Comunità Debian @ducc-it 2017

Aaaaand back from where I've met many members of the Debian and Ubunty communities in Italy, and had a chance to talk about the Debian Community (represented in the slide below :) )

Yes, there was a hat...

(and there will be a longer post soon-ish. when it's ready.)

@Gruppo Linux Como


Back to the roots: FidoNet |

Back in the good old days there was no Facebook, Google+, Skype and no XMPP servers for people to communicate with each other. The first "social communities" were Bulletin Board Systems (BBS), if you want to see those as social communities.
@Gruppo Linux Como can we run a BBS node for the LUG? can we? can we? :D


Edizione 2017 - DUCC-IT

Kontalk 4.0.0 - final group chat release

After a very long time... Compared to beta6.1, there are just a few bug fixes. For those coming from 3.1.10, here is a quick list of changes: group chats toggle encryption per chat internal logging system sticky conversations new app icon by Giovanni Lauricella organize preferences by category more reliable registration procedure Group chats work fine, but as a community project we always need your feedback for both bugs and improvements. Don't hesitate to open bugs at GitHub or discus...

Bradley M. Kuhn on paragraph 2 questions






From the answer to the last question on

# this_was_too_epic_not_to_do_this
# what_do_you_mean_this_is_not_tumblr?
# of_course_it's_not,_this_is_federated!
# also_my_screncapping_skills_are_not_tumblr_grade

And, for a person I know who complains about screencaps, this is the transcript:

but remember the GPL was designed to defend your freedom
and the conversation you're actually having is
how much freedom can we take away, please tell us!
and we say "you are not allowed to take away any freedom"
but can we take away a little bit of freedom?
well you have to ask a lawyer
why should we have to ask a lawyer how much freedom we can take away?
you should tell us how much we can oppress you
don't fall in that trap

Friendica problem?


cari esperti di friendica, ho cambiato il mio avatar, nel mio profilo, vedo il mio nuovo avatar, ma quando posto, i post hanno il vecchio avatar. Dove sbaglio? (O dove sbaglia friendica?)

Modern XMPP Server

I've published a new HOWTO on my website:

Enrico already wrote about the Why (and the What, Who and When), so I'll just quote his conclusion and move on to the How.

I now have an XMPP setup which has all the features of the recent fancy chat systems, and on top of that it runs, client and server, on Free Software, which can be audited, it is federated and I can self-host my own server in my own VPS if I want to, with packages supported in Debian.


I've decided to install prosody, mostly because it was recommended by the RTC QuickStart Guide; I've heard that similar results can be reached with ejabberd and other servers.

I'm also targeting Debian stable (+ backports); as I write this is jessie; if there are significant differences I will update this article when I will upgrade my server to stretch. Right now, this means that I'm using prosody 0.9 (and that's probably also the version that will be available in stretch).

Installation and prerequisites

You will need to enable the backports repository and then install the packages prosody and prosody-modules.

You also need to setup some TLS certificates (I used Let's Encrypt); and make them readable by the prosody user; you can see Chapter 12 of the RTC QuickStart Guide for more details.

On your firewall, you'll need to open the following TCP ports:

  • 5222 (client2server)

  • 5269 (server2server)

  • 5280 (default http port for prosody)

  • 5281 (default https port for prosody)

The latter two are needed to enable some services provided via http(s), including rich media transfers.

With just a handful of users, I didn't bother to configure LDAP or anything else, but just created users manually via:

prosodyctl adduser

In-band registration is disabled by default (and I've left it that way, to prevent my server from being used to send spim).

prosody configuration

You can then start configuring prosody by editing /etc/prosody/prosody.cfg.lua and changing a few values from the distribution defaults.

First of all, enforce the use of encryption and certificate checking both for client2server and server2server communications with:

c2s_require_encryption = true
s2s_secure_auth = true

and then, sadly, add to the whitelist any server that you want to talk to and doesn't support the above:

s2s_insecure_domains = { "" }


For each virtualhost you want to configure, create a file /etc/prosody/conf.avail/ with contents like the following:

VirtualHost ""
enabled = true
ssl = {
key = "/etc/ssl/private/";
certificate = "/etc/ssl/public/";

For the domains where you also want to enable MUCs, add the follwing lines:

Component "" "muc"
restrict_room_creation = "local"

the "local" configures prosody so that only local users are allowed to create new rooms (but then everybody can join them, if the room administrator allows it): this may help reduce unwanted usages of your server by random people.

You can also add the following line to enable rich media transfers via http uploads (XEP-0363):

Component "" "http_upload"

The defaults are pretty sane, but see for details on what knobs you can configure for this module

Don't forget to enable the virtualhost by linking the file inside /etc/prosody/conf.d/.

additional modules

Most of the other interesting XEPs are enabled by loading additional modules inside /etc/prosody/prosody.cfg.lua (under modules_enabled); to enable mod_something just add a line like:


Most of these come from the prosody-modules package (and thus from ) and some may require changing when prosody 0.10 will be available; when this is the case it is mentioned below.

  • mod_carbons (XEP-0280)
    To keep conversations syncronized while using multiple devices at the same time.

    This will be included by default in prosody 0.10.

  • mod_privacy + mod_blocking (XEP-0191)
    To allow user-controlled blocking of users, including as an anti-spim measure.

    In prosody 0.10 these two modules will be replaced by mod_privacy.

  • mod_smacks (XEP-0198)
    Allow clients to resume a disconnected session before a customizable timeout and prevent message loss.

  • mod_mam (XEP-0313)
    Archive messages on the server for a limited period of time (default 1 week) and allow clients to retrieve them; this is required to syncronize message history between multiple clients.

    With prosody 0.9 only an in-memory storage backend is available, which may make this module problematic on servers with many users. prosody 0.10 will fix this by adding support for an SQL backed storage with archiving capabilities.

  • mod_throttle_presence + mod_filter_chatstates (XEP-0352)
    Filter out presence updates and chat states when the client announces (via Client State Indication) that the user isn't looking. This is useful to reduce power and bandwidth usage for "useless" traffic.

I had some problems with the configuration. Hope to save others from long debugging time by adding them here as comment ;-)

Initially I had put the mentioned modules at the end of the modules_enabled block of the Prosody config file.. For some reason they never made it to become active and conversation never marked their XEP as available. My final solution was to move them atop the mention of the posix module, now they are all active.

@Tobias this is funny: I have them at the bottom between -- BEGIN ANSIBLE MANAGED MODLIST BLOCK (and the corresponding END) and they work, at least under jessie. I've just upgraded the server to stretch and haven't checked yet that they are all still working.

Maybe there was something else that was commenting them out? I have no idea if there is a block comment syntax in lua.

Anyway, great idea adding the comment here, in case it is useful to somebody else.


$89 Pinebook Linux Laptop To Go On Sale Next Month - OMG! Ubuntu!

Have you been patiently waiting for further information on that cheap and cheerful (if not hugely powerful) $89 Linux ARM laptop we mentioned last year?

At the time of our article we shared the specifications of the notebooks, their price, and their potential performace.

But that aside we didn’t know anything else, like when the device might actually go on sale.

Well, now we do.
