This forum is only for reproducible bugs with csf and lfd (i.e. not iptables problems, lack of understanding how to use a feature, etc). Posts must be accompanied with full technical details of the problem and how it can be recreated. Any posts not adhering to this, or not considered bugs, will be moved to the General Discussion (csf) forum.
Just to mention that with latest version csf v5.04, when uprading from v5.03 on a
CentOS release 4.8 (Final) 32-bit system, I got these error (?) messages :
open3: exec of /sbin/ip6tables -v -A OUTPUT -o ! lo -p udp -m state --state NEW --dport 53 -j ACCEPT failed at /etc/csf/csf.pl line 2881
