[9fans] PXE tftpload: file does not exist

[9fans] PXE tftpload: file does not exist

[Marco Feichtinger]

I have a standalone file server, and a separate standalone auth server.

I tried to pxe boot a cpu server.
It gets the /386/9boot to load fine, but then it seems, that it can’t retrieve the file /cfg/pxe/<mac address> from my file server.

here is the screen output during bootup:
        9boot gz…starting protected-mode loader at 0x900020
        
        Plan 9 from Bell Labs PXE boot loader
        cpu0: 1800MHz GenuineIntel Atom (cpuid: AX 0x106CA DX 0xBFEBFBFF)
        ELCR: CC80
        #l0: i82598: 10Gbps port 0XFE980000 irq 11: <mac address>
        #l0: i82598: 10Gbps port 0XFE980000 irq 10: <mac address>
        498M memory: 498M kernel data, 0M user, 18M swap
        pxe on ether0 .
        <sysname> (10.0.10.1!69): /cfg/pxe/<mac address> .T.T.T.T.T.T.T.T.T.Ttftpread1st: failed to connect to server (10.0.10.1!69)

        failed.
        tftpload: file does not exist

Which is strange, because I did create the file on my file server.
It looks like following:
        bootfile=ether0!/386/9pccpuf
        nobootprompt=tcp
        readparts=1
        mouseport=2
        monitor=vesa
        vgasize=1024x768x8
        user=bootes
        sysname=<sysname>

Does anyone know what might be the problem?
Thanks.

[Steve Simon]

are you running the tftp server?

yes, ip/dhcpd and ip/tftpd are running on the file server

Re: [9fans] PXE tftpload: file does not exist

The error was caused by a misconfigured ndb.
Thanks to Frank D. Engel Jr., which gave me the hint in a separat email.

So I played around with my ndb files, and concluded,… that I don’t quit understand how the ndb works.
Given following basic ndb configuration:
; cat /lib/ndb/local

#
#  files comprising the database, use as many as you like, see ndb(6)
#
database=
        file=/lib/ndb/local
        file=/lib/ndb/common

#
#  because the public demands the name localsource
#
ip=127.0.0.1 sys=localhost dom=localhost

#
#  main network for home.csr.germteig.com
#
ipnet=main ip=10.0.0.0 ipmask=255.0.0.0
ipsubmask=255.255.0.0

#
#  server subnetwork
#
ipnet=srv ip=10.0.0.0 ipmask=255.255.0.0
        fs=fs.main.com
        auth=auth.main.com
        authdom=servers.main.com

sys=auth
        ip=10.0.0.3 ether=<mac address>
        dom=auth.main.com

sys=cpu
        ip=10.0.0.4 ether=<mac address>
        ip=10.0.0.5 ether=<mac address>
        dom=cpu.main.com
        bootf=/386/9boot

sys=fs
        ip=10.0.0.10 ether=<mac address>
        ip=10.0.0.11 ether=<mac address>
        dom=fs.main.com
;

With that, the cpu server boots just fine.
It reads its config file under /cfg/pxe/ and loads the kernel.

Now if I change the ip address of that cpu server to following:
sys=cpu
        ip=10.0.1.4 ether=<mac address>
        ip=10.0.1.5 ether=<mac address>
        dom=cpu.main.com
        bootf=/386/9boot

Then I get the error "tftpload: file does not exist”.
But why?

Re: [9fans] PXE tftpload: file does not exist

[vic.thacker]

Just a hunch, but perhaps you haven't added the cpu server kernel to /lib/tftpd to be loaded.
