OK I have read the HowTo here http://btfaq.com/serve/cache/56.html and I have also watched the tutorial video here http://www.poromenos.org/tutorials/bittorrent (neither of which relate directly to KTorrent) but I cannot get my own torrents to Upload to anyone (or Download from my home computer to another). I am not sure if it is a port issue, or a UDP-something, or....?

I am using KTorrent at home and I want to make a .torrent of photos and then email the .torrent to a friend and have them download those photos via BitTorrent. Unfortunately, in my download test (using Azureus on a Windows machine), I have "0(1)" Peers (zero connected, one in swarm - the host, aka my home machine with KTorrent) but my client won't connect to it; I have "0(0)" in my Seeds column (meaning my home host machine (KTorrent) isn't seeding my torrent). I've tried this using Azureus at home also, but the same result - no seeding so the clients cannot connect to it.

My guess is that it wants a central Tracker or Repository or something, but I don't want to do that...

Any way to seed with KTorrent without giving in to the man?

You need to register torrent that you create with some public tracker (try thepiratebay.org, demonoid.com or google for some better). Or you can run your own tracker and use that address.

So, when you create this torrent of yours in, copy/paste trackers URL in appropriate editBox in KTorrent make torrent dialog.

After all this, just seed and mail the torrent file to your friend. This should do it.

What exactly is a tracker URL? How would I make my own tracker? If you could be so kinda as to point me in the right direction...

So it does indeed sound like I need to have a central repository -- since uTorrent doesn't ned to have this, its a feature request I am going to put in for KTorrent...

A tracker URL is just a link to the tracker so the client knows where to announce to. KTorrent has no built-in tracker, so you might have to install specific software for that and configure the system for it (though, can be some work). Or you can use the Azureus built-in tracker functionality.

Personally, for just a few files, i would rather use the KDE "public file server" by adding it to the panel. Be sure you know the guy his IP before you start it though.

Ivan made this possible recently:
