Ask HN: Fileshare without dropbox etc.

I often need to share files with wife at work, when she needs some help but dropbox etc is all blocked.

I have my own server (Wordpress etc) - what could I run to make this easy?

Ideally, I would like a webpage (username / password) that I can drag a file to and it creates a URL on my server that then when clicked on can share the file. Like a mini dropbox. Something really simple :)
