How do I use or host a private tracker in u torrent. I need to link my friends torrents and mine. I don't exactly know how these work so I would like some detailed infomation.
uTorrent has a complete guide on their website:
You want to look at the section where it talks about embedded trackers.
uTorrent contains everything you need. You don't need your own domain or your own website.
Your IP address does need to stay the same while the tracker is running. This is not normally an issue, but some home ISPs will change your IP if you are disconnected from the internet for a period.
A private tracker requires you to set up your own tracker server, which requires you to have a domain and website.
