===== SSH-Copy-ID =====
The Linux Tool ''SSH-Copy-ID'' allows a password-less authentication for a SSH-connection.

==== Installation ====

It's part of the package ''openssh-client'': 
<code bash>sudo apt install openssh-client</code>

==== Setup ====
Firstly generate SSH-Keys on the machine that should later connect to another machine:
<code bash>ssh-keygen</code>
All prompts can be skipped!

Finally copy the created key to the target-machine (the machine, to which a password-less SSH-connection should later be established):
<code bash>ssh-copy-id -i /path/to/public-keys <username>@<hostname-targetserver/ip></code>

Example:
<code bash>ssh-copy-id -i /home/user/.ssh/id_rsa.pub root@10.0.1.230</code>
