I just got a virtual server (I think virtuozzo) with root access. I wanted to install shorewall but when I want to start it I get the error message

# shorewall start
Processing /etc/shorewall/shorewall.conf...
ERROR: Your kernel/iptables do not include state match support. No version of Shorewall will run on this system

So now I'm wondering what can I do? The system ist ubuntu 11.10.

Don't know why this is getting down voted, seems legit! – SimonJGreen Mar 12 '12 at 21:51
@SimonJGreen the OP wants to do things which are beyond their control. – Tom O'Connor Mar 13 '12 at 8:58

I'm thinking you are on openVZ and they haven't configured the server correctly.

What do you mean by "haven't configured the server correctly"? – toom Mar 12 '12 at 22:34
In openVZ you need to configure the host to explicitly allow this like Tom suggested. – Lucas Kauffman Mar 13 '12 at 8:10

Virtuozzo is an interesting type of virtualisation. It's actually a "jail" - in the FreeBSD sense, rather than a hypervisor type Virtual Machine, like KVM. As a result, you need to tune the options of the Virtual Machine Host, to allow certain kernel functions to be passed through.

I believe that Virtuozzo is effectively OpenVZ (or similar enough) underneath, so you'll need to edit /etc/vz/vz.conf and add "ipt_state" to the IPTABLES variable, then restart the VM. (source)

Of course, you might not be able to do this, if you don't have control over the VM Host.

No, I don't have access to the VM host. – toom Mar 12 '12 at 22:34
Well, you're SOL then. – Tom O'Connor Mar 12 '12 at 22:54
