  • Configuring a Highly Available Service on FreeBSD – part 2: CARP and devd

    In the first part of this series, we learned how to make high availability (HA) storage on FreeBSD using HAST. We learned how to control HAST and how to recover from failures. However, all those actions were still manual actions. In this second part of the series, Jeroen will teach how two basic building blocks, CARP and devd, work and how we can use them in the final part of our series to automate the failover of our NFS server.

  • GhostBSD: A User-friendly, Lightweight BSD Alternative

    GhostBSD is an open source desktop operating system based on FreeBSD which aims for a secure, user-friendly experience out of the box. GhostBSD comes with most common software choices already configured, giving the user a solid BSD installation out of the box. Adrian will tell you why he chose FreeBSD OS.


  • How Secure Can Secure Shell (SSH) Be?

    To begin, let’s concentrate on the One Time Password (OTP). We are going to achieve our already secure SSH in conjunction with OTP for remote system connections.
