nbdserve

Simple network block device server. Created because of usual nbd-server is tricky-ish to cross-compile. Also it typically requires config file, which is inconvenient for one-off use.

There are pre-built versions for Linux, Mac, Windows and Android on releases page.

IPv6 is supported, use options like -a [::1].

Windows

On windows, you can use with physical drives like so:

List physical drives:

wmic diskdrive list brief

Build and run (note that physical drives seem to only work in read only mode):

wmic diskdrive list brief
cargo build --release
.\target\release\nbdserve.exe --addr 0.0.0.0 \\.\PHYSICALDRIVE0 --read-only

You can use the firewall-rule.ps1 script to add the needed firewall rules to the windows firewall.
