As far as i am aware there is not a plugin for abyss web server but if you want to run an ftp server, i would highly recommend Bulletproof FTP. Please feel free to get back to me on this if you want some help setting it up/advise, on the following addy ricki_young12@hotmail.com
I use this to run 2 ftp servers at home/work
