sorry about that, I was implementing the shell and a responce, mozilla
crashed and google talk sent a blank message. the app i'm running

i modified the classroom_pc function, now i'm getting an error

the application runs in a curses environment.

def classroom_pc( host, command )
Net::SSH.start( host, Username, Password) do |session|
shell = session.shell.sync
puts "Opened Connection to #{host}"
shell.send_command( "export TERM=linux" )
p shell.send_command( "#{command}")
shell.exit

end
that seems to have done it, it doesnt display the ncurses info but i
can live with that for now.
