Just call

curl https://download.argon40.com/argon1.sh | bash

If you run Ubuntu just call cd /tmp/ wget https://raw.githubusercontent.com/meuter/argon-one-case-ubuntu-20.04/master/argon1.sh chmod a+x argon1.sh sudo ./argon1.sh

Starting with Bookworm /boot/cmdline.txt was maoved to /boot/firmware/cmdline.txt. Therefore rpi-clone can unfortunately no longer update the UUID of the clone and the clone no longer starts. Details are described here on github.

raspiBackup.sh is also used to store backups on Synology. I don't have a Synology and cannot execute any tests to help on any issues which pop up. That's  why I created this page to allow users of a Synology to share their experiences with Synology and raspiBackup via comments.

raspiBackupInstallUI and raspiBackup right now writes messages in German and English only. But both are able to write messages in any language from a coding point of view (I18N). Unfortunately I'm a German native speaker and can speak English and a little bit French and thus I'm unable to add any other language (L10N) and need help on this. Anybody who is willing to help to add support for a new language other than German and English is welcome. Just add your interest in a comment on this page and I will guide and help you to add new messages in your native language to raspiBackupInstallUI and raspiBackup.

Right now following languages are supported:

EN - English
DE - German
FI - Finnish
ZH - Chinese
FR - French

Owncloud has a very poor performance on Raspberry Pi. But seafile runs very fast if running on nginx. There exist already a lot of instructions how to install seafile on raspberry so you will find links to these website on the following page which I used to install seafile. In addition I wrote down the sequence of steps I executed. It's primaily a combination of the various installation instructions which I found. My config files of seafile running with nginx can be downloaded as sample config files for your convenience. In addition there is a startscript for /etc/init.d available which starts seafile all the time when Linux ist started and and stops it when it's shut down. 

Characteristics of the seafileserver: foo.no-ip.org is used as external dns name, nginx (no apache), runs on secure https port and offers webdav services.

The backup directory created by raspiBackup contains all information required to restore this backup also manually with standard Linux tools. The following page describes how to restore a normal tgz backup.

I backup my xbmc config on my raspberry pi with Linux and rsync.

On windows it's unfortunately not that easy. That's why I describe in the following paragraph how to create a backup on windows and how to restore a previous backup. In addition I provide two windows cmd files which execute the commands in sequence and make the backup and restore much easier. Three tools are requiered on windows: putty, pscp und plink which can be downloaded from the putty page. If you kick off the backup command with the at command on windows you will have an actual backup all the time.

PiShrink is a useful tool to compress backups created with win32diskimager and other windows tools as a full backup to reduce them to a minimum size.

It's a hack and works a lot of time. Unfortunatey there are a lot of situations you get an ugly error message which are created because of missing checks in the code.

We now have a new Raspberry4 gibt, which in contrast to the previous versions becomes quite hot. So everybody is interested in the effectiveness of either passive or active cooling and whether this cooling suppresses CPU throtteling.

I wrote a small script check_throttled.sh which reads the current throttling states of the Raspberry with vcgencmd get_throttled and if throtteling happens or already happend the meaning of the throttling bits is reported.

Following page describes how to use a ZTE ML190 USB drive to receive SMS and forward them to another mobile phone number. But you can also send the SMS in an eMail or do other stuff. You can control any devices at home, i.e. turn on or turn off some device, open and close your garage and much more.

 

Update 5/2/2023

gammu requires Pyhon2 and will not be migrated to Python3. Therefore I now use smstools. Sample event handler smsevent includes a lot of sample code which only has to be adapted to the specific requirements.

Everybody running a server on a Raspberry with an open internet connection should protect against unauthorized access. There are various ways to protect. An additional protection is to restrict access to the Raspberry to specific IP ranges. The easiest way to do this is by using geoip and iptables and allow access from IPs from your country only. Actually this makes sense only if the server is used by you only and is no open server for everybody (owncloud, seafile, ...).

Execute following steps in order to install geoip on Raspbian Buster

Buster now uses nsf instead of iptables and requires a different format of the geoip files.

1) install xtables-addon

sudo apt install xtables-addons-common libnet-cidr-lite-perl libtext-csv-xs-perl libgeoip2-perl

2) Enable xt_geoip

sudo modprobe xt_geoip

echo "xt_geoip" | sudo tee -a /etc/modules-load.d/modules.conf

3) Download geoip files

mkdir /tmp/geoip

cd /tmp/geoip

/usr/lib/xtables-addons/xt_geoip_dl

4) Build geoip database now

mkdir -P /usr/share/xt_geoip
cd GeoLite2-Country-CSV_20190709 sudo /usr/lib/xtables-addons/xt_geoip_build -D /usr/share/xt_geoip

5) Add iptables rules to accept IPs from US and Germany

Example:

iptables -A INPUT -m geoip --src-cc DE,US -m conntrack --ctstate NEW -j ACCEPT

6) Create following script to update your geoip database on a regular base

#!/bin/bash
geotmpdir=$(mktemp -d)
OLDPWD="${PWD}"
cd "${geotmpdir}"
/usr/lib/xtables-addons/xt_geoip_dl
dir="$(ls)"
cd $dir
/usr/lib/xtables-addons/xt_geoip_build -D /usr/share/xt_geoip
cd "${OLDPWD}"
rm -r "${geotmpdir}"

 

Execute following steps in order to install geoip on Raspbian Stretch

1) Install the xtables-addons

sudo apt-get install raspberrypi-kernel-headers

wget http://downloads.sourceforge.net/project/xtables-addons/Xtables-addons/xtables-addons-2.14.tar.xz
tar xf xtables-addons-2.14.tar.xz
cd xtables-addons-2.14
./configure
make
make install

or

Kudos to @Basti

You can also use DKMS to build this module. Place source to /usr/src/xtables-addons-2.14 for example and create a dkms.conf in there. I have used the file shipped with xtables-addons-dkms_2.12-0.1_all.deb and edit the PACKAGE_VERSION="2.14" and
DEST_MODULE_LOCATION[0]="/extra". More infos about dkms (https://wiki.ubuntuusers.de/DKMS/).

 

2) Create a file /usr/local/bin/installGeoIP.sh and insert following code

#!/bin/bash
set -euo pipefail

set +e
if ! dpkg -l xtables-addons-common >/dev/null ; then
        apt install xtables-addons-common
fi
if ! dpkg -l libtext-csv-xs-perl >/dev/null ; then
        apt install libtext-csv-xs-perl
fi
set -e

if [ ! -d /usr/share/xt_geoip ]; then
        mkdir /usr/share/xt_geoip
fi

geotmpdir=$(mktemp -d)
csv_files="${geotmpdir}/GeoIPCountryWhois.csv ${geotmpdir}/GeoIPv6.csv"
OLDPWD="${PWD}"
cd "${geotmpdir}"
/usr/lib/xtables-addons/xt_geoip_dl
/usr/lib/xtables-addons/xt_geoip_build -D /usr/share/xt_geoip ${csv_files}
cd "${OLDPWD}"
rm -r "${geotmpdir}"
exit 0

3) Make this file executable and invoke it

chmod +x /usr/local/bin/installGeoIP.sh

installGeoIP.sh

4) Add iptables rules to accept IPs from US and Germany

Example:

iptables -A INPUT -m geoip --src-cc DE,US -m conntrack --ctstate NEW -j ACCEPT

 

Issues

If you get iptables: No chain/target/match by that name. error messages test whether the xtables_addons are installed correctly

modprobe -c | grep x_tab

should display a long list of modules.

modprobe xt_geoip

Should succeed.

depmod -a

may also help to fix the issue.

Unfortunately you need a USB A to USB A male cable which is very unusual. But there's a trick:  Remove the lower part of the case which includes the SSD and pug in the USB bridge of the Argon case. Now you can use a commonly used USB extension cable to connect the SDD to your PC. Now use any common methods to install an OS on your SSD.

Raspberry Pi is a very nice hardware which can be used to solve various problems. I notice an increasing number of questions how to get access to the local PI from the internet. From a technical point of view that's not a problem: Just forward the required ports from your router to your Pi and disable on xbmc the firewall. This may cause you serious trouble because some folks from the internet will be able to access your Pi and even your local systems in your LAN. You should follow some rules in order to keep them out.
