Tutorial

SSH Keys and VPN

Enable SSH

Install: sudo dnf install -y openssh-server
Start service at boot: sudo systemctl enable sshd.service
Start service: sudo systemctl start sshd.service
To test, run: ssh localhost -l <username>
(Optional) Change default port:
- Open sshd_config: sudo vi /etc/ssh/sshd_config
- Find a line: Port 22 (or #Port 22)
- Change it to some other port number (choose port number between 1024 and 65535): Port 2222 (make sure to remove commenting #).
- Save the file.
- Update iptables and firewall to allow traffic:
```
sudo /sbin/iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 2222 -j ACCEPT
sudo firewall-cmd --permanent --zone=public --add-port=2222/tcp
sudo firewall-cmd --reload
```
- Restart sshd service: sudo systemctl restart sshd.service
- Verify that your new port is open: netstat -tulpn | grep 2222

Generate SSH Public Private Key Pairs

Run ssh-keygen and answer the prompts.
Verify you have the files: ls ~/.ssh
Start ssh-agent: eval `ssh-agent`
Add private key to ssh-agent: ssh-add ~/.ssh/id_rsa
You can now use the content of ~/.ssh/id_rsa.pub as your public key.
For example, add the content of ~/.ssh/id_rsa.pub as your bitbucket.org or github.com ssh key.
Note: Fedora33+ drropped SHA1 support. You have to update configurations for legacy hosts such as bitbucket.
- Create a file ~/.ssh/config with following content:
```
Host bitbucket.org
    PubkeyAcceptedKeyTypes +ssh-rsa
```
- Change permission: chmod 600 ~/.ssh/config
To verify: ssh -T [email protected] or, ssh -T [email protected]

Setup GPG Keys

GPG is often used for signing your release artifacts, commits for GitHub etc. Follow these instructions
Generating a new GPG key
Adding a new GPG key to your GitHub account
Telling Git about your signing key

Development Tools

Visual Studio Code

Run following commands

sudo rpm --import https://packages.microsoft.com/keys/microsoft.asc
sudo sh -c 'echo -e "[code]\nname=Visual Studio Code\nbaseurl=https://packages.microsoft.com/yumrepos/vscode\nenabled=1\ngpgcheck=1\ngpgkey=https://packages.microsoft.com/keys/microsoft.asc" > /etc/yum.repos.d/vscode.repo'
sudo dnf check-update
sudo dnf install code

Source

JetBrains Toolbox

Download tar.gz archive from Toolbox App page.
Extract and run JetBrains Toolbox binary executable file by double clicking.
This should install and run the toolbox. You can install your favorite JetBrains IDEs (PyCharm Community, IntelliJ IDEA Community, Android Studio, etc) from the toolbox, it will keep them updated too.
You can remove downloaded and extracted files after installation.

Postman

You can install Postman via snap. Visit https://snapcraft.io/postman. If you do not like snap, you can manually install Postman using the following steps:

Download the .tar.gz file from https://www.postman.com/downloads/.
Extract the archive file: sudo tar xvzf Postman-linux-x64-8.10.0.tar.gz -C /opt
Create symlink: sudo ln -s /opt/Postman/app/Postman /usr/local/bin/postman

Open a file ~/.local/share/applications/postman.desktop and add the following content

[Desktop Entry]
Name=Postman
GenericName=API Client
X-GNOME-FullName=Postman API Client
Comment=Make and view REST API calls and responses
Keywords=api;
Exec=/opt/Postman/app/Postman
Terminal=false
Type=Application
Icon=/opt/Postman/app/resources/app/assets/icon.png
Categories=Development;Utilities;

Hide postman directory from your home:
```
echo "Postman" >> .hidden
```

Languages

C/C++

Comes with gcc 11.
If you use g++ command, you can install sudo dnf install gcc-g++

Python

Fedora 36 comes with Python 3.10, follow this for older versions of Python 3.
Install python headers and static libraries: sudo dnf install python3-devel
Update pip: python -m pip install --user --upgrade pip
Install python libraries like cookiecutter, tox, pytest, etc using pip.

Java

Visit Oracle's site to download and install Oracle's Java SDKs. Be careful about licensing if you are using a later version than Java 8. It is recommanded to use JDK libraries locally to avoid system-wide mess with update-alternatives command.

Go

Download linux archive and run tar -C /usr/local -xzf go$VERSION.$OS-$ARCH.tar.gz
Upate $PATH variable at the end of your ~/.bashrc file:
```
export PATH=$PATH:/usr/local/go/bin
```
Source bashrc file: source ~/.bashrc

NVM and NodeJS

Use NVM (Node Version Manager) to install and manage multiple version of NodeJS and npm following this guide
Installation:
- curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.35.1/install.sh | bash
- source ~/.bashrc or exec bash
Run nvm ls-remote to list down all available node versions
Install your required version using nvm. Example: nvm install 16.17.1
Actiate a specific version using nvm. Example: nvm use 16.17.1

Apache Server (Apache httpd)

Install Apache HTTP server following this guide
Test if the HTTP server is running: sudo systemctl status httpd

Docker

Podman comes with Fedora/CentOS/RHEL systems. Podman should be able to work with your dockerfiles, and in many cases, a more flexible option. Anyway, you can install docker in Fedora 34/35/36. Note: For older versions of Fedora, Docker can only be installed after downgrading to cgroup v1.

Install the dnf-plugins-core package (which provides the commands to manage your DNF repositories) and set up the repository.

sudo dnf -y install dnf-plugins-core
sudo dnf config-manager \
   --add-repo \
   https://download.docker.com/linux/fedora/docker-ce.repo

Install the latest version of Docker Engine, containerd, and Docker Compose or go to the next step to install a specific version:
```
sudo dnf install docker-ce docker-ce-cli containerd.io docker-compose-plugin
```

Start docker service and check status

sudo systemctl start docker
sudo systemctl status docker

Add yourself to docker usergroup to access without sudo
```
sudo usermod -aG docker $(whoami) && newgrp docker
```

Update firewall

sudo firewall-cmd --permanent --zone=trusted --add-interface=docker0 && sudo firewall-cmd --reload
sudo firewall-cmd --permanent --zone=FedoraWorkstation --add-masquerade

Verify that Docker Engine is installed correctly by running the hello-world image.
```
sudo docker run hello-world
```

Docker and Sudoer (a.k.a Why Podman is better?)

Why can't we use docker commands without sudo in Fedora/RHEL/CentOS by default?

Install Docker Desktop

Docker Desktop is an easy to use app to track your docker images and maintain image lifecycle.

Set up repository

sudo dnf -y install dnf-plugins-core
sudo dnf config-manager --add-repo https://download.docker.com/linux/fedora/docker-ce.repo

Download rpm package using wget or from here

wget https://desktop.docker.com/linux/main/amd64/docker-desktop-4.13.0-x86_64.rpm

Install RPM Package

sudo dnf install -y docker-desktop-4.13.0-x86_64.rpm

Search Docker Desktop on the Applications menu and open it. This launches the whale menu icon and opens the Docker Dashboard, reporting the status of Docker Desktop. Alternatively, open a terminal and run:
```
systemctl --user start docker-desktop
```
