The file /etc/network/interfaces has auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 172.16.6.63 netmask 255.255.240.0 gateway 172.16.0.1 broadcast 172.06.0.1 Is that broadcast address a typo? Are you on Jessie? If so you should use kolban's way to set a static address. Exec...

Greetings. I did copied a smaller system to a bigger partition, with rsync. I think it would work on a smaller one either. I couldn't be sure on the command line, it could be "rsync -avx". -a means archive mode, details in "man rsync" -x means don't cross file system border, as there could be some m...

Greetings.

When you configured your static IP, did you tell it the gateway address and DNS address as well?

allfox

Great~ Thank you guys!

So there is a repo providing headers out there, I didn't know that.

Sorry but nothing happens. Have you verified with a Debian 8 raspberry pi? My idea is that Raspberry does not call the script. allfox@pi1 ~ $ cat /etc/debian_version 8.0 And in my /var/log/syslog during boot: 3689 Jan 10 12:59:02 pi1 ifup[627]: eth0 is Uppppppppppppppppppppppppppppppppppppppppppppp...

Try this:

#!/bin/sh
if [ "$IFACE" != eth0 ]; then
exit 0
fi
/bin/echo "Upppppppppppppppppppppppppppppppppppppppppppppppppppp"
exit 0

allfox

Mine works.

Could you post your script?

Did you give it execution privilege?

Greetings. I couldn't enlarge your pictures. I don't know experix, but I would like to tell some story about timing. :) From my understanding, you mean if the interval is too small, Pi would have difficulty to catch up, is that right? I agree with that. I recently tried to set up a network traffic s...

I haven't tried Arch, so couldn't be sure. It seems should work, as my understanding of that web page.

It comes to my mind that, while the physical universe particle has an Uncertainty principle out there, the computer's memory has finite bit states, and can be known accurately. Is that means 1 What could a computer system do is finite. 2 More memory, more things could a computer system done. ?

The SDCard is the long term storage, it's the equivalent of a hard disk on any other computer and is connected on an input/output device. There's either 256MB, 512MB or 1GB of random access memory (RAM) which is tightly coupled to the processor. Let's talk about our understanding of the universe. :...

Greetings. Maybe you could give Raspbian Lite a try, it is described as "Minimal image based on Debian Jessie". The Arch Linux for PC won't work on Pi, however, you could try the ARM version: http://archlinuxarm.org/platforms/armv7/broadcom/raspberry-pi-2 And if you are brave enough to build your ow...

Cant i just attach some wires to ARM or whatewer memmory chips to clean/restore to default those? My textbook told me a computer has 5 parts: Controller, Processor, Memory, Input, Output. ARM CPU is the Controller and Processor. Not the Memory. So even if I want to erase/restore some memory, I won'...

I feel paranoia is difficult to cure. It's sometimes not because lack of knowledge, but lack of trust. Maybe it's always about trust from the very beginning. I've just tried set up a proxy far away(real distance, should imply hop either) from a Windoz guy. He can't reach his bandwidth speed via the ...

Greetings.

Try change #driver= to driver=nl80211.

The rtl871xdrv shouldn't be in normal hostapd installation, aka via apt-get. If you downloaded your hostapd from somewhere else, please mention that.

Could you tell us which device cause the reboot when you measure voltage step by step? I don't quite know about HDMI to VGA cable. I saw some of those adapter have their own power input. And some of them have their own audio output, so you could remove audio from Pi. Suggest adding max_usb_current=1...

allfox

Greetings. Could you make sure that is really a SD card, not a Micro SD plus SD adapter? I just think vendor would not put a SD card with Pi B+ as a set, that would be embarrassing. Some Micro SD card comes with a SD adapter. You can pull the Micro SD card out of it. This one on Amazon has an adapte...

I haven't tried upgrading Debian on Pi. My old Ubuntu experience told me: 1 It would be easier to install a fresh new OS than upgrading it. Because although you might save some download time by upgrading, however it would take you more time to make old settings work with the new OS. Example on Raspb...

My router has a button on it, so is my adapter.

They seem named WPS.

I never push those dangerous little red button.

Edit: I don't know if they would work on Pi. Some other device does able to connect via this.

The idea behind LoRa is to provide long range but low power communications for Internet of Things devices. That is low power consumption but unlike WIFI a much longer range, 5, 10, 15 or so kilometers. In order to get that kind of range it uses very low data rates, so no good as a regular IP connec...

I shall ask this earlier.

Could you tell me what is hunt the LoRa game? I googled and it looks not on the first page.

Greetings. https://www.raspberrypi.org/help/ is great. I feel it would be better to get a Pi 2B for starters, its faster and easier. I suggest the first thing to do is booting the Pi up. However it could be a boring thing for a child: Reading all those doc and in return only get to the beginning. So...
