PXE boot with NBD

[billium]

I am able to boot with PXE and nfs but now want to try NBD

My NBD server on Debian Jessie will not accept port numbers like the tinycore netbooting wiki states.

I have tested my server with "nbd-client 192.168.3.3 /dev/nbd0 -N tinycore" on another computer and it works o.k., but I cannot work out how to put "-N tinycore" in the pxe config statement.

Could someone please tell me where I can find the PXE NBD syntax for booting tinycore with label rather than port number.

Thanks for Tiny Core.

I should also state that if I put  oldstyle = true in the server config it works.

But when testing and using my nbd server on debian stretch i get:

Warning: the oldstyle protocol is no longer supported.
This method now uses the newstyle protocol with a default export
Negotiation: .Error: It looks like you're trying to connect to an oldstyle server. This is no longer supported since nbd 3.10.
Exiting.

This is why I am requesting the syntax for the new style nbd as I have not been able to work it out.

I know this post is a couple years old, but I am having the exact same problem. Were you ever able to resolve this?
