# AutoSSH

## don't use a password
Generate a passphraseless SSH key and push it to your VM.

If you already have an SSH key, you can skip this step… Just hit Enter for the key and both passphrases:

$ ssh-keygen -t rsa -b 2048
Generating public/private rsa key pair.
Enter file in which to save the key (/home/username/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/username/.ssh/id_rsa.
Your public key has been saved in /home/username/.ssh/id_rsa.pub.

## Copy your keys to the target server:

scp ~/.ssh/id_rsa.pub ItDev_Billy@192.168.1.110:/home/ItDev_Billy

## Add public key to autorized_keys

cat id_rsa.pub >> ~/.ssh/authorized_keys
.ssh/authorized_keys
to make sure we haven’t added extra keys that you weren’t expecting.

## Finally check logging in…

$ ssh id@server
