On tar files, the flash player is a tar.gz To extract it, if you have the icon on the desktop, or in konqueror, just right click on the icon and select extract.

Note that when you run the flash- installer, it will ask you where the plugin folder of your browser is. Usually it wil be in /usr/lib. Firefox's is /usr/lib/firefox/plugin but I am not sure where the Opera one is. You can also not run the installer and manually install the plugin -- after extracting the tar.gz, you will have a folder with a few files (For example the readme will give you instructions how to run the installer). But the 2 important files are the .xpt and .so. These need to be copied to the plugin folders of your browsers.

For deb files. just click on the icon and the package manager will launch.


By the way, since you got your Knoppix running on an Xbox, could you share your experience of how this was done? I think some forum users here would be interested.
