[9fans] How to find or build 9pxeload?

[Peter Hull]

 Hi all,
I was looking at booting via PXE (this is all just on Virtual Box
VMs). I need to provide a 9pxeload in the boot process but I can't
find it in my distribution and I can't understand how to build it. I
looked in the source tree but 9pxeload doesn't seem to be a target in
the makefile.

How can I build 9pxeload? (I am using plan 9 from Bell Labs, not
9front or 9atom)

Thanks,
Peter

9pxeload has been replaced by 9boot since the new boot loader
replaced the old one in the distribution in May 2012.

OK, brilliant, thanks for the swift reply. I didn’t see that written down anywhere!

9pxeload is still found in 9atom, as is cinap's iplpxe, which is
much better.  it sets ether0 to the interface that pxe'd, avoiding
manual setting.

"iplpxe" is the most stupid name ever. tuttle is not amused.
its called 9boot on the front. central cervices has to screw
everything up... oh the paper work... ;-)

thank you.  my new claim to fame.

as long as we're abolishing 360 jokes, what do you call "dd" in 9front,

I like it!

I didn't understand any of the last 3 messages* but,
I've got tftpd and dhcpd up and running; I can see the
discover-offer-request-ack in /sys/log/ipboot. I see /386/9boot being
transferred by tftpd. 9boot seems to load ok, on the client I see
9boot.gz... starting protected-mode loader at 0x900020
but then a bit lower down
pxe on ether0 .T.T.T.T.T.T bootp on ether0 timed out
then it just repeats.
I'd expect it to be trying to load plan9.ini from /cfg/pxe/<MAC> by
now, yet don't see anything like that in the ipboot log. I see
bootp 0.0.0.0->10.0.2.9 from hwa01_080027835578 vie 10.0.2.9, file broadcast
bootp via 255.255.255.255: file /386/9boot xid(300000) flag(8000) ...

What am I missing (sorry to keep asking)
Thanks,
Pete

understand plan9!!!

pxe doesn't know how to decompress.

So, what? It's, like, stressed out *all* the time?

Not quite sure how that's happening, 9boot on my disk isn't a .gz file
and I can't see any options to tftpd that are requesting compression.
Isn't 9boot running OK by then - and the errors coming from the next step?
Thanks for your help,
Pete

what is bootf in the ndb entry for the host that is supposed to pxe boot?
ndb/query ether $myether bootf

don't know then.  the original post mentioned loading 9boot.gz.
i'd think that /386/9boot would work.  you might try
iplpxe from 9atom, or the 9front 9boot, which is completely
different than the sources program by the same name.  either one
might give better results.

9boot (I think) comprises a stub and a compressed executable; once the
whole thing is loaded it decompresses the real 9boot and runs it. I do
think 9boot is running OK, it seems to fail when it goes back to bootp
to get its Ethernet config, hence the .T.T part of what it prints out.
I'll try those other distributions as you suggest.

OK got it now. I was specifying the wrong network card to VirtualBox,
the 'Intel PRO/1000 MT Server' works and the 'Desktop' doesn't. Now I
can TFTP boot but so far can't start a graphical session. That's for
the next email...

Thanks,
