[gentoo-user] diskless booting

[gentoo-user] diskless booting

[Roger Mason]

Hello,

I'm trying to boot a diskless machine, using the instructions in the
alternative installation guide.

The client boot process hangs, with the following dialog between the
server (192.168.0.2, 00:04:75:77:98:4f) and client (192.168.0.3,
00:01:03:ce:52:a8) repeated three times:

00:04:75:77:98:4f > 00:01:03:ce:52:a8, ARP, length 42: arp who-has
192.168.0.3 tell 192.168.0.2

I'm not sure what information is needed to help debug this, but if
anyone is willing to assist I'll provide whatever is required.

Thanks,

Roger Mason

what's the config for dhcp/tftp  and what are you using for PXE on the
client?

i think I might be able to help you.

Well, the configs were the same as the diskless install docs on the
Gentoo alt-install page, with suitable modifications of the ip and MAC
addresses in the dhcpd.conf.  I _was using pxegrub but, on a whim, I
tried syslinux instead as per the Gentoo diskless howto and, without
any further reconfiguration beyond pointing the client at pxelinix.0,
it booted first time.  After some tweaking of the client fstab and
hosts files it now works fine.

Thanks for the offer.  I'm planning to add some more clients now that
I have one working system.  I'm almost certain to get stuck so I'll
probably be back asking again.

Cheers,

Roger

I was going to suggest you avoid pxegrub, but I guess you figured that
out for yourself.

Let me know. 

By the way, if you're looking for performance enhancements to your
diskless hosts, let me know. I have found some, and am also always
looking for more.

What's wrong with pxe grub. I use it and it works, so I haven't tried
pxelinux. Is there a good reason to change if it works?

I never got it to work last January when I set up my first diskless
host.  I got similar strange errors; it just didn't seem to want to do
anything, although it appeared to be properly configured.

PXElinux was a breeze by comparison, I thought, even though the
configuration files are icky.  But most importantly, it worked, so I
stuck with it under the same principle.

I set up a CD-less client just for installation last week
and I did not succeed with PXElinux; then I used Pxegrub and
everything was fine. I admit I have not clue how to manage
an initramfs; with Pxegrub you need RootNFS which I finally
installed correctly after bothering this list with some
stupid posts ...

Well, I had it working on Friday but over the weeekend I tinkered some
more with pixegrub and broke it again.  Now pxelinux won't work
either.

I have the following dhcpd.conf on the host (192.168.0.2):

    option PXE.mtftp-ip 0.0.0.0;

  }

  host cctp {

          filename "pxelinux.0";
  }

}

allow bootp;
allow booting;
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

I have the following in.tftp on the host (192.168.0.2):

+in.tftpd++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

# /etc/init.d/in.tftpd

INTFTPD_PATH="/diskless"
INTFTPD_USER="nobody"

INTFTPD_OPTS="-v -s ${INTFTPD_PATH}"
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

I have bzImage, pxelinux.0 and pxelinux.cfg/ in /diskless on the
host. pxelinux.cfg/ contains a default file with these contents:

+pxelinux.cfg/default+++++++++++++++++++++++++++++++++++++++++++++++++

DEFAULT /bzImage
APPEND ip=dhcp root=/dev/nfs nfsroot=192.168.0.2:/diskless/calcite

When I try to boot the client, tcpdump -i eth1 prints the following

Right now I'd be happy to have it working, no matter how slowly.

One think I have found by searching the internet is that pxegrub has
history of poor interaction with 3Com cards, which is what I'm using.

Thanks for any help you can offer.

I've attached my dhcpd.conf, sans rndc-key.  Please note that this
configuration has a big block of code that is for dynamic DNS updates.
I kept it in because I found it hard to figure out for myself, and I
figured it would be better to put more out on the web rather than refer
you to sources I don't even know exist.  I don't know if you are
running BIND or a DNS server that can do static updates, but if you
can, I highly suggest it for your own sanity.  

For usefulness of online archives, which probably strip attachments,
here is the same info.  I even annotated it a little.

As soon as I sat down at the box this morning I spotted the problem,
which was incredibly stupid (but sadly self typical): I had named my
in.tftpd config file without the final "d".  Argh!  Now everything
seems to be running again.

I have kept a copy of your dhcpd.conf as a useful reference.

What I'm trying to accomplish is to build a kerrighed system.  Now on
to the next stage.

Thanks again for your help.

Best wishes,
Roger
