Hi,

is it possible to change the MAC address of a NIC under hp-ux 10.2? Ifconfig
does not have the required option.

Thanks for any hints

Jens

I don't believe the major unices support that sort of thing, unless you
count Linux.

I'm pretty sure Solaris allows it, with something like:

ifconfig le0 ether <address>

Yes, you're right.  BSD lets you get away with that, too.  Please excuse
my mistake.

To the OP: I'm not sure about HP-UX, but "man ifconfig" is probably the
best place to start.  Out of curiosity, why do you need to do this?  I
know of a few reasons for it, but they're a bit nefarious...

All ethernet interfaces I've ever heard of come with a manufacturer's
assigned MAC address in the PROM and also allow it to be set in
software at power-up time, so there has to be a way.

In SAM, the display that sets the configuration for an interface is
usually used to set the IP number, but in HPUX 11 it displays the
MAC address as well so that's the place to start looking.  I don't
remember if that display also shows the MAC address on 10.

Any chance you can upgrade to a current version of the OS?

Sorry for two posts separated by seconds.  On most HP hardware models,
the PROM monitor has an option to configure the ethernet interface.
More often it is used to set it up for Ignite installs, but I recall
being able to alter the MAC address there.  Look at the monitor
settings not commands while HPUX is running.

Thanks for the help (also to the others). The problem is that a license
manager is using the MAC address as "dongle" but the original machine broke
down. The company we bought that licensed software from has been bought out
and went out of business, no additional support is available. (The beauty
of "professional" closed source software at work) So the easiest solution
seemed to be to change the MAC address to the one of the old machine.

Cheers

Jens
