Install ssh di Ubuntu 20.04

Anggap saja kita baru pertama kali menginstall sistem operasi linux dan belum melakukan konfigurasi apa-apa setelah berhasil melakukan install. SSH (Secure Shell) sendiri adalah protocol yang digunakan untuk melakukan remote server yang menggunakan ip address dan aplikasi ssh sebagai akses masuknya. Untuk melakukan instalasi SSH dapat melakukan perintah berikut:

Install

$sudo apt-get update
$sudo apt-get install openssh-server

$ sudo apt-get install openssh-server
