Installation of the Odin Automation interrupts with the following warning:
"Warning! The firewall cannot be configured, because the conntrack module either is absent from the Linux kernel or its use is not allowed. If you want the firewall to be configured automatically, abort the installation and fix the issue with conntrack (vizit https://kb.cloudblue.com/en/128487 for details), before launching the installation again. Otherwise, proceed with the installation and configure the firewall later.
Do you want to continue the installation? [y/N]:"
As the conntrack module is used by Odin Automatin firewall, it must be present in the Linux kernel and should be enabled. The most common reason for this issue, is that the Odin Automation management node is being deployed inside a Virtuozzo container, where the conntrack module is disabled by default.
Abort the installation of Odin Automation. Open console on the harware node and shut down the container allotted for the Odin Automation managemnet node, using the following command:
#vzctl stop %container_ID%
Enable conntrack by running the command below:
#vzctl set %container_ID% --netfilter stateful --save
Start the container:
#vzctl start %container_ID%
After that, enter to the container and run the Odin Automation installer.
