Screen sharing query

[Alexander]

I’m a newbie here, would you please let me know a screen sharing software that runs on Linux.

[TNC]

Please explain "screen".

Do you mean a screen in meaning of a text based screen (for example /dev/ttyS0)

A graphical interface you already run (for example you running gnome under ubuntu and want that screen to be seen on a another computer)

A remote graphical session (you log onto your computer completely transparent from anywhere)

Or a complete graphical redirection including everything that is X (the server that brings any graphical fun up) based.

Cheers! :)
