Linux client

I have 12.1.5 and was wanting to test the linux client. Read another post that said there should be a savlinux directory in my download (which there isn't). Yet another post said I can download the client from the software downloads portal where I got 12.1.5 (its not listed). Is there still a linux client for 12.1.5 small bix edition, and if so how do I get it keeping in mind I have already searched and tried what was suggested.

Thanks
