X11 har en mulighed for at f\u00e5 adgang til de programmer som kr\u00e6ver en GUI for at k\u00f8re over SSH<\/a>. Det vil sige at du har mulighed for at k\u00f8re GUI programmer remote hvor sk\u00e6rm output vil blive vist p\u00e5 din lokale linux pc.<\/p>\n

SSH har en mulighed for at forward X11 programmer gemen ssh tunnelen tilbage til din pc.\u00a0 Det eneste som kr\u00e6ves installeret er xauth, for at f\u00e5 det til at virke.<\/p>\n

$ sudo apt install xauth<\/pre>\n
For at enable X11 forward skal du rette i sshd konfig filen p\u00e5 maskinen du skal have adgang til. Login med ssh og check at X11Forwarrding yes<\/strong> er i konfig filen.<\/p>\n
Derefter skal du genstarte ssh med denne kommando.<\/p>\n
P\u00e5 Ubuntu.\n$ sudo service ssh restart<\/pre>\n
P\u00e5 Debian.\n$ sudo service sshd restart<\/pre>\n
Du er nu klar til at login med X11Forwarding. Det g\u00f8r du med en parametre til ssh kommandoen -X<\/p>\n
$ ssh -X 192.168.0.23<\/pre>\n
Du kan nu starte programmer remove fra serveren. Alt dette er globalt p\u00e5 maskinen. Hvis du vil have at det er pr bruger som nok er mere sikkert, skal du i stedet oprette\/rette i din maskinens lokale ssh konfig fil.<\/p>\n
$ vi $HOME\/.ssh\/config<\/pre>\n
Som f\u00f8r inds\u00e6t ForwardX11 yes<\/strong> i filen og gem den igen.<\/p>\n
Du har nu enabled X11 forward men kun pr bruger basic.<\/p>\n
$ ssh -X bruger@192.168.0.23<\/pre>\n
