I am unable to use Deluge torrent client in 12.04, i am confused about what setting should i use in preferences. It asks for various proxies - one for each of Peer, Seed, Tracker... I have used torrents only in windows before and configuring it was as easy as hell. I use internet on a WiFi LAN. thanks for any help.
Those are the same settings as in Windows.
Private trackers use HTTPS w/ auth and have DHT enabled. Many public trackers use DHT. Leave web seed off.
I believe your problems if they worked in windows are not related to proxy since those settings need not be adjusted unless you are re-routing traffic.
For example if I wanted to reroute to a specific server for additional security.
Is the torrent giving any tracker errors? Maybe you are on a bad tracker. If so add this to the tracker list
I don't know what exactly is your problem because it is too vague and proxy seems unrelated. Most problems occur due to bad trackers. I add more myself to remedy that.
