Furumi-ng

Remote filesystem over gRPC. Mount a directory from a remote server as a local folder via FUSE.

Designed for streaming media (video, music) over the network.

Architecture

furumi-server (gRPC)  ←→  furumi-client-core (library)  ←→  furumi-mount-linux (FUSE)

• furumi-server — exposes a directory over gRPC with optional Bearer token auth and Prometheus metrics
• furumi-client-core — cross-platform gRPC client library with attribute caching
• furumi-mount-linux — mounts the remote directory locally via FUSE (read-only)

Quick Start

# Build
cargo build --release --workspace

# Server
./target/release/furumi-server \
  --root /path/to/media \
  --bind 0.0.0.0:50051 \
  --token mysecrettoken

# Client (on another machine)
mkdir -p /mnt/remote
./target/release/furumi-mount-linux \
  --server http://server-ip:50051 \
  --token mysecrettoken \
  --mount /mnt/remote

# Use it
ls /mnt/remote
mpv /mnt/remote/video.mkv
