PXE boot diskless?

Question

ubuntu

There is a task to run about 20 machines without hard drives so that the OS is loaded from the ubuntu 14.04 server
Tell me where to look and how to implement it

Answer 1

* DHCP server
* TFTP server
* NFS
* Syslinux (part of pxelinux.0, to be more precise)
* You can also use an HTTP server, I noticed that pulling the kernel and initrd from it is faster.
If you need win - similarly load some kind of distro like thinstation and make a terminal server on win-server.
