterns preserved for analysis ✓ Automatic cleanup (keeps last 10 snapshots) TESTED: ✓ Bash syntax validation passed ✓ Files synced (main + v2) --- .sysref-test | 16 ++++++ .sysref-test.timestamp | 1 + modules/security/live-attack-monitor-v2.sh | 62 ++++++++++++++++++++-- modules/security/live-attack-monitor.sh | 62 ++++++++++++++++++++-- 4 files changed, 131 insertions(+), 10 deletions(-) create mode 100644 .sysref-test create mode 100644 .sysref-test.timestamp diff --git a/.sysref-test b/.sysref-test new file mode 100644 index 0000000..9ea9fb5 --- /dev/null +++ b/.sysref-test @@ -0,0 +1,16 @@ +# Test System Reference Database +# Platform: cpanel +# Generated: Wed Dec 24 03:16:31 PM EST 2025 + +[USERS] +USER|pickledperil + +[DOMAINS] +DOMAIN|pickledperil.com|pickledperil|/home/pickledperil/public_html|/etc/apache2/logs/domlogs/pickledperil.com|ea-php81|yes|primary|www.pickledperil.com|200|200|200_OK +DOMAIN|www.pickledperil.com|pickledperil|/home/pickledperil/public_html|/etc/apache2/logs/domlogs/pickledperil.com|ea-php81|no|alias|pickledperil.com|200|200|alias_of_200_OK +DOMAIN|67-227-141-132.cprapid.com|unknown||/var/log/apache2/domlogs/67-227-141-132.cprapid.com||unknown|local||timeout|timeout|TIMEOUT +DOMAIN|cloudvpstemplate.host.pickledperil.com|unknown||/var/log/apache2/domlogs/cloudvpstemplate.host.pickledperil.com||unknown|local||200|200|200_OK + +[DATABASES] +DB|pickledperil_wp_wt6lz|pickledperil + diff --git a/.sysref-test.timestamp b/.sysref-test.timestamp new file mode 100644 index 0000000..a62939c --- /dev/null +++ b/.sysref-test.timestamp @@ -0,0 +1 @@ +1766607398 diff --git a/modules/security/live-attack-monitor-v2.sh b/modules/security/live-attack-monitor-v2.sh index cce2b53..837f9d9 100755 --- a/modules/security/live-attack-monitor-v2.sh +++ b/modules/security/live-attack-monitor-v2.sh @@ -137,6 +137,23 @@ cleanup() { # Wait a moment for background jobs sleep 1 + # SAVE SNAPSHOT BEFORE DELETING TEMP FILES!
