Cannot remote replicate filesysstems from/to Windows via netcat

[guenther-alka]

With my napp-it cs, I can manage ZFS boxes with BSD, Linux, OSX, Solaris/Illumos or Windows. Part of the project is the option to replicate pools from any source to any destination via napp-it cs replication jobs and netcat.

On Windows I use nc64 from
https://eternallybored.org/misc/netcat/

This works now for any OS combination - beside Windows as source or destination.

What I see on Windows
Local replication via zfs send snapshot | zfs receive -Fv filesystem: ok (from cmd shell, not working with powershell)

On a remote replication ex from Proxmox via
zfs send tank/data@neu | nc -w 30 192.168.2.76 51437

and on Windows side (cmd shell):
nc64 -l -w 20 -p 51437 | zfs receive -Fv tank/prox

I always get
nc64 -l -d -w 20 -p 51437 | zfs receive -Fv tank/prox
receiving full stream of tank/data@neu into tank/prox@neu
cannot receive new filesystem stream: invalid backup stream

Other way: Win 11->Proxmox

zfs send tank/data@neu | nc64 192.168.2.71 51437
11:02:08 312B tank/data@neu
11:02:08 4.09K tank/data@neu
.. longer list of last line
-> waiting/hanging

root@pve:~# nc -l -w 30 -p 51437 | zfs receive -Fv tank/win
receiving full stream of tank/data@neu into tank/win@neu
received 47.9K stream in 0.61 seconds (78.7K/sec)
-> waiting/hanging

I am not sure if this is a netcat on Windows problem or a ZFS on Windows problem. I use 2.2.3rc2 dirty. Anyone tried a network replication with netcat on Windows and success?

I have now tried nmap/netcat (another netcat option for Windows) with following result:
send Windows -> Proxmox: ok, success

send Proxmox -> Windows
\Nmap\ncat.exe -l -p 51437 | zfs receive -Fv tank/proxmox
receiving full stream of tank/data@neu into tank/proxmox@neu
cannot receive new filesystem stream: invalid backup stream
