I'm trying to create a torrent to share a large number of pictures with my family, but I can't get the upload to work. As a proof of concept I'm first trying to seed and leech the file to myself. Here's what I tried:
In ~/torrent_upload:
ctorrent -t -u "udp://tracker.coppersurfer.tk:6969/announce" -s example.torrent ./data.zip
cp ./example.torrent ../torrent_download/example.torrent
ctorrent ./example.torrent
In ~/torrent_download:
ctorrent ./example.torrent
Here are the outputs:
For torrent_upload:

again with final line staying at Connecting. Running ctorrents in verbal mode doesn't really add any useful info. I just see repeating lines similar to:
1484220255 Cache: 0K/16M Hits: 0 Miss: 0 0% Pre: 0/0

- 0/0/1 [712/712/712] 0MB,0MB | 0,0K/s | 0,0K E:0,0 Connecting
on both processes.
Any idea what am I missing? Reading around some people say it's a port issue and I need to open the port in router to allow upload, although not everyone seems to agree with that. I tred opening port 2706 that uploading ctorrent was listening on, but that didn't change anything.
Others are blaming tracker sites. I don't know how to verify if a tracker I use works or not, but I tried several, all with the same result.
I thought maybe tracker sites need some time to start wiring peers, but I left both upload and download processes overnight and it didn't work.
I already set my IP address to static - and at any rate I think it shouldn't matter considering I'm doing essentially local to local connection now.
I tried downloading popular torrents, like Ubuntu images, to make sure download part isn't broken and it works like a charm.
EDIT in response to Seth's questions:
I tried seeding latest Ubuntu ISO on two different machines. Running in normal mode it looked like nothing was uploaded, but here are excerpts of verbose mode:

It looks to me like some communication with peers is going on, though without any upload. Can't tell if that's because of some errors (e.g bad handsake, unknown message type 20, etc messages) or simply because Ubuntu is such a popular torrent that no peer needed anything from me.
I also tried seeding my torrent on one machine and downloading on another and see that both of them report repeated:
| 0/0/1 [712/712/712] 0MB,0MB | 0,0K/s | 0,0K E:0,0 Connecting
warn, connect to tracker failed: Operation timed out
so it looks like a tracker problem after all. But I have that message with a bunch on different trackers I tried, so maybe it is something on my side that prevents communication with trackers, e.g. in how I created the torrent.
