Is it possible to have an unique host ID ?

man hostid:

NAME hostid - set or print system's host id.

SYNTAX hostid [-v] [decimal-id] DESCRIPTION The hostid command prints the current host id number in hexadecimal and both decimal and hexadecimal in paren‐ thesis if the -v option is given. This numeric value is expected to be unique across all hosts and is nor‐ mally set to resemble the host's Internet address. ...

You can apparently set the id to whatever you want by calling hostid at startup, but you must ensure that each host has a unique ID.

I set the id by calling hostid is OK. Each time I reboot 2 time the PC and the host ID is always the same. But when I install Maple 10, at the end of installation I have the message : "Unable to determine the host ID of your system" The Maple install process may be use a different fonction of hostid. If I install SuSE 10.1 with the DVD on the same PC, I don't have the problem to install Maple 10. I used ghost on 32 PC and I don't want to reinstall all PCs with the DVD or via NFS.

Nobody had an idea ?

Hi Fabien, I didn't respond because I didn't have an answer for you. But I *did* have an "idea"... could be right... could be wrong... so no guarantee, of course. But my first reaction was maybe the Maple 10 installer is relying on something other than hostid. Could it be that using hostid causes problems during remote installations? Is it possible the installer is actually looking for a physical file and not finding it in the location that it expects? Just an idea, but that's what you inquired about this time around. ;-) Good luck! Carl

My guess: the systems that Fabien works on at the moment run an application ("Maple 10") which requires each client to have a unique Host ID, like a digital serial number. 'man hostid' :-) regards, Carl

Hi Fabien, Maybe there is a setting in Ghost needed for it to generate a unique Host ID?

With hwinfo --all i can see all information about the hardware. Is it possible to find a command like hwinfo --reset-all ? May be... Le jeudi 5 octobre 2006 23:04, Carl Hartung a écrit :

With the "SuSE install" /etc/hostid does not exist I know hostid but how calculate the numeric value ? Le vendredi 6 octobre 2006 00:16, Carl Hartung a écrit :

Fabien,

You need to check for a difference between the "SUSE install" and the Ghosted install in the file /etc/hostid

Also, there are actually three commands pertaining to hostid:

sethostid gethostid hostid (all require superuser permissions)

Each has a man page, too. ;-)

Again, my first action would be to inspect what difference exists between the /etc/hostid file created during the SUSE install and the Ghosted installations.

I think I've run out of ideas, now. :-)

Good luck!

Carl

If you're in Paris, Fabien, send me a ticket and I'll come do it for you! ;-) I live in Lyon Let me make sure I understand this:

The 'original SUSE' (note it is all caps, now) installation does *not* produce an /etc/hostid file, but Maple 10 installs happily on the system.

Le vendredi 6 octobre 2006 00:52, Carl Hartung a écrit : the 'original suse does not produce an /etc/hostid file and Maple 10 installs happily on the system

The Ghost install /does?/ create an /etc/hostid file and Maple 10 will /not?/ install happily on the system?

The Ghost install does not create an /etc/hostid file and with or without this file Maple 10 will not install on the system

Am I understanding this correctly?

what use does the hostid have? It's for Maple 10

For example, i have the following adresse 134.214.141.188 Now, in hexa is 86.d6.8d.bc The host ID is : 0xd686bc8d I tried to explain : From the left, the fourth byte is permuted with the third byte From the right, the first byte is permuted with the second byte The name of the NIC of all ghosted pcs had eth1 or eth2. Maple ask eth0 I modify /etc/udev/rules.d/30-net_persistent_names.rules to have eth0 Now I can install Maple 10 !!! Thank in all people who help me.

It was originally *THE* hardware ID for a machine. Globally unique, hardwired into the machine. MAC addresses have largely taken over this function now nearly every machine has a network interface.

It was used for any purpose in the system that required a unique address. This included various software packages that wanted to lock licences to particular machines.

Over time, it became possible to change hostids, because it can simplify replacing a failed machine, for example, in the same way it became possible to change MAC addresses.

It's use by the system has gone away, so it's now just used by some dinosoar software licensing systems. Some include their own programs to generate a suitable ID.

Cheers, Dave
