Re: Lets try this again Help with bootp/dhcp

[Robert Thompson <robertt@stargate.cs.swau.edu>]

Well, I might not be too helpful, but I'll try:


|HOWTO facts.  So far, no luck.  The server apears to not even here the 
|Xterminal.  Statnet shows some rarp trafic.


Some Xterminals expect to get RARP answers instead of BOOTP
answers. RARP is an older protocol superceded by BOOTP and DHCP; BOOTP and
DHCP servers rarely also serve RARP requests. If you have a linux box on
your net, the linux kernel can be configured to provide a RARP server in
conjunction with a user-mode program.

From linux-2.2.14's Configure.help:

-SNIP-
Reverse ARP server
CONFIG_INET_RARP
  If there are (usually diskless or portable) machines on your local
  network that know their hardware Ethernet addresses but don't know
  their IP addresses upon startup, they can send out a Reverse Address
  Resolution Protocol (RARP) request to find out their own IP
  addresses. Diskless Sun 3 machines use this procedure at boot time,
  and diskless Linux boxes can be configured to do it as well.
  
  If you want your Linux box to be able to *answer* such requests,
  answer Y here; you'll then have to run the program rarp ("man rarp")
  on your box.

  If you actually want to use a diskless Sun 3 machine as an X
  terminal to Linux, say Y here and fetch Linux-Xkernel from
  ftp://metalab.unc.edu/pub/Linux/system/network/boot.net/.

  Superior solutions to the problem of booting and configuring
  machines over a net connection are given by the protocol BOOTP and
  its successor DHCP. See the DHCP FAQ
  http://web.syr.edu/~jmwobus/comfaqs/dhcp.faq.html for details (to
  browse the WWW, you need to have access to a machine on the Internet
  that has a program like lynx or netscape).

  If you want to compile RARP support as a module ( = code which can
  be inserted in and removed from the running kernel whenever you
  want), say M here and read Documentation/modules.txt. The module
  will be called rarp.o. 

  If you don't understand a word of the above, say N and rest in
  peace.

-SNIP-

If that was obvious, just tell me to shut up... =)
