WyzeCamV3 /media/mmc # ./dufs.mipsel-unknown-linux-musl  --allow-all /media/mmc
Error: Failed to bind `:::5000`

Caused by:
    Address family not supported by protocol (os error 124)

Environment:

  • Dufs version: 0.38.0
  • Browser/Webdav Info: Firefox 121.0
  • OS Info: Wyze cam v3, mipsel, Linux 3.10.14

Binary info:

It was compiled using Github action with:

RUSTFLAGS="-C target-feature=+crt-static" cross build --locked --release --target=mipsel-unknown-linux-musl --no-default-features

More info:

I compiled the binary statically because the camera firmware doesn't have musl library.

When running the dufs mipsel binary from my x64 laptop with qemu-user-static, dufs successfully runs and bind to my laptop IP address. However when running dufs form my camera, it seems to be unable to figure it's IP address as shown in the above log. Using bind address (-b option) with Unix socket works:

WyzeCamV3 /media/mmc # ./dufs.mipsel-unknown-linux-musl -b 0.0.0.0 --allow-all /media/mmc
Listening on:
  http://127.0.0.1:5000/

I can still make it work but don't know if this bug(maybe) is known, it would be nice to make a bug report.

If --bind is omitted, dufs will bind default addresses: 0.0.0.0 (IPv4), :: (IPv6).
Your mipsel device won't support IPv6, which is why the error occurred.

Mainstream devices all support IPv6. For the few devices that do not support IPv6, one must manually specify the bind address instead of using the default bind addresses.

dufs -b 0.0.0.0 -A

May I ask you more more thing?

Is there any way to run dufs in "detached" mode beside putting & behind the command? If there is no such an option, I suggest adding it.

No, please use systemd or something like that. @archandanime
