    LXC Unprivileged enabling docker - Security risk?

    We would like to enbable nesting and keyctl for our LXC containers. Our customers demand these features so they can install and use Docker. There are (fairly old) posts suggesting this would be a security risk and we should be careful if we really want to do it as it could be possible for an...

    We are hosting multiple LXC containers on our dedicated servers (Debian 10). We are mainly hosting game servers and we noticed an oddly annoying pattern. Our game servers get the following errors and shut down. It happens randomly and when there are most players on each servers. terminate...

    [SOLVED] Reset user password in VM

    My team and I made the huge mistake of not saving the credentials of one of our VMs. That VM got populated with customer data and in no time we came to the conclusion we had lost access to that very VM. We used Ubuntu 18.04. We know the name of the user but the password does not want to work...
