Introduction<\/p>\n\n\n\n

cPHulk Brute Force Protection is a built-in security feature in WHM\/cPanel designed to protect servers from brute-force login attempts on services like WHM, SSH, cPanel, FTP, and Email. Sometimes, however, you may get locked out of WHM or SSH because cPHulk has blacklisted your IP. Clearing or flushing the cPHulk cache helps reset the failed login history and remove incorrect bans.<\/p>\n\n\n\n

Prerequisites<\/p>\n\n\n\n

Before clearing the cache, make sure you have either root access to WHM or an SSH user with sudo privileges<\/p>\n\n\n\n

Implementation<\/p>\n\n\n\n

Method 1: Clear cPHulk Cache via WHM Interface<\/p>\n\n\n\n

    \n
  1. Log in to WHM as root<\/code>.<\/li>\n\n\n\n
  2. Navigate to:<\/li>\n\n\n\n
  3. Security Center \u2192 cPHulk Brute Force Protection<\/li>\n\n\n\n
  4. Click the History Reports tab.<\/li>\n\n\n\n
  5. At the top right, click \u201cFlush DB\u201d or \u201cRemove blocks and clear reports\u201d.<\/li>\n\n\n\n
  6. Confirm the action.<\/li>\n<\/ol>\n\n\n\n
    \"\"<\/figure>\n\n\n\n

    All existing failed login records and blocked IPs are cleared<\/p>\n\n\n\n

    Method 2: Clear cPHulk Cache via SSH (Root Access)<\/p>\n\n\n\n

      \n
    1. SSH into your server as root
      ssh root@your-server-ip<\/li>\n\n\n\n
    2. Flush the cPHulk login history
      \/usr\/local\/cpanel\/bin\/cphulk_pam_ctl –flush<\/li>\n\n\n\n
    3. Restart the cPHulk service
      \/scripts\/restartsrv_cphulkd<\/li>\n<\/ol>\n\n\n\n

      All failed login attempts and bans are removed immediately.<\/p>\n\n\n\n

      Conclusion<\/p>\n\n\n\n

      Clearing the cPHulk cache in WHM is a crucial recovery step when you’re locked out or need to reset failed login attempts. Always re-enable cPHulk after maintenance and whitelist your trusted IPs to avoid future issues<\/p>\n","protected":false},"excerpt":{"rendered":"
