From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Armbian Style MOTD for x86 (cdn.tcb13.com)

Hello,

I've been using Armbian on a bunch of ARM SCBs and they have a very nice MOTD on SSH login that shows CPU, RAM, Storage and networking infromation.

Is there anything similar for a regular x86 machine? I tried to grab the scripts from a NanoPi M4v2 board but had to change a ton of stuff to get it working on x86 and it isn't portable as AMD and Intel report temps differently. Or... does anyone know if their x86 version has it working and where to get?

Just for reference I'm talking about this: https://cdn.tcb13.com/2023/armbian-motd.jpg

Thank you.

There's a bunch of options on github, some of my favorites:

https://github.com/sophieforceno/motd-scripts

https://github.com/HermannBjorgvin/motd

https://github.com/yboetz/motd

Thanks!

Why not write your own version? Getting the temperatures is easy and portable with the sensors command from lm-sensors. The rest of the info is easy to get using various commands (e.g. uptime, free) combined with a bit of sed/grep/awk for formatting.

That's what I've been doing but... https://lemmy.world/comment/2990793

Looks like that config info might be defined in this script

[–] [email protected] 1 points 1 year ago* (last edited 1 year ago) (1 children)

Yes, that script depends on /usr/lib/armbian/armbian-allwinner-battery that, in turn, depends on the armbianmonitor service. :(

Can’t you cut out the battery code since your screenshot indicates it wasn’t used? I should be clear that you’ll have to edit some bash scripts to make what you’re asking for happen.

That's an example, for instance the CPU temps depend on another os those files that is written by the armbianmonitor service... and I don't want to run that service on a generic machine. In the past I modified the script to read temps from lm-sensors but that doesn't seem to be very portable as both Intel and AMD have multiple variations on way they report the temps.

This is why I'm mostly looking for an alternative.

Does anyone else prefer no MOTD? You can SSH into your server without clobbering your scroll back buffer. It makes everything feel more seamless.

There's Armbian for x86... https://www.armbian.com/uefi-x86/

[–] [email protected] 1 points 1 year ago (2 children)

I'm aware... but where can I get the included MOTD without having to burn the image and whatnot?

[–] [email protected] 1 points 1 year ago

Sorry. Can't help you there.

[–] [email protected] 1 points 1 year ago (1 children)

you should be able to drop an executable in /etc/update-motd.d/

also have a look at libpam-motd or at the systemd scripts that ubuntu uses

[–] [email protected] 2 points 1 year ago (1 children)

Yes... but this armbian thing has too many dependencies I wouln't want to run the armbianmonitor service just to power this up.

[–] [email protected] 1 points 1 year ago

sorry, I should have replied as top comment. I meant that on plain debian you can put executables in /etc/update-motd.d. That should do, otherwise have a look at libpam-motd , or steal the systemd scripts from an ubuntu install

I managed to mount the image and extract the files, however it still fails on a regular Debian box, x86 as a few tools seem to be missing:

Grabbing armbian-allwinner-battery doesn't help as it depends of stuff like /etc/armbianmonitor/datasources/ambienttemp

Dude, I know your IP now. You're hacked!

😂 😂 😂 god damn it. You took so long.
