how to setp up a ssh server using openssh with rsa public private keys (ubuntu server): first you need to install it

 sudo apt-get install openssh-server

now you need to make a public and private key

ssh-keygen -t rsa -b 4096

your keys will be at /home/me/.ssh id_rsa and id_rsa.pub (if you didn't change the name) now we should edit the config file /etc/ssh/sshd_config first change the protocol from 2, 1 to 2 only if you want you can change the port the change the AuthorizedKeyFile from $h/.ssh/authorized keys to $h/.ssh/id_rsa.pub then change the password authentication to no to make sure you are safe from brutforce attacks

Protocol 2
Port 22
AuthorizedKeysFile       $h/.ssh/id_rsa.pub 
PasswordAuthentication no

after saving it you can run it with this command

service ssh start

now you need to move the fil id_rsa to a usb drive(not safe to email it to yourself) and connect with this command

ssh -i /path/to/id_dsa me@myserver.com

if you have a windows and you want to connect to the server download putty and puttykeygen open the putty key generator click on conversions and import key the click the "save the private key button" the file that you created with the extension of .ppk is the one that you will use with putty to connect to the sever
