Setting up FreeBSD and jails on Azure – part 1: networking

This tutorial by user Gianugo shows us how to set up FreeBSD jails on the Microsoft Azure platform.

Original post:

azureI set up this blog on Azure as an excuse to play with the new FreeBSD VM Depot image, learn more about jails and write the occasional blog post about random stuff. I took extensive notes while at it and I will be posting them here for future reference and to help the occasional search engine user.

I will skip all the clicking through that can easily get to a running FreeBSD VM in Azure. There is tons of FreeBSD documentation, including specific Azure tutorials that my team and others have written. I am lazy, so I will just point out specific Azure differences and how to take care of them.

A word of caution: please don’t consider what you read here to be authoritative. I’m doing this for fun and my free time is what it is, so don’t think I researched this stuff thoroughly. It worked for me and seems to be still working as I write this – that’s all I needed.

Let’s start with networking. Every public cloud has their own approach, and Azure is no different. Two things to remember about Azure IP management:

[FreeBSD] How to allow Root access on FreeBSD over ssh protocol

This article by InfySim shows us how to set up Root access through SSH protocol on FreeBSD.

By default FreeBSD does not allow root access over ssh protocol.
So if you need to log on to your system and need root privilege, then you have to allow root to access for ssh login.
In this example I am using VIM as the text editor but if you don’t have VIM editor then you have to use the default EE or VI editor.

If you want to install VIM editor please have a look at the following link:
Installing VIM editor on FreeBSD


To do so, You will need to edit the SSH daemon configuration file.

#vim /etc/ssh/sshd_config

Find the below line in the above file:

#PermitRootLogin no

The preceding # mark shows that this line is commented.
You just have to un-comment the line and modify the “no” at the end of file to “yes” (Of course without the quotes).
After modification the line should be looking like as following:

PermitRootLogin yes

Save the file and quit vim editor.

Now to reflect the change, you have to restart the ssh daemon by typing the following command on the console:

# /etc/rc.d/sshd restart

After the above steps if you try accessing your system from another host over ssh protocol, you must be able to login to your system.


If you need to know more on VIM commands then please have a look at the following link:

15th Anniversary and Spring Fundraising Kickoff

The FreeBSD Foundation is celebrating 15 years of supporting the FreeBSD Project. Congratulations!! In this blog they discuss their Spring fundraising initiatives. Make a donation today and help keep FreeBSD alive.

Original post:

FreeBSD Foundation

I’m so excited to announce our spring fundraising campaign. I know it’s not officially spring yet, but it sure feels like it here at Foundation headquarters in Boulder, Colorado. We’re kicking off our fundraising campaign in conjunction with some other exciting events. There’s so much to celebrate. First, we are proud to be a Platinum sponsor of AsiaBSDCon. This is the tenth AsiaBSDCon, with over 140 attendees planned, and 31 talks, providing a venue for all things BSD in Asia. People from around the world attend this conference to learn about the BSD operating systems, share their knowledge and experience, and work together to develop, hack, fix, improve, and document the various BSD operating systems.

FreeBSD Now Supports DisplayLink Adapters

According to, USB-based DisplayLink graphics adapters are now supported in FreeBSD, thanks to the developers.

displaylinkThe FreeBSD kernel finally has support for USB-based DisplayLink graphics adapters.

Within the Linux world there’s been DisplayLink work going back to 2009 with frame-buffer and X.Org drivers and by 2012 had advanced to having a DisplayLink DRM/KMS driver. DisplayLink USB 2.0 devices continue to work quite well under Linux and these USB display chips can be found in a wide variety of products.

As of last week, the FreeBSD kernel has USB DisplayLink support in the form of a frame-buffer (FB) and virtual terminal (VT) drivers. The initial FreeBSD DisplayLink support was pushed via this SVN commit.

For those looking for Linux (and assuming BSD too) friendly DisplayLink hardware, I’d recommend checking out the Plugable selection with having used some of them myself. You can find the Plugable USB display product selection at

Installing a Unix-like Desktop Operating System ‘PC-BSD 10.1.1′

This tutorial by user Babin Lonston shows us how to install the latest PC-BSD 10.1.1.

Original post:

pcbsd-logoPC-BSD is a open source Unix-like desktop operating system created upon the most recent release version of FreeBSD. PC-BSD purpose is to make the experience of FreeBSD easy and obtainable for the regular computer user by providing KDE, XFCE, LXDE and Mate as the graphical user interface. By default PC-BSD comes with KDE Plasma as its default desktop environment, but you can have the option to select your choice of desktop environment during installation.

PS-BSD comes with per-built support for Wine (running Windows software’s), nVidia and Inter drivers for hardware acceleration and also an optional 3D desktop interface via Kwin (KDE X Window Manager) and also it has it own package management model that enables users to install software packages offline or online from PC-BSD repository, which is different and unique for BSD operating systems.

Recently, PC-BSD project has announced the availability of PC-BSD 10.1.1. This new release comes with number of new improved features, better GPT support and number of desktop utilities have been ported to Qt 5.

This article describes the basic instructions on installing PC-BSD 10.1.1 using the graphical installer using DVD / USB method.

How to share ElasticSearch mappings in files on FreeBSD

ImageThis tutorial by shows us how to get ElasticSearch mappings shared with files in FreeBSD.

Original post:

Using the API

You could specify the index mappings using the PUT mapping API, but you’d have to do that every time:

Create the index with the mapping:

    "mappings" : {
        "awesome_doctype" : {
            "properties" : {
              "a_mysql_date" : {
                "type" : "date",
                "format" : "yyyy-MM-dd HH:mm:ss"
              "a_string" : {
                "type" : "string",
                "analyzer" : "french"
              "a_long" : {
                "type" : "long"
              "a_boolean" : {
                "type" : "boolean"

FreeBSD Flame Graphs

Brendan Gregg, a senior performance architect at Netflix, gives a talk about various FreeBSD flame graphs.

At the last FreeBSD Developer and Vendor Summit, I gave a talk on “Flame Graphs for FreeBSD”, where I summarized the different types (CPU, memory, disk I/O, off-CPU, chain graphs), showed how they can be generated on FreeBSD, and did some live demos. I think it’s one of my best talks so far, whether you care about FreeBSD or not, to see how this visualization can be used to navigate different types of profiling data.

The slides are on slideshare:
