Mikrotik RouterOS 6.41 changes

Been a little busy the past week, but did notice Mikrotik RouterOS 6.41 released on 22nd Dec 2017.

It has some significant changes that I wanted to highlight from the changelog and quickly show the changes in the winbox interface.

!) bridge – implemented software based vlan-aware bridges;
https://wiki.mikrotik.com/wiki/Manual:Interface/Bridge#Bridge_VLAN_Filtering

!) switch – “master-port” conversion into a bridge with hardware offload “hw” option;
https://wiki.mikrotik.com/wiki/Manual:Switch_Chip_Features#Bridge_Hardware_Offloading

!) detnet – implemented “/interface detect-internet” feature;
https://wiki.mikrotik.com/wiki/Manual:Detect_internet

The switch changes is the one that got my interest, as this is the one that I have known and used since I first started to use Mikrotik hardware. So now I have to get my head around the fact it has changed.

routeros-pre-6.41-interface
routeros-post-6.41-interface

You can see from the images above that Master Port is no longer used and/or available under your interfaces to group interfaces together as switched ports. This is now done differently.

Upgraded one of my routers and I think I understand how this change impacts future configurations and setup process.

Intel 7th Generation Desktop vs Laptop CPU sample

Intel Core i3 7100 (Desktop CPU)

distributed.net RC5-72 workload sample – 80 packets.

[Dec 27 09:41:10 UTC] RC5-72: Summary: 80 packets (80.00 stats units)
                      0.00:37:47.78 - [149.06 Mkeys/s]

Intel Core i7 7500U (Laptop CPU)

distributed.net RC5-72 workload sample – 85 packets.

[Dec 27 11:04:28 UTC] RC5-72: Summary: 85 packets (85.00 stats units)
                      0.00:46:22.95 - [128.69 Mkeys/s]

Surprised that the i3 Desktop has the slightly better throughput on this workload. I somewhat expected that the i7 to win. The interesting thing to note though is that of course the i7 laptop CPU would be using way less power, thus generating much less heat. It makes me wonder though… how would an i3 laptop CPU perform in this test when compared to the i7 laptop CPU. Unfortunately I do not have one to test.

New Magazine Subscription

I always get a magazine subscription every year. But honestly haven’t been enjoying the magazine I would typically get in Australia. Linux Format recently got my interest, and they had some specials over the Christmas period which has help to sway me over. Tonight I noticed they had even further discounts – another 20% off. So I jumped on the bandwagon and signed up for a 12 month digital only subscription.

New Tablet – Samsung Galaxy Tab A

Merry Christmas everyone.

Today I got a new tablet. My wife purchased me a Samsung Galaxy Tab A (2017) model. This will enable me to use it in situations where a laptop doesn’t really allow. The tablet is very handy when on public transport and relaxing on a cruise ship. Will give me a chance to load it with content and consume as needed.

New PC Build

Finished off the PC build tonight, however hit a few snags. The Corsair H60 radiator is much larger then the Corsair H55 version and as such cannot be installed in a Corsair Spec 03 case on the rear. This impacts the PCIe video card slot. If I had got the Corsair H55 this wouldn’t be a issue, as I know it fits based on previous experience where I have one installed in another machine (tempted to honestly swap H60 out for a H55 in coming months).

For now as pictured below, the Corsair H60 is intalled in the top of the case. The only place it can fit in this case without impacting my video card.

So far I am very impressed with the system. It is able to encode a 1 hour 30mins video file into a Android 720p30 mp4 file with 2 pass enabled in about 23mins. The same test on other machines ranges from 1 hour to 2 hours depending computer used. So massive improvement.

Battlefield 1 also runs great. So I am very happy.

This machine I want to last me a good 5-6 years. The only things I want to replace will be items that die outside of warranty, which might typically be hard drives etc.

Upgrades include in the future for the machine..

  • Additional 16GB memory kit
  • Additional M2 SSD drive (500GB or 1TB model).

Will be sure to post more about this computer as things happen.

New PC hardware arrived

My New PC hardware arrived. I ordered this on Friday and paid for it yesterday.

I ended up deciding on the following items;

  • Intel i7 7700k
  • Asus Z270M-Plus (Prime z270) mainboard
  • Corsair H60 Liquid CPU cooler
  • Corsair CX600 Power Supply
  • Corsair 16GB (2x8GB) DDR4-3000Mhz Vengeance LPX Dimm
  • Asus Dual GTX1070 8GB Video card

I already have Monitor, Keyboard, Mouse, Samsung M2 250GB SSD, Optical Drive and 3.5″ Hard drive.

I opted to get the Intel i7700k for the faster base clock speed, but then got the faster memory and Z270 mainboard in case I wish to overclock it. As I know that it’s possible per Adam Fowler¬†and his recent PC build.

Spa finally connected to wireless

It’s taken me a few weeks, but I finally have our Spa connected to our wireless network.

Unfortunately I worked out very early on that the wireless module in our Spa couldn’t see the main house wireless. So the plan was to install an external wireless access point. That task was completed some weeks back using a Mikrotik wAP.

Today I finally used the SVLink iOS application to configure things (as the Android version sucks). It’s now connected to our wireless network. This means I can now control all the Spa functions for the application on our phones. So you can increase the Spa temperature before getting home and it will be ready to use at that perfect temperature.

Screen capture below from the iOS application.

 

Australian residents can purchase Mikrotik hardware from my favourite supplier in Geelong – Duxtel. Highly recommend them.

Ubuntu 16.04, tvheadend and SiliconDust HDHomeRun

Decided I would compile Tvheadend again and install it on a Ubuntu 16.04 host. Below is some of my notes that will help others with this installation and problems I hit along the way.

Required packages.

apt-get install unzip libcurl4-openssl-dev pkg-config git build-essential dvb-apps gettext libssl-dev cmake liburiparser-dev libavahi-client-dev
apt-get install hdhomerun-config

Installation/Compiling steps.

wget http://ftp.gnu.org/gnu/libiconv/libiconv-1.15.tar.gz
tar zxvf libiconv-1.15.tar.gz
cd libiconv/
./configure
make install

I created a user called “tvh” which will be used for the running of the software, this way it doesn’t run as root. Plenty of guides about that detail how to create your user and associated correct group assignments to it. So I won’t cover these steps/operations.

Noticed when I executed the product post being compiled i was getting an error.

tvh@oscar:/usr/local/bin$ ./tvheadend
./tvheadend: error while loading shared libraries: libiconv.so.2: cannot open shared object file: No such file or directory

As you can see from the output below, it’s a library issue.

ln -s /usr/local/lib/libiconv.so.2.6.0 libiconv.so.2.6.0
ln -s /usr/local/lib/libiconv.so.2 libiconv.so.2
ln -s /usr/local/lib/libiconv.so libiconv.so

It would appear that Tvheadend has had some improvements since the last time I compiled and installed it.

As shown below we now see a new logo for the product, and now get a wizard which helps with the setup.

Tvheadend is such a great application.

New Internet Provider

Yesterday after getting so much packet loss and the fact that I have had enough of the poor ongoing performance from iiNet. I couldn’t stand it any longer and jumped ship (read: provider).

OCCOM became our new service provider as of about 10am today. Of course speedtest result has to be posted.

5766801524

Of course doing some download tests during the day has surpassed the real world speed I got on iiNet when the issues had been going on. Even my evening tests surpass those of the iiNet service. Not sure what happened to iiNet network, but only getting about 50-80kb/s from ftp.iinet.net.au and about double that for mirror.internode.on.net during evening reflects just how bad things are. Those same tests now on new isp massive difference.

Get over 3 MB/s to mirror.internode.on.net right this moment.. couldn’t even get half that at this time of night on my iiNet service.
