I use Centos$9.$ Lab $5\mathrm{.}1$

$1.$Log in to the local console on server$1.$ Make sure that server$1$ does not show a graphical

interface anymore, but just a text$-$based login prompt.

$2.$Log in from that environment and activate tty$6.$ From tty$6,$ switch back on the graphical

interface and use the correct key sequence to go to the graphical interface.

Lab $5\mathrm{.}2$

$1.$Set up SSH$-$based authentication. From server$2,$ use SSH to connect to server$1.$

$2.$Make sure that graphical applications are supported through the SSH session. Also set up key$-$

based authentication so that no password has to be entered while connecting to the remote

server.d
