- [Teacher] I can connect to my system using the route user … but that's not something I want to do all the time. … Root has unquestioned access to the system. … Not only do I not want to accidentally do something … without being prompted about it, … I don't want anyone from the outside to be able to have … this level of access to my computer either. … To increase security we'll set up a less privileged account … and disable remote access by the root user. … If we do need to use root's power, … we'll connect with that unprivileged user … and elevate our privileges only when needed. … I'll connect to our server using … the root user for one last time. … With ssh root @ the IP address of my server. … First I'll create a user. … I'll go over this process in a little bit … more depth later on when I talk about users and groups. … But for now, I'll type adduser and provide a username. … Of course, you might want to call your user something else. … This will create a user for me, … and its created a home folder for me as well. …
