Hi.

I've read all post in internet about this. But not work.

After upgrade to Ubuntu 20.04.2 LTS CSF Firewall stop working.

Paths are correct, but still fails.

Code: Select all

 *Error* The path to iptables is either not set or incorrect for IPTABLES [/usr/sbin/ip6tables] in /etc/csf/csf.conf at /usr/local/csf/lib/ConfigServer/URLGet.pm line 26.
Compilation failed in require at /usr/sbin/csf line 21.
BEGIN failed--compilation aborted at /usr/sbin/csf line 21.

Code: Select all

 cat /etc/csf/csf.conf | grep IP6
# This option uses IPTABLES_SAVE, IPTABLES_RESTORE and IP6TABLES_SAVE,
# IP6TABLES_RESTORE in two ways:
IP6TABLES = "/usr/sbin/ip6tables"
IP6TABLES_SAVE = "/usr/sbin/ip6tables-save"
IP6TABLES_RESTORE = "/usr/sbin/ip6tables-restore"

My config about IPv6

Code: Select all

 cat /etc/csf/csf.conf | grep IPV6
IPV6 = "0"
IPV6_ICMP_STRICT = "0"
IPV6_SPI = "0"
LF_NETBLOCK_IPV6 = ""

eth0 not IPV6

Code: Select all

Testing

The error is incorrect as it is referring to ip6tables instead of iptables, therefore is actually failing on the location or permissions of IPTABLES as defined in /etc/csf/csf.conf

Erro is error showed by csf.

On the other hand, the completely correct permissions, either for iptables or ip6tables

Double and triple check

Thanks.

I see the error in other machine with Centos 8.

System is a Centos 8 upgrade from Centos 7 with some problem, such iptables. Is installed but is wrong installation.

After correct issues in upgraded system work fine.

Now I try with Ubunut, but problem is possible de same. Is and ubuntu 20 upgrade from Ubuntu 26
