VNC i pokretanje GUI programa kao root

[Marel]

Instalirao sam vnc4server, a na drugoj mašini xvnc4viewer i sada sa nje mogu da otvorim remote desktop na prvoj mašini. Ali kada iskoristim su da radim kao root, ne mogu da pustim ni jedan GUI program, a poruka je

[code]# gedit
No protocol specified
cannot open display:
Run ‘gedit –help’ to see a full list of available command line options.[/code]

“Izvezao” sam DISPLAY=”:1.0″.

[code]# ps -Af | grep Xvnc4

Pa ako neko ima ideju…

[RiSK]

Ko ima pristup tim masinama?

Ako samo ti, onda pozovi kao user koji je pokrenuo X server
[code]xhost +[/code]
Pre nego sto pokrenes GUI aplikaciju kao super user.
Kad zavrsis rad mozes jedno [code]xhost -[/code] da vratis na staro.

Ako je u pitanju sistem na koji ima pristup vise ljudi, ne otvaraj ovako privilegije. Pogledaj man strane za xauth i xhost pa namesti sta ti treba 😉

[Marel]

Da Risk, to je rešenje O0 . Prevideo sam da je to zaseban X server, pa treba da se ponovo podesi xhost.

Ali imam još jedan problem. Ako je korisnik prijavljen na normalan X server, ne mogu da se prijavim preko mreže na istog korisnika, tj. ne može da se podigne Gnome na obe sesije. KDE radi, ali meni je Gnome dobro podešen, pa bih ako je moguće da osposobim njega za VNC. Sa tightvnc-om je koliko se sećam to radilo bez problema, ali sam morao da stavim vnc4, jer sam imao problema sa tastaturom, tj tasteri su skroz ispretumbani, a nije zanemarljiv ni dobitak u brzini preko spore konekcije (Internet). Tako da ne bi bilo loše neka mala pomoć i oko toga.

Pozdrav.
