Will hostid change with IP address?

[Fredrik Uddin-Backman2]

Hi

Does the hostid change when changing IP address on an otherwise unchanged system (HP-UX 11.11)?

[Torsten.]

What exactly do you mean by "hostid"?

[Fredrik Uddin-Backman2]

hostid = output from this command

echo `/bin/uname -i` 16op | dc

That gives me the hostid that in my case Legato Networker is licensed for.

[Torsten.]

The result of

# uname -i


is the unique machine identification number.
This is bound to the hardware - IP addresses, hostnames or anything doesn't matter at all.

Shalom Fredrik,

hostid in this context is like a MAC address for a NIC card.

Its not going to change based on changing the IP address because its hardware based information.

It won't change by changing IP address/hostname etc.

As mentioned above it is unique and generated based on product id and serial no. of system board. It changes when system board is changed that is when we have to retain the same, but HP CE takes care of that part as well.

So as long as u r doing configuration changes its not going to affect hostid.

[Torsten.]

The unique machine identification number (aka Software ID) is calculated based on machines model and serial - or for very old systems based on the core I/O MAC address.

You will find the same value if you run "machinfo" on supported systems or run the STM info tool against the system or CPU.

Ok, thanks to you all
