I'm using Gentoo Linux and yesterday I installed Qtella, and couldn't connect. So I visited
Qtella's homepage and found a hostlist file (in Host Cache List section). I tried to use it, but it couldn't help with my connection. So I started gtk-gnutella, let it connect (it works perfectly), wrote down some IPs it was using, closed gtk-gnutella and used the same IPs for Qtella. IT WORKS! But I think this is not the way Qtella was thought to be used...
