display remote commands

is there a way to display the commands the the remote user is typing -I would like to know a way by which i can log onto a remote system and type commands as the user watched on the console - I know about vnc but that is not what i am looking for -or is it rexec ?

In a word "screen"

man screen yields nothing - but just saw Gnu screen
running Solaris 10 x86 -Downloading to install and experiment

Thanxs

you can use "dtrace" scripts to watch keystrokes of all users....
