There's a flash player available for Linux at http://www.adobe.com/shockwave/download/alternates/
If you want a copy of Shockwave running in Linux, I suggest you install it using Codeweaver's Crossover Office (a demo is available at http://www.codeweavers.com/products/cxoffice/
Please note that the full version is NOT free. Crossover also offers you an option to install Adobe Flash itself (an environment to develop flash files), in case you meant that in your previous post instead of the 'Flash Player'.
Because crossover uses Wine to install all of their applications, you might also want to google for a tutorial on installing Shockwave/Flash using Wine (which is totally free and can be found at http://www.winehq.com/
Edit: In case you never heard of cxoffice, it's a program which has some nice automated features available for you to install Windows programs on your Linux dist. If you really want to install Shockwave, you have to rely on such kind of software since there's no version of Shockwave available for Linux, neither a version of Flash.
