dtrace discuss - Sep 2007 - Foolproof way of getting hostid on Solaris 10

Dear Experts,

Is there a foolproof way of getting hostid on solaris 10 sparc?
I am asking this because i have seen Dtrace scripts  which allow to change
hostid. I want this because i want to tie down my application to specific host
and do not want my client to re-use it on other machine just by changing hostid.

Thanks,

Nope.

Sorry.  The system just won''t do that.

In general, I''d suggest not even attempting to do what you''re
apparently trying to do.  As a customer, I get highly annoyed when
some node-locked software fails after hardware upgrade, and I''ll do
just about anything to repair the situation.

Usually, that procedure involves not buying such software in the first
place.

And you want your client to curse you if they ever have to have
their hardware replaced?

Thanks James for speaking up for us.  We had a vendor wanting to
charge us US$30k for moving to a new license server when the old one
died (generation of new license file, manpower for re-install et. al).
 We hacked up an LD_PRELOAD solution in about 30 minutes to get around
that.

Sun has generally been much more reasonable than that for its
FlexLM licenses; still, a new license file is required.

(And I remember having multiple vendors all with their own FlexLM
license daemons as part of the package and the general issues with
interoperability of different versions).
