| 1. A computer implemented method in a proxy server for a secure network install, wherein the proxy server is a trivial file
transfer protocol (TFTP) server, the computer implemented method comprising:
receiving a request for a boot image file from a client at the proxy server to form a received request, wherein the request
is for the secure network install by using a modified client remote boot control code, wherein the modified client remote
boot control code places the client in a Secure Bootfile Download Discovery (SBDD) mode, wherein the request for the boot
image file includes a location of the boot image file and a client Internet Protocol address, and wherein the proxy server
and the client are on a same subnet;
locating a boot image file server from a list of servers and corresponding boot image files for the boot image file by performing
a lookup of the boot image file in a mapping file to form a located boot image file, wherein the mapping file includes the
list of servers and corresponding boot image files;
identifying an Internet Protocol address of the boot image file server for the boot image file;
retrieving the located boot image file from the boot image file server using a secure file transfer protocol to form a retrieved
boot image file, wherein the secure file transfer protocol includes at least one of file encryption and checksum verification;
and
sending the retrieved boot image file to the client, wherein the client receives the client Internet Protocol address, the
location of the boot image file, and an Internet Protocol address of the proxy server from a dynamic host configuration protocol
server.
