As many of your out there have come across the same problem, this series of web pages is being provided to help offer some direction in understanding the present process of net booting some of the new macintosh machines. (Any G3 (blue/white series or later) and iMac (any color series available as of this writing.))
As a side effect of this research, I found it was possible to net boot the entire OS for a newer G3 (or better) or iMac from a Linux Box running DHCP Server, TFTP Server, and the Asun Netatalk. (Information on how this was done is included on this site too.)
This setup is not for the faint of heart, nor is it packaged in a nice RPM (here, but Rob Lineweaver has ported these ISC DHCP v2 patches to ISC's DHCP v3 servers and rolled a binary RPM package for some common linux distros (See the how-to and patches section for where to download patchs and the choices you have in patches.) Note: this does not include the MacOS system, or the other "standard" support packages needed and you will still need to do some work), or DEB format for easy installation. If you want to do this, will need to patch a source tree (DHCP), compile code (like DHCP and others if you need them and cannot find a package for them.) I will try to document the procedure in a step by step format for those that may need it. Did I miss a step? Let me know and I will try to add it to the procedure.
The focus of this web site is to describe what has been possible, explain some of the problems with how Apple chose to implement it for large organizations to use, and describe the products of reverse engineering their netbooting system.
- A Brief review for setting up the Mac OS X Net-Booting Server may be of some assistance to those that need to re-familiarize them-self with the setup again.(Incomplete as of 10-11-99. If anyone would like to add more, please submit a text file with the changes, or put up a web page, and let me know the link! (thanks))
- The problem with Mac OS X Net-Booting server on large campuses is discussed in limited detail with some possible solutions. Some costly with hours of administration, other costly with devices, and others costly with both devices and hours of administration.
- DHCP-Response Analysis: Understanding what was going on at the network and transport and application levels became the next step. After a complete review, the only non-standard part of DHCP/BootP, TFTP, and AFP/FS/IP was the DHCP/BootP server response, so this difference is discussed here in more detail.
- Duplicating the Mac OS X Server BootP/DHCP Response: Creating an entry in my *NIX box /etc/dhcpd.conf (in this case it was a Linux Laptop) to offer the netbooting Macintosh the information it needs to continue its booting process from an arbitrary tftp, and AFP/FS/IP server for each of the needed shares was the next step in this process. On the page, to which this link takes you, are links to a CGI that can take your text based information and make an entry for dhcpd.conf that may work on your network.
- Patches (and information on how-to) were required to DHCP's source code to allow the DHCP server to package all of the vendor specific options into the return response without exceeding the standard's 64 byte maximum unless the client offers a Maximum Message Size that is larger. These patches patch DHCP in different ways so as to allow for the above link's Form to CGI output to work properly.
- Security issues in making this choice are something you *really* should examine before making your decision. If you have more to offer than what I have posted, let me know and I can add your statements here too.
