Setup CentOS Network from Command Line

-
For CentOS minimal install, the network device is disabled by default. To turn on the device, we use network manager command line tools

First we need to check for if the network device exist:

nmcli d

Once we confirm that the device is present, use another tool to activate the network. Use the command below to activate the network.

nmtui


Select "Edit a connection".


Select the network device and choose Edit....


Most of the setting are default, just make sure that "Automatically connect" is checked. Select OK when done.


On the main screen, select Activate a connection. Once the connection is activated, we are good to go.


We can check the network connection using the command below:

nmcli connection show

Revive Old Mac Mini (2009) with Linux

We have an old Mac Mini (late 2009 version) lying around. The latest Mac OS X it could support was Mac OS X El Capitan. The machine is still good although the DVD drive does not worked anymore.  Apple will drop security update for El Capitan very soon. Running OS X El Capitan without any security update is not an option.  Instead of disposing a good piece of hardware, we can install Linux. However, before we start playing around with the Linux installation, we need to take stock of the hardware capability. We might need to upgrade some hardware so that we can run Linux smoothly. Mac Mini 2009 Specification This Mac has Core 2 Duo CPU (P8700) running at 2.53GHz. It support PC3-8500 DDR3 RAM running at 1066MHz. This Mac Mini has a Nvidia Geforce 9400M video card. It support 2 display output. Wifi specification is 802.11a/b/g/n. This is pretty high end at the time.  However, this WiFi uses Broadcom chipset (BCM4321), which is not very well supported in Linux since it

RealVNC is a commercial company that sell VNC license for the enterprise market. However, the company allow home user to setup VNC server for personal use. The limitation is that you are only allow 5 connection. User must register an ID with the company. The configuration of your VNC will be stored on the company's server.
