you can set things up so that a cpu server running on a PC takes its IP address
and other network parameters from the plan9.ini file, which is useful when the
cpu server itself is the dhcp server for the network.  you don't need another
system to act as dhcp server.

That's exactly what I need!
But unfortunately I don't know how to make it. I have read
man for plan9.ini and there is no such option. (except some
"fs=..." and "auth=..." parameters but I think it is not what
I am looking for)
Could you place here some example or URL for doc, plese?
Thanks!

I got it! On boot prompt "root is from:" I can place the same options
as to ipconfig. So I wrote to plan9.ini:

bootargs=il ether /net/ether0 a.b.c.d

That's OK.
But then loader asks for addresses of fs & auth servers.
Does anybody know how to set this to default values,
so it can boot without interaction with user on keyboard?

I got the first byte wrong in that last message, i left it decimal.  The string
should have been:

2b:0c:80:04:<4 bytes of fs addr>:81:04:<4 bytes of auth server addr>

That's the vendor-encapsulated-options (2b) containing 12 bytes.
The encapsluated options are plan9 file server 80 and plan9
auth server 81.

Re: [9fans] il: no success with DHCP

[presotto]

It could be that they no longer recognize 'vendor-encapsulated-options'.
You could just speciffy your own option of:

	43:0c:80:04:<4 bytes of fs addr>:81:04:<4 bytes of auth server addr>

This is just the byte string that the 'vendor-encapsulated-options' was
supposed to create.

//Do I need another machine with DHCP service?

yes. the file server does _only_ services 9p requests.
anything beyond that, like dhcp, tftp, authentication,
and you've got to be running a CPU server, or make
other accomidations.

I can confirm this: I use NetBSD with ISC dhcpd (thanks, Ted Lemon) to
start up even the compute and file servers.  Which brings me to a
question I have been meaning to ask Presotto about: the vendor values
he gave me worked fine until I upgraded to the latest version of
NetBSD and, presumably, a later version of ISC dhcpd.  For some
reason, they are no longer understood by the kernel.  They used to be:

	option vendor-encapsulated-options 80:04:c0:60:20:86:81:04:c0:60:20:85;

and I can't find any documentation to instruct me how I should change
them.  I guess I should join the dhcpd mailing list and ask there, but
I really have only one query :-(

[9fans] il: no success with DHCP

[vecera]

Hello all,

I have installed files from distribution archive to my fileserver.
I made floppy with pccpu.gz for my auth/cpuserver.

Then with only fileserver running I try to boot
cpuserver from floppy (as diskless) with root from il.
But it complains:

il: no success with DHCP

Can you help me, please?
Do I need another machine with DHCP service?
