ndbootd - ND boot block server
ndbootd [ -dv ]
ndbootd sends boot blocks to diskless Sun-2 system clients that request
them using the (now obsolete) ND protocol. This server uses the boot
block contained in the file /tftpboot/sun2.bb. A client must appear in
the ethers(5) and hosts(5) databases, in order for the request to be
served. In determining whether to serve the client, ndbootd checks the
/tftpboot directory for a file whose name is the client's IP address in
hexadecimal notation. For example, if the file /tftpboot/C00901AD
exists, the machine at IP address 22.214.171.124 can be served. This file
normally contains the boot program that is sent to the client by
Only root can invoke ndbootd.
