Hello,

I have a wierd bug with CSF , it started 2 days ago.

first my server and cpanel info :

WHM 11.23.2 cPanel 11.23.4-R26118
CENTOS Enterprise 5.2 i686 on standard - WHM X v3.1.0

What happens is if cpanel backups starts to run is that in the middle of the process it makes the server unreachable. (not reachable so needs reboot)

No high cpu or load and mem use is ok

Didn't find any errors in logs so i disabled CSF and LFD and did a cpanel backup run.

Then the server doesn't disconnect the connection and server doesn't need reboot.

Is this a bug or a setting?

Best Regards,

If you're getting locked out, then it's possible that you have a cron job that is flushing iptables incorrectly. Check the root crontab via crontab -e, also in /etc/crontab and /etc/cron.*/ for any job or file that might relate to iptables or any other type of firewall (e.g. APF).

If it was csf blocking then there would be evidence for it in /var/log/lfd.log

chirpy,

what i did to fix it is i add a cron to disable csf before backup and after backup i start it again.

it's not a good solution but it havn't been locked out anymore now
