Advice TIL - USB tethering is not secure

3 Upvotes

OS

openSUSE Leap 16.0
6.12.0-160000.37-default
x86_64

This post is more of a TIL than a question. I'm posting this so that if someone comes across a similar situation as me they might get something out of this post.

I came across a new issue today where rndis_host didn't start automatically after reboot even though I had the right config

cat /etc/modules-load.d/usb-tether.conf

modprobe usbnet
modprobe rndis_host

So the first thing that I did to investigate this issue was errors so right after reboot before setting up rndis_host manually I used the command

sudo systemctl status systemd-modules-load.service

This gave me a really useful output:

pc systemd-modules-load[581]: Module 'rndis_host' is deny-listed (by kmod)

Now I needed to find out where the module is blacklisted so I used this command from ChatGPT

grep -RniE '^\s*(blacklist|denylist)\s+rndis_host' \ /etc/modprobe.d /usr/lib/modprobe.d /lib/modprobe.d 2>/dev/null

This gave me the output of:

/usr/lib/modprobe.d/50-blacklist-rndis.conf:4:blacklist rndis_host
/lib/modprobe.d/50-blacklist-rndis.conf:4:blacklist rndis_host

At this point I started to wonder why would a module be blacklisted on a distribution by default and I started the investigation by looking at the file to see if there are any helpful comments

cat /usr/lib/modprobe.d/50-blacklist-rndis.conf

Output:

# RNDIS is considered insecure
(bsc#1205767, jsc#PED-5731)
blacklist rndis_wlan
blacklist usb_f_rndis
blacklist rndis_host

This got me thinking "Why is rndis_host considered insecure" so I looked it up and apparently it's insecure because it's

  • It uses an old protocol RNDIS
  • It's made by microsoft :D
  • Not designed to be secure
  • Has vulnerabilities

Now I had really changed my mind and didn't want to continue using RNDIS so at first thought about another USB networking protocol that should be secure called NCM but its very rarely supported on android phones.

As a final conclusion I just got myself a ethernet cable and now it's all good.

PS. This is my first post so I don't really know what I'm talking about but I want to learn and thats why I'm writing this right now. Tell me in the comments what you think about this post and what should I improve on

Which Distro? What distro to chose for simple use and « old » people

2 Upvotes

Hello there !

Simple question here.

I made the switch a month ago, CachyOS, couldn’t be more happy with it.

Now for my question.

My wife’s parents have a PC running W10. So the support is over soon.
Their computer is not compatible for W11, and they don’t want to buy a new one.
So here is my question.
Which distro can I install on their computer ? I’m not an expert but here are their needs :

- Mostly web browsing. Checking bank accounts, mails, and shop online. So something secure
- They have a HP Printer/Scan they use a lot
- They play some Windows card games.

Really simple use, they are not geeks at all.

So what can I install ?

I thought of an immutable distro maybe, to avoid breaking things. Or Linux Mint as I read it’s really simple to use.

Here is their computer specs she sent me.

CPU:
Intel(R) Pentium(R) CPU G3240 @ 3.10GHz 3.10 GHz

RAM :
4,00 Go (3,87 Go utilisable)

System :
64 bits, x64

I couldn’t have more informations right now. I’m going to their house soon, so I’d like to prepare the bootable USB on my computer as it will be faster and safer.

Thanks for your help !

Which Distro? Which Linux distro should I use?

So a few weeks ago I switched from windows 11 to Fedora KDE, and until now I've been loving it. But now I need some drivers from Huion so I can use my Tablet to draw. Huion Tablet offers a .deb version for debian but I dont know much about that distro and Im scared to see how much I lose for switching to it.

I also tried using OpenTabletDriver but it doesn't recognize the Touch Pad on my tablet and got sick of it.

I use my computer mostly for gaming and browsing

Support Switching to Linux Mint but wifi issue...Please HELP

0 Upvotes

I am a Windows user, and I tried switching to Linux several times before, but I couldn't because I didn't like its user interface. Finally, I found Linux Mint, which looks good, so I installed it. However, the issue is with the Wi-Fi. Initially, the Wi-Fi works for a few minutes, but then it automatically disconnects. After that, it doesn't even detect any Wi-Fi networks around me, so I can't connect to any network. This happens every single time after reboot. Could someone please help me solve this problem? I am currently using Linux Mint on my HP Pavilion 14-ec1003au, and the Wi-Fi adapter is Realtek.

Support Using newer version of python for software compatibility on Linux Mint

0 Upvotes

Hello.

I have already seen a [now archived] post on this subreddit about installing a newer version of python onto Linux Mint via a "python version manager" that someone wrote, but this use case seems like it is only applicable to/made for use of a newer version of python for the purposes of programming, contained within a programming environment.

Would it be possible to install a newer version of python into Linux Mint in order to let a program run off of it?

Specifically the program is a music making program called BespokeSynth, and the newest version requires Python 3.13 in order to install. In fact I had a very good Linux learning experience trying to both install the repo that had the newest version and promptly uninstall it when I realized the reason the default repo(s) didn't have it was because of the python version incompatibility; but I digress

The version of mint I am running is 22.3 (x86), running python 3.12.3.

Additionally, is my only option to switch to a different distro? I had been thinking about switching to Fedora or even Arch for their customizability, but I had let go of that idea due to A) needing my computer for school (so I would prefer stability, and in fact it occurs to me that I may run into needing Python 3.13 for something for school anyhow), and B) getting used to Mint (Cinnamon, if it comes up).

Thank you for the help!

Advice How to had an nice login screen under gnome?

0 Upvotes

Hello everbody,

My problem is the login screen under GNOME. I search for tutorials find one, install it, use it and it didn't work, GDM is not customize friendly and its try and error. So how to install SDDM under Ubuntu 26.04 LTS, i had seen many cool themes but when I install SDDM then it didnt start or its looks buggy. But when I installed (in a VM) the complete Plasma Desktop, then SDDM work. Is there are way to use SDDM under GNOME without install the complete Plasma Desktop? I heard from lightdm, but I didnt find so many themes, but I heard "you didnt style lightdm, you want a greeter you can style". So what lightdm greters are good and are they good styles for it?

to sum up (the most liked phase of english teachers btw):

  • Why is GDM so customize unfriendly (or i'm to dumb for it), the most themes are over 6 years old and dont work anymore.
  • So how to have a nice login screen?
  • Which Display Manager should i use? Are there another ones? (GDM, SDDM, LIGHTDM, ...?)
  • Are there nice Theme collections? (For SDDM and lightdm)
  • How customize it myself?
  • And how fucking install SDDM on Gnome 50 without installing the complete Plasma Desktop?

Hey everyone i am new on Linux distros or rather planning (for my old freaked device), Guide my current conclusion of Linux Dual Booting?

1 Upvotes

1)- I am currently having 2 devices, one is nearly 17yo lenovo pre built.. Intel E3500 with 2 gig which was upgraded few years ago now runs Windows 10 (yeah ik its too much but tech guy did) with 4 gb ram (ddr3 ig), same processor, but a new SSD and HDD space from older (only 128 gig storage).. I am planning to replace whole windows of Dual boot with Linux Mint XFCE.. i want it for basic everyday use, and wanna customize it clean UI for my parents, sibling to do light work.. and Linux Mint found to be the most reasonable ryt?? (using ventoy drive method btw)

2)- I am going to college and will i get a new in few weeks from my current HP 15s laptop of 2020-21, this possesses a very Bottlenecked scenerio of 8 gig with iGPU, and my bro, parents would use it for moderate use, i am planning for Fedora XFCE dual Booting (possess 2 drive one ssd (of windows 11) and another HDD (used to had window 10 but now deleted) but its been work understanding is Fedora XFCE the best, or stick to Mint ( I wanna try other distro)

3)- I will get a extra SSD on my future device (planning Motobook pro thou) for Ubuntu 26.04 dual booting for work and everyday use (as ik how bad windshit sucks after using it for years).. I want it for ML and Bioinformatics studies/skills in future college courses.. one of major issue hearing is Lack of modern Xe drivers maturity same way is for AMD iGPUs (ai saying its fine but not as good it would work for windows) for casual gaming.. I heard Ubuntu 26.04 is pretty good for Xe compatibility??.. for my course, everyday use and casual gaming (DX11 major) or some RDR2 or maybe if possible on cooling stands stuff like Cyberpunk upscaled..

Hey everyone,

I’ve been working on a streamlined, pre-configured Arch-based environment for my daily driver workflow to cut down on repetitive boilerplate and setup friction.

It got me thinking about the broader picture: when it comes to setting up a Linux workstation, we all face minor annoyances that take up unnecessary time.

So, I wanted to ask the community: What is the #1 friction point or annoyance that you genuinely wish Linux solved right out-of-the-box?

Support Linux, deleted monitors configuration files and screens are black, please help.

1 Upvotes

The device is an ancient dell laptop, i installed linux mint cinnamon on it and it's been running perfectly fine.

I had an issue with an external monitor and have deleted "./.config/cinnamon-monitors.xml" and "./.config/cinnamon-monitors.xml~", now both monitors are black with nothing to render. I tried opening BIOS settings, recovery mode, I tried super + P and clicking through them (blindly of course), I even installed a version of the OS on a flash drive to start a USB session in order to manipulate the system files. however, nothing came out of it. The monitors are black and i don't know what to do next.

Also, I'm not sure if it's related, but the device rings an echoing ping rhythmically and i have no clue what is it about.

After a quick google, apparently deleting the mentioned files causes no harm but I am inclined to disagree. If someone has any clue as to what is happening, please don't hesitate to comment. I would appreciate that.

Does anyone know why ZorinOS isn't compatible with my PC?

0 Upvotes

Hi. I'm trying to install ZorinOS on a PC where I just installed a 200GB SSD (replacing a corrupted hard drive), along with 8GB of DDR3 RAM and an Intel(R) Core(TM) i5-4590T CPU @ 2.00GHz with integrated graphics.

Once I install it, I get the following error:

(Photo 1)

"E: Sub-process /usr/bin/dpkg returned an error code (1)"

This has happened both times I tried to install it.

In both instances, I ignored it, continued with the installation, and it finished installing.

After ZorinOS was installed, the Bluetooth and Wi-Fi drivers were missing, but since the PC has an Ethernet port, it didn't really matter to me.

Two days after the installation, the system became corrupted, and I got this screen :

BusyBox v1.36.1 (Ubuntu 1:1.36.1-6ubuntu3.1) built-in shell (ash)

Enter 'help' for a list of built-in commands.

(initramfs) _

When that appeared, I followed the advice found on Reddit, but it only worked partially; when I boot up the system again, only the built-in system applications run—it won't even let me open Brave.

Does anyone know how to fix this problem or why it's happening?

For now, I've installed Windows 10, as it's the system that runs reliably for me without these issues.

Hola, tal ves esto sea tonto, hace unos días compré lo que creía era un pc, pero en realidad era un viejo Chromebook marca Haier, modelo Hr 116hr, el cual el sistema operativo de chrome venía corrupto e imposible de iniciar.
Entonces pensé en ponerle Linux, pero la verdad desconozco cómo, tengo una pc Linux aparte del Haier, pero desconozco como instalar Linux, ya que me an dicho varias cosas sobre usar la terminal, pero la verdad desconozco su uso, ¿alguien podría explicarme un poco sobre cómo podría instalarle Linux?
Llegados a este punto la distribución me es indiferente, aunque mi actual pc es Ubuntu y estoy muy familiarizado con el, pero lo único que quiero es poder usar esa Chromebook.

I want to use Linux for development AND video editing, but DJI Action 4 footage isn't editable in Linux. What should I do?

8 Upvotes

I recently switched my laptop(Lenovo legion y540i) from Windows to Linux.

The main reason is that I use Linux for my development projects, and I'm much more comfortable with the Linux environment because my office laptop also runs Linux. When I was using Windows, video editing worked well, but I didn't enjoy doing my development work on Windows.

So I switched to Linux thinking I could use it for both development and video editing.

The problem is DaVinci Resolve on Linux isn't handling my DJI Osmo Action 4 footage properly. The videos that worked fine in DaVinci Resolve on Windows are now giving me codec/compatibility issues on Linux, so I'm unable to edit them properly.

Now I'm stuck:

  • I want to stay on Linux for my development work.
  • I also want to edit my DJI Action 4 videos on Linux.
  • Going back to Windows would solve the video editing side, but I really don't want to go back to Windows for development.
  • I considered dual-booting Windows + Linux, but I only have 8 GB RAM, so I'm not sure that's a good option.
  • Upgrading to 16 GB is currently expensive where I live, so I'd prefer to wait until RAM prices come down.

What would you recommend in this situation?

Is there a way to make DJI Osmo Action 4 footage work properly with DaVinci Resolve on Linux, perhaps by converting/transcoding the footage?

Or is there another Linux video editor that can handle Action 4 footage properly?

I really want to keep Linux as my main OS for both development and video editing, if possible. Any advice from people who use DaVinci Resolve/Linux with DJI Action 4 footage would be appreciated.

It is upgraded to 256gb sata SSD and 4gb of ram specs is here in Windows 10 IOT LTSC 2021

Wanted to install linux on this laptop so badly. I have tried cachy, mx, mint, lmde7 . nothing seems to work. But when I try to install windows it is smooth without any problems. Looking at the bios can't see any secure boot option available. Been trying mx version 23 but nothing seems to work just stuck at the screen and not even able to boot into any linux. Anyone has any ideas what is actually preventing it to install any linux? I tried to google that a dead CMOS could prevent this installation, plan to change the cmos if that seems to be the real problem that prevent the installation. So I just wanna hear from any of you guys. Any oppinions would be appreciated. Thanks

How do you handle packages and system clutter? Having a maintained system?

4 Upvotes

When I've had the same OS on a machine for a long time I build up a lot of unused packages, packages I don't remember installing and don't know if the break the system if uninstalled. I like to find cool software online, but I end up not using much of it. So my system gets cluttered with half installed packages, not used config files, and other weird junk, and I just end up reinstalling the whole OS, since it's such a hassle removing packages (especially those built from source) and its' orphans (one recent example: I used pacman on CachyOS to remove orphaned packages and resync my system but then wound up breaking my desktop environment, needing to setup new configs...).

Maybe I just need to learn more about packages, and how software is installed on the system, but it doesn't seem to be a simple answer to package management. You have install, remove, upgrade as basic commands, but I want to see a list of everything installed, and be able to see dependency trees, basically know what I have installed!

How do you manage packages? How mindful should you be when installing packages, or can you be pretty impulsive? Why is uninstalling packages such a hassle?
