Dtella is an online peer to peer (P2P) file sharing network on Purdue’s campus. It is completely restricted to Purdue’s internal subnets. This is mostly included as a page here in case any other Purdue student wants to join it and/or needs help connecting. I have had just about every issue imaginable.
Personally, I am active on the IRC and consider many of the others on it to be friends, so I would suggest at least saying hi.
