Building

• This project uses go modules, so building is easy
• First, go 1.14+ must be installed (use buster-backports on debian)
• Then, run make inside the project's directory.
• This will get the dependencies and compile all the files.

Installing

To install, simply follow the building instructions and then run

• Linux: sudo make install
• macOS: sudo make install-macos

Using on iOS

Opensend can run on iOS using the iSH app.

• Install go using apk add go
• Clone this repository
• Run make
• Use opensend as normal, but skip device discovery
  • Device discovery does not work properly in iSH due to Alpine Linux
  • When running receiver, add --skip-mdns
  • When running sender, add --send-to <IP>
  • This applies bidirectionally
• Known issues
  • Opensend takes a while to become ready on iOS

Ports to whitelist
