Restarting networking on a Raspberry Pi ( debian, raspbian OS ) 2017-11-11 22:32 UTC
I had trouble restarting networking on a debian/raspbian system when the wifi disconnected.

This didn't work:
service networking restart

This didn't work either:
/etc/init.d/networking restart

But this worked:
ifdown eth0
ifup eth0

Simeple as that.
Or in a pinch:
ifdown eth0 && ifup eth0


In raspberry pi, they no longer use ifup/ifdown. They use dhcp entirely.

You can try to bring it up/down with:
ip link set dev eth0 down
ip link set dev eth0 up

You can try to restart dhcp client:
sudo systemctl restart dhcpcd


A notable tool to use for the pi: wpa_cli: LINK


pi-hole.net: Network-wide ad blocking via your own Linux hardware 2017-11-09 22:28 UTC

No client-side software required
Install by running one line on the console:
curl -sSL https://install.pi-hole.net | bash

That GETs a script and pipes to a shell.

It removes ads, but what do they do with your DNS traffic information? Do they resell it?

Raspberry pi introduces the Raspberry Pi Zero W - W for wireless for $10 instead of the current zero for $5USD. 2017-02-28 14:04 UTC
The RPI 0 now includes wireless 802.11n and bluetooth 4. Excellent move. The W also retains the camera port.

Update 3/4/2017:
I picked one up at Micro Center tonight. It was in stock just a few hours ago. They had many bins full. Looks like at least a few thousand. Its selling at $10 for one. $15 for 2 or more and $20 for 6 or more. So instead of being cheaper in quantity, you are penalized for buying more.

Here's how the antenna works:
