To connect to a Linux OS running in VirtualBox using PuTTY, you will need to do the following:
Start the Linux OS in VirtualBox.
In VirtualBox, go to the "Settings" for the Linux OS and navigate to the "Network" tab.
Change the "Attached to" option to "Bridged Adapter".
Start PuTTY on your host machine.
In PuTTY, enter the IP address of the Linux OS in the "Host Name (or IP address)" field. The IP address can be found by running the command "ifconfig" in the Linux terminal.
Select "SSH" for the connection type.
Click "Open" to connect to the Linux OS.
A terminal window will open and prompt you for a username and password.
Once you are connected to your virtual linux machine via putty you can use it as a remote machine.
That’s it.
