Here’s a quick follow up to my previous post about my first steps with a BigBlueButton server installation. Like Jitisi, getting a basic BBB instance up and running in a VM is straight forward. There is a good description over here with lots of details that you should definitely read before giving it a go. Before you do, here’s a super abbreviation of it with some additional tips and tricks thrown in for good measure:
Now Let’s Have A Go At BigBlueButton
While virtually at DIVOC and presenting how to install a Jitsi server, I also joined other sessions. Some of them where hosted with Big Blue Button (BBB), another open source video conferencing service. I heard from others that when it comes to ‘larger’ groups, say more than 20 people, it might perform better than Jitsi. So I decided to have a look at this system as well and install it on a server.
Freifunk München Builds A Public Jitsi Server Cluster
On Tuesday this week, awlnx and Krombel of Freifunk München (FFMUC) gave a virtual presentation online about their public Jitsi Server cluster installation and how they have set up the system. Currently, it serves well over 400 simultaneous participants in the evenings in 70 concurrent rooms. And with their 20 video bridge servers they say that they are prepared for over a thousand simultaneous users!

Twitch.tv for Streaming to More Than 20 People
So there we go, I trained my virtual live demo how to install Jitsi-Meet on a server for ‘Hidden Service’ several times to make sure the session wouldn’t blow up in my face. I felt well prepared, I felt confident and I expected a handful of people to show up at best. So I set-up the session on my Jitsi Meet server and increased my server capacity to 8 cores and 32 GB RAM just to be on the save side. And then…, 270 people showed up. OMG!

Installing a Jitsi Server – Apt vs. Docker
Before I installed my first Jitsi server I thought that it must be quite a complicated affair. I searched around a bit and found a simple way to install it via a docker-compose script. The Docker script sets up a couple of Docker containers that encapsulate the different programs required to run the Jitsi-meet server such as the web server, the xmpp server and other stuff. Neat. However, there were two problems that prompted me to search for another solution in a hurry.
Are New SIM Cards Required for 5G SA?
When LTE was launched a decade ago a clear cut was made from GSM security when it came to SIM cards and authentication. As far as I remember, LTE was the first system in which mutual authentication between network and devices became mandatory. Fortunately, by the time LTE came around the corner, most subscribers already had a UMTS capable SIM cards that supported this so there was only little pain. So how about 5G?
The Data Rate of a Jitsi Voice Call
Over the past couple of weeks I’ve been using my own Jitsi instance for many voice and video calls between family and friends. It’s easy to install and use on mobile devices, which is of prime importance when asking others to communicate with you in a different way than how they are used to. One thing that made me raise my eyebrows a bit, however, was the data rate of a simple one to one voice call.
I’ll Do A Live Jitsi Meet Install Session at ‘Hidden Service’ – The First DiVOC Event!
Easter is coming and most of us will be staying at home this year. Sadly, that also means that Easterhegg, a ‘small’ German hacker event organized by the Chaos Computer Club Hamburg, has been canceled. But far from giving up, the organizers have decided to experiment how such an event could potentially be organized in cyber space.
So Easterhegg 2020 has become Hidden Service (hiding Easter eggs I suppose…), a DiVOC event, which stands for ‘Digital Verteiltes Online Chaos’. The official translation is ‘Digitally Distributed Online Chaos’ but maybe they should have translated it to ‘Distributed Virtual Online Chaos’ to match with the abbreviation. In any case, read it backwards, add a 19…
5G Standalone Architecture – RRC Inactive State
The show must go on, so at some point, network operators will start putting 5G core networks in place which means that mobile devices will use the 5G NR Standalone (SA) air interface for signaling instead of LTE anchor cells. So I had a look at 3GPP TS 38.331 which contains the Radio Resource Control (RRC) specification to see how RRC is done in 5G.

Jitsi Meet and the Number of Video Participants
In the previous blog entry, I’ve been looking at a number of different commercial video conferencing solutions and if they offer native Linux support. There are a couple of fabulous products with good Linux support out there that easily support sessions with 15-20 simultaneous video participants. Unfortunately, from a privacy and confidentiality point of view, most of them don’t fare very well at all.
As confidentiality and privacy are very important to me, a potential solution for me and others is Jitsi, which is open source from client to server and can be installed on private infrastructure. The big question for me was however: How many video participants can the clients and the server handle in a single conference? A search on the web didn’t really result in a good answer. So I set out to find out for myself.
