Wireless router with 4G USB modem/dongle, by ROOTer

Previously I managed to get the OpenWRT working on a wireless router. As this router also has an USB port, I tried to get an USB 4G dongle working on it. After realizing that the solution is very much dependent on router itself and on the 4G dongle, and that I simply didn’t have all the details that was needed, then I gave up on that attempt.

And then I found that there is another effort/package called ROOTer, which is actually solving the very same problem for several routers and dongles. And that my specific HW was actually supported! After following their instructions, and installing their firmware, it worked “out of the box” (all actions from the GUI, without needing to do tweaks on the command line.) The only catch up to remember is that one need to configure the Modem data (eg. APN name, authentication etc), and when changing those parameters, they don’t become active until reboot is made.

My setup:

  • Wireless router TP-link TL-WR1043ND ver.2
  • 4G dongle ZTE MF831 (so called hostless USM modem, as these modems appear as an Ethernet device when plugged into the router)


In picture below, the model name and firmware are visible.


In next picture, it shows that the interface wan1 (4G dongle on USB) is up. It is possible to configure both the WAN (the physical cable) and 4G at the same time.


The zoning options are numerous. It is even possible to create quest wifi. In the picture below it shows the out of the box setup.

Test: O365 and Azure test lab guides

Microsoft is providing 30 day trial environments for Office 365 and for Azure. These trials can be used to setup a test and development environment by following the step-by-step guides from MS. If you are intending to start using those environments, then these Test Lab Guides can be very usefull way to get familiar on what is available and how it really works.

This test environment setup can also be very usefull for persons working with security, both for competence buildup and for testing the security features and different setups. (30 days trial limit can be very tight, and it might be better first to install only the O365 environment, and extend that one for another 30 days, and only then continue with the Azure environment. ie. follow first the O365 test/dev guides, and then after 30 days repeat the test/dev guides and include Azure in the setup…)

In the beginning it is a little confusing, as the MS guides do not show the overall big picture before starting. This might be partly because the environments are being slightly changed all the time. The picture below is trying to show that in the O365-Azre test/dev environment, there are 3 different Active Directories involved.

  • Azure AD for O365
    • This AD will contain both cloud userids (O365) and CORP userids (from simulated contoso.com, from virtual AD)
    • (note, the userid that was used to subscribe the trial is not in this AD)
  • Azure AD Free
    • This AD will contain the userid that was used to subscribe the trial (newmeail2)
  • Virtual AD (IaaS)
    • to maintain the users in the CORP domain


The different portal structure between O365 and Azure can cause confusion. The picture below is trying to show the different portals used to administrate these environments. In Azure, one portal is used, but in O365 the main Admin portal is used as jump board to access other portals… (I would assume this to change in the future).


Please note that it is possible to login to Azure portal with the O365 userid. This is because Azure is providing the Azure AD function from Azure to the O365.

BTW, after trial period, it is possible to continue this test/dev environment and pay for the services without loosing the data from trial.

Office 365

In Office 365 Admin portal, all what is needed, is there. However, the implementation is done the way that different sub-menus are actually only jump boards to other portals.


For example, Security and Compliance is a separate portal.


When it comes to Roles, then the issue becomes quite complex in the beginning. In the MS approach, security related roles like Security Administrator and Security Reader do not have access to security related configuration within diffrent services, but they only have access to central alerts, classification and policies configurations. I have not yet been able to identify a suitable reader role that could have read-only access to security related configuration in Exhange, Sharepoint, Yammer etc. It seems that this would need a customized role configuration. (Note that in the azure environment, one can have a Reader role for a subscription which can see all data as read-only (“Reader”, not “Security Reader”).


The screenshot below shows how Azure portal looks like after the setup with AD Connect is ready. In order to reduce the costs, it is good practise to stop the VMs when they are not needed.


In Azure portal, the Security Center is build into the portal and is not a separate portal like in Office 365.



All in all, these test lab guides are good way to get started. And there is a lot of information sources available for different tasks and goals. However, the information is still quite scattered, and it can be a challenge to obtain the big picture of the overall security architecture, posture or available settings, best practises and features. Not to mention that certain features require additional licenses. But that is the same with any complex environment, right? That is where security persons are needed to provide some guidance 🙂

Virtual magnifiying glass

One of the handy tools to have is virtual magnifying glass. It can be a solution when one need to enlarge only a portion of the display. For example, if you want to show some video or demo on a large screen, and the application does not support making it visually bigger. Or it can be a necessary tool for people with low vision.


There also exist a portable version (with portable apps).


  • different browsers might give different results (eg. video might work with firefox but not chrome)

    Six Thinking Hats, a method to talk about ideas, problems and challenges

    Six Thinking Hats method can be useful when taking a discussion/workshop with several participants and at the same time you want to make sure that you will get some concrete results out of the session. This method nicely gives a structured approach on how to run the session, instead of letting participants to go from one extreme into another.

    To get a quick introduction, I highly recommend to see one of the following videos:

    The picture below is from the first video.


    A concrete example is available here, and a powerpoint template is here.

    How the session could look like, in which order to use the hats etc, then one could have a look here. With some examples:

    First ideas:

    • blue – definition of subject
    • white – ready knowledge
    • green – generating ideas

    Problem Solving:

    • blue – definition of problem
    • white – available info
    • green – possible solutions
    • yellow – reality check solutions
    • black – weak points solutions
    • white – connect to info
    • blue – draw conclusion

    Decision Making:

    • blue – topic of decision
    • green – offer alternatives
    • white – factual situation
    • yellow – suitability alternatives
    • black – un-suitability alternatives
    • red – making the decision
    • black – assessing decision

    Tip: flip mirror can be handy for taking photos with telescope

    I recently purchased a flip mirror and I find it very usefull when trying to take photos with telescope. In this setup one can both view the target visually and take photos. It takes some time to get the camera and visual eyepiece adjusted, but after that is done, then one only need to flip (turn) the mirror.


    When using high magnification, then eyepiece projection is good way to achieve that. The picture below shows the 2 eyepieces that are needed in this kind of setup. Camera is connected on the left (not in picture).



    The photo below shows other ways to connect a camera to an eyepiece. They do work, but are not as practical as flip mirror with DSLR. It is also possible to combine these two, and use these adapter to flip mirror in place of DSLR …

    loosing weight by walking, the first 1 million steps

    With the help of an Activity tracker it might be easier to achieve your weight loosing goals. These trackers take care of the tedious work to log everything. Just place the activity tracker on your wrist, and start walking…

    This blog will show some real results, when using an activity tracker during the first 1 million steps.

    This huge number of steps came as pleasant surprise, and was a good milestone to write this blog. When buying the activity tracker, the intention was to loose weight; especially by walking.

    In this period of 1M steps, one could loose weight for about 7-8 kg, which is close to 1kg/week.

    The figure below shows the weight (kg) for the 56 days (close to 9 weeks).

    The figure below shows the number of steps for each of the 9 weeks.

    The figure below shows the estimated extra Calories (C = kcal), over BMR, for each of the 9 weeks. (The numbers are given by the activity tracker).

    Lessons learned:

    • One needs at least 2 different tracks: one for regular short walk (min 1h), and the other for longer exercise (min 2h).
      • If you can afford, then take the long track. It is more difficult to get started than to continue walking…
      • (in my case, my favorite tracks are short walk “1h15min” and long walk “2h35min”)
    • Don’t force the walking speed too much, the duration of walking is actually even more important as this is about fat burning and not competition
    • There is such a thing as limited speed of change (weigth loss), even if you walk a lot one day, you will not loose all weight in one day; the affect takes longer to adjust
    • Yes, you can eat. If you increase your exercise (walking), then there is less chance to get more weight. Yes, sometimes the weight jumps after party, but it is not permanent.
    • Yes, you can have day(s) without exercise as long as you try to maintain some routine and monitor that you don’t start to gain weight too much.
    • At the end, it is about routine and habits. Walk when you feel for it, it can clear your mind 🙂

    About activity meter

    • the activity meter on the wrist is only the data collector. The collected data is synced with the server, and that location varies depending on company. Some persons might prefer to choose to select a manufacturer that keeps the exercise data in EU…
    • The estimated calories varies depending on if you have HR (heart rate) measurement active or not.
      • With HR active, it records more calories
    • the battery does not last “long” if you have HR, GPS or bluetooth active
      • bluetooth can be used if you install an android app
