Hi,
my name is Walter Pezzini and I work for the Solaris Internet Sustaining Group
in Sun Microsystems.
We acknowledge the problem that you describe below.
A new bug has been filed today against it.
The patch will be fixed.
We are sorry for the inconveniences this bug caused you.
The patch was unfortunately tested and validated on systems
with Solaris 8 update 5 or later installed, and in that case the
problem you describe does not appear.
Thank you.
Regards.

Subject: [SUMMARY] Patch 109077-05 disabled DHCP (utadm/dhcpconfig)
Sorry, forgot to add [SUMMARY] to the Subject: line.
It's Friday, can I go home now?
Platform: SunOS eggshell 5.8 Generic_108528-07 sun4u sparc SUNW,Ultra-80
Solaris 8 (2/00)
Problem: Applying patch 109077-05 disables DHCP services (config
files no longer in expected format)
Please see my original question below for details of what this
patch did to my system. This is a Sunray server so it was urgent
that I get DHCP working again. As I said in my original post, the
patch did not backup files so backing out the patch wasn't an option
(I did NOT use the -d option to patchadd!).
I received confirmation from Casper Dik that this is inappropriate
behavior for a patch. It should have at least failed to install.
Casper suggested that I might need to upgrade to Solaris 8 10/01,
as this version updates several other packages that the patched
DHCP requires.
Nick Murray provided me with a fix, and pointed out that the new
dhcpmgr has a cool import/export function to allow you to exchange
data between DHCP implementations, but it won't support older formats
and the older version of dhcpmgr does not have the export function so
this wouldn't even be an option.
For the short term, I did the following to re-enable DHCP for
our Sunray network:
1) Remove Sunray interfaces: utadm -r
2) Rename /var/dhcp so utadm can reconfigure DHCP from scratch
(otherwise you get an internal error because the old files
are in an incompatible format)
3) Reconfigure the Sunray network interface and DHCP:
utadm -a qfe0
4) Run dhcpconfig to finally configure DHCP
My long-term solution is to upgrade our system to Solaris 8 10/01
and then re-install this patch. The Sunrays are working but I think
the upgrade will make things more consistent so we don't get bitten
down the road. I'll then use dhcpmgr to re-enable our local LAN
DHCP service.
Extra special thanks to Nick Murray for going out of his way,
and thanks to Casper Dik.

Problem: Applying patch 109077-05 disables DHCP services (config
files no longer in expected format)
I'm using this system as a Sunray server, so it's using DHCP
for the Sunrays. I've had some problems using DHCP to provide
public addresses for our LAN (not providing default router), so I
applied DHCP patch 109077-05 (Dec 18, 2001) in the hopes it would help.
Well, turns out it disables DHCP completely. Not only does DHCP
expect the configuration file which used to be /etc/default/dhcp to
be at /etc/inet/dhcpsvc.conf, but it seems to expect a completely
different format, with delimiter [TAB] replaced by '|' and the fields in a
different order. I've tried modifying my existing files but haven't
got it to work. To make matters worse, the patch apparently thought
it was overwriting packages of the same version, so it didn't bother
to save the original files. This patch is dated Dec 18 2001, so it
is not possible that the existing DHCP packages on my system were
the same version.
There is NOTHING in the "Special Installation Instructions" about
how to rectify this. At the beginning of the patch README there is
a vague warning that you should contact your Sun rep if you are not
familiar with DHCP configuration. It also states that there is a
"new configuration file" and startup script (which incidentally
won't start up DHCP without this config file), but provides no
more information.
So take this as a warning...do not apply this patch as it will
disable your DHCP services. The lack of helpful information in
the patch README is an example of supreme laziness on Sun's part,
IMHO.
Attached are copies of my original configuration files in case
that helps anyone decipher this.
