Jetson Nano

Operating System

The operating system is the one provided by nvidia, an ubuntu 18.04 available here: https://developer.nvidia.com/embedded/learn/get-started-jetson-nano-2gb-devkit#write

Setup

Docker

We first need to install docker and add our user to the docker group in order to not have to use sudo to run any docker command

SSH

We need to setup the SSH so that we can connect whenever we need and without password authentication, only a publickey authentication, this configuration is in the file /etc/ssh/sshd_config. We also need to enter everyone’s public keys into the ~/.ssh/authorized_keys so that everyone can access the jetson

For now, we have a big issue with SSH. The initial situation was: we could connect from a computer once and after closing the SSH connection, it would spit “connection refused” on every other try. The actual situation is the following: we can connect multiple times in a row after closing previous connections but after a while we start getting “connection refused” messages. The solution used at the moment is one provided by jetson nano users on an nvidia forum (https://forums.developer.nvidia.com/t/unable-to-ssh-into-jetson-nano-through-ethernet/72639/8) and we need to find the root cause of this issue to be able to entirely fix it.

Git / Github

We need to generate SSH keys and add the publickey to the github organization so that the jetson can clone the repositories.

Configuration

Shell

The shell used is ZSH with Oh-My-Zsh (https://ohmyz.sh/) and PowerLevel10k (https://github.com/romkatv/powerlevel10k). The whole other shell aliases and stuff like that are my personal configuration. Some aliases do not work since the programs called aren’t installed and I didn’t bother looking too much for them for now since it’s just QoL stuff and having the SSH working is more important right now.
