| # Script for Ubuntu: Nvidia Multi-GPU Installation and Testing (Adaptable for other distros) | |
| # Step 0: Clean Nvidia Installation | |
| # If you need to completely remove a previous Nvidia installation, use these commands. | |
| # This ensures that you start with a clean slate for a new installation. | |
| sudo apt-get --purge remove "*nvidia*" | |
| sudo apt-get --purge remove "*cuda*" "*cudnn*" "*cublas*" "*cufft*" "*cufile*" "*curand*" "*cusolver*" "*cusparse*" "*gds-tools*" "*npp*" "*nvjpeg*" "nsight*" "*nvvm*" "*libnccl*" | |
| # Verify that the removal is complete by checking if any Nvidia, CUDA, or cuDNN packages are still installed. | |
| apt list --installed | grep cuda |
| #!/bin/busybox sh | |
| # 1) Download a prebuilt BusyBox binary here: | |
| # https://busybox.net/downloads/binaries/ | |
| # | |
| # 2) Prepare your kernel | |
| # cp /boot/vmlinuz vmlinuz | |
| # | |
| # 3) Copy the files | |
| # install -Dm0755 busybox-x86_64 initramfs/bin/busybox |

Captive portals can be a pain. Here's an opinionated and no-doubt entirely imperfect guide to setting one up for a WiFi access point on Ubuntu (tested on 20+), utilising Network Manager, DNSMasq, HA Proxy and (optionally) Let's Encrypt for a secure, locally hosted landing page.
_Note: This setup was originally designed for an offline WLAN, providing access to a small number of locally hosted domains ... think the WiFi media portal on a flight or boat. If you are looking to provide internet access behind a captive portal then this guide won't get you all the way there. That said, many routers have this capability built in, as do any number of open source router firmware solutions. So you probably don't need to roll your own. If you'd like to try anyway, Ha Proxy Stick Tables would probably come in handy. Very happy to update the guide with any p
Please comment below if you have an update, e.g., with another networking-related dataset.

On March 29th, 2024, a backdoor was discovered in xz-utils, a suite of software that gives developers lossless compression. This package is commonly used for compressing release tarballs, software packages, kernel images, and initramfs images. It is very widely distributed, statistically your average Linux or macOS system will have it installed for
