I have a beefy Linux box that I use for development. One of the things this box does is run KVM instances that run a Triton headnode and several compute nodes.
I have a single gigabit link to the outside world. All networks are able to reach the outside world via NAT.
This document covers how to setup netboot.xyz, a service that provides iPXE-based installation and live boot of a bunch of operating systems, on a Ubiquiti EdgeRouter.
I've made a few assumptions throughout this document that will probably be different for your setup:
| # Self routing cluster example | |
| vcl 4.0; | |
| import directors; | |
| backend node1 { | |
| .host = "node1.example.com"; | |
| .port = "80"; | |
| } |
This documents my setup of a SmartOS server as my PPPoE router, providing DNS/DHCP services to the local network.
Basic setup:
| local logfile = require("logfile") | |
| local P = require("posix") | |
| local cjson = require("cjson") | |
| local cookies = require("http_cookies") | |
| local _M = { | |
| fatal = 60, | |
| error = 50, | |
| warn = 40, |
