Dear Mark This is the exact scenario of my machine. i am running the cent os under my virtual box and i have made a network bridge to that VBOX so from my machine i connect to the VBOX using the Xshell. and by the way i am new to linux and this is my test machine so that i do some testing. this is the F reason i am using the root user. what ever os is it i dont think logging in as root user will crash the system. regarding the halt command i used it to check what this command will do and this one i have done from the F manual only. but now my VBOX machine crashed.
