|
|
|
|
QFT is a small command line application for Quick Peer-To-Peer UDP file transfer.
|
|
|
|
|
|
|
|
|
|
## Usage:
|
|
|
|
|
- Find a public QFT helper (for example tudbut.de:4277)
|
|
|
|
|
- On the sender PC, enter `qft sender <helper> <shared-phrase> <filename>`.
|
|
|
|
|
- On the receiver PC, enter `qft receiver <helper> <shared-phrase> <filename>`.
|
|
|
|
|
- Both PCs should start transferring after a short while. If they don't, try again.
|
|
|
|
|
|
|
|
|
|
## Tips 'n Tricks
|
|
|
|
|
- You can add a number to the end of both of your commands (after the filename) to
|
|
|
|
|
boost transfer speeds (higher = faster), but a too large number might cause unreliability
|
|
|
|
|
due to local network conditions or VPNs.

|
|
- To use qfts and qftr aliases on linux or mac, run:
|
|
|
|
|
```sh
|
2022-08-15 12:26:07 +02:00
|
|
|
echo 'alias qftr="qft receiver tudbut.de:4277"' >> ~/.(shell)rc
|
|
|
|
|
echo 'alias qfts="qft sender tudbut.de:4277"' >> ~/.(shell)rc
|

|
|
|
```

## Troubleshooting
|
|
|
|
|
|
|
|
|
|
### It constantly says `CONNECTING`
|
|
|
|
|
One of your ends didn't correctly connect to the helper. Stop the transfer on both ends
|
2022-08-15 12:14:06 +02:00
|
|
|
and try again. If it still doesn't work, make SURE the time and date on both ends are within an
|
|
|
|
|
error of <0.1 seconds! Holepunching strongly relies on the time and date matching. (If you have any
|
|
|
|
|
suggestion on how I can mitigate this reliance on time, please open an issue!)
