SSH

Connecting SSH ssh username@local/publicIP

Hosting SSH
- Creating a key ssh-keygen -t rsa -b 4096 -C "commentExample"
- Copying the content of the id_rsa.pub generated before and adding it to the ~/.ssh/authorized_keys file on the server
Disable Password Authentication on the Remote Server (Optional but recommended)
- SSH into the server:
```
ssh user@remote_host
```
- Open the SSH configuration file in an editor (e.g., nano):
```
sudo nano /etc/ssh/sshd_config
```
- Ensure the following lines are set (you might need to uncomment them by removing the #):
```
PasswordAuthentication no
UsePAM no
```
  Save and exit the editor (in nano, press Ctrl + X, then Y to confirm, and Enter to save).
- Restart SSH service to apply the changes:
```
sudo systemctl restart sshd
```
This will prevent users from logging in via passwords, forcing them to use SSH keys instead.
