• Secure and track every change to your Matomo installation with the Activity Log plugin

  14 novembre 2017, par InnoCraft — Plugins

  Are you wondering how your colleagues are using Matomo (Piwik) ? Would you like to know if an unauthorized user got an access to your installation ? Would you like to remember the last actions you performed in Matomo some weeks ago ? At InnoCraft, we developed a plugin called “Activity Log”. With this feature you can easily track and check all major changes to your Matomo websites, for example : user permissions, goals, and funnels. In this article we will show you the different ways you can use it and explain why it is an invaluable plugin.

  Activity log for better security

  The activity log feature has been designed for security. Also referred to as “audit logging” or “audit trail”, with this plugin you will be able to :

  1. detect any suspicious actions
  2. detect hacker attacks
  3. help identify performance problems
  4. see clearly who did what, and when
  5. find out how people are using Matomo (Piwik) within your company

  1 – detect any suspicious actions

  With audit trail you can easily identify if a former employee still has access to your Matomo (Piwik) installation. You will then be able to know when he accessed it for the last time, and what changes she or he performed. If you got hacked, you will be able to find out if the user created, changed, or deleted any website, goals, or did anything else suspicious.

  2 – detect hacker attacks

  When an unregistered user is trying to access your Matomo (Piwik), each failed login attempt is registered within the Activity Log report.

  3 – help identify performance problems

  Activity Log can help you identify performance problems by registering the sequence of each major action a user performed. For example, if a user updated or installed a third party plugin, and suddenly Matomo (Piwik) is getting performance problems, then it is likely that the plugin update caused it.

  4 – see clearly who did what, and when

  It is always challenging in an organization to know who did what and when. With Activity Log, you will know who were the employee(s) that accessed Matomo (Piwik), created, updated, or deleted a goal, a funnel, a scheduled report, and much more.

  5- find out how people are using Matomo within your company

  By having a look at how people are using Matomo (Piwik) you will have an overview of how your colleagues use Matomo. For example, you can see who is creating Custom segments to analyse the audience in more details, who is creating funnels to learn where your users drop off. You will then be able to identify who has the knowledge and who needs training.

  Did you know ?

  You can help the Matomo (Piwik) core team make Matomo even better by sharing anonymously how you use Matomo on a day to day basis. You just need to install the following plugin : http://plugins.matomo.org/AnonymousPiwikUsageMeasurement

  What’s in it ?

  Once downloaded and installed from the marketplace, you will be able to access the activity log from the admin panel within the diagnostic section :

  

  If you are logged as a super user administrator, you will get an overview and a detailed report about who accessed Matomo (Piwik) and which actions they performed.

  Those reports are critical as they allow the super user to :

  • ensure users are following all documented procedures within your organization such as naming conventions for reports, using the right settings when adding measurables…
  • identify suspicious behavior. As those reports are gathering all major Matomo (Piwik) users activities it is easy to identify non conventional behavior.
  • replay the sequence some users went through in order to fix any potential issues.

  Activity log view report you can access through the admin panel

  So you will see in a second if an unusual user got access to Matomo (Piwik) and the different actions the user performed.
  It is also a good way to see the features that your users are using and identify potential misuse.

  As a regular user or admin, activity log is providing only the historical actions that this user performed :

  

  Actions listed in the log include any changes (add, edit, delete) to the following features (this is a non exhaustive list) :

  • Annotation
  • Custom Alert
  • Custom Dimension
  • Goal
  • Privacy settings
  • Scheduled report
  • Segment
  • User
  • Website
  • …

  This is a ideal to remember the actions they previously performed some weeks/months ago.

  Where can I start from here ?

  Activity log is a premium feature you can acquire through the Matomo (Piwik) marketplace. If you want to experience it before purchasing it, you can try it for free on our cloud infrastructure.

• What kind of streaming protocol is the following technique of FFMPEG and HTML Video tag ?

  29 avril 2022, par O Connor

  Many people were looking for live streaming solution on a web page. I want to share the following knowledge after doing so many researches and having spent so many time.

  


  Run the following command line.

  


  ffmpeg -y -rtsp_transport udp -i "my_rtsp_url" -vcodec libx264 -listen 1 -movflags isml+frag_keyframe -f mp4 http://ip_address:port_nr/test.mp4


  


  Add the following HTML video tag to your web page.

  


  <video controls="controls" autoplay="autoplay">&#xA;    <source src="http://ip_address:port_nr/test.mp4" type="video/mp4">&#xA;</source></video>&#xA;

  


  Now you can start live-streaming on your web page.

  


  My question :

  


  In general for a video playback, the browser loads the whole video file test.mp4 first and then just starts playing the video.

  


  With the above technique, how can FFMPEG keep pushing video frames to the video source of the HTML without having a complete video file first ?

  


  Or

  


  Video source of the HTML keeps pulling frames from the FFMPEG server ?

  


  Does anyone know how it works ? I am not looking for a streaming solution. I want to understand how these two work together ?

  


• Tele-Arena Lives On

  25 février 2011, par Multimedia Mike — Game Hacking

  Readers know I have a peculiar interest in taking apart video games and that I would rather study a game’s inner workings than actually play it. I take an interest on others’ efforts in this same area. It’s still in my backlog to take a closer look at Clone2727’s body of work. But I wanted to highlight my friend’s work on re-implementing a game called Tele-Arena.

  
  
  

  Back In The Day
  As some of you are likely aware, there was a dark age of online communication that predated the era of widespread internet access. This was known as "The BBS Age". People dialed into these BBSes using modems that operated at abysmal transfer speeds and would communicate with other users, upload and download files, and play an occasional game.

  BBS software evolved and perhaps the ultimate (and final) evolution was Galacticomm’s MajorBBS (MBBS). There were assorted games that plugged into the MBBS, all rendered in glorious color ANSI graphics. One of the most famous of these games was Tele-Arena (TA). TA was a multiplayer fantasy-themed text adventure game. Perhaps you could think of it as World of Warcraft, only rendered as interactive fiction instead of a rich 3D landscape. (Disclaimer : I might not be qualified to make that comparison since I have never experienced WoW firsthand, though I did play TA on and off about 17 years ago).

  TA was often compared to multi-user dungeons — or MUDs — that were played by telneting into internet servers hosting games. Such comparisons were usually unfavorable as people who had experience with both TA and MUDs were sniffy elitists with internet access who thought they were sooooo much better than those filthy, BBS-dialing serfs.

  Sorry, didn’t mean to open old wounds.

  Modern Retelling of A Classic Tale
  Anyway, my friend Ron Kinney is perhaps the world’s biggest fan of TA. So much so that he has re-implemented the engine in Java under the project name Ether. He’s in a similar situation as the ScummVM project in that, while the independent, open source engine is fair game for redistribution, it would be questionable to redistribute the original data files. That’s why he created an AreaBuilder application that generates independent game data files.

  Ironically, you can also telnet into a server on which Ron hosts an instance of Tele-Arena (ironic in the sense that the internet/BBS conflict gets a little blurry).

  I hope that one day Ron will regale us with the strangest tales from the classic TA days. My personal favorite was "Wrath of a Sysop."
