SUMMARY: PXE boot from X4100 - Solaris 10 11/06

Thanks to Louis-Philippe Reid who pointed me in the direction of running
in.dhcpd with the -d and -v flags. This produced a stack of debugging
output, and I could see it wasn't listening on the correct interface, so
I manually added this with the -i flag.  This however didn't quite work
- I,ve listed my steps below both so I remember exactly what I did, and
also in case anyone else has this problem. Original post attached below.

My jumpstart server has a bunch of different subnets on it, and one of
these which I've been using for SPARC jumpstarts is on ipge0:2, EG not a
"real" NIC.

After running  /usr/lib/inet/in.dhcpd -dv -i ipge0:2 I could see the
dhcp server binding, and requests coming in, but it never offered a
response :

Dhcpagent in debug mode on the client, here's what it says :

/sbin/dhcpagent: debug: dhcp_selecting: DF_REQUEST_HOSTNAME
/sbin/dhcpagent: debug: select_best: no valid OFFER/BOOTP reply
/sbin/dhcpagent: debug: select_best: no valid OFFER/BOOTP reply
/sbin/dhcpagent: debug: select_best: no valid OFFER/BOOTP reply :

And here's the server :

45cc497d:  Datagram received on network device: ipge0:2(limited
broadcast)
45cc497d:  Client: 0100144F785C90 has DYNAMIC 192.168.3.4 owned by
server: 192.168.3.1.
45cc4981:  Datagram received on network device: ipge0:2(limited
broadcast)
45cc4981:  Client: 0100144F785C90 has DYNAMIC 192.168.3.4 owned by
server: 192.168.3.1.

And there it sat. A snoop also reveals that the jumpstart/DHCP server
was seeing the request, but it never responded. I then hit on the idea
that although the jumpstart server has a virtual NIC of 192.168.3.1,
maybe it didn't "know" that was itself - the debug output showed it
received a valid response, but it just sat there.

So, I then bound in.dhcpd to the real NIC as well as the virtual NIC :

/usr/lib/inet/in.dhcpd -dv -i ipge0:2,ipge0

And then re-configured the pntadm command, telling it that that lease
was owned by the "real" NICs IP address, 10.63.252.21. It looks a bit
odd in the pntadm output, but here it is :

$ pntadm -P 192.168.3.1
Client ID       Flags   Client IP       Server IP       Lease Expiration
Macro           Comment

0100144F785C90  01      192.168.3.4     10.63.252.21    Forever
0100144F785C90

Sure enough, debug shows it working :

45cc4e9f:  Datagram received on network device: ipge0(limited broadcast)
45cc4e9f:  Datagram received on network device: ipge0:2(limited
broadcast)
45cc4e9f:  ipge0(limited broadcast): There is no 10.63.252.0
dhcp-network table for DHCP client's network.
45cc4ea0:  Unicasting datagram to 192.168.3.4 address.
45cc4ea0:  Adding ARP entry: 192.168.3.4 == 00144F785C90
45cc4ea0:  Added offer: 192.168.3.4

Woot! So the moral of the story is that in.dhcpd doesn't seem to know
about any other IP addresses other than it's primary one. You don't need
to jumpstart and provide DHCP leases on that subnet, you just need to
use that address when configuring it through pntadm.

Hope this helps :)

Subject: PXE boot from X4100 - Solaris 10 11/06


Hi all,

I am having real problems getting Solaris 10 11/06 x64 booting from PXE
on a X4100. Any advice would be much appreciated, as I suspect I'm just
doing something really stupid here and messing up some syntax... I will
of course summarise and post here with any updates.

Jumpstart Server : T2000, Solaris 10, 01/06
Jumpstart Client : X4100, Solaris 10, 11/06 (version of Solaris added to
jumpstart server)

Systems are connected together via a 1GB switch. If I boot as normal
from the X4100 and configure a NIC, I can verify I can ping and "see"
the T2000.

The only thing complicating issues as far as I can see is that the T2000
jumpstart server is on several different networks, but the network set
aside for jumpstarting clients (192.168.3.0) has been succesfully used
to jumpstart SPARC systems before so it appears this is purely a
DHCP/PXE issue.

Here's the set of steps I follow :

# Start off by initialising DHCP (previously unconfigured with -U)
$ dhcpconfig -D -r SUNWbinfiles -p /var/dhcp

# Add the clients host name and MAC to /etc/hosts and /etc/ethers

# Add the install client, MAC address obtained by watching POST.
# 192.168.3.1 is the T2000s' IP address
$ ./add_install_client -d -e 00:14:4F:78:5C:90 -s
192.168.3.1:/export/software/jumpstart_x86 i86pc

If not already configured, enable PXE boot by creating
a macro named 0100144F785C90 with:
  Boot server IP (BootSrvA) : 10.63.252.21
  Boot file      (BootFile) : 0100144F785C90

# I ignore what it's telling me about the BootSrvA address, and use the
192.168.3.x range instead

# Create the table
$ pntadm -C 192.168.3.0

# Now I add the DHCP lease
$ pntadm -A 192.168.3.4 -f 01 -e 12/31/2010 -i 0100144F785C90 -m
0100144F785C90 -s 192.168.3.1 192.168.3.0

# Now add the macro
$ dhtadm -A -m 0100144F785C90 -d
":BootSrvA=192.168.3.1:BootFile=0100144F785C90:"

# Restart the DHCP server, and then try to boot from the X4100's PXE
boot

# PXE boot on the X4100 spits this out :
CLIENT MAC ADDR: 00 14 4F 78 5C 90  GUID: 00000000 0000 0000 0000
00144F6B8E3F
PXE-E51: No DHCP or proxyDHCP offers were received.

# This is what snoop shows me on the T2000
$ snoop ether 0:14:4f:78:5c:90
Using device /dev/ipge (promiscuous mode)
OLD-BROADCAST -> BROADCAST    DHCP/BOOTP DHCPDISCOVER
OLD-BROADCAST -> BROADCAST    DHCP/BOOTP DHCPDISCOVER
OLD-BROADCAST -> BROADCAST    DHCP/BOOTP DHCPDISCOVER
OLD-BROADCAST -> BROADCAST    DHCP/BOOTP DHCPDISCOVER

And I can also verify that UDP port 67 is listening on all interfaces :

$ netstat -na -P udp | grep 67
      *.67                                  Idle

What am I doing wrong ? Why is my DHCP server not responding to it's
requests ?

Thanks in advance,

-Mark
