A text with misleading title, it is neither only meant for _Advanced_
users as it assumes no previous exposure to the Unix shell, nor covers
only _Bash_, taking instead an integrative approach which reflects a

can also serve as a reference. While outdated in the sense that that
last revision is from 2014, it still covers the vast majority of
interactions one has with a GNU\Linux system through the shell.

# SSH Session From a Terminal
# Connect to a host, on a particular port with a particular address
# with a given username.
# If password-based authentication is enabled, you will be presented
# with a password prompt.
ssh -p 8022 tk2020@
# A much more secure approach (sometimes the only option, if other
# forms of authentication are disabled on the server) is use key based
# authentication.
# SSH Session From a Terminal: Key Based Authentication
# First, generate the key if you do not have it (if you do, it will be
# present in ~/.ssh directory). You will be presented by a series of
# dialogues for which defaults are ok. Please choose a strong
# passphrase when prompted.
ssh-keygen -b 4096
# Next, add the key to your ssh-agent. This prevents you from having
# to type the passphrase each time you want to log in. Accept the
# default suggestion.
# No ssh agent present? Then run
# ssh-agent > agent.env.out
# source agent.env.out
# Try to connect again.
ssh -p 8022 tk2020@
