Thank you!
It is also working on the newest version 6.9.2.
netcat-openbsd by nerdpack (https://github.com/dmacias72/unRAID-NerdPack/blob/master/packages/6.9/netcat-openbsd-1.105-x86_64-2.tgz) is stucking after first WOL receive. Even with -w 1.
```
nc.openbsd -4 -vulkn -p 9 -w 1
Listening on [0.0.0.0] (family 2, port 9)
������RT�iRT�iRT�iRT�iRT�iRT�iRT�iRT�iRT�iRT�iRT�iRT�iRT�iRT�iRT�iRT�iConnection closed, listening again.
```
This version is running smooth and still listening to new connections.
best regards
