Re: All this to avoid installing ssh and usable command line tools
"The difference is that with a shell you have far broader access. With proper remoting, you can restrict more easily what someone can do on a remote machine. Just, proper remoting requires more effort to implement than a simple shell."
Wtf are you talking about?
I have no idea how windows implements its shell permissions but apparently it seems you need to go learn about unix's user, group and world read/write/execute permissions. Welcome to 1970.
(And thats the basic stuff, there's also access control lists, chroot jails, containers and the bells and whitsles of SE Linux).
