Hi,

I have enabled owner match support in kernel version 2.6.35.5 through,

Networking -- Networking options -- Network packet filtering framework (Netfilter) -- Core netfilter configuration -- "owner" match support

I have compiled the kernel and rebooted, but csf is showing this error,

************
iptables: Unknown error 4294967295
Error: iptables command [/sbin/iptables -I OUTPUT -p tcp --dport 25 -m owner --uid-owner 0 -j ACCEPT] failed, at line 338
************

I have found out that the ipt_owner module is not enabled in the kernel. can you help me enabling this module in the kernel?

Iptables should have its own "libipt_owner.so" and the kernel should have "/lib/modules/2.6.35.5*/kernel/net/ipv4/netfilter/ipt_owner.ko": please check. If the kernel was installed properly then running 'modprobe ipt_owner' should load the module and its dependencies (check by running 'lsmod') before applying your iptables rule set.

//NTLB

~]# find /lib/modules/2.6.35.7/kernel/ -name *owner* -type f
/lib/modules/2.6.35.7/kernel/net/netfilter/xt_owner.ko

This is my lsmod output and that of find command, can you please advice.

ipt_owner is xt_owner in newer kernels so that's OK. Searching for "iptables: Unknown error 4294967295" yields a lot of information but I can't anything that relates to your posted rule (if that actually is line number 338), sorry.

am guessing that ipt_owner is xt_owner in new kernel versions and xt_ replaces ipt_.....
is that rite? please help!
