On occasion I find myself needing to send a file at least a few gigabytes in size to a friend across our slow ISPs but haven’t found a satisfying solution. I usually end up creating a private torrent with the announce address of my own IP. Even though it’s slow - it basically never reaches my max upload speed for some reason, it is at least resilient if there are ever any network glitches.
Does anyone else face this same challenge?
EDIT: Thank you for the awesome suggestions! I have some homework to do on these
Syncthing has public releays enabling it to work (dunno if one or none need to be public) without both parties being exposed.
I mean… exposed to each other, sure, but they’re all exposed to Syncthing and the public relays.
