A set of shell scripts to automate the setup of an Ubuntu 20.04.0x and above server, by:

1. Updating and upgrading the fresh install;
2. changing the default user's password;
3. changing the default user's name;
4. setting up ssh keys for remote connection;
5. configuring the ssh server;
6. configuring ufw;
7. configuring fail2ban;
8. configuring the timezone;
9. configuring git;
10. installing docker; and
11. setting some environment variables for docker usage.

Clone the repository, and submodules, then switch to the repository directory with:

git clone --recursive https://github.com/papalozarou/linux-setup.git && \
cd ~/linux-setup

Run the first script:

sudo ./01-initialise-setup.sh

Once completed, run subsequent scripts following instructions and prompts.

When all scripts have been executed, it's safe to delete the repo with:

sudo rm -R ~/linux-setup

This leaves the .config/linux-setup directory in place for reference.

Script change-username.sh kills all processes and requires logging in with a temporary user which is set up as part of the script.

The scripts are not particularly robust in terms of error handling. Soz like.

• Fix docker validation
• Move all service installs to using installRemovePackage function
• Add timezone and NTP setup
• Robust error handling
