Somfy Smoove Origin RTS Protocol | PushStack

Posted by jpluimers on 2016/05/24

Interesting: Somfy Smoove Origin RTS Protocol | PushStack a base to start Hacking Somfy.

The Somfy protocol is tricky as it uses rolling keys.

More interesting links:

These are in Dutch, but very interesting as they show how to do reverse engineering and getting it to work hardware wise:

View Headers and Source from Outlook .msg file – via Super User

Posted by jpluimers on 2016/05/23

Sometimes people give you .msg files saved from Outlook instead of forwarding those mails by e-mail.

Opening a .msg file requires Outlook.

You don’t need to bind Outlook to an e-mail account for this (so you can skip those steps when asked the first time Outlook opens). An Office installation that includes Outlook suffices.

After opening the message:

  1. Open the toolbar if it’s not open yet
  2. Under “Move” choose “Actions” -> “Other Actions”
  3. Then choose either “Message Header” or “View Source”

For some HTML messages, “View Source” is not available. I’m not yet sure why.

“Unable to connect to the MKS”: the port 902 problem.

Posted by jpluimers on 2016/05/23

A message like “Unable to connect to the MKS” usually does not mean you have reached the maximum of 10 connections for a VM.

Usually it means there is some network issue, like a firewall or router misconfiguration.

Port 902 is used (both TCP and UDP) to provide (among others, hence MKS) console connections.

The default MKS port is 902, and you cannot change it.

For vCenter it is even worse as you cannot even go through NAT:

About the only solution is to tunnel through SSH: VMWare vSphere Client Remote Access via SSH Tunnel and redirect ports 443, 902 and 903.

The Sons of Kahn and the Witch of Wookey • The Register

Posted by jpluimers on 2016/05/20

Verily, they did make support for the Internet of Things.

As always, brilliant writing. For instance:

  • “But there was also the Youth Faction, who were indeed very young, some being barely in their mid-forties.”
  • “Ask a Delphic question, get a Delphic answer” –

Multi-WAN routers compared

Posted by jpluimers on 2016/05/20

Mikrotik have statistics and way more features. Of the not so good features on the TP-LINK ER-5120 multi-WAN router (none of which are mentioned in their documentation), the worst 2 are:

  • Virtual-Server table can only handle 32 incoming port redirects
  • no IPv6 support
  • both incoming WAN and outgoing NAT isn’t very stable (my guess it’s a NAT table filling up)

Less than two decades of Google Data Centers – from corkboard x86 hardware via GPU to TPU – now they make their own chips too

Posted by jpluimers on 2016/05/20

First corkboard production server by Google in 1998

First corkboard production server by Google in 1998

Remember the image on the right? It was the first “corkboard” production server Google used in 1998 (it’s a museum piece now).

From there they were using commodity-class x86 server computers running customized versions of Linux for a “long” time which around 2005 even got their own 12V battery as UPS inside the machine and running 1160 machines in a 1AAA shipping container.

Later whey started using a mix of CPU and GPU increasing the performance per watt and recently went from 12V to 48V and even contributed 48V DC Data Center Rack to Open Compute.

In the mean time, Tensor Flow and AI got even more important for Google and during the Google I/O 2016 keynote, they revealed yet another step: TPU chips especially made for TensorFlow providing even better performance per watt for machine learning than GPU. The TPUs are not FPGAs (popular for instance when mining BitCoins), but ASICs that perform orders of magnitude better.

So in about 18 years, Google moved from cleverly assembled commodity hardware to highly specialised custom chips.

Exciting times are ahead of us. I’m really looking forward to the next steps.

Nice diskinfo alias showing du, df, btrfs, parted, lsblk

Posted by jpluimers on 2016/05/20

I bumped into a disk full issue again because of the btrfs/snapper combination in openSuSE and df basically lying about the disk space, so I w rote this Nice diskinfo alias showing du, df, btrfs, parted, lsblk.

You can combine this with A bash script to btrfs snapshot details like disk sizes (requires btrfs quota to be enabled) to find out which snapper snapshots take up a truckload of space and might be safely removed.

Android ADB over TCP/IP

Posted by jpluimers on 2016/05/19

Android ADB over TCP/IP can be a bit of a pain to setup. Some devices have a built-in option to enable this (by default on port 5555), otherwise you have to connect through USB first, then use ADB to enable TCP/IP:

adb tcpip 5555

I got it to work without being root, but on some devices you need to be.

See these links for more information:

Note that while writing this, ADB For Chrome could not run over TCP/IP.

networking – Is there a command or application similar to ipconfig? – Android Enthusiasts Stack Exchange

Posted by jpluimers on 2016/05/18

Trick:

use “netcfg” to list all available devices

It will show you the IP addresses associated with them too.

On my OnePlus One, it was wlan0.
