Does RADIUS 2.0 run on Linux for Alpha?
If it is not on the list of supported platforms it is not available in binary form. The source compiles on Linux for X86 and is 64-bit clean (for Alpha OSF/1) so we would expect it to be easy to compile on Linux for Alpha. If you try that and it works let radoc@livingston.com know what release you used and we will update this answer.
