Reinstalling Raspberry Pi

Raspberry Pi file and ftp server

Today is the day to reinstall my raspberry pi which acts as:
ftp server
samba server
forked-daapd server for my flac collection
network bridge for my upstairs room

This particular pi has a "Segmentation Fault" when issuing certain commands like "sudo su" or "apt" commands. My guess is that the SD Card is corrupted, I know this from previous problems I had with this raspberry pi.

So I made backups of all important stuff like config files etc.. Let's see how it goes!

openSUSE Samba shares not showing up in file manager

Samba shares do not show up in file manager

OS: OpenSuse Tumbleweed VERSION_ID=“20200331”

File to check: /var/log/samba/log.nmbd

So my samba network was not visible at all in xfce on OpenSuse. In this case it was not the firewall or samba version, it was just dns resolving. I noticed my OpenSuse VM still had localhost as the hostname and in

/etc/samba/smb.conf

I had the following settings active:

Using PASS password manager multiplatform

Submitted by egbert on Mon, 10/28/2019 - 11:40

What I need:
1. A secure password manager
2. No hosted database or cloud stuff
3. No database at all!
4. Based on standards
5. Encrypted

Like many I really do not like password managers. They suck like big time and are a lot of work to keep going. But I did need something to organize all my passwords. I did try the simple text file with a list but that didn't seem to secure and kind of a hassle.

Create an SSH key pair

Submitted by egbert on Fri, 09/14/2018 - 06:41

On the source machine:
Step 1.
ssh-keygen -t rsa -C %user%@%target% Enter a passphrase if you want, it is not necessary
Step 2.
cat ~/.ssh/id_rsa.pub | ssh %user%@%target% 'cat >> .ssh/authorized_keys'

Authorized Keys file on target machine
.ssh/authorized_keys is a file on the target machine and should be mode 600.

Raspberry Pi Touchscreen Brightness Control

Submitted by egbert on Fri, 04/06/2018 - 11:20

Using the "echo" command
echo %n% > /sys/class/backlight/rpi_backlight/brightness

%n% represents value between 0 - 255

Change the file permission for /sys/class/backlight/rpi_backlight/brightness to 666. This is not saved on reboot!

To make a permanent change:
1. sudo nano /etc/rc.local
2. Add 1 line above the "exit" line
3. Type in "sudo chmod 666 /sys/class/backlight/rpi_backlight/brightnes"
