SSH

basic

• /etc/ssh/ssh_config - config location (client)
• /etc/ssh/sshd_config - config location (server)

It is always smart to disable root login! --> uncomment PermitRootLogin no

Enable encryption

• ssh-keygen -t rsa - generate private and public key
• ssh-copy-id <server-ip> - copy ssh identity to server

--> uncomment PasswordAuthentication no (on server) Warning store private key on a secure location, if you lose it, you will lose connection to a server!

FAIL2BAN

• install a basic ubuntu vm and watch from 4:20 in video he he u get it, but it is actually there

SCP

• scp <filename> <user@server_ip:/destination_folder> - copy file to server
