## Server
- Install Debian (debian-11.5.0-amd64-netinst.iso) on remote system
- Create user (tudattr)
- Get IP of remote system (192.168.20.11)
- Create ssh-config entry
  ```config
  Host aya01
    HostName 192.168.20.11
    Port 22
    User tudattr
    IdentityFile /mnt/veracrypt1/genesis
  ```
  - copy public key to remote system
  `ssh-copy-id -i /mnt/veracrypt1/genesis.pub aya01`
- Adjust ansible inventory
- Install sudo on remote
- add user to sudo group (with `su --login` without login the path will not be loaded correctly see [here](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=918754)) and `usermod -a -G sudo tudattr`
- set time correctly when getting the following error
```sh

     User tudattr
     IdentityFile /mnt/veracrypt1/genesis
```
- enable ssh on pi

## Mikrotik
- Create rsa-key on your device and name it mikrotik_rsa

```config
Host mikrotik
     HostName 192.168.70.1
