rs9p

Tokio-based asynchronous filesystems library using 9P2000.L protocol, an extended variant of 9P from Plan 9.

unpfs

unpfs is the reference implementation of a file server which exports your filesystem. You can build unpfs with the following commands below:

cargo build -p unpfs --verbose --release

and run unpfs with the following command to export /exportdir:

# TCP
cargo run --release -- 'tcp!0.0.0.0!564' /exportdir

# Unix domain socket:
#  port number is a suffix to the unix domain socket
#  'unix!/tmp/unpfs-socket!n' creates `/tmp/unpfs-socket:n`
cargo run --release -- 'unix!/tmp/unpfs-socket!0' /exportdir

# With maximum depth limit (prevents infinite recursion)
cargo run --release -- --max-depth 100 'tcp!0.0.0.0!564' /exportdir

Important: If you mount the filesystem inside its own export directory, you can create infinite recursion (e.g., exporting /home/user and mounting at /home/user/mnt creates /home/user/mnt/mnt/mnt/...). Use the --max-depth option to prevent this:

cargo run --release -- --max-depth 50 'tcp!0.0.0.0!564' /exportdir

You are now ready to import/mount the remote filesystem. Let's mount it at /mountdir:

# TCP
sudo mount -t 9p -o version=9p2000.L,trans=tcp,port=564,uname=$USER 127.0.0.1 /mountdir
# Unix domain socket
sudo mount -t 9p -o version=9p2000.L,trans=unix,uname=$USER /tmp/unpfs-socket:0 /mountdir
