It's still Windows-only, however it works great in Linux using WINE.? If you install a WINE version that's 9.0 or newer, then nothing extra needs to be done to get VARA to run; just download VARA and install it like normal.?? I'm very happy with it; been using it for quite a while 24/7 on my Linux machine as a packet node port.? The only thing that doesn't work when using it in WINE is VARA's CPU usage meter, but it's not necessary anyway.
