MX Backup – Postfix Email Server |

Posted by jpluimers on 2017/11/09

Interesting as it has steps for both OpenSuSE and Debian each well suited for running on a Raspberry Pi.

[WayBackMX Backup – Postfix Email Server |

It seems postfix is a lot easier to configure than sendmail so I already like it.

First I need to read a bit more in Postfix greylisting.

I’ll need to catch up on Sam’s other parts with the postfix tag as well:

bash: `printf` supports `\e` just like `echo -e` does

Posted by jpluimers on 2017/11/07

Learned a few things when modifying

Note: `printf` supports emitting `ESC` (ASCII character `\033` aka `27` aka `0x1B`)as `\e` the same way that `echo` does

Format strings are at
%-10s means left adjusted (aligned) string of length 10



I was investigating how the colour definitions on my OpenSuSE system actually work internally so I added some extra output: ${TYPE} and ${COLOUR}.

Raspberry Pi brexit – changing your locale away from GB when you’ve a different keyboard

Posted by jpluimers on 2017/10/02

A while ago I wrote about -bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8) on fresh Raspbian on Raspberry

I thought my locale issues were solved and they sort of were. Until I had to logon locally and managed to get one or more of these characters in my password:

  • ~ (tilde)
  • @ (at)
  • # (hash)
  • \ (backslash)
  • | (pipe)
  • " (double-quote)

Then logon would fail locally but work via ssh. Go figure!

Lot’s of people outside the UK using their Raspberry Pi with keyboard and monitor will now say: you’ve the default GB keyboard layout and your keyboard is not GB.


This is how US keys look when using a GB keyboard layout:

As a Linux administrator you’ve got various tools to use in order to configure network connections, such as: nmtui, NetworkManager GUI and nmcli in Linux
