/proc/sysinfo has the complete information available through STS

Try reading the /proc/cpuinfo file.

/proc/sysinfo is much better but only available in up-to-date kernels.

how do I grab the IBM cpu id from a C program (which has no root privilege)?
Reinald
I was wrong.
I misunderstood the nature of gethostid()
and therefore misunderstood the relationship of 'hostid' to it.
Thanks to those who have indulged me in re-education.

I have spoken from experience rather than from the spec.
Here I am scratching my head trying to figure out why Willem and Alan
are confusing 'hostid' with gethostid(), and lo and behold
I see cross reference when I bother to read the man pages. Sorry.
HOWEVER:
hostid != gethostid

When I said it should be "retooled"
what I meant was that for some HW platforms (like zSeries)
there is a hardware concept of a processor serial number.
On such platforms, 'hostid' should report that value
or should report something derived from it
and not something derived from IP address or fi

On SuSE 7.0 the hostid file is /var/adm/hostid
Setting it is easy from root (I assume it checks for uid(0) rather than
root - haven't looked at the source yet) with `hostid 12345`. So I susp

"Retooled" is probably a somewhat "heavy" term for optionally
calling the sethostid function once during installation, which
will store its argument value in /etc/hostid, from where
gethostid will fetch it henceforth.

Just fyi, on OS/390 or z/OS 1.x, gethostid returns the 32 bit IP address
of the primary interface. Many applications written for the mainframe
expect this behavior.

'hostid' should probably be retooled for zSeries.
In my experience, it started with Sun where each motherboard
had (has) a unique serial number. Memory is a little fuzzy
but it was (is) probably tied to the MAC address (ethernet HW addr)
which followed (follows) the motherboard in many case

Subject: Hostid Value.
Hello,
We currently run Linux under VM (2.4.0) in LPAR on S390 G6 processor.
When we issue 'HOSTID - V' cmd we get a hex and a decimal value returned.
Can anyone tell us what this value means or is tak
Eric,
Try `man hostid`
On my SuSE Intel system (9.180.130.22) I get this:
root@silica ~> hostid -v
Hostid is 3020494466 (0xb4091682)

So hostid in that case is giving the, sort of, little-endian form of
9.180.130.22 (0x09B48216).

stack and we do not have a mac address which Linux running on an Intel
for example returns as the Hostid value. See example below of cmd issued on
Linux in a virtual machine.:-
hostid -v
Hostid is 134881268 (0x80a1ff4)
