Riot app and matrix standard for instant messaging, voice & video calling
by Pirate Praveen 13 Jun '17

13 Jun '17

Riot app and matrix standard for instant messaging, voice & video calling: Free Software, standards based and decentralized replacement for services like WhatsApp, Telegram and Skype. It has one to one or group messaging with end to end encryption for better privacy. Even though WhatsApp claims they do the same, their app being proprietary, we cannot verify their claim. Riot app is Free Software and its source code is available for anyone to verify the claim. Its audited by NCC Group, a professional security research company. With end to end encryption, only the people you share can see your information, the service provider will only see encrypted data, which they can't decrypt without encryption keys. Its like you press the button and lock a car's door, anyone can lock the door, but once locked only the person with the key can open it. Brute forcing would require huge computing power making it practically not possible. We are forced to use WhatsApp even if we don't like it because our friends are on WhatsApp and we are locked to it. With matrix free standard, we can use any app, service or even run our own server. People who try to bridge it to other services or use Free Software clients gets banned by WhatsApp. Imagine this situation, if BSNL were the only mobile service provider and Jio customers could not talk to BSNL customers, would Jio be this popular? Would BSNL and other providers be forced to match Jio offers? We as customers benefited because GSM is a Free Standard and anyone can compete with better services. We can switch providers without losing our contacts. In case of WhatsApp, even if you like Telegram, and use it, you cannot talk to WhatsApp users using Telegram. So it appears who have a choice of apps, in practice that choice is meaningless. Matrix is like GSM standard. You can get a matrix account from any service provider like diasp.in, disroot.org or matrix.org like you can buy your sim card from any provider like BSNL, Airtel, Idea etc You can choose any app, your sim is not locked to a phone model. The most feature rich app is riot, which you can install from riot.im for android, iOS and ant desktop (GNU/Linux, Windows and Mac). There are command line apps like Weechat (with plugin). Pidgin also has some basic support for matrix. Anyone can create a app for matrix standard with better features. Same for the server, anyone can write a server software with better features and performance than the current synapse software. Anyone can take these software and run a matrix server and host it in any country. We have hosted diasp.in in Noida. There are servers located in countries with better privacy laws like Germany. Once you create a matrix account and install riot app, you can join #ilug-bom:matrix.org room. https://matrix.to/#/#ilug-bom:matrix.org Some matrix servers like diasp.in, disroot.org allow registering from their website. Servers like matrix.org and tchncs.de allows registering directly from riot app. You can enter your matrix server in riot app when you login.

June 2017 meeting minutes
by Raghavendra Kamath 13 Jun '17

Hi linuxers, As per our usual schedule we had a small meetup on 10th June at Don Bosco Institute of Technology. This week Rajeev gave a talk on "How to build a Fedora Workstation Live install media". This was the same method that was used to create a custom image for St. Mary's Schools linux install fest. This time there were fewer attendees due to some members opting out due to work related and personal commitments. We reached D.B.I.T around 2.45 pm, Tayyab Sir was already present and arranged a Lab for us. While Rajeev was busy setting up his laptop, which we nicknamed "Survival Kit", rest of us were having some casual discussion about the install-fest and other happenings in Linux world. Rajeev began the talk by explaining the setup required to build a custom image in fedora. He introduced us to a utility called Mock [1], which is like an evolution of chroot and is used to build live images of Fedora, Centos, Mageia, RHEL & Openstack images. There are various mock config files templates available targeting the above mentioned platforms that we can edit and customize to build our live images. One important thing to note is that the release of fedora image that you are trying to create should match the release that you are running. Rajeev also explained to us the new strategy that fedora uses to provide a faster installation and deployment. Fedora live images are nothing but compressed system images, which are then copied to the target machine, instead of installing the application on the target machine the installation and setup is run while creating the live image itself and the actual install process, which is now handled by the utility called "liveinst", is uncompressing this system image and copying it to the target file system. Inside the mock chroot, the instruction for the install process and system image creation is provided by something called kickstart files [2], which in addition to bash commands has it's own set of syntax. All the instructions such as, name of the user, file system size, repositories to add, name of the applications to include, any custom packages, and post and pre-install scripts that needs to be run is specified in this kickstart file. Based on the instruction of the kickstart file, anaconda (fedora's install utility) installs the packages for you. The livemedia-creator utility is used to combine the all these actions and create a bootable live disk image. Rajeev also showed us how he created the custom plymouth boot animation for using the schools logo. Although what we have reported here is just a quick overview of the session (and may be slightly out of order), Rajeev explained the process very nicely and in a in-depth manner. The session had various casual discussions, which included topics like firewalld, iptables, apt vs dnf for caching updates locally, a bit of emacs vs vim, Flash, DRM and W3C's inability to curtail them :) Overall it was a fun session. Also we thank for D.B.I.T for the space and providing tea and coffee for us. We hope to see everyone in next meeting, which is scheduled on 8th July. ** links [1] https://github.com/rpm-software-management/mock/wiki [2] https://github.com/rhinstaller/pykickstart/blob/master/docs/kickstart-docs.… -- Raghavendra Kamath Illustrator raghukamath.com

Self hosting Git, IM, VoIP and Screen share
by Revant Nandgaonkar 13 Jun '17

13 Jun '17

Recently I came across a project https://yunohost.org, It's a FOSS app like cpanel, uses letsencrypt certificates and is extendable by installing apps. I've setup a vps and it's working great! Our server hosts Gogs for git, Baikal for Card/CalDAV and Rainloop as webmail. It comes with many free services installed, includes MetronomeIM ( https://lightwitch.org/metronome) as xmpp server and Mail server (postfix/dovecot). LDAP service is also configured for all apps installed and a single sign on system is also available across hosted services. I was able to login to this self hosted xmpp server using Empathy, Pidgin, AstraChat (Android with VoiP), Conversations (Android) There are xmpp multi user chatrooms (groups) possible. The main practical benefit I see in using MetronomeIM and Empathy is screen sharing. We are able to do free, unlimited screen shares! Revant
