6.2 Indy, ec0 gone missing?

Hi,

I wonder if anyone can help me shed some light on this situation.

I have a 6.2 Indy which functions as a print server, and I have some
stuff on the disks that I occasionally need to glance at. No monitor
plugged into this machine.

A few days ago it disappeared from the net. I plugged a screen in
and looked at the SYSLOG, which contains the following messages:

ec0: machine has bad ethernet address: 0c:00:6b:08:3c:20

....

WARNING: Failed to configure ec0 as hobbes
WARNING: Cannot access primary interface, ec0

....

objectserver[914]: netif verif: error in create

Further, ec0 doesn't show up in the hinv (it does in my 6.5 Indy),
which seems odd.

I thought the nvram had perhaps been zapped as it started playing
it's annoying power-up tune, which I had configured as off, suddenly.
Indeed the nvram netaddr was wrong, but fixing it had no effect.
"hosts" is OK, in any case I haven't changed any config files in a
long time. The nvram eaddr can't of course be changed anyway,
being the serial number AFAIK.

The first message is new. The second part comes from /etc/init.d/network,
the objectserver stuff is probably incidental.

Any ideas of things I might check? Does it sound like HW maybe?
The machine is over 10 years old...

My thanks in advance.

-E

Sounds like you need a new Dallas chip. You'll want to replace it, such as
described here <http://www.pimpworks.org/sgi/dallas.html>, but rather than order
the chip you might want to try asking for a free sample first. Never hurts to
try.

Thanks Tony. Culprit is found, and what's more thanks to that handy
site, I even managed to boot it onto the net and print some invoices...
Oh, frabjous day!

Cost of Dallas chip = 5% cost of 400 MHz octane 2, even in europe. Hmm,
makes me think...

] You may try the following incantation from the PROM monitor :

] fill -w -v 0x08 0xbfbe04e8
] fill -w -v 0x00 0xbfbe04ec
] fill -w -v 0xGG 0xbfbe04f0
] fill -w -v 0xHH 0xbfbe04f4
] fill -w -v 0xII 0xbfbe04f8
] fill -w -v 0xJJ 0xbfbe04fc
]
] replacing GGHHIIJJ with the correct values from the machine serial number.
] Turn off the machine, turn it on again. If this doesn't heal it, then the
] Dallas chip is probably fried. Oh, I forgot the black chicken, but you
] probably did know about the black chicken, didn't you? Smile

Now in my dotage I no longer wave the chicken, I eat it for dinner
prior to the manipulation. Baked in Hoisin sauce it was black though! :)

Apparently there's a little juice left in the Dallas still, because it came
up again today with the correct address.

Thanks again.
