next-server specifies the address of the server where the Linux kernel defined on the filename options is accessible via TFTP.

The solution is to add the MAC address of the Ethernet card in the DECstation statically to the ARP table of the TFTP server.

The firmware does not respond to ARP requests during a TFTP transfer. This leads to an ARP timeout and the transfer stops.

Tip: Isolating DHCP and TFTP to a different NIC will dramatically increase scalability.

You should also install the TFTP client package so that you can test whether the TFTP server works or not.
