Is it possible to run Linux cli tools on the EX2 Ultra?

I just got the EX2 Ultra last week, and was looking around at it. My main use is for media, of which I DL a lot of youtube videos. Is there anyway I could get either youtube-dl, or aria2 to run on system, so that it can download right to the right folders, instead of my current DL on a computer then push to a ftp folder?

IE: so I could either ssh in, or use a web gui (for Aria2), and get whatever video I want DLing while I am at work?
