How to use command line seeding and downloading file?

[zoudf]

Thanks for the great project!
My pc : Window8.1 -> created two VirtualBox machines: Ubuntu14.04.2 64 bit
In both Ubuntu installed Webtorrent & webtorrent-hybrid

I'm using command line in one example :A
zdf@zdf-VirtualBox64:~$ webtorrent-hybrid seed aa.txt
seeding: aa.txt
magnet uri: magnet:?xt=urn:btih:c53c2bb5059ad3406100cffdc269dbca7e57db40&dn=aa.txt&tr=udp%3A%2F%2Fopen.demonii.com%3A1337&tr=udp%3A%2F%2Ftracker.openbittorrent.com%3A80&tr=udp%3A%2F%2Ftracker.publicbt.com%3A80&tr=udp%3A%2F%2Ftracker.webtorrent.io%3A80&tr=wss%3A%2F%2Ftracker.webtorrent.io
speed: 0 B/s downloaded: 0 B/16 B uploaded: 0 B peers: 0/0 hotswaps: 0
time remaining: a few seconds remaining total time: 996s queued peers: 0 blocked: 0

In other example:B
zdf@zdf-VirtualBox64:~$ webtorrent-hybrid magnet:?xt=urn:btih:c53c2bb5059ad3406100cffdc269dbca7e57db40
fetching torrent metadata from 0 peers

No mater use webtorrent-hybrid or webtorrent command
"B" always not start download.

Eventually I use another PC open chrome -> instant.io download the hash upper.
It can download at instant.io! and then "B" downloaded from chrome

How to use command line only and transfer each other?

Webtorrent-hybrid won't work on windows, and webtorrent as a cli won't connect to web clients. I think that this issue might have something to do with that.

can you post your commands in windows as well?

[zoudf]

I don't run command line on windows
Just created 2 VirtualBox machines on my laptop and test command line, laptop is windows.
VirtualBox "A" ubuntu 64bit
VirtualBox "B" ubuntu 64bit

@ericwooley The webtorrent-hybrid CLI does connect to web clients, as well as to other webtorrent-hybrid clients, so his test case should work.

@zoudf My guess is that Virtualbox has a firewall that is blocking WebRTC connections. WebRTC usually finds a way to connect as long as one side doesn't have an overly restrictive NAT. In this case, with two VMs trying to connect to each other, I bet it's just failing to do NAT traversal.

Here's something that is more likely to work: Try seeding from one of the VMs and downloading from https://instant.io using your normal web browser outside the VM.

Another idea: try specifying a TURN relay server. This is a server that will get used to relay traffic between two peers that can't directly connect (like your two VMs).

Just use the rtcConfig parameter to the WebTorrent constructor to specify the server to use. For testing, you can use the config here: https://instant.io/rtcConfig but it's only good for 5 minutes, so this isn't suitable for use in production. Just to get your test working.

You can run your own TURN server or just use Twilio's service (it's super cheap).

@feross Sorry if I miscommunicated, but I meant that the webtorrent-hybrid CLI does, and the regular cli does not.

[feross]

@ericwooley Gotcha. Thanks for clarifying.

[zoudf]

@feross Yes, after changed VirtualBox machine network setting: NAT--> Bridge. It works well.
Thank you!

Nice.
