Debian has been my primary Linux distribution of choice since 2003. That’s twenty years! How time flies! I haven’t ever worked as full-time server administrator but running and operating various kinds of systems have always been part of my skills, and it has made it possible for me to leverage wide range of tooling required […]
A long time ago I discovered screen. It made it possible to start applications in Linux and then disconnecting the SSH session, without stopping the applications. It was magic: otherwise the the applications just terminated if the SSH connection was lost. Then I heard about tmux. It was like screen on steroids! I could split […]
This is a plain list of actions I did when creating a MariaDB database master-slave replication setup. It is assumed that you already know why you want to create such a configuration and how you can use it in your case. Some links anyway: Global Transaction ID (mariadb.com): “[…] it is generally recommended to use […]
A short memo how to backup any PostgreSQL database: In .pgpass (you should keep this file protected): netbox-db-backup.sh: That will also find and delete backup files older than MAXDAYS.
I’ve “always” used PuTTY as my SSH client on Windows. And now, in 2019, I realized that there really are some settings in PuTTY that can make a difference! Here is my earlier normal view: Bash prompt and the colors looked like this: Not very modern, right? After some adjustments, here they are now: For […]
My trusty old VDR box started behaving erratically: sometimes the IR remote didn’t do anything. Rebooting the whole box usually helped, but not always. Eventually I was able to narrow the problem down: for some reason the LIRC serial driver did not correctly detect the IR receiver in the serial port at the boot. I […]
How to identify your Raspberry Pi, maybe built in a nice and sealed box? Here is how: $ cat /sys/firmware/devicetree/base/model;echo Raspberry Pi Model B Rev 2 $ $ cat /sys/firmware/devicetree/base/model;echo Raspberry Pi 3 Model B Rev 1.2 $ $ cat /sys/firmware/devicetree/base/model;echo Raspberry Pi 3 Model B Plus Rev 1.3 $ $ cat /sys/firmware/devicetree/base/model;echo Raspberry Pi […]
I have been a ThinkPad user since 2007. The first one was Z61p I think, and after that I’ve had (either my own or employer-provided) T61, T420, T430s, T540p, X1 Carbon 4th gen and now X1 Carbon 6th gen (or X1C6, as they call it in some forums). In T540p the big disappointment was the […]
Put these in your .vimrc to enable for example Python syntax coloring and indenting in Vim: syntax on filetype indent plugin on
Just wanted to say this: In Vim under Cygwin the user’s vimrc is not looked up as ~/.vimrc. One of the correct locations is ~/.vim/vimrc. It will be read whether you start your editor as “vi” or as “vim”. You can use a template to start with: Markku@T540p ~ $ mkdir .vim Markku@T540p ~ $ […]
