Making a virtual console (Linux)

I have coded a little proggie to allow me to enter a username and password then check them both before allowing me to have access to a virtual console.

Think of it as SSH. I have used BSD Sockets, XOR Encryption and have a slurry of little tricks.

Heres the problem:

Once authenticated how can I display a virtual console? Like SSH sends a console back. How could I achieve that?

Thanks

Shouldn't you have posted this in the Linux forum?

=/ Sorry man. I Just saw C++ Programming, and thought like other forums that was the deal. Didnt see those down there...
