Re: [BProc] undocumented features

[Peter B. <pz...@da...>]

Hello,

I should preface the following with a note that this is based on the
Scyld product with uses bproc 2.2.x and the 2.2 kernel, but beoboot can
be easily modified to work with bproc 3.x and the 2.4 kernel. 
Additionally, Erik has mentioned that he has a new version that he will
be releasing in the future.  The comments below are based on the older
version, as I have not seen the new version.

No, bpmaster cannot do DHCP or RARP, however the beoserv program that is
part of beoboot can respond to RARP requests.  It also uses the
/etc/beowulf/config file as its config file, so the entries for ignore
are for beoserv.

Beoserv and two kernel monte, linuxbios, or kexec can replace tftp.  The
bootfile and bootport entries are for beoserv and monte, but it could be
modified to work with LinuxBIOS or kexec.

I hope to release an updated version of beoboot that can work with bproc
3.x in the near future.  This is only a hold over until the new version
is available, and still uses the old ELF linker code.

Thanks.

[BProc] undocumented features

[J . A . M. <jam...@ab...>]

Hi.

I have been reading the nre docs from Sept 26, but I have not found
any reference to this part of the demo config file:

# Ignored nodes
# Don't respond to these boxes RARP requests
#ignore 00:C0:CA:10:94:14 

#
# Beowulf Boot File
#
bootport 1556
bootfile /home/hendriks/beoboot/boot.img

So:
- can bpmaster directly do MAC-IP answers, so I can get rid of dhcp ?
- can bpmaster directly return a kernel image, so I do not need tftp ?

Thanks.
