I'm a newbie of Debian, I have installed debian with gnome on one of my machine (call it A), and i want to remote login it from another machine (call it B) who is also installed with debian & gnome, and i also want to remote login machine A from another machine (call it C) who is installed with Windows 8.
What packages should i install on each machine - A,B,C - so that i can remote login into the gnome desktop of A from B and C?
