IPV6 Errors on CentOS install

[londoh]

Hi

I just tried csf on a new centos 7.2 box at ovh
os is updated
kernel is 3.14.32

got this errors:

Code: Select all

csf -r    
*WARNING* URLGET set to use LWP but perl module is not installed, reverting to HTTP::Tiny
Flushing chain `INPUT'
Flushing chain `FORWARD'
Flushing chain `OUTPUT'

Flushing chain `OUTPUT'
ip6tables v1.4.21: can't initialize ip6tables table `nat': Table does not exist (do you need to insmod?)
Perhaps ip6tables or your kernel needs to be upgraded.
... 
repeat x lots and lots
...
open3: pipe(GLOB(0x2e95a18), GLOB(0x2e95a30)) failed: Too many open files at /sbin/csf line 4608.

I serach the forum and see various similar posts, but no conclusive solution.

does anyone here have any idea what the problem is and how to fix it?

thanks

You are missing LWP. To install all the recommended perl packages on Centos

Code: Select all

yum install perl-libwww-perl perl-Time-HiRes perl-Crypt-SSLeay perl-LWP-Protocol-https perl-IO-Socket-SSL perl-GDGraph perl-Socket6 perl-IO-Socket-INET6

Hi Marcele

thanks very much for reply

yes it was missing, but I installed it afterwards, and still get the same error.

I havent been able to figure it out so at the moment have disabled ipv6, which isnt a good solution since I probably will want to use it later on.

I'm grateful for any other ideas.

regards

The ip6tables module error indicates that the kernel you are using is a custom one rather than the OS vendor provided one, and the provider of that kernel has not compiled in all the standard ip6tables modules that are included in the OS vendor one. You should either switch to the OS vendor kernel, or have your custom kernel provider provide one that is compatible with the OS vendor modules that are included as standard.

thanks very much for your reply.

I've contacted them for their opinion.

I searched the forums about this and found this post relating to a similar issue:
viewtopic.php?t=8831#p24964
where you said:

We'll put in a workaround in the next release of csf (due today) that will allow IPV6 support even if the nat table is missing

did that happen? sh/would it fix it?

thanks again
