I recently faced the task of moving an Alpine Linux-based VPS onto a FreeBSD host. I decided to use a jail.

Using VMs is a traditional and efficient way to separate servers but is it really needed when creating a FreeBSD VM on a FreeBSD host?

VPNs are very useful both for management and personal use. Many people turn to commercial companies that provide them, but it is easy to install your own on a FreeBSD VPS. Be the owner of your data.

In 2010, one morning, a client called. My task was to set up a new complex server within a tight two-day window. Given the constraints, I opted for my top choice at the time for such tasks: NetBSD and Xen. To my astonishment, over 10 years later, the server was still up and running perfectly

While following/followers numbers might not be of critical importance, especially in the fediverse, understanding the dynamics behind them can be intriguing. And that’s precisely what motivated the creation of the program we’re about to discuss.

In the recently created FreeBSD VPS, the network performance of vnet-enabled jails was significantly lower compared to that of traditional jails. Upon investigation, it appears that there is an issue related to Virtio drivers.

I’ve always kept an eye both on Android and iOS devices. I’ve been using an iPhone for the last 3+ years, and, one month ago, got a Google Pixel 7. Here’s what I found out.

RouterOS 6 is running great on bhyve. Unfortunately, things change when dealing with RouterOS 7. It doesn’t boot at all. Here’s how to solve.

This is the story of a successful migration from Proxmox to FreeBSD. VMs, LXC containers and services are now running on the new server.

The Fediverse is composed by thousands of servers (instances). I’ve started to explore the different software solutions. Here’s what I’ve found out.

Sometimes your filesystem gets stuck. No operations can be done and a “reboot” will just cause an indefinite waiting time for I/O. There’s a “magical” code that triggers a specific kernel condition - and a reboot.

This time I decided to install Mastodon on a FreeBSD jail, managed by BastilleBSD. I’ll describe a simple, one jail installation, with the related rc files.

bhyve on FreeBSD is great and Alpine Linux can be a great VM for docker or lxc/lxd container deployment, especially if using ZFS for rootfs.

FreshRSS, an excellent and complete feed aggregator, is the first service we’ve been deployng and is already waiting for your registration.

FreeBSD and Caddy play very well together for static websites/reverse proxies but we often need to serve dynamic websites. Adding PHP is quite easy.

Backup is not a tool. Backup is not a software you can buy. Backup is a strategy you need to study and implement to be able to solve your specific problems.

Many Linux users are asking how we’re migrating to FreeBSD, how jails can replace lxc or (in part) Docker, and how we’re monitoring and performing backups/restores.

We started a complex, continuous and not always linear operation, that is to migrate, where possible, most of the servers from Linux to FreeBSD. Here’s why.

If you are using Proxmox, ZFS is one of the best local storage options. You can easily backup your lxc containers using Borg.

Sometimes you want (or need) to assign a public OVH failover IP address to a FreeBSD jail but there’s not much documentation on how to do it inside a jail.

Raspberry PI i4 s a great platform for FreeBSD but if u-boot detects there’s a powered hub, the boot seems to go crazy. It isn’t even able to recognize the SD partitions. The result is that the Rpi4 won’t boot and start loop.

Watchdog devices are important to be sure our servers are working. Unfortunately, watchdog daemon seem to crash if enabled on Rasbperry PI. The problem is that our Pis have a strange watchdog hardware device and needs to be petted quite often. Because of this, running the watchdog daemon without some special flags won’t work as standard FreeBSD petting time is too high. All you need to do is enable watchdog and add a flags line with some specfic options.

Alpine Linux and lxd are perfect together, especially if combined with a good file system. Let’s see how to install them on a btrfs file system.

Lxc containers are fast, small and useful. Proxmox Backup Server is quite slow with them, so here’s how to perform a fast and efficient backup using Borg.

docker-compose allows you to define a set of containers in a single file. They will be in their “namespace” and can be linked and tied together.

We can use docker both for static and dynamic websites. We have a wide choice of images - and we can even create our own.

What I’ll be describing now is another kind of setup, based on two containers, and it will help you to understand some of the features of Docker.

Docker has been a fundamental part of my setup for more than three years now. Day after day I tried to move as many services as possible to Docker and this was a very good move.

Proxmox Backup Server (PBS) has been released. It’s still in beta but is already perfectly usable. After many years, it’s now possible to perform incremental backups of the VMs and thanks to the qemu dirty bitmaps, backups are also fast.

Many people think that it is enough to ensure that the storage medium is redundant - and you are fine. WRONG!!!!!

I have already dealt with the problem of performing a correct backup. This time I will give you some insights into how I make backups and how I am able to guarantee a certain level of security.

Cephfs is great. It can be used to store and share files and can take advantage of the granularity and performance of Ceph. Big amounts of data can be stored and live snapshots can be taken so remote backups can be easily performed.

One of the interesting features of BTRFS is the dynamic snapshot generation, which grantees the possibility to have a perfect and immediate copy of a specific path.

Sometimes containers log a lot of things, and the logfile can become huge. This happens because containers aren’t supposed to run for a long time but to be created/disposed regularly. Here’s how to fix this. You have to instruct Docker, at launch, and tell how much you want the log file to grow before rotating and how many old logs you want to keep. For example, --log-opt max-size=50m --log-opt max-file=5

I’ve been using BTRFS for years and I’ve had few problems. Some of them are small and can be avoided with some smart improvements.

Sometimes servers can become unresponsive. Both physical and virtual, you may be unable to connect to them, especially when overloaded. So a watchdog can be a solution.

Hello everybody. This is the first of a series of tech posts. The idea behind this blog is to share some of the adventures I’ll be facing in the IT world.
