[ipxe-devel] iPXE, iscsi, isc-dhcp on FreeBSD 10.x

[pathiaki2]

Hi,

I'm a little bit confused on using iPXE with isc-dhcp on legacy PXEboot.....

I've decided to go slow and use 192.168.0.x to test with.

Dhcpd.conf:

ddns-update-style none;
option routers 192.168.0.1;
option domain-name-servers 192.168.0.53;

(all the ipxe options)

option space ipxe;
option ipxe-encap-opts code 175 = encapsulate ipxe;
.
.
.
option ipxe.sdi code 40 = unsigned integer 8;
option ipxe.nfs code 41 = unsigned integer 8;

#subnet 192.168.0.0 netmask 255.255.255.0 {
#  use-host-decl-names on;
#  range 192.168.0.64 192.168.0.71;
#  default-lease-time 3600;
#  max-lease-time 86400;#       class "iPXE" {
#               match if option routers = "192.168.0.1";
#       }
#}

subnet 192.168.0.0 netmask 255.255.255.0 {
   use-host-decl-names on;
   range 192.168.0.64 192.168.0.71;
   default-lease-time 3600;
   max-lease-time 86400;
}

host laptop1.test.net {
         option domain-name "test.net";
         option routers 192.168.0.1;
         option subnet-mask 255.255.255.0;
         option broadcast-address 192.168.0.255;
         next-server 192.168.0.1;
         hardware ethernet 00:23:ae:14:a8:50;
         fixed-address 192.168.0.21;
         filename "boot/undionly.kpxe";
         option iscsi-initiator-iqn "iqn.2012-06.net.test:target0";
         option root-path 
"iscsi:192.168.0.1::::iqn.2012-06.net.test:target0";
#       if exists user-class and option user-class = "iPXE" {
#        filename "boot/undionly.kpxe";
#       } else {
#         filename "";
#         option root-path 
"iscsi:192.168.0.1::::iqn.2012-06.net.test:target0";
#       }
}

I installed the iscsi target from the laptop and made it the OS disk.
Everything went fine.

Now, I'm trying to PXEboot ye olde Dell Latitude 5500 laptop and I seem 
to be a wonderful circular loop.  As can be seen above, I've tried the 
chainload (I think) to keep it from going into the PXE loop.  (didn't 
seem to work).

Anyhow, it boots....

I get:

CLIENT MAC ADDR:  00 23 AE 14 A8 50 GUID <blather>
CLIENT IP: 192.168.021 MASK: 255.255.255.0 DHCP IP: 192.168.0.1

         UNDI device is PCI 09:00.0, type DIX+802.3

net0: 00:23:ae:14:a8:50 using undionly on UNDI-PCI09:00.0 (open)

Configuring (net0 00:23:ae:14:a8:50)...... ok
net0:  192.168.0.159/255.255.255.0 gw 192.168.0.1 <--- Different Address???
Nothing to boot:  No such file or directory (http://ipxe.org/2d03e13b)
No more network devices

Now, it seems it contacted the DHCP server a second time and got a 
different address?  Why?  (And how do I stop it from doing that?)

Also, when I go into the initial load where it says hit CTRL-B, I do so.

Everything looks good......

all the settings seem fine....

.
.
filename boot/undionly.kpxe
next-server    192.168.0.1
root-path  iscsi:192.168.0.1::::iqn.2012-06.net.test:target0
.
.
.
latptop1.test.net
.
.
.
manufacturer Dell
product Latitude E5500
serial G08DXG1
.
.


So, how do I keep the settings it has on the first load and keep it from 
contacting DHCP again?

Thank you,

P.
