Addendum Notes on “Learn Linux in 5 Days and Level Up Your Career” by Jason Cannon on Udemy


Connecting to a Linux Virtual Machine Over the Network

1. Stop virtual machine.
2. Highlight virtual machine and click settings in VirtualBox.
3. Nightwork adaptor needs to be Attached to Bridged Adapter, in case you are working on a home network.
4. check if a SSH Server is installed and running. To check this type ps -ef | grep sshd. Check if it is installed dpkg -l | grep ssh-server. Or rpm -qa | grep ssh-server on a RedHat distribution.

On an Ubuntu system:
1. sudo apt-get update
2. sudo apt-get install openssh-server openssh-client
3. sudo service ssh start – To start running sshd.

On a RedHat based system:
1. sudo yum install openssh-server openssh-client
2. sudo service sshd start – To start running sshd.

Next, find the IP address:
/sbin/ip addr
Look at the inet line, could look like this: inet brd scope global eth1

Now we can connect to the Virtual Machine with the IP address:
ssh adminuser@
exit – To exit out of the virtual machine.
Use of putty on Windows machine:
Enter the IP address and click OPEN in the PuTTY graphical interface.

Download the wordpress.tar.gz file.

tar zxvf wordpress.tar.gz – Extract contents of that file.
cp wp-config-sample.php wp-config.php – Copy wp-config-sample.php.
