Installing Kodi Ubuntu 14.04

Refer: http://ubuntuhandbook.org/index.php/2016/02/kodi-16-released-how-to-install-it-via-ppa/

$ sudo add-apt-repository ppa:team-xbmc/ppa
$ sudo apt-get update
$ sudo apt-get install kodi

This probably won't be needed
sudo apt-get install --install-suggests kodi

Helpful Hint
Kodi the \ is the shortcut key to toggle between fullscreen and window

Refer: http://askubuntu.com/questions/849396/uninstall-kodi-on-ubuntu-14

If you need to remove and purge an application and finally removing/purging also the application configurations files, do so by using the following commands:

$ sudo apt-get update
$ sudo apt-get remove kodi*
$ sudo apt-get purge kodi*

Then remove the settings folder to remove all settings and library data. This will not delete any videos or music, but just the settings and library data itself:

$ rm -r ~/.kodi/
or
$ rm -r ~/.xbmc/
for older versions before 14.0

Remote Execution Commands

Here are some of the tools I have used in the pass to do various things. If I have to use something today then that would be SSH and Ansible for any mass operations

For all small jobs I generally go with SSH safe and secure.
Here are some of the examples of how you can put SSH to use. Make sure you setup credential keys for ease.

www.cyberciti.biz/faq/unix-linux-execute-command-using-ssh

www.cyberciti.biz/faq/linux-unix-osx-bsd-ssh-run-command-on-remote-machine-server

Following is the tool that allows you execute commands on multiple hosts. This is Python based.

Ansible:

On Windows machine I used PowerShell. I find powershell too complicated and cryptic

Enable SSH in Ubuntu 14.04 Trusty Tahr and 18.04

For 18.04 you will need to install through Synaptic

This simple tutorial is going to show you how to enable Secure Shell (SSH) service in Ubuntu 14.04 Trusty Tahr.

Secure Shell (SSH) is a cryptographic network protocol for secure data communication, remote command-line login, remote command execution, and other secure network services between two networked computers.

SSH is not enabled by default in Ubuntu, but you can easily enable this service via OpenSSH, a free version of the SSH connectivity tools developed by the OpenBSD Project.

To do so, run the command below in terminal:

sudo apt-get install openssh-server

Remove login with root password

$ sudo nano /etc/ssh/sshd_config

# Authentication:
LoginGraceTime 120
PermitRootLogin no

Or install the openssh-server package via Ubuntu Software Center if you’re on Desktop edition:

install ssh server Ubuntu 14.04

Once installed, you can change the port, disable root login and do other changes by editing the config file:

sudo gedit /etc/ssh/sshd_config

Finally restart the ssh server to take place:

sudo /etc/init.d/ssh restart
