RaspbianOS does not create standard user pi with standard password raspberry any mor. That's good, During first boot you have to define the user and it's password now. If you setup your Raspberries headless you now have an issue.

Sometimes you don't want to restore a whole system but restore only some files or directories. That's not directly supported by raspiBackup. But given the fact raspiBackup was designed to restore a system from it's backups with plain Linux tools it's possible for all three backup types. But all activities have to be done on a Linux system because the tools used to retrieve the data are Linux tools. The most convenient way to retrieve backup data is offered by rsync. dd and tar require to execute some commands in the command line first.

Every Raspberry beginner starts with a NOOBS image, which is listed by raspberry.org first as the suggested image to use (See https://www.raspberrypi.org/downloads/)

NOOBS allows to start different operating systems which is useful when you want to evaluate the different alternatives to decide which is the right one for you. Unfortunately most of the people continue to use NOOBS when they have decided which OS to use. But that's the point to setup a new image with only one operating system.

Why?

NOOBS is no normal Linux system and has various quirks which causes a lot of headache sooner or later. If you ask for help if you have issues with NOOBS there is low probability you will get any responses. All experienced Raspberry users don't use NOOBS. As soon as you have decided which OS to use setup a new image and don't use NOOBS any more. This will make your life much easier when using your Raspberry.

raspiBackup supports NOOBS images in partitionorientierted backupmode . For production like systems it's suggested to create a single operating system image and backup this with raspiBackup in normal backup mode. the normal backup mode is also able to save an external root partition.

Synology offers Hyper Backup to backup your system- and application configuration and data for a worst case scenario. You should use external storage and can use a Raspberry which runs a rsync server. The initial backup takes quite long (multiple days) but all subsequent backups will take approx 1 hour.

To learn to use threading in Python you have to have a concrete problem to solve. Just use Raspberry Pi to connet 6 LEDs and manage them via GIO. On the following pages I describe how to customize my sample program to simulate tarffic lights. You also find a video which shows the program in action and a download link for the sample program.

The Raspberry Pi is a nice system which is used a lot of time to provide server services to be accessible from worldwide. That's Owncloud, a HTTP server, seafile or other services..

A VPN is the right way to access the server in a secure way. But if you want to give a lot of people access there is no way other than to allow access direct from the internet. Usually you use a DMZ for this but that's a feature a normal home router doesn't have. But now you should protect the Raspberry from internet access as far as you can and also protect your home network from access from the pi server when an intruder managed to get access to the pi. But note: If an the intruder managed to get root access then the iptables firewall can be turned off very quickly. So it's very important to get SW updates on a regular base.

Following article describes how to configure an iptables firewall to protect it from unauthorized access from the internet and to protect a local home network to be attacked from the server - just in case.

Raspberry Pi runs with Raspian, a Debian compiled for ARM architecture. Pi has an ethernet adapter and usually also an USB WLAN adapter is attached in order to be able to access Pi wireless. Given this hardware you can use the Raspberry Pi as an ethernet to WLAN bridge and/or as an access point with a cable connection. The following article explains how to create an ethernet to WLAN bridge on Debian and Raspberry Pi running Raspbian but will work also on other Linux distributions.

Update March 1st, 2014: Until kernel 3.6.11+ everything works as described below. Starting with 3.10.25+ ist doesn't work any more and a router has to be configured.

Update March 2018: There exists another way to create a kind of bridge by using an arp proxy. See here.

Raspberry Pi usually runs Linux (raspbian oder raspbmc). Linux allows to mount various external data sources. Following protocols are used commonly: SAMBA: smbfs/cifs, NFS: nfs, SSH: sshfs, FTP: cupsftp and Cloudspace: webdav/davfs. Following article explains with sample config files how to get access to these different datasourecs on the Raspberry Pi.

If you want to clone a SD image which was created on a Raspberry Pi and use the cloned SD on another Raspberry you have to execute one important additional step. Otherwise the Raspberry starting with the cloned SD card will not get a network connection.

Since a cople of weeks I own a Raspberry Pi. It's a nice toy. On one SD I installed XBMC. The other one has Raspbian. It took some time for me to get the Realtek 8192 USB WLAN stick to work. Now everything works fine.

Unfortunately I just got a kernel panic when I restarted the Pi. It's because I unplugged the power cable to restart the Pi quickly. Until now that's the way I did it until now and it worked fine. Even this tiny raspberry should be shut down the controlled way. Actually this was no big deal to recover: I plugged the SD card into a crad reader, connected it on my linux labtop and ran fsck on both partitions. Then my Pi started successfully again.
