-### Setup ssh key for connecting to other servers
-
-This next ssh key is generated for internal servers:
-
-```
-ssh-keygen -q -t ed25519 -N '' -f ~/.ssh/id_ed25519_mynetwork <<<y >/dev/null 2>&1
-
-# older machines might not support ed25519, then use RSA with 4096 bit key
-# ssh-keygen -q -t rsa -b 4096 -N '' -f ~/.ssh/id_rsa_mynetwork <<<y >/dev/null 2>&1
-```
-
-The public ssh key is in `~/.ssh/id_*_mynetwork.pub`.
-Copy the public key to machines which you want to access with this machine.
-Inversely, if you want other machines to ssh to this machine,
-copy their public keys to this machine.

-`sudo update-locale LC_TIME=en_DK.UTF-8`
-
-## Password Manager
-use keepass :key: (with secret file)
