Re: Hey Festers - Let's Build a gPXE Build Server for the Installfest
So this will be a multiple os build server for use at install fests? PXE boot. Select dist and off it goes? With repository for some updates this could be huge, or we talking core install only. I definately have some hardware I would be willing to donate. How much horsepower will we need. An opteron 1212 or more?

Lisa, I could build a vm for that if you want. I could even give ssh access to it on a non-standard port if needed. I already have a vm of ubuntu already installed here. otherwise, I can save it off as an image and we can dd it to a new drive from a dvd. let me know. -Eric On Dec 29, 2010, at 9:35 PM, Lisa Kachold wrote: I promised to assist by building a gPXE build server for the Installfest.

Re: Hey Festers - Let's Build a gPXE Build Server for the Installfest
heh, ok. I use VM's here a lot because I don't have a large number of machines to use anymore. I haven't tried creating a PXE server though. that would be something new. and yeah, I suspect that booting PXE over the internet would not be doable except on a very secure, very fat pipe. :) anyway, it would be something new for me to learn. -Eric On Dec 29, 2010, at 11:01 PM, Lisa Kachold wrote: Thanks Technomage, That's not exactly what we require. A VM of what? Laugh! I can build a VM also, but why would I, when I can just build the system and configure the gPXE quicker?

Re: Hey Festers - Let's Build a gPXE Build Server for the Installfest
Also, VM bridging is not conducive to gPXE and besides WHY? We are using older equipment and we want all the Alan Cox'ian TCP/IP UDP sweetness that IS gPXE: *gPXE* (formerly *Etherboot*) is an open-sourcehttp://en.wikipedia.org/wiki/Open-source Preboot Execution Environmenthttp://en.wikipedia.org/wiki/Preboot_Execution_Environment(PXE) implementation and bootloader. It can be used to enable computers without built-in PXE support to boot from the network, or to extend an existing PXE implementation with support for additional protocols. While traditional PXE clients use TFTPhttp://en.wikipedia.org/wiki/Trivial_File_Transfer_Protocolto transfer data, gPXE adds the ability to retrieve data through other protocols like HTTPhttp://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol, iSCSI http://en.wikipedia.org/wiki/ISCSI and ATA over Ethernethttp://en.wikipedia.org/wiki/ATA_over_Ethernet(AoE), and can work with Wi-Fi http://en.wikipedia.org/wiki/Wi-Fi rather than requiring a wired connection.

This allows to use a PXE stack even if the network card has no boot ROMhttp://en.wikipedia.org/wiki/Read-only_memory, by loading gPXE from a fixed medium. Bootloader Although its basic role was to implement a PXE stack, gPXE can be used as a full-featured network bootloader. It can fetch files from multiple network protocols [1]http://en.wikipedia.org/wiki/GPXE#cite_note-Google_TechTalk_-_gPXE-0, such as TFTP, NFShttp://en.wikipedia.org/wiki/Network_File_System_%28protocol%29, HTTP[2]http://en.wikipedia.org/wiki/GPXE#cite_note-Booting_your_machine_over_HTTP-1or FTP http://en.wikipedia.org/wiki/File_Transfer_Protocol, and can boot PXE, ELF, Linux, FreeBSD http://en.wikipedia.org/wiki/FreeBSD, multiboothttp://en.wikipedia.org/wiki/Multiboot_Specification, EFI http://en.wikipedia.org/wiki/Extensible_Firmware_Interface and Windows CE http://en.wikipedia.org/wiki/Windows_CE images. In addition, it is scriptable and can load COMBOOT and COM32 SYSLINUXhttp://en.wikipedia.org/wiki/SYSLINUXextensions. This allows for instance to build a graphical menu for network boot.
