Changes:

  • Fixed missing copy for the portscan.txt report for generic installations
  • Added new option PS_EMAIL_ALERT to enable/disable Port Scan Tracking email alerts

New csf v3.07

Changes:

  • Added Apache Server Status report to PT_LOAD for load average report monitoring.

The open is enabled by default. The report is generated from the exploitalert.txt template file
