hello everyone in this video we are going to see what are the most important things that we need to do after installing Linux on our computers so first of all we need to update our operating system to do so we need to check to see if we have internet connectivity we use the Ping command for this and we can see that we are connected to Internet the command that we're going to use is sudu apt update it's going to ask for the password we enter it and we let it go for you it might take a little bit longer if you have old packages but what this command does the sudu apt update is a Linux system administration command that updates the list of available packages and their versions in the systems package index this command is made up of three parts sudu apt and update sudu is short for super user do this grants the user that we are logged in as root privileges AP is the package manager and update tracks changes to each package when a new version is released after our packages are updated we need to to upgrade all of the software that have been updated so this second command has three parts also sudu app upgrade is a command that downloads and installs updates for outdated packages and dependencies of Linux system before running sudu app upgrade it is recommended to run sudu appt update to ensure the system has the latest information on available packages and their versions this action is going to take some time depending on the speed of your internet and the packages that your computer needs to update [Music] a [Music] m [Music] okay guys as we can see see the update is over as I said before it will take some amount of time depending on the speed of your internet the packages you are going to update and the performance of the VM or the computer that you are running your Linux on the next thing that we're going to do is installing apps that we need to do this we simply write sudu apt install and the name of the application that we want to use in this case I'm writing Git it again will ask for a password I will enter it yes and it will install G on this computer you can go ahead and install any application that you want it's the same process sudu app install name of the application for example this says that it's already installed on my computer but any other application will simply do so the last thing that we're going to do is install and configure SSH weuse hsh to connect and control our Cali Linux or any other Linux distribution for that matter through other terminals without connecting directly to the computer or VM itself to do this we run sudu appt install as open Ash server open SS server is the server that is usually installed on most of the systems by default but here as you can see it's not installed so we're going to install it after it's being installed we need to make it auto start start on boot so we're going to run the command sudu system CTL enable SSH then we need to start at I can check the status um as you can see it's enabled and active and running enable will make it reload automatically on the next reboot that's it let's see if we can connect to it through a hsh client so this is our IP address 192 168 64 4132 and right now we are going to try to connect to it through a s client it's going to ask for the user K user password is and that's it guys so thank you for watching these steps will help you get the most out of your Cal Linux installation you can also configure the environment create a regular user account configure your firewall and so on based on your performance if you found this video helpful don't forget to like share and subscribe to our channel for more tutorials thank you for watching
