I wanted to see if it was possible for gPXE to parse a text file to populate variables that can be used with an "Embedded Image" (ex. http://etherboot.org/wiki/scripting) or to read and execute gPXE command lines. The text file will contain network information. High level I was thinking something like this for the text file:
Variable Option: 192.168.1.1 255.255.255.0 192.168.1.0 Etc. If gPXE could read these into variables, I believe I could use this ex. http://etherboot.org/wiki/scripting . Obviously substituting the network information out for the variables gPXE read in. -OR- Command Line Option: set net0/ip 10.0.2.15 set net0/netmask 255.255.255.0 set net0/gateway 10.0.2.2 Etc. If gPXE can parse a line of text and then execute it, I believe this would solve my issue as well. So why am I trying to do this. DHCP/DNS are tightly controlled by another organization and still to this day DHCP/PXE will not be provided in a Data Center environment. What I want to do is have a static compiled version of a gPXE ISO where I can programmatically inject a text file into, that contains the appropriate network information for the server I'm about to build. A little background of how we do it now high level. We have a website that lists all the servers we own. A user will select a server to build and all the network information is pulled from a database. Then a script creates a WinPE ISO and injects server specific information (i.e. network information). It then injects the WinPE ISO into the out of band card (ex. iLO), boots/reboots the server, the server boots off the WinPE ISO, and builds the server. Basically I want to do the same thing with gPXE. Select server; script injects text file into gPXE ISO, ISO is injected into out of band card, server is powered on/rebooted, and server PXE boots. Any help would be appreciated! Thanks.
