We've been mandated to migrate our network boot from /etc/ethers &
/etc/hosts to using DHCP. It was working, I say was because every
network boot involved 4 timeouts then a restart of the process before
working. Now it continuously timesout waiting for the BOOTP.DHCP reply.
I've sniffed the network and found the following sequence:

Client sends DHCPDISCOVER
Server sends DHCPOFFER (with all the required data)
Client sends DHCPREQUEST (with the server, address, etc defined)
At this point the server does not send a DHCPACK, so the client
timesout and resends the DHCPREQUEST.

If I boot the client off the hard disk and request DHCP network
configuration, the server does send the DHCPACK, thus that process
works.

I'm looking for any ideas on how to proceed with debugging this.

What sort of client? What are you using as the DHCP server? What's in
the DHCP server's logs? Can't tell you much with the information
provided here.

Server: Sun-Fire V210 Running 5.9

Client: UltraAX-i2

I're using DHCP on the Sun-Fire V210 server.

I've set the DHCP Server debug level to Verbose, yet we see nothing in
syslog

Following is the output from snoop during a boot attempt:

The DISCOVER shows:

The OFFER shows:

> ETHER:

The REQUEST shows:

> ETHER: ----- Ether Header -----
> ETHER:

In other words, it seems that the client has taken 15 seconds before
responding to the OFFER, and assuming the default of 10 seconds for
OFFER_CACHE_TIMEOUT from the /etc/inet/dhcpsvc.conf file applies ...
Bye-Bye client!

That could be, though the trace also shows it falling back and retrying,
and in that case (packets 8 & 9) the gap is only 7 seconds and the
behavior is the same.

More likely is that you're running into an offer problem which isn't
shown directly by this snoop trace, but known; it's CR 6220012 and for
Solaris 9 SPARC you should try patch 112837-09.

Thanks greatly. That was the problem. I increased the timeout to 30
seconds and now the network boot succeeds. Now to figure out why the
client is taking so long to send the REQUEST, appearantly something has
changed to increase this delay.

Thanks again.
