The CSF project is abandoned, and newly installed CWP Pro already has several issues during installation.

@Sandeep B. Do you have any idea how to replace CSF in CWP Pro servers?

🔍 Issue Summary (CSF v15.00):

• csf and lfd are both properly installed and running:

  • systemctl status csf → active (exited)

  • systemctl status lfd → active (running)

  • Manual commands such as csf -e, csf -r work as expected

  • lfd.log confirms proper startup, log watching, and IP tracking

However, the CSF firewall still shows as "Disabled" on the CWP Admin interface.

✅ What Works Correctly (on another server):

• On a similar environment (CWP Pro + AlmaLinux 9.x), the CSF firewall is correctly shown as active in the CWP interface when using csf v14.24 (CentOS Web Panel)

• All functionality and UI detection works fine with that version
