SSH: Gods Gift to Humanity...

SSH - SCP - SFTP

• Password vs key
• Create the key:
  

  
                  ole@gauss$ ssh-keygen
                  Generating public/private rsa key pair.
                  Enter file in which to save the key (/root/.ssh/id_rsa): /root/.ssh/id_rsa.test
                  Enter passphrase (empty for no passphrase): 
                  Enter same passphrase again: 
                  Your identification has been saved in /root/.ssh/id_rsa.test.
                  Your public key has been saved in /root/.ssh/id_rsa.test.pub.
                  The key fingerprint is:
                  SHA256:mMSAWNNZQnEGYbfW+KHDKV6e9R516TNRjSk/Nb5F7KQ root@gauss
                  The key's randomart image is:
                  +---[RSA 2048]----+

                  ole@gauss$
                       

• DO NOT CREATE KEY FOR ROOT!!! - unless you have to...
• Copy the key
• root@gauss$ ssh-copy-id -i ~/.ssh//root/.ssh/id_rsa.test user@host
