is this x86_64?

birksworks · #1 8th October 2004, 09:34 PM

We've got a colocated Dual AMD Opteron Server on which Fedora Core 2 was installed by our vendor. I'd like to confirm that they installed the x86_64 version but so far I've only been able to see that:
OS = Fedora Core release 2 (Tettnang)
Version = Linux version 2.6.8-1.521smp (bhcompile@tweety.build.redhat.com)
(gcc version 3.3.3 20040412 (Red Hat Linux 3.3.3-7)) #1 SMP
Mon Aug 16 09:25:06 EDT 2004
Is there a simple way to check that this really is the 64 bit version fo Fedora Core 2?

Thanks,
Bob

try "uname -a" in a terminal

Thanks, Emily. uname -a gives:

>Linux gold.sightsoftware.com 2.6.8-1.521smp #1 SMP Mon Aug 16 09:25:06 EDT 2004 i686 athlon i386 GNU/Linux

but I'm not sure how to interpret this. I don't see anything suggesting 64 bit here and the "athlon" is not what I would expect. Can you tell me what I should get with this command if x86_64 were installed?

i686 is x86_64. I'm not sure, why there is also an i386, because this is the normal 32bit architecture.

when i run uname -a on my home machine which is an AMD Athlon(TM) XP1900+ with the 32 bit version of Fedora Core 2 installed, I get:

>Linux hawkins 2.6.8-1.521 #1 Mon Aug 16 09:01:18 EDT 2004 i686 athlon i386 GNU/Linux

which only differs from the above in the "smp" so the i686 can't mean x86_64, can it?

i686 is NOT x86_64
run

Code:

rpm -qa | grep kernel

and tell what it tells

birksworks · #7 8th October 2004, 10:38 PM

>rpm -qa | grep kernel

gives the following:

>kernel-source-2.6.5-1.358
>kernel-smp-2.6.5-1.358
>kernel-utils-2.4-9.1.131
>kernel-smp-2.6.8-1.521
>kernel-doc-2.6.5-1.358
>kernel-2.6.5-1.358
>kernel-2.6.8-1.521

In a normal x86_64 distro, "uname -a" shows:

Code:

Linux amadeu.essr.net 2.6.8-1.521 #1 Mon Aug 16 09:01:00 EDT 2004 x86_64 x86_64 x86_64 GNU/Linux

You're probably running the SMP kernel version, for you have 2 processors. But it's been compiled for the i386 architecture.

thanks, everyone. this resolves the issue. the vendor now admits to having installed the wrong version fo fc2.
