Pi Ubuntu SSH and Hostname

Posted under » Ubuntu » Raspberry Pi » AWS on 01 January 2022

For ubuntu server installation, First thing is to login. It will create a user call ubuntu. The default password is also 'ubuntu' but you will be asked to change it to a more secure password. Login as root and do apt update. Then proceed to

$ apt install openssh-server 
$ apt install net-tools

The hostname by default is ubuntu and in AWS it is usually 'ip-173-10-2-4' and you might want to customise it

$ hostnamectl set-hostname "pidua chantek" --pretty
$ hostnamectl set-hostname pidua --static
$ hostnamectl
 Static hostname: pidua
       Icon name: computer-vm
         Chassis: vm
      Machine ID: bba832ceb88846b1a9045c9f200dcc6c

Go to /etc/hosts file and make sure there is 127.0.0.1 pidua otherwise 'sudo su' will be slow.
