Hi Folks,
I've been trying hard to get a FreeBSD system booted via PXE with only
limited success. Maybe someone can have a look at my configs and shed a
little light on this for me.
Here's what happens at boot time:
Intel UNDI, PXE-2.0 (build 067)
Copyright (c) 1997, 1998 Intel Corporation
DHCP MAC ADDR
CLIENT ID: 192.168.254.133 MASK: 255.255.255.0 DHCP IP: 192.168.254.3

(root@matt.domain.com, Thu Nov 30 11:45:41 PST 2000)
pxe_open: server addr: 192.168.254.3
pxe_open: server path: /tftpboot
pxe_open: gateway ip: 192.168.254.1

Hit [Enter] to boot immediately, or any other key for command prompt.
Booting [kernel]...
\ (if using pxeboot)
can't load 'kernel' (if using pxeboot.tftp)
Because it'll be fetching the pxeboot file via tftp, it's set up as follows:
# grep tftp /etc/inetd.conf
tftp dgram udp wait nobody /usr/libexec/tftpd tftpd -l
/tftpboot
Since I've also tried to get it to work using TFTP for the kernel (as
opposed to NFS) I run inetd with the -R0 flag so that connections to inetd
services aren't rate limited.
# ps ax | grep inetd
1088 ?? Ss 0:00.01 inetd -wW -R0
My /tftpboot is set up as follows:
# ll /tftpboot/*
-rw-r--r-- 1 root wheel 2034 Nov 12 09:12 /tftpboot/install.cfg
-r-xr-xr-x 1 root wheel 2441176 Nov 30 11:54 /tftpboot/kernel
-rw-r--r-- 1 root wheel 2949120 Nov 30 11:57 /tftpboot/mfsroot
-rw-r--r-- 1 root wheel 165888 Nov 30 11:46 /tftpboot/pxeboot
-rw-r--r-- 1 root wheel 165888 Nov 30 11:47 /tftpboot/pxeboot.tftp
/tftpboot/boot:
-r--r--r-- 1 root wheel 512 Nov 11 16:57 boot1
-r--r--r-- 1 root wheel 7680 Nov 11 16:57 boot2
-r-xr-xr-x 1 root wheel 163840 Nov 11 16:57 loader
-rw-r--r-- 1 root wheel 190 Nov 30 12:51 loader.rc
-rw-r--r-- 1 root wheel 190 Nov 11 18:42 loader.rc.custom
-rw-r--r-- 1 root wheel 136 Nov 30 12:21 loader.rc.flp
All the files in the boot directory are off the 4.1-stable boot floppy. The
loader.rc.custom is the same as the example given on Alfred's page and the
.flp one is off the floppy.
The pxeboot and pxeboot.tftp are exactly what you'd expect. The pxeboot file
is the default pxeboot with NFS support and the pxeboot.tftp was generated
by editing the /etc/make.conf file, setting the TFTP flag and recompiling
pxeboot. The files definately are different because I can change the DHCP
file to point to the other file and get different results at boot time.
NFS is configured as follows:
matt# more /etc/exports
/ -alldirs -ro
/usr -alldirs -ro
/cdrom -alldirs -maproot=root -ro
matt# mount
/dev/ad0s2a on / (ufs, NFS exported, local)
/dev/ad0s2e on /usr (ufs, NFS exported, local)
/dev/acd0c on /cdrom (cd9660, NFS exported, local, read-only)
The DHCP server is a FreeBSD 4.2-stable system (make buildworld on
11/29/00). The DHCP server is isc-dhcp 3.0b2pl9 and is configured as shown:
option broadcast-address 192.168.254.255;
option domain-name-servers 192.168.254.3;
option domain-name "domain.com";
option routers 192.168.254.1;
option subnet-mask 255.255.255.0;
option space PXE;
option PXE.mtftp-ip code 1 = ip-address;
option PXE.mtftp-cport code 2 = unsigned integer 16;
option PXE.mtftp-sport code 3 = unsigned integer 16;
option PXE.mtftp-tmout code 4 = unsigned integer 8;
option PXE.mtftp-delay code 5 = unsigned integer 8;
server-name "DHCPserver";
server-identifier 192.168.254.3;
subnet 192.168.254.0 netmask 255.255.255.0 {
option routers 192.168.254.1;
option root-path "/tftpboot";
filename "pxeboot";
# filename "pxeboot.tftp"; (compiled for TFTP boot support vs
standard NFS)
range 192.168.254.32 192.168.254.99;
}
host c3.domain.com {
hardware ethernet 00:02:b3:1c:c6:02;
next-server 192.168.254.3;
fixed-address 192.168.254.133;
default-lease-time -1;
class "pxeclients"
{ match if substring (option vendor-class-identifier, 0, 9) =
"PXEClient";
option vendor-class-identifier "PXEClient";
option PXE.mtftp-ip 0.0.0.0;
vendor-option-space PXE;
}
}
So, what am I missing?
Matt
