Have you considered creating a chroot environment for this user. This would do all you want plus some more.

If you want chroot ssh user to there home directory alone.Try these

thanks for your replys well im nob... i didnt know about chroot but if somebody can helpme with a good how to make something like that will be greate dont know if the chroot its the solution but im reading about that but i think it will take me more time that i though

I would go for chroot, it allows you to only allow access to the bare essentials and nothing else. It does take some time to set up, namely because login errors are not very verbose, so it can take some trial and error until you copy over everything required for a successfully chroot login, but it's worth it IMO. Once you get it set up for one user, you can set it up for any number of users with relative ease.

Here's, what looks like the simplest and fastest way to start:

Since you'll be using a desktop environment, remember to add it's files together with X's files to the APPS lines of the script.

Hope this get's you going.
