How To install and configure SSH ubuntu server 20.04 LTS

In this tutorial I’ll discuss about how to install and configuration ssh service on ubuntu server 20.04 LTS. SSH service is using for remote access connection so that you can access the server from another network or another place remotely. It can make your job easier.

Install ssh packet with openssh-server :

root@Taufik:~# apt-get install openssh-server

Configure SSH service :

root@Taufik:~# nano /etc/ssh/sshd_config

Locate the port config and then remove the hash mark (#) in from for enable the config. Default port number is 22 and you can custom these port number.

# $OpenBSD: sshd_config,v 1.103 2018/04/09 20:41:22 tj Exp $

# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options override the
# default value.

Include /etc/ssh/sshd_config.d/*.conf

 Port 22
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::

#HostKey /etc/ssh/ssh_host_rsa_key
#HostKey /etc/ssh/ssh_host_ecdsa_key
#HostKey /etc/ssh/ssh_host_ed25519_key

After that save and exit configuration. and then restart the service :

root@Taufik:~# systemctl restart ssh.service

Test access from your computer or another computer, Test ping from computer to your server first and make sure the computer can be access to your server ip.
