Install SEP on Linux for trial

Hello,

I want to install a SEP client in a Linux PC (The Linux is Debian with kernel 3.4.x) for trial, so I downloaded the SEP 12.1.6 (12.1 RU6 MP4) for trial. But after installation, I can only find Windows and MAC in client install package.

Where can I download the Linux install package? Or we need to pay before we can try the Linux client?

Thanks!

Danny
