who did what with ROOT?!

When you are not sure who is using SUDO on a server, and you really need to know who keeps making that annoying change.  You can install something to watch them, and maintain that software and related logs. Keep it setup in your package management system, and make sure it doesn’t have any patches.

OR

You could use the little-known (at least those I have asked in the field) modifications I will list below.  They are two fold.  One, you will enable to record who logs in and uses SUDO, and records their session. Much like many pieces of software out there today.  The one catch to my method is simple.  You already have the software installed, yup this has been a feature of SUDO since version 1.7.4p4.  So nothing else to install, worry about, or maintain.  It is also very easy to setup, see below:


/etc/sudoers modifcation:
All you need to do is to add 2 tags to all required sudoers entries.
*(where "su" specified, either with command or alias). 
LOG_INPUT and LOG_OUTPUT
Example: 
%admins ALL=(ALL) NOPASSWD: LOG_INPUT: LOG_OUTPUT: ALL

Add the following default log dir structure to sudoers:
Defaults iolog_dir=/var/log/sudo-io/%{user}
Note:
Output is logged to the directory specified by the iolog_dir option (/var/log/sudo-io by default) using a unique session ID that is included in the normal sudo log line, prefixed with TSID=.  The iolog_file option may be used to control the format of the session ID.  Output logs may be viewed with the
sudoreplay(8) utility, which can also be used to list or search the available logs.   Keeping in mind that if the user has a really long session you will be viewing it like a movie, it will replay as if he is sitting there typing.  With this in mind, sudoreplay gives you the ability to play back at faster speeds.  This makes it easier to find where things happened in a long recording.

So that is one good method to help find a culprit, but what if you are just looking at history of root?  Can you tell me who ran what? Can you tell me when they ran the commands you see when you type ‘history’?  By default, no.  The next tidbit of info is very useful, and extremely easy to add to your machines.  Simply add the following to your /etc/profile:

export HISTTIMEFORMAT=”%d.%m.%y %T “

Yes, that is a space at the end.  If you do not put that in there you will end up with it running together with the actual command typed in history.  So your history should look like the example below:

1995 06.10.15 13:08:05 top
1996 06.10.15 13:08:05 clear
1997 06.10.15 13:08:05 df -h
1998 06.10.15 13:08:05 umount /media
1999 06.10.15 13:08:05 sudo umount /media
2000 06.10.15 13:08:05 sudo su –
2001 06.10.15 13:08:07 history

I hope this helps someone save some time, as it has me.  Please feel free to share with others.

Thank you to all… Jasper v1.6 Image News!

First, I would like to say thank you to the community members for helping out. I have gotten a lot of input on the new image.  This has also given me better feel for what the community wanted in an image. Which leads me to the next bit of news.


Some of you are undoubtedly wondering why I have not released my Jasper v1.6 image as of yet.  Well, I can assure you there are very good reasons.

Firstly,  I have had some severe family/health issues come up as of late which take priority.  I am also in the middle of moving a family of 5.  Combine that with the other reasons below, and I feel that most will feel the wait to be worth it.

This leads me to the next bit of news, however shocking it may be.

  1.  There will be no version 1.6 image.
    1. There will be no image at all…
  2.  Instead, there will be a full installer.
    1. This is one of the reasons for the delay.
  3.   The installer will work with a full GUI, and on the desktop.
    1. Examples:
      1. Full ubuntu Install.
      2. Fresh RPI install with GUI.
  4. The installer will be iterated on by feature going forward.
    1. We can add community approved features one at a time.
      1. Example:
        1. Change Jaspers Name
        2. Change STT after setup
        3. Etc.

FAQ (COMING SOON)

  • So whats that mean for me?
  • What do I do if I am running Jasper v.15?
  • Where do I get the installer?
  • Do I need to upgrade?

 

Jasper Kits on hold…

These were for the community, and I have enjoyed designing and building these kits.  However, I am at a point now, where I do not have the time to properly maintain and build and ship them.  This is not necessarily a permanent decision, I may bring them back in the future given I have the time.

That being said, I do have a few left.  If you are interested please let me know now.  I will get an exact count soon, and update it here.  Once they are gone, I will not be building more.

With all that being said, I am still here to help with questions.  I am also still developing what I hope is a better user experience with my images.  (Version 1.6 out soon!)

If you have any questions; or would like one of the last kits, I would suggest speaking up now.  Not that I will disappear, but I will be unable to spend the time on them for a while starting soon.

I also wanted to say thank you again to the community members that are helping each other, and the new guys.  I do notice, and it is appreciated.

Jasper Image V1.6 – Release Date!

I have recently had a large number of people wanting to know the exact release date for the v1.6 image. I will release it without the installer, and release the installer separately so it can be used on images that are not mine.

  • Release Date:
    February 15, 2017

I would highly suggest that if there is annoyance; or fix for the next release that it be reported ASAP to the room in our SLACK.

 

Thanks for your patience,

Matthew Curry

Jasper Image v1.6 – Coming Soon!

There are already several improvements to the image, and I have put out feelers for any fixes/updates/etc that I can do to make the user experience better.  I already have a few of the obvious ones, however please feel free to report them in the new slack room “image-v1-6”, or in the Forums at the following LINK.

I am already working on it being pre-installed in the future with a REST api on it.  Making it easy to integrate with anything!

I will be posting the release notes with the new updates with the new image, and here as a post.  So please keep an eye out.

 

Thanks,
Matt

NEW Jasper Documentation!

Hello All,

First, I want to thank everyone that has been patient with me so far in getting these things done one at a time…

I know it is not easy to get some of these things completed without good documentation.  So, with the help of a few community members, I have started what is a very rough draft of our documentation.  It is neither complete, or ready….  However, we are adding information as we go, so keep a close eye.  Even feel free to clone it, and contribute.  There will be documentation on how to do both of those coming as well.  Feel free to watch here, the repository, or the Support Forums/Slack for updates.  I update them all.

If you have items you would like to see added to the documentation, I would run it by myself, or d34dman first.  If we have not already written it (there are some not committed yet); then we will just let you know to put in a PR (aka Pull Request).  Once we have both reviewed it and give it a thumbs up.  We will merge it.

Alright, all that said… Here is the link to the documentation!

 

Thanks,

Matthew Curry

Jasper Client Links

These are several links I have compiled, and/or created in the last few months. They can help you get Jasper going. I am also working on a full how-to for both RPI2 and RPI3.

  • Jasper-Support-Forums
    • Support forums, I help run these if you have any questions. Contact Me.
  • SLACK SIGN UP
    • Chat room for helping with Jasper
  • Jasper-Client
    • Official Jasper-Client
  • Jasper-RPI-Tools:
    • Set of tools I created in helping setup Jasper/RPI. They are a work in progress, so be sure to do a ‘git pull’ often.
  • RPI-Jasper-Dependencies:
    • Set of pre-compiled dependencies, that would normally take hours to compile. Tested on RPI2/3. Usually used for a non-Jasper image; as the images I created have them all installed.

    • Help with ‘.asoundrc’, and setting your default audio device
    • Usually the most common road block.
  • Home-Assistant.io: Home automation for the RPI, works very well. Working on integration on the same RPI; however it has dependency conflicts. Testing in pyenv soon…
