Windows: Determine uptime from command line

Hi,

unlike Linux, Windows has no builtin uptime command to see when the operating system starts.

But nevertheless it’s possible. Use the systeminfo command.


c:\> systeminfo | findstr /i time
System Boot Time:          05.06.2014, 21:05:06
Time Zone:                 (UTC+01:00) Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna

Note: If you have installed a language different then english replace time as filter which applies to your language.

Raspberry Pi: eibd with a KNX USB Interface

Hi,

a reader of my post asks me if it possible to connect the eibd bus with a KNX USB Interface instead of the TPUART board.  These interfaces are available by several vendors(Siemens, Gira, Merten etc.).

I have no KNX USB Interface for testing and therefore Bastian Herzog did that part and supports me to improve the script. Very special thanks to him. Together we have get this started.

As descripted in the previous post setup your Raspberry Pi with raspbian:

VMware ESXi: Setting up NAT with a linux virtual machine

Hi,

other than the Workstation, VMware ESXi does not has the functionality to “NATting” virtual machines network traffic into a public network.

My approach to implement NAT is a virtual machine with a slimmed-down (Debian) Linux.

These virtual machine has two network interfaces. The first interface is connected to a vSwitch called “Public LAN” with access to the public LAN, the second interface is connected to a vSwitch which has no physical adapter attached to and is called “NAT Network”. On the NAT interface a DHCP server is assigning IP Addresses.
